Above decks

Various motion systems are installed above deck: for management of gangways and floating platforms on yachts, control of winches and lifting arms on FPSO ships, and opening and closing of process valves.

The installation environment means that systems are exposed to bad weather, with a saline atmosphere and potentially direct contact with salt water. Therefore, the protective surface treatments are fundamental to avoid oxidation, maintaining the functionality of components and their aesthetic properties.

Duplomatic has developed protective surface treatments that avoid use of stainless steel in most cases, guaranteeing more competitive solutions.
