InterMoor has been contracted by Subsea 7 to provide mooring and tow services for BP’s Mad Dog 2 project in the US Gulf of Mexico, InterMoor announced today (11 September).
The contract's scope includes InterMoor securing the new semisubmersible production platform at depths of 4440ft. InterMoor will install the new Mad Dog 2 platform, which includes wet tow and mooring installation, the company said.
After re-evaluating the project in 2013 to reduce initial costs of $20 billion, BP in December 2016 sanctioned the project at a cost of $9 billion. Mad Dog 2 is an extension of the Mad Dog field, one of BP’s largest Gulf of Mexico discoveries to date. The current Mad Dog platform has the capacity to produce up to 80,000 bbl (gross) and 60 MMcf/d of natural gas (gross).
In January this year, BP awarded to Samsung Heavy Industries the $1.27 billion contract to build the Mad Dog 2 floating production unit, which will weigh 58,000-ton or above, with 110,000 b/d and 25 MMcf/d gas capacity. The second Mad Dog platform will be moored about 6mi to the southwest of the existing Mad Dog platform, which is in 4500ft water depth, some 190mi south of New Orleans.
In March, BP awarded Subsea 7 and Schlumberger contracts under the Subsea Production Systems alliance with OneSubsea to conduct subsea work for the Mad Dog Phase 2 project. Subsea 7 also received a lump sum engineering, procurement, construction and installation contract for the subsea umbilicals, risers, flowlines and associated subsea infrastructure.
BP in May awarded Dresser-Rand the contract to provide rotating equipment for the project, including two DATUM compressor trains.
