Subsea 7 has won an engineering, procurement, construction and installation (EPCI) contract in Ghana from Tullow Oil, for work on the Jubilee field’s FPSO. Announcing the work on October 10, Subsea 7 said this was a “sizeable” contract, which it defines as worth US$50-150 million.
The contractor will do the work with NOV Oil & Gas Services Ghana, it said.
Work will cover the installation of a buoy turret loading (BTL) system from APL, which is part of NOV. In association with this there will be suction piles and work on two offloading lines, for the BTL, and an additional hang-off platform and skid for the FPSO.
Subsea 7 said a “significant part” of the fabrication work would be carried out in Ghana and installation would occur in 2020. Initially, the partners on Jubilee had hoped to install a catenary anchor leg mooring (CALM) buoy in 2019.
Kosmos Energy posted an operational update on October 10. The US-listed company said production from Jubilee had averaged 94,500 bpd during the most recent quarter. One new production well had come online in the third quarter, with another expected in the fourth quarter. These new wells, coupled with improvements in the vessel’s gas handling capacity, should allow output to increase “towards” its full capacity, of 120,000 bpd.
The TEN project produced 62,600 bpd during the quarter, with one new well starting in August. This should allow production to increase to 70,000 bpd by the end of 2018. The FPSO on the TEN field has been tested above its 80,000 bpd nameplate capacity and Kosmos said it expected to test this limit in 2019 with new wells starting up.
A second rig, the Stena Forth, arrived in Ghana in September. The goal, Kosmos said, is to maintain gross production from the two FPSOs at 180,000-200,000 bpd over the next three years.
