The US Coast Guard posted guidance on the inspection, repair, and maintenance of liftboats. As the guidance points out, for many purposes, liftboats are treated by the Coast Guard like conventional hulled offshore supply vessels (OSVs). In certain aspects, though, liftboats are unique. The guidance provides liftboat-specific information relating to automation, steel wastage, tail shaft inspection intervals, drydock inspections, lifesaving systems, fire fighting equipment, systems/equipment for general operation, crane inspection, and manning.
