Marine and offshore hydraulic cylinders face an operating environment that no standard industrial cylinder specification can handle \u2014 continuous salt spray corrosion, fire safety regulations mandating non-mineral hydraulic fluids, and the certification requirements of classification societies that mandate documented proof of structural integrity for every safety-critical component. A standard lift cylinder specified for industrial service will typically last 6\u201318 months in a marine environment before corrosion destroys the rod surface and seal integrity. This guide covers the engineering disciplines that govern offshore and marine cylinder specification.<\/p>\n
