OSHA and commercial vessels

I was under the impression that OSHA had no authority on commercial vessels because the USCG retained sole authority over work rules and such but a captain I work with swears that OSHA does have authority on boats. So whats the deal?

Your captain is correct.

“On January 9, 2002, in Chao v Mallard Bay Drilling, the Supreme Court held that OSHA does have jurisdiction over uninspected vessels, putting the issue to rest at last.”

From a maritime consulting website.

But only on uninspected vessels? If you have a COI OSHA has no jurisdiction?

Here is a link to probably more information than you ever wanted to know on this issue:

OSHA only has jurisdiction while in a US Shipyard for inspected Vessels. Shipmate 1
