Marine and offshore environments combine salt spray, humidity, and temperature cycling—ideal conditions for corrosion. Corrosion protection typically includes multi-layer coating systems (zinc-rich primer + epoxy + polyurethane topcoat), stainless or plated fasteners, sealed bearings, and improved gasket and seal designs. For hydraulic components, corrosion-resistant cylinder rods and properly protected fittings are critical.
Material selection matters: using compatible metals reduces galvanic corrosion, especially when stainless parts contact carbon steel. Drainage and ventilation are also important—trapped water accelerates rust. In addition, specify an appropriate IP rating for electrical components and consider conformal coating for PCB-based power supplies.
For brakes on winches, cranes, and wind turbines offshore, also consider friction surface management: rust buildup can change friction behavior and cause uneven wear. Routine washing, inspection, and lubricant practices are part of corrosion control. A “marine package” should be defined clearly in your specification so the supplier can apply the correct coating thickness, surface preparation standard, and hardware upgrades.
