The 84 Series coupling is a cartridge mount coupling used primarily for subsea tree control systems. Testing has shown that up to 500 connect/disconnect cycles can be performed without damage to the metal seal. The highly reliable 84 Series coupling has been extensively tested, with thousands currently in use today.
The Walther SH Series, also referred to as the "White Rose" Series couplings are a diver operated, screw-together type coupling, with design features allowing easy diver connection and disconnection.
The WALTHER IDHS connects to a hot stab receptacle like any other standard unit. However, it has 2 redundant supply lines attached. The internal valve design ensures that a damaged line will be isolated automatically while the other line takes over and the system stays operationable.
Subsequently, the hot stab can be disconnected and replaced during a scheduled maintenance at any convenient point in time. Even if both lines fail, the system automatically vents the receptacle.
The design is based on two requirements, which are reliability and ease of use. For the implementation of these parameters, only proven technology and components were used. As a result, this system allows the customer to operate easier and quicker compared with existing systems.
The modularity of the approach ensures different versions without compromising the proven technology.
