2017: FPSO Nkrumah To Go On A 12 Week Shutdown Over Bearing Fault

Information gathered by News Ghana indicated that, FPSO Kwame Nkrumah, which operates in the Jubilee Fields of Ghana, will again be shut down for between eight and 12 weeks in 2017.

This is to allow Tullow Oil PLC and its partners explore measures to find a permanent solution to the vessel’s turret bearing fault.

Tullow has stated in its recent update that, an issue with the turret bearing of the FPSO Kwame Nkrumah, identified in February 2016 has resulted in the need to implement new operating and offtake procedures, which called for the shutting down of the facility for an extended period in April with production resuming in early May.

Tullow said it expects to continue operating the field under these new procedures for the remainder of 2016 and anticipates average gross production to be around 85,000 bopd in the second half of 2016 and that it had made progress together with its partners towards establishing the “best long-term solution and, based on the work undertaken over the past four months, now see converting the FPSO to a permanently spread-moored facility, with offtake through a new deepwater offloading buoy, as the preferred long-term solution”.

It also indicated that, the partners are working with the Government of Ghana to seek their approval for this option. “The first phase of this work will involve the installation of a stern anchoring system to replace the three heading control tugs currently in the field. This is anticipated to be completed by the end of 2016 and will require short periods of reduced production.

“Tullow then plans a second phase of work to rotate the FPSO to its optimal spread moor heading in the first half of 2017. The work programme covering these phases, which requires Government approval, is expected to cost $100-150 million gross and it is estimated that the Jubilee FPSO will need to be shut-down for 8-12 weeks during the first half of 2017,” the update added.

Tullow said upon completion of the spread mooring work programme in mid-2017, the partners will review opportunities to improve the efficiency of offtake procedures, which may include the use of a larger dynamically-positioned shuttle tanker, and seek to return production to levels seen before the turret issue occurred.

Tullow indicated that a deep water offloading buoy is anticipated to be installed in the first half of 2018 that will remove the need for the dynamically positioned shuttle and storage tankers and the associated operating costs.
