3.1 INTRODUCTION ^
3.1.1 In order to develop optimally safe vessel operational criteria and a
pollution prevention program, the planning of a new or modified marine
terminal, or establishment of a transshipment site, to serve oil tankers,
liquefied gas, or chemical carriers requires the compilation and analysis of
diverse data sets. The presentation of the material should be in a form that
can be readily used by the TRC.
3.1.2 The selection of appropriate risk assessment models is dependent on the
nature of the project and the characteristics of the marine terminal
location or transshipment site and, since the TRC normally accepts the data
produced and the conclusions drawn from the studies developed, the proponent
is encouraged to discuss the selection of models with the TRC. In some
circumstances it may be necessary for a proponent to compile primary data,
rather than relying on existing information, on a specific topic in relation
to the site identified.
The statistical and other data sets necessary for the
studies and surveys identified in this Part may be obtained by the proponent
from a number of sources, some of which are identified in the respective
sections. Proponents are requested to use their own judgment in selecting
sources of required data and the best application of that data while keeping
in mind that the TRC may request additional information on any topic.
3.1.3 The proponent is encouraged to establish early informal contact with the
TCMS and relevant federal departments or agencies in order to gain access to
pertinent environmental data and advice. The applicable surveys, studies and
technical data, which are amplified in the sections that follow include:
- Origin, Destination and Marine Traffic Volume Survey;
- Fishing Vessel Operations Survey;
- Offshore Exercise and Offshore Exploration and Exploitation Activities
Survey;
- Route Analysis, Approach Characteristics and Navigability Survey;
- Special Underkeel Clearance Survey;
- Transit Time and Delay Survey;
- Casualty Data Survey;
- Ship Specifications;
- Site Plans and Technical Data;
- Cargo Transfer and Transshipment Systems;
- Channel, Manoeuvring and Anchorage Elements;
- Berth Procedures and Provisions;
- Single Point Mooring Provisions and Procedures;
- General Risk Analysis and Intended Methods of Reducing Risks;
- Port Information Book;
- Terminal Operations Manual;
- Contingency Planning; and
- Oil Handling Facilities Requirements.
3.2 ORIGIN, DESTINATION AND
MARINE TRAFFIC VOLUME SURVEY ^
3.2.1 The objectives of this survey are to quantify and describe all
recreational, commercial and any other traffic movement that collectively
form the regional marine traffic network. For this survey the proponent is
to identify:
- particulars of the types and sizes of ships operating in the region,
particularly those likely to be encountered by the design ship en route to
and from the proposed terminal or transshipment site;
- variations in traffic density statistics including those projected as a
result of the proponent’s vessels;
- special operational area (naval and airborne exercise areas, offshore
exploration and exploitation activities and seaplane activities);
- network focal point, or nodes, which indicate the geographical locations
where close-quarter situations are likely to occur and, particularly,
where there is crossing traffic;
- major fishing grounds and the periods they are used by fishermen,
pertinent data concerning species including spawning times and locations;
- major traffic routes including seasonal variations attributable to
climatic influences or other causes;
- sensitive biological and human environments along or adjacent to the
proposed routes, identifying sensitive species habitats, ecosystems, or
other human or biotic environments that may be particularly vulnerable to
contamination; and
- possible alternative routes for the design ship in light of the above
information and assessment of the experience of similar ships travelling
in the same or similar areas.
3.2.2 Possible sources of statistical data include the Coast Guard’s Marine
Communications and Traffic Services records, the Department of Fisheries and
Oceans, the Canada Ports Corporation, Harbour and Ports Directorates,
Statistics Canada, ferry schedules, and consultants reports. Sources of data
pertinent to the marine, terrestrial and human environments may include the
federal, provincial and municipal departments and agencies with
environmental and land-use mandates.
3.2.3 From this Survey the proponent may determine which of the possible
shipping routes offers the optimum navigational and operational safety and
poses the least threat to the human and biotic environment in relation to
any potential pollution incident.
3.2.4 A marine traffic network consists of one or more finite capacity waterways
leading to various marine terminals located in coastal zones or inland
waters. The flow of traffic within the network may be classified as:
- predictable flows comprising regular or predictable ship transits; and
- unpredictable flows comprising unscheduled or random ship transits.
Statistical counts of regional traffic for a particular
coastal region’s marine network over specified periods may be available
from CCG sources, or from marine consultants. Other marine activities often
superimposed on the regional traffic patterns could include:
- seasonal and year-round fishing activities;
- military exercises;
- recreational boating and sailing activities;
- offshore exploration and exploitation activities;
- ferry routes and schedules and
- seaplane activities.
Counts and supplementary data in respect to the above are
available from a variety of sources including several federal departments.
