LONDON — The FPSO for the Greater Tortue Ahmeyim LNG development, 40 km offshore Mauritania and Senegal, has departed Qidong, China.

It follows a series of sea trials after completion of the 3.5-year construction program. The vessel will sail 12,000 nautical miles to the offshore location via Singapore.

The bp-operated project includes subsea development of gas fields and near-shore floating LNG (FLNG) facilities. The company expects to produce about 2.3 MM metric tons per year of LNG under the current first phase.

The FPSO, with eight processing/production modules, will process 500 Mcf/d of gas, removing condensate, water and impurities before exporting it to the FLNG unit 10 km offshore. Much of the incoming gas will be liquefied by the FLNG facilities for export to international markets, with the remainder allocated to support domestic needs in the two host countries.

Periodically, the condensate will be offloaded from the FPSO to shuttle tankers for export.

The FPSO, located in 120 m of water, will house up to 140 people on board during normal operation and serve as a base for the project’s production team. It comprises more than 81,000 metric tons of steel, 37,000 m of pipe spools and 1.52 million m of cable.

Last October bp signed an E&P sharing contract for the BirAllah gas field offshore Mauritania, and more recently, it inked a memorandum of understanding with Mauritania’s government to investigate the potential for large-scale production of green hydrogen in-country.

In addition, bp and its partners are working on a gas-to-power project in Senegal that would be supplied from the offshore Yakaar Teranga Field.
