Under the terms of the agreement, KBR’s and Granherne’s expertise in field development planning, concept evaluation and FEED will be combined with Subsea 7’s subsea project management and engineering experience and the application of technology and know-how in order to enable improved cost-benefit evaluation and ensure a greater contribution at the early stage of projects.

The two firms plan to provide cost-effective services to oil and gas companies during the concept evaluation phase of field developments.

The deal, which will be on a project-by-project basis, will have provision for collaboration of KBR and Subsea 7 in the execution phase of offshore projects.

Subsea 7 CEO Jean Cahuzac said: "I look forward to strengthening our relationship with KBR through this alliance which provides the opportunity for early engagement in the project lifecycle when value creation can be optimised and where we can introduce enabling subsea technologies and know-how at the critical concept evaluation stage.

"This is key to assisting the offshore oil and gas industry to adapt to the lower oil price environment."
