The wind farm, which will be constructed 18km from the shore, is scheduled to be completed by 2019.
It will generate enough energy to power about 450,000 UK homes.
JDR will manufacture about 180km of inter-array cables for the project which will connect the proposed 84 wind turbines.
The cables will be manufactured at the company's facility in Hartlepool, UK. It is expected to start the supply in the second quarter of 2018.
The offshore wind farm will feature Siemens’ 7MW SWT-7.0-154 turbines, which will have a total height of 198.4m, with rotor diameter of 154m.
Each of the turbine will be installed on grounded jacks with average depth ranging between 35m and 55m.
The wind farm will contain two export cables, capable of transferring about 220kV. When complete, the wind farm can eliminate about 840,000 tonnes of CO2 and 19,000 tonnes of SO2 from entering the atmosphere per year.
SSE, Copenhagen infrastructure Partners and SDIC Power own 40%, 35% and 25% respectively in the project.
JDR COO Richard Turner said: “The Beatrice project highlights the UK’s commitment to investing in offshore wind energy and our contract is a great example of supporting UK manufacturing and employment.
“We are particularly proud to be working on this project, having provided our first inter-array cables for SSE’s pioneering Beatrice demonstrator project 10 years ago, which included the first 5 MW offshore turbines.”
