Co-venturers Talisman Energy (UK) Ltd and Scottish and Southern Energy awarded JDR Cable Systems the contract to design, manufacture and test two composite subsea power cables required to control two jacket platform based wind turbines linked back to the Talisman operated Beatrice Platform.
The 2 composite bundles, 970m & 1920m long, each comprise 3 phase 70mm² 33kV power cores, data cables, back up power cables and fibre optic communications. The bundles were engineered to give the smallest diameter whilst still maintaining the strength and weight required to suit the field installation and service conditions. The termination package includes JDR’s in-house developed and designed high strength flexible pull-in head.
JDR Cable Systems also provided experienced technicians to terminate the cables and fibre-optics offshore during the installation phase.
The Beatrice A complex is the centre for gathering and processing oil from Talisman’s Beatrice Field. The production and drilling facility is manned by about 40 workers and currently produces over 5,000bbls/day, exported via pipeline to the onshore oil terminal at Nigg on the north coast of Scotland.
The Beatrice Offshore Windfarm is part of the European Union’s DOWNVInD (Distant Offshore Windfarms with No Visual Impact in Deepwater) project, established as a catalyst for commercialising deepwater windfarm technology.
The origins of this project lie back in 2001 when a deepwater offshore windfarm distant from the shore was initially conceived. DOWNVInD comprises 14 different participants from six countries and is Europe’s largest renewable energy research and technology development programme. The demonstrator project comprises two 5MW wind turbine generating units located 25km from shore on the seabed, linked to the Beatrice AP platform by a subsea cable.
Lasting for approximately five years, the demonstrator project will examine the feasibility and benefits of creating a commercial deepwater windfarm at this site. The energy generated by the turbines will be used to power the Beatrice AP platform, reducing the use of power from fossil fuels and their associated emissions.
JDR Cable Systems are proud to have played a role in this project; a scheme that has pioneered the development of deepwater windfarms, delivered a better understanding the environmental impact and provided the opportunity to share knowledge and best practice across Europe.
