HOUSTON – VAALCO Energy has contracted DOF Subsea for subsea construction and installation services for the Etame field offshore Gabon.
These will support the subsea reconfiguration associated with replacement of the field’s existing FPSO with a converted Floating Storage and Offloading (FSO) vessel. The Cap Diamant entered a shipyard in Bahrain last month for the conversion process.
DOF Subsea will supply personnel and equipment necessary to help reconfigure production to the FSO. Engineering and design have been completed for the field infrastructure upgrade: subsea work should start in July and be completed before the FSO starts operating in September 2022, as previously disclosed.
The scope includes use of a DOF Subsea offshore construction vessel to perform the work; transporting over 5,000 m (16,404 ft) of new flexible pipelines from the UK to install in the field; undertaking retrieval and relocation of in-field flowlines and umbilicals; and supporting connection of new risers to the FSO.
George Maxwell, VAALCO’s CEO, said that the FSO should increase storage capacity at Etame by over 50% and cut costs by almost 50% compared to the current FPSO.
