After the contract got by Wood group, Subsea 7 announced today that BP awarded the British engineering company a contract as part of the deepwater Mad Dog 2 development, located approximately 190 miles south of New Orleans, whose estimated value is between $300 million and $500 million, according to a Subsea7’s press release.
The contract scope covers engineering, procurement, construction and installation (EPCI) of the subsea umbilicals, risers and flowlines (SURF) and associated subsea architecture.
Subsea 7 has worked closely with BP to deliver a lump sum integrated solution from design through to supply, installation and commissioning. Furthermore, additional areas of cost improvement have been identified to provide greater cost certainty and reduced risk.
Project management and engineering will take place in Houston, Texas with support from Subsea 7’s Global Project Centre in London, UK. Offshore installation activities are scheduled for 2019 and 2020.
