The KLAW Marine Breakaway Coupling (Marine BAC) protects assets, personnel and the environment during offshore transfer operations.

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

The KLAW Marine BAC therefore delivers two distinct safety features.

* Closure of media flow: then;

* Allowing separation of the hose transfer system.

Separation relieves stress on the hose transfer system and minimises risk of damage and spillage.

The KLAW Marine BAC prevents damage to assets, injury to personnel, contamination of the environment and extended downtime.

The KLAW Marine BAC protects against:

* Vessel movement or loss of dynamic positioning.
* Adverse weather conditions such as storms.
* Pressure surge within the transfer system.

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

Double closure on activation

When the KLAW Marine BAC activates, the Flip-Flap Valve mechanism closes on both the upstream and downstream flow within the hose transfer system. This minimises spill on both sides of the hose
transfer separation.

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 rigours 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.

Instantaneous closure

Spill on activation is minimised by instantaneous closure of the Flip-Flap Valve mechanism.

The typical response closure time is between 0.2 and 0.5 seconds. (Dependent on pressure, flow and media density.)

100% shut-off

Delivering 100% closure and shut-off of upstream and downstream flow.

Minimum headloss

The KLAW Flip-Flip Valve design delivers minimum headloss when in the open position, compared with other valve designs.

Minimising risk during offshore transfer

Activation may be caused by events or situations that would 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 Marine Breakaway Coupling 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-pressurisation. The activation setting is pre-determined to suit the operating conditions.
