- (a) Each unmanned deepwater port located north of 32 degrees North latitude must comply with the immersion suit requirements applicable to mobile offshore drilling units under [46 CFR 108.580](/cfr/46/108.580.md), and immersion suits must be approved under approval series 160.171. Except as under [paragraph (b)](#b) of this section, the immersion suits need be on the deepwater port only when persons are on board.
