BP improves risk management and reduces costs in deepwater Gulf of Mexico.

  • Water depth range
    4,600–7,100 ft [1,400–2,160 m]
  • Project type
    Greenfield development with floating production unit
  • Awarded: 2017

Holistic approach by Subsea Integration Alliance improves risk management and reduces costs in deepwater Gulf of Mexico for BP.

Subsea Integration Alliance delivers efficient SPS and SURF services in first large-scale integrated subsea development.

As a result of all aspects of the technical solution being integrated for full efficiency, Subsea Integration Alliance is helping BP reduce costs, increase execution predictability, and improve technical and delivery risk management.

Background
BP required several integrated components and services to reduce costs and enhance efficiencies in its Mad Dog 2 project. Subsea Integration Alliance provided a supplier-led technical solution that integrated subsea production systems (SPS) with subsea umbilical, riser, and flowline (SURF) services.

PROJECT UPDATE

Major milestones completed in Mad Dog 2 project

Subsea Integration Alliance is proud to announce the completion of both the Seven Pegasus and Island Venture vessel campaigns in the BP Mad Dog 2 project, with the successful delivery and installation of mooring piles and OneSubsea manifolds.

Milestones and achievements during this phase of the Mad Dog 2 project include:

  • 548-day completion, from fabrication of the mooring piles to full installation
  • 12 mooring piles and four holdback piles installed, the biggest measuring 27 m high and 6 m in diameter, weighing 252 t
  • Four OneSubsea production manifolds and two water injection manifolds installed, the heaviest weighing 127 t
  • 3.5 weeks of site preparations and barge loadouts at a core location in Alabama, USA
  • Two construction vessels, two barges, four tugs, and four offshore support vessels involved for installation in the field
  • Zero safety-related incidents.

     

“I want to specifically recognise the collaboration across the teams which has enabled efficient execution while working through the many challenges. The use of technology to ensure adequate technical support and oversight while reducing our personnel needs offshore is a great success story, and no doubt something we can look to adopt more widely going forward.”
