The consortium was responsible for engineering, supply, construction, offshore commissioning and procurement of the vessel. Technip was the project manager and was also responsible for the initial engineering phase. HHI was responsible for the construction of the hull and also the construction and integration of the topside modules. Some of the engineering tasks fabrication of components was carried out when the vessel reached Nigeria.

The Akpo floating production storage and offloading vessel FPSO was commissioned in mid by Total Upstream Nigeria following the successful development of the Akpo oil and gas field, km south of Port Harcourt off the coast of Nigeria in West Africa.
The consortium was responsible for engineering, supply, construction, offshore commissioning and procurement of the vessel. HHI was responsible for the construction of the hull and also the construction and integration of the topside modules. Some of the engineering tasks fabrication of components was carried out when the vessel reached Nigeria. Construction The vessel is m long, 61m wide and has facilities to accommodate crew members.
The topside fabrication and fitting out was completed in December and the vessel began operations at OML , approximately km south of Port Harcourt,Nigeria in March The Akpo hull has a storage capacity for two million barrels of oil and the deck was designed to accommodate 17 topside modules, which includes two processing trains for the separation of oil and water. These were installed to provide electrical power for the FPSO vessel. The six RB gensets are capable of providing the MW of electrical power needed to operate the subsea components of the field.
The subsea set up includes 22 oil and gas production wells, 20 water injection wells and two gas injection wells. HHI contracted Nexans to install 1,km of offshore cables for power and instrumentation infrastructure. In addition, Total awarded a contract to Saipem to supply of all the umbilicals, flowlines and risers for the vessel under a turnkey basis. The contract also includes EPC engineering, procurement, construction, installation and commissioning of the oil loading terminal, the FPSO mooring system and the gas export pipeline from the FPSO to the Amenam platform.
In April , Cameron was contracted to provide the subsea production system including the supply of Christmas trees, manifolds, connection systems, control systems and engineering. The main automation contractor for the FPSO is Emerson Process Management who provides digital automation architecture to digitally integrate the topside module control systems.
