Narec installs anemometry platform for Blyth demonstration site

Friday, 30 November, 2012 - 15:00

The British National Renewable Energy Centre (Narec) has completed the installation of an offshore research and anemometry platform, three nautical miles off the coast of Blyth. The platform is fitted with the latest technologies for measuring wind resource, observing marine conditions and collecting marine life data.  At a height of 103 m above sea level, its meteorological mast is amongst the tallest planned for offshore wind in the UK and the data collected will validate conditions on the proposed 100 MW demonstration site for next generation turbines up to 8 MW. 

Andrew Mill, Chief Executive at Narec, said: “The installation represents a significant step forward in the realisation of the demonstration project, which has been designed to enable the commercialisation of the next generation of offshore wind turbines and their associated structures and electrical network equipment. This is the right time for manufacturers to provide assurance to investors in the sector by building up operating hours on their new designs in a realistic offshore environment.”

The contract for the complete installation works was awarded to SeaRoc earlier this year and included transport of the foundation to the quayside, full load-out and offshore installation of the foundation, three pin piles, grouting and full topside. The structure’s 53 m high tripod foundation, weighing 535 tons, 60 ton platform and a 25 ton meteorological mast were assembled offshore after being collected from the manufacturers on the River Tyne. 

The platform has been designed for a 22-year life and its installation on a tripod structure at 37 m water depth follows the approach being taken for the installation of wind turbines in deep waters. As well as providing a benchmark for tenants to monitor the performance of turbines on the Blyth Offshore Wind Demonstration Site, it provides an open-access research facility to trial new technologies and processes to reduce the timescales and costs of consenting offshore wind.

Mill adds: “To reduce the future costs of up-scaling offshore wind requires innovation through the whole process of design, manufacture, installation and operation of wind farms, particularly as we go into deeper water farther out at sea.  Our North Sea demonstration site provides a microcosm of the environment in which the majority of UK Round 3 sites will be built out in.  We are providing a shop window in water depths ranging between 35 m and 58 m for tenants to prove the performance and durability of larger prototypes and early-series production models.”
