Nitrogen membrane system for LNG-powered vessels


Norwegian firm to supply nitrogen membrane generators for six LNG-fuelled Platform Supply Vessels.



Norway-based Air Products has been selected by Harvey Gulf International Marine to supply nitrogen membrane generators for the six newly ordered LNG-fuelled Platform Supply Vessels (PSV) to be built at Trinity Offshore Shipyard, Gulfport, Mississippi.

The NC 1.1 series cabinet model consists of a complete N2 Generator, a control panel and a feed air pre-treatment with a PLC control. The nitrogen membrane system is said to have been approved by "all international marine standards". According to Air Products, the fact that the system is DNV type approved was one key reason for Harvey Gulf International to select this system.

"This unique nitrogen membrane generator has a reduced footprint and lowers the operational cost at the same time. Maintenance is kept to a minimum thanks to the robust design and carefully selected materials, which meet the stringent operational demands for Platform Supply Vessels. The Standard Serial Line Communication (Modbus) can be connected directly into the vessel’s IAS (Integrated Alarm System)," Air Products said.