3.2.5 The shipping component of the proponent’s proposal will add to the
observed or estimated ship counts in some of the ship channels and coastal
routes within the existing regional network. The additions can be estimated
by considering both the proposed annual loading or receiving throughput for
the proposed marine terminal, and the mix of design ships in terms of the
minimum number of voyages per year required to meet the proposed annual
throughput volume. As the proposed marine terminal may either be an
importing or an exporting terminal, then the estimated additional ship
counts (voyages) should include an estimation of the incremental numbers
required to transship cargo to and from the terminal.
3.2.6 All of the considerations noted will apply to any proposed transshipment
site with the additional fact that any such designated site may limit the
capacity of the waterway to handle traffic flow by reserving a portion of
the area for the site.
3.2.7 A local marine traffic survey focuses on the immediate geographical area
of the proposed marine terminal. The objectives are to identify:
- particulars of the types and sizes of ships in the area of the terminal;
- particulars of local fishing operations;
- particulars of local recreational and other marine activities; and
- routing traffic support services in the terminal area and approaches.
Possible sources of statistical data include the Coast
Guard’s Marine Communications and Traffic Services records, port and
Harbour Master’s records, the Department of Fisheries and Oceans, local
marine recreational interests, and consultants reports.
3.3 FISHERY RESOURCES SURVEY
^
3.3.1 The objectives of this survey are to identify:
- fish and fish habitat including any sensitive marine areas which maybe
affected by the project;
- the geographical locations of regional fishing operations;
- the seasonal variations of fishing activities; and
- the customary routes to major fishing grounds from ports used by fishing
vessels.
3.3.2 Possible sources of statistical data are Fisheries and Oceans, provincial
departments of fisheries, and consultants reports.
3.3.3 Data collected for this survey may be used in conjunction with the Origin,
Destination and Marine Traffic Volume Survey.
3.4 OFFSHORE EXERCISE AND
OFFSHORE EXPLORATION AND EXPLOITATION ACTIVITIES SURVEY
^
3.4.1 The objectives of this survey are to identify:
- the geographical locations and frequency of use of military exercise
areas involving ships and aircrafts; and
- the geographical locations and frequency of offshore exploration and
exploitation and the routes used by offshore supply, seismic and survey
vessels.
3.4.2 Data concerning offshore exploration and exploitation activities can be
obtained from the companies concerned and Natural Resources Canada.
3.4.3 Data concerning military exercise areas can be obtained from the following
sources:
- depictions of exercise areas on nautical charts published by the
Canadian Hydrographic Service, Fisheries and Oceans Canada;
- Notice to Mariners No. 2, "Firing Practice and Exercise
Areas", in the annual edition of the Canadian Notices to Mariners,
published by the CCG; and
- the Director of Maritime Operations and Plans, National Defense
Headquarters in Ottawa.
3.4.4 Data collected for this survey may be used in conjunction with the Origin,
Destination and Marine Traffic Volume Survey.
3.5 ROUTE ANALYSIS, APPROACH
CHARACTERISTICS AND NAVIGABILITY SURVEY
^
3.5.1 In accordance with the stated intent of the TRP, the objectives of this
survey are to assess ship and route safety, the adverse effects of ship
accidents and, when applicable, public safety matters associated with the
transportation of bulk oil, liquefied gas, chemicals or other identified
cargoes in ships that serve the marine terminal system or transshipment
site. The Route Analysis, Approach Characteristics and Navigability Survey
is therefore a major component of the review. The survey should be
considered in terms of the design ship’s applicable characteristics, the
physical characteristics of the approach route to the terminal or
transshipment site and prevailing atmospheric factors. The components of the
survey are:
- to confirm that the loaded design ship can safely navigate the channel,
or channels, between the proposed marine terminal or transshipment site
and its coastal approaches, or vice versa. (As a rule of thumb the survey
should commence at the termination of the ship’s ocean passage, at the
first landfall, or seabuoy {inbound} and terminate at the commencement of
the ship’s ocean passage {outbound}.)
- to identify hydrographic factors which could adversely affect the safety
of the design ship (e.g., tides);
- to identify the suitability, if any, of alternative routes to the
proposed marine terminal or transshipment site;
- to identify any climatic or oceanographic factors which adversely affect
navigational safety;
- to identify any navigational hazards or ship manoeuvring problems along
the route;
- to identify any physical limitations along the route (e.g. bridges,
power transmission lines, narrows, bars etc.);
- to identify the need, if any, for proposed improvements to existing aids
to navigation or vessel traffic services;
- to identify the need, if any, for escort / assist tugs;
- to identify the coastal communities located close to the intended route;
- to identify the geographical locations of suitable emergency and holding
anchorages for the design ship;
- to provide a depicted base of collations with data acquired for the
Origin, Destination and Marine Traffic Volume Survey, the Offshore
Exercise and Offshore Exploration and Exploitation Activities Survey and
the Fishing Vessel Operations Survey; and
- to identify supplemental, but significant, matters such as the
geographical location of the pilot station, the regional
radiocommunications infrastructure, and any other relevant matters of
interest to the proponent or the TRC.
