HongHua Offshore completes design for LNG Production Platform

HongHua Offshore has announced that it has completed the basic design for their Proto-type LNG Production Platform (PLNG).

The LNG Production Platform development has spanned several years, requiring an investment of over US$30 million. Although financed and led by HongHua, this project has required the combined effort of HongHua Infrastructure Partners (HHIP), along with several leading engineering companies.

HHIP is made up of HongHua Offshore, China Aerospace (CASC), Braemar Technical Services, and EnTX GasTek (Global) Ltd. HHIP is in turn supported by the likes of Wood Group, GE Oil & Gas, ABS, Bureau Veritas, and ARUP.

The Proto-type design was completed in conjunction with a PreFEED Study conducted by Wood Group with the participation of Braemar Technical Services and GE Oil & Gas in respect to a project anticipated to be located offshore in the West Delta area of the US Gulf of Mexico. ABS has granted an Approval in Principal for this project design. Other projects are under consideration in the GoM, Latin America, Southeast Asia, and Africa.

The PLNG facility is comprised of a number of different fixed offshore platforms joined to form a unit for the production, storage and shipment of LNG. The facility is designed to withstand weather conditions on the US Gulf of Mexico shelf but can be adjusted to most offshore conditions in water depths up to 100 m. The main components are GE liquefaction trains powered by marinized GE LM2500 gas turbines, aluminium FSP storage tanks, and marine loading facilities. 

GE Oil & Gas has designed the liquefaction trains as well as the power platform which supplies electric power to the LNG pumps, marine facilities, and accommodations. 

The FSP storage tanks were developed by TankTek, Ltd, a HongHua subsidiary, in conjunction with Braemar Technical Services (under license from the Nassco division of General Dynamics), EnTX Tekmar, and Jamestown Metal Marine. The unique flat-panel, prismatic shape of the tanks allows for maximum storage to space ratio, as well as provides a low-profile design suitable for offshore weather conditions. The light weight of the tanks allows them to be fixed to the jacket in the yard and transported by heavy lift vessel directly to the site where they are “floated over” the fixed pilings for installation.
