Technip Heerema alliance wins subsea contract offshore Angola The consortium, comprising Technip and Heerema Marine Contractors (Heerema), was awarded a major lump-sum contract by Total E&P Angola for the engineering, procurement, construction, installation (EPCI) and pre-commissioning for the SURF (subsea umbilicals, risers and flowlines) part of the Kaombo project, located in Block 32 offshore Angola in water depths up to 2,000 meters. The contract is valued at approximately USD 3.5 billion with a Technip share of around 55% and a Heerema share of around 45%.

This project falls within the Technip Heerema strategic alliance formed 15 months ago that offers comprehensive subsea solutions through a unique combination of complementary assets, technologies and capabilities. It provides the industry with a strong and experienced contractor to address the ultra-deepwater market.

The project’s scope of work consists of the engineering, procurement, fabrication, transport and installation of:
    - 18 rigid risers, of the Single Top Tension Riser (STTR) type, including large buoyancy tanks (~40m high, ~6m diameter), flexible top riser jumpers and riser base spools,
    - approximately 300 kilometers (km) of rigid pipe-in-pipe production and single pipe injection pipelines,
    - a large number of subsea structures, piles and steel jumpers.

Besides, it covers the transport and installation of approximately 115km of client-supplied umbilicals, manifolds, well jumpers and flying leads.

The partners will leverage the complementarity of their respective field-proven technologies, thus optimizing the project execution:
    - Heerema’s scope will cover the riser systems, as well as the deeper and heavier pipe-in-pipe (18”/12”) production pipelines,
    - Technip’s scope will include flowlines, flexible pipe manufacturing and installation, umbilical installation, hook-up and pre-commissioning activities

The engineering work will start immediately in the Paris (France), Leiden (the Netherlands) and Luanda (Angola) centers with most of the offshore installation activities being scheduled for 2016 and 2017.

National content is of strategic importance to Technip and Heerema and their Angolan subsidiaries will bring their competencies and expertise to the project. Technip Angola Engenharia will provide engineering and project management services, while Angoflex will fabricate pipeline stalks and execute spooling services to the installation vessel. Heerema Porto Amboim will provide fabrication services for the subsea structures as well as double jointing of line pipe sections that later will be installed by the Deep Water Construction vessel Balder.

The flexible pipes will be manufactured at Technip's FlexiFrance facility in Le Trait (France). The fabrication of the rigid flowlines for reel lay will take place at Angoflex’s spoolbase in Barra do Dande (Angola).

Heerema intends to mobilize its Deep Water Construction vessel, the Balder, to install all STTRs and the pipe-in-pipe (18”/12”) production pipelines. Technip’s vessel, the Deep Blue, will install all the remaining pipelines. Other vessels from Technip's fleet will install the flexibles and umbilicals and provide construction work support.

The project is scheduled for completion in the first half of 2018.