3.5.2 The design ship is required to carry the appropriate charts and nautical
publications in accordance with the Charts and Nautical Publications
Regulations, when navigating in waters under Canadian jurisdiction. A
list of the required charts and publications and acceptable equivalents is
contained in the annual edition of the Canadian Notices to Mariners,
published by the CCG. This document is also required to be carried on all
vessels entering waters under Canadian jurisdiction.
3.5.3 The design vessel is required to comply with the Navigating Appliances
and Equipment Regulations when in waters under Canadian jurisdiction.
These regulations require vessels to be fitted with specific navigational
equipment appropriate to the area in which the vessel is navigating. The
proper use of such equipment, as addressed in the Canadian Watchkeeping
Standards, provides guidelines for the mariner to navigate effectively
and safely in all weather conditions, in darkness, and during the oceanic,
coastal, and pilotage phases of the voyage thereby ensuring both vessel
safety and pollution prevention. This Code or its equivalent is also
required to be carried on all vessels entering waters under Canadian
jurisdiction.
3.5.4 Data Sources for the Route Analysis, Approach Characteristics and
Navigability Survey include:
- applicable nautical charts, published by the Canadian Hydrographic
Service, Fisheries and Oceans Canada, as listed in the annual edition of
the Canadian Notices to Mariners (see section 3.5.2, above), and
other required nautical publications also cited therein, including:
- radio aids to marine navigation,
- sailing directions,
- list of lights, buoys and fog signals, and
- tide and current tables;
- Ocean Sciences and Surveys, Fisheries and Oceans Canada for
oceanographic and iceberg data;
- The Atmospheric Environment Service, Environment Canada for climatic
data and for data on ice covered waters; and
- Consultants’ reports.
3.5.5 The annual edition of the Canadian Notices to Mariners provides
additional information on various other regulatory initiatives that may
affect the safety of the ship.
3.6 SPECIAL UNDERKEEL CLEARANCE
SURVEY ^
3.6.1 The objective of this survey is to consider all relevant factors which may
affect underkeel clearance and to ensure that the design ship has an
adequate underkeel clearance at all times as outlined in section 3.6.2
3.6.2 Nominally, the design ship’s minimum underkeel clearance should be
fifteen percent of its maximum permissible draught or meet the requirements
established and published by the appropriate government authority for a
specific waterway. A proposal for a minimum underkeel clearance in the
approach of less than fifteen percent of the design ship’s deepest draught
will be considered, but the proposal should be supported by explicit
operational details and calculations associated with each of the following
factors:
- minimum chart datum measurements supplemented with tidal heights over a
specified time base;
- the accuracy of predicted tidal heights and the predicted times of high
water and low water;
- details of any tidal surges and wind set-up;
- the allowances made for the degree of accuracy in the hydrographic
survey (chart datum) and for dredging tolerances;
- the incidence and degree of channel silting between maintenance
dredgings and the identification of all critical depth areas;
- the increase in effective draught due to the rolling, pitching, and
heaving of the ship under wave action within the ship channel and at the
terminal or transshipment site;
- the estimated squat for the design ship calculated for each critical
depth area based on the maximum permissible operating ship speed in the
area and the most constricted channel section within the critical depth
area;
- the effects of sagging or hogging;
- the nominal trim and changes of trim experienced by the design ship;
- draught and trim changes attributed to any changes in water density;
- any climatical and related depth anomalies;
- nature of the bottom;
- allowance for maneuverability in shallow water; and
- an operational plan to ensure safe transit.
3.7 TRANSIT TIME AND DELAY SURVEY
^
3.7.1 The objective of the "transit time" component of this survey is
to determine the safest coastal zone and/or inland waterway speed profile
for ships proceeding to and from the proposed marine terminal or
transshipment site. The objective of the "delay" component of this
survey is to determine the probable causes, locations, durations and the
frequencies of delays in the movements of marine traffic through a ship
channel or ship channels connecting the coastal approaches and the proposed
marine terminal or transshipment site. The methods of ascertaining this
information may include:
- conclusions drawn from the Route Analysis, Approach Characteristics and
Navigability Survey;
- completing a simulated or actual test run, or runs, using a ship similar
to the design ship;
- the use of questionnaires distributed to selected ship masters;
- advice from the applicable Pilotage Authority; and
- data maintained by CCG Marine Communications and Traffic Services.
