T&D have supplied 50off Open Ended Cable Grips (Lace Up) type to suit 120mm diameter subsea cables. The cable socks were made to order and delivered to the site office of Harwich Navyard Wharf, Essex within 5 days. The Rigging Supervisor for Subsea Cable Works at CT Offshore required the cable grips to urgently support and pull subsea cables from vessel to shore.

T&D also stock and distribute a comprehensive range of Cable Preparation, Cable Jointing & Stripping Tools for subsea cables.

Umbilicals form the critical link between a subsea production arrangement and a remote facility providing control, power, communications and chemical services. Applications include production control, chemical injection, subsea pumping and processing, gas lift and underground gas storage among others.

Umbilical system design is determined by several factors including water depth, function, environmental conditions and temperature. Technip Umbilical Systems’ experienced and dedicated engineering team provide the optimum design for its clients and their needs.

Umbilical Functions

• Steel tube and/or thermoplastic hose fluid conduits to provide hydraulic control and chemical injection service
• Low voltage electrical power and communications provided via signal cables, fibre optic cables and power conductors
• Medium voltage electrical power conductors Chemical injection lines for use in corrosion inhibition and prevention of wax and scale build-up
• Large bore centre tubes for bulk chemical injection or gas lift functions

Lace up cable socks allow cable pulling where access to the cable end is not possible.
