Subsea 7 has been awarded a contract to provide diving support vessel (DSV) services in the UK offshore area for six North Sea clients.
The three-year agreement with four one-year options has been awarded by Chevron North Sea, Dana Petroleum, Hess Denmark, Nexen Petroleum, Talisman Sinopec Energy and TAQA Bratani.
The latest agreement is an extension of a previous signed agreement in 2009.
Subsea 7 said it will continue to provide DSV services, as well as associated project management and engineering services to more than 40 facilities in the North Sea.
The collaboration will allow all operators to benefit from lower costs from sharing of resources.
Under the agreement, the company will provide diver and ROV inspection, repair and maintenance, subsea construction and decommissioning services and project support.
Subsea 7 will manage project management and engineering work from its office in Aberdeen, Scotland.
Subsea 7 UK and Canada vice-president Phil Simons said: "We are pleased to announce the signing of this important long-term agreement.
"The continuing relationships we have with each of our DSV clients is testimony of the shared objectives maintained since the original award, and its success in generating increased value opportunities."
Separately, the company said it will introduce its high pressure-high temperature (HPHT) pipeline bundle capabilities at Subsea Expo taking place from this month in Aberdeen.
HPHT address the technical and economic challenges faced during subsea pipeline design.