3.8 CASUALTY DATA SURVEY
^
3.8.1 As the breaching of a ship’s cargo containment system, or hull, is
usually attributable to a grounding or a collision, the object of this
survey is to develop a means of calculating the likelihood or probability of
such an occurrence through the analysis of statistical casualty data within
terms of:
- the mathematical probability of casualties in the future taking into
account the additional traffic within the regional zone of the proposed
marine terminal or transshipment site;
- the inferred vulnerability of the design ship over a specified period of
time; and
- the inferred vulnerability of the marine environment or of communities
located close to the intended ship route.
3.8.2 Casualty data surveys involving releases of cargo in bulk should not be
confined to those attributable to collisions and grounding but should
include a listing of small scale incidents and the effects of these
releases.
3.8.3 The application of the inferential statistical methodologies is a
recommended approach to this survey. Sources of casualty data applicable to
this survey include:
- Classification Societies;
- P&I Clubs and underwriters;
- Transportation Safety Board casualty records or summaries;
- U.S. Coast Guard casualty records or summaries;
- I.M.O. summaries;
- CCG Marine Communications and Traffic Services records; and
- consultants reports.
3.9 SHIP SPECIFICATIONS

the proponent upon request.
3.11 CARGO TRANSFER AND
TRANSSHIPMENT SYSTEMS ^
3.11.1 The objective of this survey is to assess the suitability of the
arrangements for transferring the cargo from ship to shore (or vice versa)
or from ship to ship. To this end, the proponent is expected to provide the
TRC with plans and descriptions of the design ship’s cargo containment and
transfer systems including, for purposes of continuity, the important shore
components.
3.11.2 The following nominal listing of preferred data is provided for general
guidance. The proponent should, however, be guided by applicability and
continuity of descriptions:
- general details of cargo pipelines and hoses connecting the ship to the
marine terminal;
- intended rating of cargo transfer pumps;

chemical carriers; and
- special arrangements required by the nature of a particular substance
being handled / transferred.
3.11.3 If it is the proponent’s intention to install an automated stability
calculation and cargo transfer control system in the design ship, then an
abstract of the system’s capability and limitations should be included in
the proponent’s submission including the relevant details of the design
ship’s stability characteristics and the approval Authority.
3.11.4 The proponent should adhere to the procedures provided in the latest
version of the Cargo Transfer Safety Checklist System for Tankships as
contained in Appendix 1. Alternative procedures may be considered through
consultation with the TRC concerning cargoes not covered by this checklist
system, however, the general principles and objectives of the checklist
system should apply.
3.12 CHANNEL, MANEUVERING AND
ANCHORAGE ELEMENTS ^
3.12.1 The objectives of this study are to determine the suitability of existing
channels for the design ship(s) and to identify those areas of concern where
navigation requires particular attention.
3.12.2 The guidelines provided in Appendix 2 are based on optimum operational
conditions, and an accurate system of marine aids to navigation being in
place. Proposed ship channels, anchorages and emergency containment areas
should be depicted on large scale nautical charts or engineering plans.
3.13 BERTH PROCEDURES AND
PROVISIONS ^
3.13.1 The objective of this study is to determine whether the berthing
provisions are adequate for the design ship(s). Berths and moorings should
be capable of handling the full range of ships the terminal is intended to
accommodate under normal operating conditions. The proponent is responsible
for demonstrating, through simulation or other means, the suitability of
berths and moorings to safely accommodate the design ships which will use
them. Suggested criteria and guidelines for these facilities are included in
Appendix 3.
3.13.2 Calculations of the loads imposed on the various components and structural
elements of the terminal berths should include, but not be limited to, the
following forces and appropriate combinations thereof applicable to each
structural element:
- dead loads of all piping, mechanical equipment, their liquid contents,
superstructures and supporting structures;
- berthing forces arising from normal fender thrusts and horizontal and
vertical frictional shear forces;
- mooring forces arising from wind, current, ice and wave pressures on
largest ships in ballast and full displacement conditions at the extreme
operating conditions;
- seismic forces from any horizontal direction computed for the dead loads
and superimposed static loads, as well as seismic loads transmitted
through pipeline anchors. Seismic forces should be computed in accordance
with the methods specified in the National Building Code and for piled
structures, seismic forces should be assumed to be concentrated at the
deck elevation;
- temperature loads due to thermal expansion and contraction of the
structures including those transmitted through pipeline anchors;
- wind load on the structures, superstructures and equipment;
- wind, wave and ice pressures on components of structure. Wind and wave
forces should be based on a storm loading having average expected
recurrence interval of 50 years;
- live loads of moving vehicles and cranes and,
- earth fill and hydrostatic pressures
Each structural component should be proportioned to
resist bending and shear in two directions, torsion and axial forces.
3.13.3 Each structure should be analyzed for combination of permanent loads and
transient peak loads. In general, allowable stresses and design procedures
should conform to the National Building Code requirements. Increased
allowable stresses may be considered depending on the probable recurrence of
the loading, the load duration and the corresponding risk factors.
