Tullow Ghana Limited has completed the Interim Spread Mooring of the Jubilee FPSO, Kwame Nkrumah.
This milestone involving the installation of an interim anchoring system on the stern of the FPSO to hold the vessel in place, completes the first phase in the Turret Remediation Project which will eventually provide the FPSO with a long-term mooring solution.
In addition to the existing anchor lines on the FPSO’s turret, the FPSO is now firmly secured in position by six anchor lines, three on each side of the stern of the vessel allowing the three tug boats which have been keeping the FPSO in place over the last 11 months to return to shore.
This phase of the project has been achieved with production maintained at optimal levels with the exception of short, planned reductions for technical reasons. Oil and gas offtakes have also continued in the new normal state of operations.
The JV partners are now analysing options for the next phase of the project which will involve modifications to the turret systems for long-term operations.
Detailed planning for these works continues with the JV Partners and the Government of Ghana, with final decisions and approvals being sought in the first half of 2017 and work expected to be carried out in the second half of 2017.
Charles Darku, Managing Director of Tullow Ghana Ltd commented “It is a highly complex and significant achievement for an FPSO to be held to one heading by tugs within a few degrees for 12 months and for production to have been maintained throughout. We would like to recognise the strong collaboration with our Joint Venture Partners, the Government of Ghana and our key contractors in achieving this important milestone.”
