Yes, Most ocean going ships have a lathe and drill etc just in case .On container ships you have lots of winches,electric motors,pumps and so on ,and if trouble should strike and you are mid pacific it is up to the ships engineers to remake any parts required. Burt Munro, the man immortilised in the movie,the Worlds fastest indian ,spoke of getting a job as cook on a freighter so he could use the ships machine shop to make pistons and other parts as he sailed to the US from New Zealand.
