For the purposes of this chapter a “marinised” crane should be understood to mean it is a type originally designed for use ashore, typically lorry mounted, that has been modified to better withstand the rigours of the marine environment. It will have been subject to a marine paint scheme and the hydraulic cylinder rams will either be manufactured of stainless steel, or of mild steel with multiple chrome coatings to reduce the risk of corrosion. In addition the crane will either have been de-rated by a significant amount, typically 30% to take account of the dynamic loading effect of being vessel mounted, or the vessel will be supplied with load charts, based on harbour conditions.
