Both are destined for theAnyala and Madu fields in Oil Mining Leases 83 and 85 offshore Nigeria, in the Niger Delta basin. The planned development will recover around 185 MMbbl of oil and 637 bcf of gas.
Aquaterra Energy will manage the project with engineering and onsite fabrication support performed in Nigeria.
The work scope includes structural design, topsides engineering, equipment selection, procurement, fabrication management and logistics.
On completion, the platforms (which are different designs) will be installed in water depths of 35-55 m (115-180 ft). First oil should flow in late 2019.
Aquaterra Energy describes its Sea Swift design as a modular system that combines an offshore platform with the rig-run benefits of a subsea development. This is said to give operators flexibility that allows them to cut construction and installation costs, and reduce time to first oil in shallow-water fields.