3.13.4 Detailed consideration of intended berthing strategy should be an integral
part of the Route Analysis, Approach Characteristics and Navigability
Survey. The following guidelines are provided for the proponent’s
consideration:
- determine the upper limits of wind velocity for design ship berthing
operations - arrivals and departures;
- determine the wind velocity which would require the design ship to
vacate the berth;
- determine any other limiting environmental / operational criteria;
- provision of speed of approach measurement devices and a means of
communicating this information to the berthing vessel;
- ascertain maximum current measurements in the vicinity of the berth and
its effect on berthing operations;
- ascertain tidal range, velocities and directions and the maximum
recorded spring tide measurements;
- ascertain prevailing wind statistics in relation to the directional lie
of the berth;
- consider the effects, if any, of bathymetry in the vicinity of the berth
and its approaches, on berthing strategy;
- consider berth loading and dolphin fendering aspects;
- consider the use of mooring points, mooring techniques, quick release
hooks, and mooring line monitoring systems; and
- determine the method of docking and undocking the design ship and the
number of tugs, if required.
3.13.5 When berthing ships of 65,000 deadweight tonnes or over, it is recommended
that the proponent give favourable consideration to the use of:
- two mooring launches;
- sufficient linesmen forming fore and aft mooring gangs; and
- intrinsically safe UHF and VHF radio transceivers for two way
communications between the ship’s bridge and mooring personnel.
3.13.6 It is incumbent upon the terminal operator to provide adequate reception
facilities.
3.13.7 The safety of the ship and the terminal berth may be threatened by the
simultaneous transfer of some bulk cargoes and ship’s stores. The
proponent’s intentions in this regard are of particular interest to the
TRC. Accordingly, the proponent is required to submit plans in relation to
the safety and security of the ship and its personnel while alongside the
berth.
3.14 SINGLE POINT MOORING
PROVISIONS AND PROCEDURES ^
3.14.1 The objective of this study is to determine the suitability of any
proposed single point mooring (SPM) for the design ships intending to use
it.
3.14.2 A TRP submission which proposes the use of a SPM, whether a buoy or a
tower, should include:
- the geographical coordinates of the intended location;
- the rationale for the site selected;
- the relevant design details and the standards employed in the design;
- the integral piping; and
- the ship securing components.
3.14.3 The proponent should outline the operational guidelines relevant to the
SPM design specifications. A proposal to position a SPM in ice-covered
waters would require special consideration by both the proponent and the TRC.
3.14.4 A single point mooring system should not be sited close to shipping routes
or anchorage areas.
3.14.5 Design loads, based on an average expected recurrence interval of 50 years
should be calculated for the various components of the SPM (buoy or tower)
using the most adverse combinations of forces generated by wind, wave,
current, ice accretion, dead loads, surge, drag, collision, and wave wash
that are within the operating criteria. Mooring forces should be derived
with the aid of model tests and/or computer analysis. Model tests may also
be required to evaluate the overall stability, dynamic behaviour and
interaction of the system components under all design loading conditions.
3.14.6 The proponent must outline connect and disconnect procedures taking into
account environmental and operational criteria.
3.14.7 Special consideration should be given in
the design of component connections, moving parts and fittings to fatigue,
wear, freeze-up and binding. All components should be designed so that they
are readily accessible for inspection and maintenance. Specific details
concerning a SPM are given in Appendix 4.
3.15 GENERAL RISK ANALYSIS AND
INTENDED METHODS OF REDUCING RISKS
^
3.15.1 The objective of this study is to review the proponent’s analysis of any
risk or risks relating to uncontrolled releases of pollutant cargoes (oils
and chemicals) and hazardous cargoes (liquefied gases and some chemicals)
either en route or at a terminal or transshipment site. These usually stem
from a scenario involving;
- a two ship collision;
- a ship grounding;
- a ship striking a fixed object;
- an improper cargo transfer incident, or
- a fire or explosion.
Predictions should be based on a "worst case",
but credible accident scenario in the terminal area and at selected
positions along the coastal route.
3.15.2 The proponent’s risk assessment should include:
- the probabilities of credible incidents which result in the breaching of
the ships cargo containment system;
- the risks associated with navigational and operational procedures;
- the probabilities of a major cargo transfer incident at the terminal
dock;
- the geographical boundaries and the resulting consequences of an
uncontrolled release of cargo on the marine environment and, when
applicable, in the close vicinity of adjacent coastal communities; and
- the risk of an incident becoming "uncontrollable".
3.15.3 Threats to the marine environment and, in some instances, to public
safety, following the uncontrolled release of bulk cargo into the sea from a
ship are based on:
- downwind and crosswind dispersions of flammable gases or, in some
instances, the downwind dispersion of toxic gas plumes; or
- the trajectory of oil spills reacting to wind and current actions; or
- the mixing of chemicals with water including applicable chemical
reactions, and the resulting dispersions of chemicals in the water
columns.
