Aberdeen, UK: The use of high-pressure subsea riser systems enables some subsea wells to be drilled efficiently using a jack-up rig, therefore allowing operators to achieve enhanced project efficiency and emission savings, compared to using a semi-sub with a mooring spread. The existing surface BOP system is limited however, and no good option is available to secure the well if the integrity of the riser is lost, such as in the case of a collision with a supply vessel.  The K-BOS E-SID can be integrated into the riser system and serve as a secondary barrier latched to the subsea wellhead.

Shown above: An illustrated “bow tie” diagram demonstrates the hazards, controls and mitigations for well control using a subsea high-pressure riser system. The lack of a seabed isolation device results in an unmitigated loss of well control if primary well control is lost below the surface BOP.

Adding the K-BOS at the mudline to the subsea high-pressure riser configuration allows operators and drilling contractors to clearly demonstrate to and regulators the dramatic risk reduction on this type of activity by providing an enhanced shearing and sealing seabed isolation device. In contrast to traditional hydraulic alternatives, the K-BOS E-SID is compact, easy to run and features multiple actuation options and minimal rig independent surface controls.

Key Features & Benefits:

  • Enhanced Shear & Seal Capability
  • Secondary Barrier latched to subsea wellhead
  • Easy to run, multiple actuation options
  • Minimal rig independent surface controls

Shown above: the K-BOS E-SID can be easily integrated into a subsea high pressure riser system as a seabed isolation device and provide an innovative well control barrier thus significantly reducing the risk of a blowout during use of Jack-ups and subsea high pressure riser systems on subsea wellheads.
