Angolan contractor Sonamet has completed factory acceptance tests on all flowline structures for the next stage of work on the Zinia field.
Sonamet, working with Subsea 7, said the work had been completed despite the challenges thrown up by the state of emergency in Angola. It has fulfilled stringent performance requirements, the company said.
This milestone demonstrates robust engineering, management of suppliers, collaboration, fabrication experience and resilience, Sonamet said.
Total is carrying out Zinia Phase 2 under its Project Brown Field (PBF). This also includes Dalia Phase 3 and CLOV Phase 2.
Total took final investment decision (FID) on the Zinia work in 2018. The company said this would cost $1.2 billion and add 40,000 barrels per day of production. Output will go to the Pazflor floating production, storage and offloading (FPSO) unit.
Sonamet has previously reported the first steel cut for the Zinia work on February 22, 2019.
The yard won work on Dalia Phase 3 in May 2019. Aker Solutions and Total E&P Angola awarded the work to Sonamet, covering a manifold, associated foundations, levelling frame and four submarine umbilical terminals.
The contractor expected the Dalia work to end in the fourth quarter of 2020. This would then allow installation, and production, in early 2021.
On winning the Dalia contract, Sonamet said it would use experience gained from its work on the Kaombo contract. It also expected there to be synergies between the Dalia and Zinia work.
Subsea 7 has a 55% stake in Sonamet, while Sonangol has 40% and Wapo 5%. Sonangol has said it is working on plans to sell off its stake in Sonamet.
