Fishing Vessel Safety Regulations — 10
10 (1) A fuel tank on a fishing vessel that is separate from the hull shall comply with the following rules: (a) it shall be made of steel or other suitable material the strength of which is equivalent to that of steel; (b) where a fuel tank is made of material other than steel and the vessel is a steel vessel, the fuel tank shall be efficiently isolated from the steel structure of the vessel; (c) where a fuel tank is made of steel, the steel plating shall have a minimum thickness calculated in accordance with the following table: TABLE Capacity of tank in litres Minimum thickness of steel plating in millimetres More than 114 and not more than 1 364 3 More than 1 364 and not more than 4 550 5 More than 4 550 6 (c.1) where a fuel tank is made of material other than steel, the material used for plating shall be of such thickness as to provide a strength equal to or greater than the strength of the steel plating required in accordance with paragraph (c); (c.2) subject to paragraph (c.3), where the capacity of a fuel tank is more than 114 L, the tank is made of steel and the thickness of the plating is the thickness set out in Column I of an item of the table to this paragraph, the tank shall be fitted with stiffeners so that the unsupported flat surfaces of the tank do not exceed, in square metres, the area set out in Column II of that item: TABLE Column 1 Column 2 Item Thickness of steel plating in millimetres Unsupported flat surface area in square metres 1 3 0.28 2 5 0.56 3 6 0.84 (c.3) where the thickness of the tank plating is intermediate to any set out in the table to paragraph (c.2), the unsupported flat surface area shall be calculated by interpolation and, where such thickness exceeds 6 mm, the unsupported flat surface shall be calculated in accordance with that table by extrapolation; (c.4) subject to paragraphs (c.5) and (c.6), where the capacity of a fuel tank is more than 114 L, the tank is made of material other than steel and the thickness of the tank’s plating is such as to provide a strength equal to or greater than the strength of steel plating having a thickness set out in Column I of an item of the table to paragraph (c.2), the tank shall be fitted with stiffeners so that the unsupported flat surfaces of the tank do not exceed, in square metres, the area set out in Column II of that item; (c.5) where the thickness of the tank plating made of material other than steel is such as to provide a strength equal to the strength of steel plating referred to in the table to paragraph (c.2) and is intermediate to any set out in that table, the unsupported flat surface area shall be calculated by interpolation; (c.6) where the thickness of the tank plating made of material other than steel is such as to provide a strength that exceeds the strength of 6 mm of steel, the unsupported flat surface area shall be calculated in accordance with the table to paragraph (c.2) by extrapolation; (d) where the length or breadth of a fuel tank is greater than 1.22 m, baffle plates shall be fitted inside the tank in sufficient numbers that the distance between baffle plates or between a baffle plate and a side plate is not greater than 1.22 m; (e) a fuel tank having a capacity exceeding 1 364 L and not exceeding 4 550 L shall be fitted with a suitable clean-out door, and a fuel tank having a capacity of more than 4 550 L shall be fitted with a manhole door; (f) where the capacity does not exceed 114 L it may be constructed of material that is less than 3 mm in thickness, but when such tank is to be used for gasoline and has a capacity exceeding 23 L and is made of material of less than 3 mm in thickness that is not corrosion resistant, it shall be galvanized inside and outside by the hot-dipped process after construction is completed; (g) mass produced cylindrical gasoline drums having a capacity exceeding 23 L and not exceeding 227 L may be used as fuel tanks without alteration if they (i) have been galvanized inside and out and are c
