Technip has won a brownfield and subsea tiebacks contract for Total’s deepwater Moho Nord project offshore West Africa’s Republic of Congo, its second contract for the development.

The French contractor was awarded the engineering, procurement and supply contract by Total E&P Congo for the Moho Phase 1bis project, with the workscope to include:

• Addition of a first stage separator, a valves manifold, an essential diesel generator, an additional control room, topsides umbilical termination units
• Replacement of methanol and dead oil pumps
• Extension and upgrade of the integrated control and safety system
• Integration studies of equipment provided by other contractors.

The Moho Nord development is located 75 km offshore Pointe Noire and consists of two developments: Moho Phase 1bis and Moho Nord, which lie in water depths ranging from 650-1,100 m (2,133-3,609 ft). This latest contract is part of the Moho Phase 1bis development, said Technip.

It is a brownfield development consisting of tiebacks to the existing deepwater Alima Floating Production Unit (FPU) and the shallow-water N’Kossa platform. The contract covers the project management, detail engineering, procurement and supply for the modifications of the Alima FPU, with two new sub-sea tiebacks.

Technip’s operating center in Paris will manage the contract, which is scheduled to be completed in the first semester of 2015. The company will also provide assistance to Total for the off- shore construction phase to be spread from 2014 to 2016, it added in the release.

In April Technip won a major lump-sum contract for the engineering, procurement, supply, construction, installation (EPSCI) and pre- commissioning for the Moho Nord development (see DI, 22 April 2013, page 8). Moho Nord will be tied back to a newbuild FPU and a new- build Tension Leg Platform (TLP).

That contract was much larger, covering the project management, engineering, supply, fabrication and installation of:
• 230 km of rigid pipelines,
• 23 km of flexible pipes,
• 50 km of umbilicals,
• 50 subsea structures as well as various other structures and rigid jumpers.

It also included the installation of client-supplied manifolds and pumps, control system components and multiphase jumpers.