3.15.4 Analysis should not be limited to a mathematical index (probability of an
incident) but should also include perceived risks to:
- populations within coastal zones along the intended route;
- the terminal berth and surrounding area; and
- the marine environment, fish and wildlife habitat.
3.15.5 Appendix 5 provides representative tables of contents for risk analysis of
oil, chemical and liquefied gas cargoes and other related information for
the proponent’s consideration.
3.15.6 When the watertight integrity of an oil tanker’s hull is breached, the
cargo may be released. In the case of "double hulled" tankers the
incidence of released oil from the cargo containment system may be less
likely following a grounding and some collisions. The proponent’s risk
assessment and oil spill contingency plan should include details of
intentions concerning:
- predictions of nominal oil spill trajectories and oil weathering for a
specified worst-case credible incident at the terminal berth, at a
transshipment site, and at appropriate coastal locations along the
navigational route, taking into account the particular circumstances of
the proposed site including, but not limited to:
-
- environments of particular ecological sensitivity;
- human habitation;
- recreational activities;
- local or regional economic considerations; and
- aspects of social or cultural significance;
- in developing predictions of nominal oil spill trajectories, reference
should be made to studies of prior incidents involving identical or
chemically similar petroleum products;
- any predictions should reference any laboratory research conducted on
the behaviour of the petroleum product in simulated environmental
conditions;
- planned counter-measures for an oil spill containment, clean-up,
restoration and public safety at the locations identified above,
including:
-
- on-shore and on-ship resources, such as equipment and clean-up
vessels, neutralizing / dispersant materials and human resources, which
the ship’s crew can access; and
- response organizations and their response capabilities; and
- the Declaration as required by the Oil Pollution Prevention
Regulations;
- logistical considerations applicable to situations suggested above.
3.15.7 The Canada Shipping Act requires all oil spills originating from
ships to be reported immediately to a Pollution Prevention Officer. The
polluter has statutory obligations to repair, remedy, minimize or prevent
pollution damage and for costs incurred to prevent actual or anticipated
pollution damages resulting from a spill. The CCG will monitor the conduct
of countermeasures and assume command and control if, in view of the
Canadian Coast Guard, the polluter is unable to protect the public interest.
3.15.8 When the watertight integrity of a chemical and other noxious substances
carrier’s hull is breached, the cargo contained may be released. The
proponent’s spill risk analysis and prevention/contingency plan should
include the following:
- predicted reactions following the mixing of released cargo(es) with
water, with other cargo chemical(s), or with substances required for
normal vessel operations;
- predicted chemical, biotic or metabolic, and photo-chemical
transformations once the released cargo(es) enters the environment;
- toxicity of individual cargo chemicals and potential products formed by
the combination of these chemicals with themselves or water to marine
mammals, other marine life, and human life;
- chemical incompatibility of cargo(es) and the measures that will be
taken to reduce the risk of potentially dangerous combination products
developing upon release;
- the proponent’s countermeasures for containment, clean-up, restoration
and, where applicable, public safety alongside the berth, at the
transshipment site, and at appropriate locations along the intended route.
3.15.9 There is a need to model gas plumes in certain circumstances. The
technological basis for modelling large liquefied gas vapour clouds is
constantly evolving. The selection of a particular gas cloud model should be
made in consultation with the TRC. Any risk or dispersion model should
include an analysis of the sensitivity of varying the assumptions or values
input into the model. Appendix 6, "Representative Gas Cloud
Models", lists a number of models currently used in predicting
exercises. Predictions of specified gas cloud dimensions must be based on
defined, worst-case, credible incidents involving the
"instantaneous" release of one cargo tank at selected locations
along the route and at the terminal or transshipment site.
3.15.10 The determination of the risk to public safety within a port that has been
selected as the site of a liquefied gas marine terminal or surrounding a
transshipment site normally requires the determination of four parameters:
- the vulnerability of the liquefied gas carrier’s cargo containment
system following a collision or grounding within the specified marine
area;
- the probability of a liquefied gas release within a specified marine
area;
- the "nominal" quantity, rate and duration of released
liquefied gas bulk cargo and the dimensions of the resulting vapour cloud;
and
- the proximity of populations to vapour cloud boundaries and the
distribution of possible ignition sources.
3.15.11 A deflagrating vapour cloud could be the cause of fatalities and of
property damage within its boundaries. In addition, the threat of radiation
burns exists in the peripheral area of an ignited vapour cloud. Detonations
with lethal overpressures are possible if vapour collects in confined spaces
before ignition. The quantification and evaluation of these risks is a
complex process and there does not appear to be any one measure that is
uniformly accepted. An acceptable approach would be to calculate the risk of
fatalities in terms of exposed persons per unit of time.
