UT2
This month secc make waves in the marine and subsea world according to UT2 Magazine The Magazine of the Society For Underwater Technology, covering our hot-make hot-break coupling.

Press Release
Pipe and hose coupling design engineers; secc Oil & Gas have developed the first Full Bore Subsea Pressure Balanced Safety Breakaway Coupling specifically for subsea high pressure hydraulic/chemical injection work-over operations and for Gas Lift Jumper Connectors.

The secc coupling gives significant protection to trailing high pressure lines from the support / intervention vessel to the subsea infrastructure in the event of loss of vessel DP or other emergency causing the vessel to “pull-away” while the high pressure lines are still connected to the vessel.

Because of its unique Pressure Balanced design, the coupling/ connector has no separation forces acting on the two coupling interfaces (coupling will not blow apart) and has the capability of working at seawater depths of over 10,000 ft (3,000 mt’s) and with line pressures of over 15,000 psi (1,035 bar)

Used in a Gas Lift Connector application, the coupling gives many advantages over the existing technology, allowing a “Dry Break” disconnection and re-connection of the Gas Lift connector entirely by ROV.

The coupling has the following features & benefits:

  • No separation forces acting on the coupling when pressurized 
  • No separation forces acting on the two halves of the coupling as it separates
  • 100% shut-off as coupling separates (Dry Break)
  • Coupling can be ‘Made’ under full line pressure (full pressure on both sides of the coupling)
  • No pressure constraints in terms of the bore size (15,000 psi max)
  • Can be actuated by a pipeline pull/tug of up to 15º from the perpendicular of the coupling.
  • No depth of seawater constraints, coupling will work on the surface or at 10,000 feet (or greater)
  • Bore sizes from ¾” to 4¹/16" (Larger sizes for pipeline applications are available)
  • No pressure loss across the coupling (Full Bore Design)
  • Coupling sheer pin break-out strength can be easily defined
  • Coupling can be mounted to fixed subsea structure (Xtree & Jumper)
  • Coupling can be actuated by either tensile pull or diver/ROV removal of coupling sheer pin.
  • Coupling provides for the safe transfer of a variety hazardous fluids and gases.
  • Coupling designed to API 6H/API 17D, DNV “Statement of Feasibility” pending.
