Two of Technip’s deepwater construction vessels, the G1200 (Technip BV), a rigid pipe S-lay and heavy-lift construction vessel, and the Deep Pioneer (Technip UK), a multipurpose deepwater vessel, have been contracted by Total to carry out a major subsea installation project at the Moho Nord development off the coast of the Congo between 2014 and 2016. The project is located in water depths ranging from 650 to 1,100 meters, and consists of the project management, engineering, supply, fabrication and installation of:
•230 kilometers of rigid pipelines,
•23 kilometers of flexible pipes,
•50 kilometers of umbilicals,
•50 subsea structures as well as various other structures and rigid jumpers.
It also includes the installation of client-supplied manifolds and pumps, control system components and multiphase jumpers.
Technip notes that this is the largest full scope subsea contract that they have ever taken on, but didn’t put a pricetag on it.
This project consists of two developments, the Moho Phase 1bis and Moho Nord, with first oils being respectively expected in 2015 and 2016. The Moho Nord development, which will be tied back to a new floating production unit (FPU) and a newbuild tension-leg platform (TLP), includes an oil export line to the Djeno onshore terminal and will also be tied back to the shallow-water N’Kossa platform for gas exchange. The Moho Phase 1Bis development consists of tie-backs to the existing deepwater Alima FPU.
Technip’s operating center in Paris, France will carry out the overall project management and engineering of this fast-track and multi-disciplinary subsea project. The flexible pipes will be fabricated at Flexi France, Technip’s manufacturing plant in Le Trait, France and the umbilicals will be fabricated at the Group’s new manufacturing unit in Newcastle, United Kingdom. As part of the project, Technip will engage with Pointe-Noire-based contractors to fabricate various steel structures in Congo.