3.15.12 Amelioration or mitigation of perceived risks is an essential
consideration in any TERMPOL submission. The particulars will vary depending
on the proposal, however, it is possible to list a number of examples:
- implementation of safe navigational / operational systems and
development of a pro-active pollution prevention program;
- locating the terminal in a remote location or one which is well
separated from urban or suburban communities;
- designing and constructing or chartering ships with the safest possible
cargo containment and cargo transfer systems;
- the application of recognized and effective maritime mobile radio
procedures which enhance safety in international, coastal, and inland
waters;
- routing ships with hazardous cargoes clear of primary shipping lanes and
major shipping focal points when possible to reduce the incidence of
close-quarter situations;
- recommending additional aids to navigation which individually or
collectively improve navigational safety along the intended route;
- schedule liquefied gas or chemical carrier movements through congested
coastal waters to coincide with periods when traffic is normally at a
minimum, if this is possible;
- implementing recognized and effective vessel traffic services which
enhance ship safety in coastal regions. These include the monitoring of
traffic movements, regulated speed profiles, warning broadcasts, and the
regulation of ship movements in critical portions of the route to provide
a clear channel for the design ship;
- imposing limiting environmental or climatic requirements for ships
loaded with pollutant or hazardous cargoes when navigational safety within
the terminal zone is an issue;
- tug escort;
- implementing prudent berthing procedures and optimal tug assistance;
- employing an energy absorbing protective barrier when alongside the
terminal;
- manning ships with fully competent crews adequately trained for the
particular cargo(es) they handle and the design ship they operate;
- keeping sufficient crew onboard at all times while a ship is
transferring hazardous cargoes so that the ship is capable of getting
underway at short notice;
- mooring a ship transferring hazardous cargoes bow seaward when the
terminal berth is located in a narrow arm of water so that in an
emergency, the ship can proceed seaward without delay and without the aid
of tugs;
- the implementation of standardized cargo transfer system inspections and
safety-oriented cargo transfer operations;
- the promulgation of standardized safety and cargo transfer procedures by
means of port information publications designed to inform crews of ships
serving the proposed marine terminal. The procedures should include
specified upper climatic limits for berthing operations, for stopping
cargo transfer operations, and for vacating the berth;
- prohibiting the venting of significant quantities of flammable or
poisonous gases to the atmosphere in the vicinity of human habitations;
- the provision of appropriate reception facilities at chemical and oil
terminals;
- scheduling the bunkering and provisioning of ships transferring
hazardous cargoes to a time that does not conflict with the maintenance of
ship and personnel safety during cargo transfer operations;
- controlling the access of visitors while the ship is alongside the dock;
- the development and promulgation of an effective contingency plan for
the marine terminal system and the regular exercise of selected procedures
described in the plan;
- having procedures in place which conform to internationally accepted
safe management practices as implemented through IMO resolutions, ISM
and/or ISO standards; and
- a ship when chartered by the proponent is required to comply with
appropriate chartering standards, be of the same standard and meet the
same requirements of the design ship as described here in.
3.16 PORT INFORMATION BOOK
^
3.16.1 The purpose of the Port Information Book is to provide ship’s personnel
and other interested parties with all the relevant details pertaining to the
specific route to, and about, the marine terminal system or transshipment
site. Much of this information can be derived from the surveys required for
the TRP. Items to be covered include, but are not limited to, the following:
- berthing strategy in terms of the design ship’s approach and departure
from the terminal berth; tug assistance requirements; mooring assistance
requirements; the upper limit of lateral approach rate to the berth by the
design ship and the means of measuring and indicating wind speed and the
ship’s lateral approach rates;
- upper limits of berthing operations in term of wind velocity, wave
heights, tidal stream velocity, ice cover, visibility, and the means of
measuring and indicating these factors;
- the upper wind velocity limits which would necessitate the cessation of
cargo transfer operations and cause the departure of the ship from the
berth;
- load measurements and limits for mooring lines and dockside bollards
used by large ship/carriers;
- pilots, tug assistance details, procedures for mooring boats, line
handlers and the means of communications between ship / tugs / berthing
superintendent and mooring boats;
- ship machinery and equipment repairs facilities;
- storing and bunkering facilities;
- security and industrial safety matters;
- vessel reporting procedures;
- pilot boarding procedures;
- ship / shore communications procedures;
- designated anchorages; and
- emergency measures.
3.16.2 Because ship personnel and the terminal’s cargo transfer staff are
separated during much of the preparatory phase of a scheduled cargo transfer
operation, the Port Information Book should include an explicit schedule of
required communications to be initiated by the master of the ship. The text
of the transmission should enable the marine terminal operator, the ship’s
agent, the harbour master, the pilotage authority, the Coast Guard and
Marine Safety to be informed, in a timely manner, with needed information.
