Subsea Dynamic Power Cables

BPP-Cables provides cable solutions for demanding applications. It is a subsidiary of BPP-TECH and Keppel Offshore & Marine. Keppel Offshore & Marine is the global leader in offshore rig design, construction and repair, ship repair and conversion, and specialised shipbuilding.
Engineering and supplying cables for submarine, onshore, downhole and specialist applications, BPP-Cables reduces the risks to both operators and manufacturers. BPP-Cables is partnered with manufacturers developing leading-edge cable solutions for the offshore energy sector.

Our cables division BPP-Cables develop advanced marine cable designs, which consistently exceed performance expectations.

BPP-Cables' 100 MW, 132 kV dynamic AC marine electrical cable provided a step change in subsea power cable technology. It is enabling technology for high power transmission through the moving water column, from surface vessels or installations, down to depths in excess of 2000 m (6500 ft.)
BPP-Cables has developed critical components of submarine and downhole AC & DC cables. This results in solutions that improve cable performance, extend service life, and reduce costs. They use component technologies that include fluid barriers, optimal materials, configuration design and load management. AC and DC cables upto 150 kV have been developed, rigorously tested and verified, both electrically and mechanically.
The cable specification is critical as this is the foundation of a robust high performance, efficient cable.
