Lifting appliances on board ship, particularly ship’s cranes, are critical to a vessel earning freight. A ship is only earning money, ie, freight, when carrying cargo at sea.

For this reason, and the safety of the crew, ship’s cranes should be well maintained, usually whilst at sea, to reduce the possibility of port downtime.

This volume of the Oilfield Seamanship Series illustrates how jackup rigs are safely moved from one location to another in an offshore environment. The purpose of the book is to support tow Masters, personnel responsible for moving jackup rigs, tug and anchoring handling vessel crews, and those ashore involved in planning rig move operations.
