Smart Subsea Solutions

Uncover the
true value

At Subsea Integration Alliance we believe in the value to be made from bringing everything together. Through a process of collaborative engagement our teams work together digitally across their specialist areas, whilst Subsea Integration Alliance customers still benefit from a single point of contact, and an early engagement framework tailored to their individual requirements. We retain a partner-focused mindset throughout our work using our value delivery framework.

Value delivery framework

The value delivery framework reflects the key real-world drivers of our customers. The approach of Subsea Integration Alliance considers every aspect of it when developing solutions - keeping an open mind and a balanced view to unlock as much value as possible from each project.


Taking a system-wide view on the combined costs of SPS and SURF, well construction, topsides, process and hosts-standardising interfaces and identifying the most capital-efficient options.


Understanding the ongoing costs of subsea operations including manpower, logistics, chemical and power consumption, and factoring in less visible expenses such as inspection, intervention, maintenance and repairs.


Identifying the financial impact of any taxes resulting from projected CO2 emissions, with the option to build in technologies to control or actively reduce the carbon footprint of operations.

Uptime & Reliabilty

Exploring ways to maximise the availability of subsea and topside facilities, as well as opportunities to reduce the incidence of shutdowns and lessen the impact of start-ups.

Incremental Recovery

Engaging subsurface expertise to connect subsea systems with asset recovery to help avoid under-recovered reserves and optimise the value of additional hydrocarbons produced.

Accelerated Recovery

By quickly defining the best solution, and developing it faster, Subsea Integration Alliance shortens the time to first oil, resulting in shorter payback time.

Unlock the true value

Early collaborative engagement utilising our subsea value framework enhances investment returns across subsea projects.

Murphy, Dalmatian Field

Schedule acceleration

Gulf of Mexico, Dalmatian Field​

Murphy sets length and efficiency records with integrated EPCIC solution

Longest deepwater multiphase boosting tieback and shortest implementation time achieved with Subsea Integration Alliance.

As a result of the integrated EPCIC solution delivered by Subsea Integration Alliance, Murphy set records for the longest deepwater subsea multiphase boosting tieback (22 miles) and for the shortest subsea boosting implementation from concept to start-up.

Murphy sought an integrated approach while developing the Dalmatian field in deepwater Gulf of Mexico. Early technical engagement by Subsea Integration Alliance during field development planning resulted in viable project economics, and combining project execution, engineering, HSE, and quality philosophies helped enhance efficiencies.

TAQA, Otter Field

Smart system solution

UK North Sea, Otter Field

TAQA achieves record-breaking 18-mile tieback in UK North Sea

Integrated solution included using subsea delivery of multiphase pump as alternative to ESP

Multiphase pump technology leaving Horsoy, Norway for the Otter field in the North Sea. Coupled with the long-distance tieback, the subsea boosting technology provided production security for the late-life asset.

TAQA approached Subsea Integration Alliance for a solution that would provide production security for a late-life asset, the Otter Field, resulting in installation of the longest subsea boosting tieback in the UK North Sea (18 miles [30 km]). The tieback uses a multiphase pump as an alternative to Electrical Submersible Pump (ESP) for enhanced production. Boosting technology will enable TAQA to finish production on the Eider platform on schedule and keep Otter Field in production.

BP, Mad Dog 2 Field

Delivery assurance

Gulf of Mexico, Mad Dog Field

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

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

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

BP required several integrated components and services to reduce costs and enhance efficiencies in its Mad Dog Phase 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.
