Description

Offshore cable hang off helps secure medium and high-voltage power cables to the top of a foundation/cable deck of a monopile, jacket, or rig.

Cable hang-offs clamps provide structural support between the riser or umbilical and the outer J-tube. Systems can also be supplied with a sealed module that provides full sealing capability in the annulus between the riser and the J-tube. The topside hang-off clamps is fitted with a continuous housing that is preinstalled prior to riser pull-in.

Key features

•Quick and efficient assembly process

•Temporary clamp pressure <3MPa (most existing designs exceed this)

•Reduced stick distance from the hang-off flange in order to support the core routing and termination

•Optimised for sealing when used on a monopile foundation and passed tests in over 3 bar of pressure (most existing designs reach up to 1 bar)

•Reduced sealing resin requirement (typically 2-3 litres whereas most existing designs use up to 10, which is a H&S risk)

Philsonare able to offer either a bespoke design or make use of a vast array of existing designs of J-tubes to suit a wide range of pipes, umbilicals and cables. The height, material and shape of riser hang off flange can be customized.
