Supply of HV Export Cable Range Taking Repair Joints
Power CSL Scope
Design and supply of high voltage (132-150kV) range taking joints for UK OFTO export cable assets.
Background
A UK OFTO Client required a number of HV cable repair joints that would cover all of their OWF export cable assets. The key requirements were :-
- Cable range 300mm2 to 1200mm2
- Voltage range 132kV to 150kV
- Ability to connect cables from different manufacturers (to maximise availability of spare export cable across the fleet of OFTO’s OWFs)
- Ability to connect cables of different conductor size (should this be required)
- Ability to accommodate a range of optical fibre designs within the export cables
After a comprehensive design review covering engineering of all of the possible connection permutations it was confirmed that the PCSL range taking HV repair joint met all of the Client requirements.
The joint kits were subsequently manufactured. A long term agreement was established with the OFTO’s framework marine installer whereby PCSL stored and managed the joint kits, with replacement of any shelf-life sensitive components as they expired. This approach ensured that the joint kits would always be available for rapid call-off to port in the event of an emergency cable repair requirement arising.
Power CSL Deliverables
- Supply of repair joints based upon PCSL range taking design
- Long term storage and component management of the repair joint kits
- Provision of Product Familiarisation Courses for teams of offshore technicians if required
Outcome
All products and services were supplied on time to the agreed technical specification.
