JDR Cable Systems the umbilical and subsea power cable division based at Littleport, Cambridgeshire, UK. JDR's market has now expanded and changed- a lot. " Our subsea products can be permanently installed on the sea bed, providing hydraulic and electrical control to offshore oil and gas production fields," says Phelan.

So at the beginning of 2008, the company began developing a new facility at Hartlepool, located on the UK's east coast, that will specialise in the production of the larger- specification cables. " We developed into the production of subsea power cables about eight years ago. We did those from Littleport- up to about 100 tonnes- and we are continuing to serve that market from our original site," says Phelan. " In 2005 we supplied our first offshore wind farm, the Beatrice demonstrator." The cables are rated to 33 kilovolts and JDR's specialism is the pull- in process, which involves connection to the turbines and to the control station. It recently won a contract to supply an offshore wind farm containing up to 140 turbines, which means 280 cable ends.
