Kosmos Energy has wrapped up a deal covering the sale and leaseback of a floating production, storage and offloading vessel that forms a key part of BP’s Greater Tortue Ahmeyim (GTA) gas project off Senegal and Mauritania.

This transaction allows the Dallas-based independent to secure additional funding for phase one of the project. It reported last month that costs had ballooned by 15% to about $4.6 billion and first gas has slipped from the first half of 2023 to the third quarter.
