Subsea 7 Lands $150 Million Culzean Field Contract from Maersk Oil
Offshore contractor Subsea 7 says it has been awarded a $150 million subsea, umbilical, riser and flowline (SURF) contract by Maersk Oil for the development of the Culzean field in the UK North Sea.
The contract award comes just one day after Maersk Oil won approval from the UK’s Oil & Gas Authority to develop the field, said to be the largest gas field discovered in the area in more than a decade. The ultra-high pressure, high temperature field is located in Block 22/25 of the Central North Sea at a water depth of approximately 90 meters.
The scope of the contract includes project management, engineering, procurement, construction and installation of a 22″ diameter 52 km gas export pipeline connected to the Central Area Transmission System (CATS), and a 3.6 km pipe-in-pipe (10″ outer pipe and 6″ inner pipe) providing insulation for the transportation of the condensate to the in- field Floating, Storage and Offloading facility (FSO). The pipe-in-pipe will be laid with a 4″ piggy-back line that will transport fuel gas to the FSO. Subsea 7 will also provide subsea structures, tie-ins to the Culzean platform facilities and pre- commissioning expertise, according to Subsea 7.
Project management and engineering work is expected to commence immediately from Subsea 7’s Aberdeen office. Offshore activities will utilize a number of Subsea 7 vessels including the highly versatile pipelay and heavy-lift vessel, Seven Borealis. Offshore operations are scheduled to commence in 2017.
Phil Simons, Vice President UK and Canada, said: “This large project awarded by Maersk Oil for their Culzean field development, confirms our reputation as a world-class provider of reliable and cost-effective SURF solutions. The Seven Borealis has the ability to deliver fit-for-purpose performance demonstrating the optimum balance of cost-efficiency and capability. We look forward to collaborating with Maersk to ensure the safe and timely delivery of this significant gas production development.”