The timing of the scheduled messages should take into account the common
administrative delays in message handling and message distribution in other
than direct ship / terminal communications.
3.17 TERMINAL OPERATIONS MANUAL
^
3.17.1 The purpose of the Terminal / Transshipment Site Operations Manual (TOM)
is to inform and to guide the crews of ships calling at the proponent’s
terminal or transshipment site of important subject matters which affect the
safety of the ship, the terminal or transshipment site itself, and the
efficiency of the ship’s cargo transfer operations. It should be noted
that, while a ship may call at a particular terminal or transshipment site
for many years, ship’s crews change frequently and it is the crew who play
the primary role in ensuring ship safety during transfer procedures.
3.17.2 The TRC recognizes and appreciates the technical and economic reasons for
not producing the complete text of a TOM before the terminal or
transshipment site has received regulatory approvals and, in the case of a
marine terminal system, before construction has commenced. Nevertheless the
TRC is of the opinion that the importance of the substance of the
information which comprises the TOM is such that it should receive early
attention by the proponent’s planning staff. The list of subject matters
which follow should be considered as a nominal listing:
- inspections, testing and preventative maintenance of terminal berth
equipment used by ships;
- pre-arrival and departure operational tests and checks of ship’s
machinery and equipment;
- cargo pre-transfer inspections, checklists, and conferences;
- ship-terminal hose-manifold connections; ship-terminal communications
and chain of authority;
- cargo handling procedures including emergency shut-down procedures;
- safety precautions and ship oriented emergency procedures which would be
included in the terminal’s contingency plans;
- receiving facilities for ballast, dirty ballast, slops and garbage.
3.18 CONTINGENCY PLANNING
^
3.18.1 The primary purpose of contingency planning is to be prepared to respond
to abnormal events when they occur. The effectiveness of any contingency
plan also depends on the personnel regularly exercising their respective
roles and responsibilities. The TRC expects the proponent to provide a
preliminary outline for the intended contingency plan for review as it
relates to a ship in transit and/or alongside the proposed marine terminal
berth or transshipment site. The review of the contingency plan enables its
collation with Coast Guard and Marine Safety Emergency Operations Procedures
in order to ensure an integrated response, if and when required.
3.18.2 Topics to be included in a ship-oriented contingency plan while a vessel
is en route to, from or at the terminal or transshipment site should deal
with:
- incidents involving the release of cargo(es)
- fire and explosions;
- operations monitoring systems;
- terminal-ship communications;
- inspection, testing, and preventative maintenance procedures;
- cargo handling precautions applicable to the ship;
- neutralizing electrical hazards;
- detection and alarm systems at the ship’s berth;
- emergency shut-down of cargo transfer operations;
- emergency responses to incidents involving the uncontrolled release of
cargo(es) at or near the ship’s berth or transshipment site during cargo
transfer operations;
- countermeasures which ameliorate, contain or neutralize the harmful
effects of cargo released into the marine environment;
- outline of personnel emergency equipment proposed for berth area and the
evacuation procedure for personnel;
- emergency procedures which would require the vacating of the terminal
berth and the disposition of the vessel; and
- security at the ship’s berth.
3.18.3 Those aspects of the terminal-oriented contingency plan of interest to the
TRC focusing on the ship alongside could include the following situations:
- fire in the engine room, compressor, deck stores or ship’s
accommodation spaces;
- releases resulting in structural damage and/or personnel injuries;
- equipment malfunctions;
- rapidly deteriorating weather conditions and possible evacuation of the
berth;
- grounding or collision at or near berth;
- fires on dockside, pipelines in the immediate vicinity of the berth, and
the tank farm; and
- sabotage.
3.18.4 Procedures relating to incidents which require active responses from the
ship’s personnel should be explicit, succinct, unequivocal, and
communicated in the operational language(s) of the ship. The ship’s
personnel should be aware of the terminal-ship chain of command and of
emergency drill requirements and procedures and be able to communicate with
the terminal’s personnel.
3.18.5 The proponent must prepare a study showing the extent to which an incident
would likely have an adverse effect upon third party interests and how the
proponent would address this through remediation and/or compensation.
3.19 OIL HANDLING FACILITIES
REQUIREMENTS ^
3.19.1 Pursuant to chapter 36 Part XV of Canada Shipping Act, article (4), the
operator or an oil handling facility that is designated pursuant to
subsection (8) shall:
- Comply with regulations respecting the procedures, equipment and
resources that an oil handling facility must have on site for use in
respect of an oil pollution incident at the oil handling facility, where
the incident arises or of the loading and unloading of oil to or from a
ship at the oil handling facility;
- Have an arrangement with a response organization to which a certificate
