Regulation 8 Segregated ballast oil tankers

Where segregated ballast tanks complying with Regulation 13 of Annex 1 of the International Convention for the Prevention of Pollution from Ships 1973^f1, as modified by the Protocol of 1978^f2 relating to that Convention, are provided in oil tankers, an entry may be made on the International Tonnage Certificate (1969) indicating the total tonnage of these tanks. The tonnage of such segregated ballast shall be calculated according to the following formula—

$${\mathrm{K}}_1\times {\mathrm{V}}_{\mathrm{b}}$$

where—

K₁

0.2 + 0.02 log₁₀ V, as specified in Schedule 2;

V

the total volume of all enclosed spaces of the ship in cubic metres; and

V_b

the total volume of segregated ballast tanks in cubic metres measured in accordance with regulation 5.
