Heerema Marine Contractors’ Deepwater Construction Vessel Balder

Following Total E&P Angola’s $16 billion final investment decision on Monday, Technip and Heerema Marine Contractors have been awarded the largest SURF (subsea, umbilical, riser, flowline) contract ever to develop 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 ± 55% and a Heerema share of ± 45%.

Pieter Heerema, Chairman and Owner of Heerema Marine Contractors, commented on the award:

“To be awarded the largest SURF project in the industry to date as the first project for the Technip Heerema Alliance is a fantastic success. This award is a recognition that our clients appreciate the value of the Alliance in delivering safe, robust, competitive and unrivalled solutions for large and complex ultra-deepwater projects. Building on our reputations, we are convinced that we will bring this prestigious project to a successful end. Finally, we are very pleased that the award of the Kaombo project allows us to bring substantial work volumes to our Angolan fabrication and marine transportation companies.”

Scope of work

Engineering, procurement, fabrication, transport and installation of:

  • 18 rigid risers, of the Single Top Tension Riser (STTRs) 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.

Transport and installation of:

  • approximately 115 km of client-supplied umbilicals, manifolds, well jumpers and flying leads.

Heerema will be responsible for the riser systems, as well as the deeper and heavier pipe-in-pipe (18”/12”) production pipelines, while Technip handles the flowlines, flexible pipe manufacturing and installation, umbilical installation, hook-up and pre-commissioning activities.

Most of the offshore installation activities are scheduled for 2016 and 2017.

Heerema notes they plan to mobilize the Deep Water Construction vessel 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.
