Subsea Power & Control

BPT has developed a simple, normally unattended buoy to provide power, control & chemicals at the wellsite, eliminating the need for an umbilical exporting services from the host.  Adopting this approach minimises the tieback's impact on the host and extends the distance at which a tieback is technically and economically viable.

The Utility buoy provides key services at the wellsite required to overcome flow assurance and control constraints without the need for an umbilical from the host facility. 

Key Benefits
  • Unattended floating system moored at well site.

  • Interfacing with the subsea system via a short dynamic umbilical

  • Remotely controlled and monitored from a manned control station 

  • Providing chemicals, control signals, power to the subsea production system

  • Eliminating the need for a long-distance static umbilical

  • Minimising land crossings and onshore interfaces.
