You need to know that a chief engineer must keep a logbook for the engine room. The chief engineer is in charge of the engine room on a ship. They have to write down important information in the logbook. You can find more information about this rule in the Maritime Transport Act 1994, but this specific rule was repealed on 2 February 1998. This means it is no longer a rule that chief engineers have to follow. The rule was repealed by section 187.
