PREVIOUS | TABLE OF CONTENTS | NEXT PART VII 66. The entire sides, ends and bottom of every new oil barge that operates in Canadian
waters, or in any fishing zone of Canada prescribed pursuant to the Territorial Sea and
Fishing Zones Act, shall be protected within the cargo tank length by spaces that (a) are dimensioned in accordance with sections 68 and 69 of these Standards, and (b) do not contain oil, unless the oil barge is of an alternative design which, in the opinion of the Board,
provides equivalent environmental protection. 67. (1) Every existing oil barge that operates in Canadian waters, or in any fishing
zone of Canada prescribed pursuant to the Territorial Sea and Fishing Zones Act,
shall comply with the requirements of section 66 as if it were a new oil barge, or be
withdrawn from bulk oil transportation service (a) if of less than 5000 gross tons, no later than January 1st, 2015; or (b) if of 5000 gross tons or more, in accordance with the time schedule applicable to
single hulled tankers of like tonnage. (2) The requirements of subsection (1) do not apply to any existing oil barge that (a) is of less than 2000 gross tons; (b) has no cargo tanks that exceed 200 cubic metres capacity; and (c) operates solely on the Mackenzie River, those waters contiguous to the river not
within Arctic Shipping Safety Control Zone 12, or on a river or lake that feeds into the
Mackenzie River. (3) Every existing oil barge that is converted by the addition of side tanks, peak
tanks or double bottoms to achieve the double hull requirements of section 66 shall be
considered a new oil barge with respect to the application of these Standards. Dimensions of Protective Spaces ^ 68. (1) The moulded side tank width of any oil barge, measured at right angles to the
shell plating, shall in no location be less than W metres, where (a) for oil barges of 5000 tonnes deadweight (DWT) and above,
(b) for oil barges of less than 5000 tonnes deadweight (DWT),
(2) The moulded double bottom height of any oil barge of less than 5000 tonnes
deadweight that operates only in Canadian waters and the fishing zones of Canada
prescribed pursuant to the Territorial Sea and Fishing Zones Act, not more than 40
miles offshore, shall in no location be less than the side tank width determined in
accordance with subsection (1). (3) The moulded double bottom height of any oil barge of 5000 tonnes deadweight or
above, and of any oil barge of less than 5000 tonnes deadweight that operates beyond the
limits described in subsection (2), shall comply with the requirements for oil tankers
established by Canadian Coast Guard Standards for the Double Hull Construction of Oil
Tankers, TP11710E. (4) Notwithstanding the requirements of subsections (2) and (3), cargo tank drainage
wells may be constructed in the double bottom provided they (i) are as small as practicable; and (ii) in no case extend below the tank top for a distance greater than half the double
bottom height. (5) Every side tank and double bottom tank shall be constructed to provide adequate
access for inspection and maintenance purposes. (6) Ballast piping and other piping such as sounding and vent piping to ballast tanks shall not pass through cargo tanks, nor shall cargo piping and piping to cargo tanks pass through ballast tanks, except that short lengths of piping may be permitted provided that they are completely welded. 69. (1) No oil barge cargo tank shall extend forward of a transverse plane located at
the lesser of (a) 0.05 x length (L); and (b) 7.5 metres measured aft from the outside of the stem plating at freeboard deck level. (2) No oil barge cargo tank shall extend aft of a transverse plane located at a
distance equal to the required side tank width, measured forward from the outside of the
stern plating at freeboard deck level. (3) Notwithstanding subsection (2), where an oil barge is fitted with a stern notch, no part of a cargo tank containing oil shall extend closer to the notch than a distance equal to the required side tank width.
