Offshore Gas Liquification Plant, Djibouti

Poly-GCL will explore and produce natural gas in a total area of 117,151 km2 in Ogaden Basin, Ethiopia. Natural gas pipeline will be built to transmit the natural gas from gas development area in Ethiopia to Djibouti, where a LNG liquefaction plant is to be constructed. The Djibouti LNG Plant Project will be located at the seaside, 10 km south east to the Djibouti city of the Republic of Djibouti. Gravity-based technology will be used.

The initial phase of the project is to build a LNG production plant with capacity of about 3MTPA, and reserve a provision (land and tie-in points) for future expansion (Phase II and Phase III), to reach a total (all three phases) LNG productivity of 10MTPA.

The LNG plant includes all process units, LNG transmission system, utilities and auxiliary facilities, including seawater desalination system, production and administration buildings, power station and firefighting facilities, etc.

HalcrowSea has provided independent design review and technical assessment on FEED/POST-FEED of onshore and nearshore LNG plant, made comparison study, key process simulation analysis, economics analysis, CAPEX & OPEX analysis etc. Also we provided other related owner's engineer services.

Also FEED for marine works was carried out included navigation routes selection, navigation channel design, overall layout design, tug design, mooring arrangement, jetty design, trestle design, causeway design, 2D navigation study, cost estimates, construction schedule, related specifications.
