SUBSEA Cable Accessories
Bespoke Engineering Solutions
The name W T Henley has been synonymous with Subsea Telegraphy and Power Distribution since the company was founded in 1837.
We have an impressive track record of supplying many of the world's largest Utilities, Gas and Oil majors with specialised subsea cable accessories, essential to enable the installation and maintenance of Subsea power and communication distribution systems.
In more recent years W T Henley has been in the vanguard of development to support the rapidly growing market associated with offshore power generation from renewable sources.
Special Products
Our product range includes specially designed pulling heads to ensure that torsionally balanced cables safely reach their destination (at the platform) as well as temporary and permanent armour clamps.
Other products include explosion proof cable termination boxes, 'J' tube bungs, bend stiffeners and cable repair joints.
Typical Products
Pulling head
To enable the safe installation of the cable to the platform or riser deck, WTH have designed a pulling head which connects directly onto the cable armour layer(s). This ensures that all mechanical forces associated with pulling the cable via the ‘J' or ‘I' tube are borne by the armour with minimal transference of strain to the underlying components.
Hang off
Once installed and at the top of the 'J' tube the cable is mechanically secured by the installation of a hang off clamp. The cable armour is terminated within a clamping arrangement that ensures the mechanical stresses expected to occur during service life are safely borne by the cable structure. Where appropriate, Cable hang off's can be supplied combining core breakout and/or jointing to topside cable.
Repair Joint
For the repair and maintenance of Submarine Transmission and Distribution systems, WTH have designed and developed a family of repair joints capable of enduring the extremes of mechanical and electrical stresses encountered during system installation and operation.
Other Accessories
In addition, WTH can provide the full range of accessories required to enable the successful installation and operation of a full range of Electrical or Composite Electrical/Optical Submarine Cables and Umbilical's including
Beach Clamps
Beach/Transition Joints
Bend Stiffeners
Bend Restrictors
