Marine Breakaway Couplings

KLAW Marine Breakaway Couplings protect assets, personnel, reputation and also the environment during offshore transfer operations
Marine Breakaway Couplings minimises risks in offshore transfer
The KLAW Marine Breakaway Coupling offers an identified and safe parting point in the hose transfer system. When tensile forces exceed predetermined tolerances, the Marine Breakaway Coupling activates.
The KLAW Marine Breakaway Coupling then delivers two distinct security features. An example may be the closing with the flow with the media being transferred; the second thing is allowing separation in the hose transfer system. Separation relieves the hose transfer system and minimises probability of damage and spillage.

Minimising risk during offshore transfer
Activation may be due to events or situations that may prove disastrous without it proven and vital the main transfer system. Events including vessel movement, storms and pressure surge could compromise hose transfer systems and affect assets, difficulties for personnel, contamination from the environment and extended downtime. It might result in disruption of operation, extensive clean-up costs, litigation and damaged reputation. The KLAW Marine Breakaway Coupling is thus an essential part of maintaining a reliable offshore transfer system.

Typical events
Vessel movement and decrease of Dynamic Positioning (DP).
Pressure Surge: Caused by inadvertent downstream valve closure elsewhere within the system or over-pressurisation. The activation setting is pre-determined to fit the operating conditions.

Double closure on activation

When a KLAW Marine Breakaway Coupling activates, the Flip-Flap Valve mechanism closes upon the upstream and downstream flow within the hose transfer system. This minimises spill upon sides on the hose transfer separation.
Instantaneous closure
Spill on activation is minimised because of the instantaneous closure on the KLAW Flip-Flap Valve mechanism.
100% shut-off of flow
The KLAW Flip-Flap Valve mechanism provides 100% closure and as a consequence 100% shut-off of both upstream and downstream flow.
Minimum headloss
The KLAW Flip-Flip Valve was designed to deliver minimum headloss a lot more the locked open position inside Breakaway Coupling. This allows the coupling to deliver transfer efficiencies together with minimising potential risk of spills.
Reliable performance inside the marine environment
The KLAW Marine Breakaway Coupling is created specifically to withstand those bending moments and torsional forces expected from floating wave motions and the rigours in the marine environment. The design of the KLAW Marine Breakaway Coupling therefore prevents premature activation from the unit and protects the Breakstuds from fatigue.
