Subsea systems

Investment and development of subsea technologies supports operators to achieve:

  • cost efficiencies (CAPEX and OPEX)
  • greater system capabilities to deal with the more complex requirements of future field developments

Operators can rely on an active and innovative UK supply chain developing and offering subsea solutions in this space, and the majority of technology projects have vendors’ participation.

Industry insights

  • Advances in subsea inspection, monitoring technologies and  improved corrosion resistant materials are helping to maintain and extend the life of vital subsea infrastructure
  • Novel pipeline materials, alternative jointing technology and innovations in flow assurance can support efficient tie-backs and low cost marginal developments
  • The majority of technologies are developed by vendors, or in partnership with vendors and should be considered for wider utilisation and concept select
  • Technology development is critical for operators to maximise on current developments and future opportunities. Many will have harsh and challenging conditions (e.g. deep water, HPHT, H2S)
  • Future cost and operational benefits will be delivered by emerging technology developments (e.g. electric subsea systems, local hydraulic and/or chemical storage and local power supply and generation)
