Project Profile
Value: Undisclosed
Location: Block 4/05, 85km off the Angola coast
Start-up Year: April 2009
Reserves: 50 million barrels of oil equivalent
Water Depth: 700m (2,296ft)
The Gimboa field is located 53 miles (85 kilometers) offshore Angola, Africa, on Block 4/05 at a water depth of 2,297 feet (700 meters).
Technip was awarded the contract, worth approximately US$70m, for the engineering, procurement, fabrication, testing, installation and pre-commissioning of one production flowline, one water injection flexible flowline, one gas lift flexible pipe, one service umbilical, an associated flexible risers system and flexible well jumpers. The engineering was carried out with the assistance of its operations and engineering centre in Luanda, while the company\'s umbilical plant, Angoflex, manufactured the umbilical and provided logistic support. The flexible lines were manufactured by Flexi France in Le Trait (France). This contract also included the installation of other subsea equipment, provided by Sonangol P&P. Offshore operations were performed using a dynamically positioned vessel in 2008.
Gimboa field contractors:
Saipem subcontracted the fabrication company Lamprell to build six topside process modules in a US$30.3m deal. In addition to the main contract, this included an option for the fabrication of the piperack worth another US$8.7m. These modules are for lift and flash gas compression, high and low-pressure separation, plus a chemical injection skid, a processing manifold and an equipment room. VWS Westgarth supplied the sulphate removal package. Its scope consists of a water injection plant in a single lift module arrangement comprising of: seawater coarse strainers, a chlorination unit, dual media fine filtration, guard cartridge filters, HP feed pumps, a sulphate removal membrane system, a fresh water membrane system, a vacuum deaerator, water injection pumps, a chemical cleaning system, chemical dosing systems, control valves and instrumentation, fresh water distribution systems, module lighting, fire and gas detection and fire-fighting systems.
