GTA is just one part of the approximately 13,500km2 of acreage held by bp and its partners in Mauritania and Senegal, thought to contain between 50-100tcf of gas resource potential. GTA alone is estimated to contain more than 15tcf of potentially recoverable gas resources.
bp is committed to helping both countries to develop their world-class resources in a sustainable way.
In December 2018, bp announced the Final Investment Decision (FID) for Phase 1 of the innovative cross-border Greater Tortue Ahmeyim development, following agreement reached between the Mauritanian and Senegalese governments and partners bp, Kosmos Energy and National Oil Companies Société des Pétroles du Sénégal (PETROSEN) and Société Mauritanienne Des Hydrocarbures (SMH).
This marked the beginning of a multi-phase project that is expected to have a lasting and positive impact for generations to come.
Gas will be produced from an deep-water subsea production system and processed in the mid-water by a floating production, storage and offloading (FPSO) vessel. The FPSO was built in China and travelled over 12,000 nautical miles to the GTA field.
The FPSO will process the gas, removing water and impurities prior to liquefaction.
The gas will then be sent ~35km through a pipeline to the inshore Hub/Terminal, which includes a breakwater providing shelter to a floating liquefied natural gas (FLNG) facility.
As part of the liquefaction process, gas will be cooled to temperatures below 162ºC in order to transform it into a liquid which enables storage and long-distance transportation.
Liquefied Natural Gas (LNG) from GTA will be exported via LNG carriers which will berth at the Hub Terminal before being transferred to LNG carriers for export. Some of the gas will be allocated to help meet growing energy demand in the two host countries.
Once fully commissioned, GTA Phase 1 is expected to produce around 2.3 million tonnes of LNG per year.
