TechnipFMC wins $1 billion Brazil subsea contract for Equinor

TechnipFMC has signed a letter of intent with Equinor Energy do Brazil Ltda., a subsidiary of Equinor ASA, for an integrated FEED (iFEED) study on its BM-C-33 project offshore Brazil.

The study will finalize the technical solution for the proposed gas and condensate greenfield development in the presalt Campos Basin before Equinor makes its final investment decision (FID).

The FEED study includes an option to proceed with a direct award to TechnipFMC for the integrated engineering, procurement, construction and installation (iEPCI) phase of the project.

The major iEPCI contract, which TechnipFMC defines as more than $1 billion, would cover the entire subsea system, including Subsea 2.0 tree systems, manifolds, jumpers, rigid risers and flowlines, umbilicals, pipeline end terminations, and subsea distribution and topside control equipment. TechnipFMC would also be responsible for life-of-field services.

Vår safeguards subsea deliveries for offshore Norway projects

Vår Energi has formed a strategic partnership covering delivery of subsea equipment for all its operated projects in Norway with Aker Solutions, Havfram and Saipem, according to June 30 press release.

CEO Torger Rød said the new model should lead to reduced costs and improved efficiency and predictability in delivery. The contracts run for five years with options for tow-year extensions, up to nine years in total.

Vår describes the arrangement as built on a “one-for-all and all-for-one principle and contrasts with the conventional model of separate contracts with split scope and responsibilities."

“Strategic partnering and early involvement of the suppliers secure more efficient planning and implementation of projects," said Annethe Gjerde, vice president of contracts and procurement. “A strong partnership will provide added value for all parties, which we also see as part of the standardized supply chain behavior guideline developed by a joint industry effort facilitated by the Norwegian Oil and Gas Association.”

The company presently produces close to 250,000 boe/d from its shares of 36 fields and is targeting 350,000 boe/d by 2025.

Aker Solutions’ scope covers the full range of equipment and services for subsea production systems and FEED/design work for the upcoming field developments.

XLCC cleared to construct subsea cable plant in Scotland

North Ayrshire Council Planning Committee granted planning permission for XLCC’s HVDC subsea cable manufacturing operations in late Junein Hunterston, western Scotland.

Construction on the brownfield site is due to start in the next few months. XLCC's first order is for four 3,800-km long cables to connect solar and wind renewable power generation in the Sahara to the U.K. through the Xlinks Morocco-UK power project.

XLCC also is investing in a cable lay vessel, designed to manage all aspects of cable handling, from protecting the quality and integrity of the cable during delivery from the factory through installation on the seabed.

The vessel will have the capability to deploy cables individually or in a bundled pair configuration. XLCC will also provide services including high-pressure trenching, mechanical cutting and rock placement after the cable has been laid on the seafloor, using a separate, dedicated vessel.

It has further plans to offer cable repairs in the event of a cable failure or during periods of preventative maintenance.
