§170.200. Estimated lightweight vertical center of gravity.
46 C.F.R. § 170.200
Each tank vessel that does not carry a material listed in either Table 1 of part 153 or Table 4 of part 154 of this chapter may comply with this section in lieu of § 170.175 if it—
Is 150 gross tons or greater;
Is of ordinary proportions and form;
Has a flush weather deck, one or more longitudinal bulkheads, and no independent tanks; and
Is designed not to carry cargo above the freeboard deck.
When doing the calculations required by §§ 170.170 and 172.065, the vertical center of gravity of a tank vessel in the lightweight condition must be assumed to be equal to the following percentage of the molded depth of the vessel measured from the keel amidship:
For a tank ship— 70%.
For a tank barge— 60%.
As used in this section, molded depth has the same meaning that is provided for the term in § 42.13-15(e) of this chapter.
