Abstract:

This report presents the computation procedure that is used to produce load rating charts for cranes operating on platforms in the ocean environment. A rating charge defines the load that can be safely lifted for each boom angle in the boom operating range. The platform supporting the crane may be a fixed offshore platform or a ship or barge. During the crane operating cycle, loads will be lifted from or placed on a work boat or some other small vessel. The procedures utilizes the relative motion of the supporting platform and the vessel alongside to determine dynamic load factors. The dynamic load factors are applied to the land rating to derate the crane for marine operations. The computation procedure has been implemented in a computer program that is also discussed.
