Modular design

Flexible operation

capable of handling a range of field gas compositions

The floating LNG facility was designed to produce in excess of 1.7 million tonnes of LNG per annum, processing a range of feed gas compositions. The topside facilities are modular in design and consist of a field specific section, conditioning the incoming gas to a specification suitable for processing in a generic section. The generic section incorporates a gas pre-treatment plant for the removal of carbon dioxide, water and mercury, and a two-train liquefaction system. The generic section has the potential to be replicated on further LNG Producer vessels.

Costain was awarded the contract to continue providing engineering services through to detailed design and package management, bringing extensive cryogenic experience in gas processing and LNG to the project.
