BP’s discovery of the Mad Dog Field in 1998 is its biggest in the Gulf of Mexico to date. Initial production began in 2005, and now, the project has extended into the second development stage.

BP teamed with OneSubsea on the Mad Dog 2 project to reduce costs and enhance efficiencies via the engineering, procurement, and construction (EPC) of a supplier-led standard technical solution that integrates a subsea production system (SPS) with a subsea umbilical, riser, and flowline (SURF) system. Through the EPC contract, OneSubsea is supplying a standard subsea production system including 14 production trees, six water-injection trees, manifolds, topside and subsea controls, flowmeters, and jumpers. The first two 10,000-psi production trees have been successfully landed, locked, and tested subsea.

The journey started in late 2015 with early engagement with BP, and then moved through the tender process; execution strategizing; assembly and testing in Johor, Indonesia, and extended factory-acceptance testing (EFAT) and mini system-integration testing (MSIT) in Berwick, Louisiana; and finally, the installation in the Gulf of Mexico. This project highlights the benefits of standardization and efficient project execution. Production from Mad Dog 2 is expected late 2021.

Engineering Agility Manager Brent Gable and Program Manager Charles Henderson, OneSubsea, highlight the benefits of an agile standardization approach and efficient project execution for the Mad Dog 2 project.
