Read more about the Marine Breakaway Coupling Mk1

The KLAW Marine Breakaway Coupling provides an identified and safe parting point within the hose transfer system. When tensile forces exceed predetermined tolerances, the Marine Breakaway Coupling activates.

The KLAW Marine Breakaway Coupling then delivers two distinct safety features.

The first is the closing of the flow of the media being transferred; the second is allowing separation of the hose transfer system.

Separation relieves the hose transfer system and minimizes risk of damage and spillage.

Minimizing risk during offshore transfer

Activation may be caused by events or situations that could prove disastrous without this proven and vital part of the transfer system. 

Events such as vessel movement, storms and pressure surge could compromise hose transfer systems and cause damage to assets, injury to personnel, contamination of the environment and extended downtime. 

This might lead to disruption of operation, extensive clean-up costs, litigation and damaged reputation. 

The KLAW range of Marine Breakaway Couplings is therefore a crucial part of maintaining a reliable offshore transfer system.
 

Typical events

  • Vessel movement and loss of Dynamic Positioning (DP).
  • Pressure Surge: Caused by inadvertent downstream valve closure elsewhere in the system or over-pressurization. The activation setting is pre-determined to suit the operating conditions.
 

Performance and features

Double closure on activation
When a KLAW Marine Breakaway Coupling activates, the Flip-Flap Valve mechanism closes on both the upstream and downstream flow within the hose transfer system. This minimizes spill on both sides of the hose transfer separation.

Instantaneous closure
Spill on activation is minimized by the instantaneous closure of the KLAW Flip-Flap Valve mechanism.

100% shut-off of flow
The KLAW Flip-Flap Valve mechanism provides 100% closure and therefore 100% shut-off of both upstream and downstream flow.

Minimum headloss
The KLAW Flip-Flip Valve is designed to deliver minimum headloss when in the locked open position within the Breakaway Coupling.

Reliable performance in the marine environment

The KLAW Marine Breakaway Coupling is designed specifically to resist those bending moments and torsional forces expected from floating wave motions and the rigors of the marine environment.

The design of the KLAW Marine Breakaway Coupling therefore prevents premature activation of the unit and protects the Breakstuds from fatigue. 

Typical applications

  • Offshore supply vessels: Supply Vessels to/from Offshore Platforms
  • Ship-to-ship transfer
  • Ship-to-shore transfer
  • Any transfer application where protection must be fitted between two sections of flexible hose.
 

Installation and maintenance - minimum disruption to operations

The KLAW Marine Coupling, with its simple integration into flexible hose systems, enables diverse and easy installation into transfer systems.

A full range of maintenance, refurbishment and activation support is available for rig operators ensuring minimum disruption to operations.

KLAW MARINE2 is the most compact and lightest Marine Breakaway Coupling on the market: ideal for reel applications.

World-wide industry standard

The KLAW range of Marine Couplings have been widely integrated into operations all over the world. Locations include the North Sea, Caspian, Gulf of Mexico and many others.

The KLAW Marine Breakaway Coupling is the world-wide industry standard and is the most widely used model of its kind in the world.
