Subsea Cable Splicing and Termination

We understand that reliable cable splicing and termination design is critical for the correct installation and long, reliable service life of subsea cables and umbilicals.

To maximise quality control, we manufacture complete mechanical assemblies including electrical, fibre and hydraulic connectors. We also offer water blocks, strain terminations, and bend restrictors.

Strategic Spares Management

As part of our strategic approach to supporting you, we store and manage supplies of critical spares including connectors and sensors. Alongside strategic spares, we offer Legacy Locker, our open industry portal for re-manufacturing and recycling and upcycling of subsea equipment.
