Hose End Valve
The Hose End Valve (HEV)/North Sea Valve (NS)/Outboard Hose Termination Piece (OHTP) is an integral part of an offloading system on-board an FPSO. Its primary function during an offloading operation is to connect the offloading hose string to a coupler on-board the receiving shuttle tanker. The HEV is self-closing, during an emergency release event the valve closes shut (fails safe) and prevents spillage of the offloading hose contents.
- Design, manufacture and tested in accordance with Petrobras Specification for North Sea Valves I-ET3010.00-1359-220-PY5-001, API 6D Specification for Pipeline and Piping Valves
- ABS Certified - 21-2095378-PDA / DNV Design Approved
- The design is compatible and interchangeable with dedicated shuttle tankers fitted with standard bow loading systems
- We have an installed base of more than 100 HEV’s supplied and operational worldwide.

Marine Couplings
Emergency Release Couplings (ERC)
Emergency Release Coupling (ERC) will provide an active method of disconnection of the offloading hose string from the FPSO manifold. The ERC release signal activates an interlocked sequence of valve closure, valve close signal, then continues to release.
- 16” - 24” NB 150# or 300# flanges
- Double acting ‘open’ and ‘close’ function
- Double valve closure (close before release interlock)
- Active activation
Marine Couplings
Marine Break-Away Coupling (MBC)
Marine Breakaway Couplings (MBCs) provide a passive method of disconnection of an offloading hose string. The MBC automatically activates a sequence of valve closure either when there is excessive tensile load on the hose string or an unacceptable surge in flow. The MBC then continues to separate.
- Double Closure, passive activation (break studs)
- 16” - 24” bore
- Full-bore, zero headloss
- Piggable
- Adjustable closing time
