Gwynt Y Mor Wind Farm – Assembly area

RWE npower are responsible for the construction of the Gwynt Y Mor wind farm, a major 576MW wind energy project located off the north Wales coast. In preparing the onshore facilities for the wind farm construction, they leased an area of the Cammell Laird shipyard in Birkenhead to store and fit out the wind turbine components ready for assembly at sea. The quay they leased was constructed in the early 1900s, and the quay walls were known to have been partially built on timber piles. This meant that the structure was potentially vulnerable to movement or damage from any large operational loads on the quayside.

We were commissioned to provide consultancy services for the lease agreement - including site investigations and condition surveys of the existing facilities - and then to strengthen the quay to enable it to accept loads from the large cranes required to manoeuvre the wind turbine components. We were also asked to assess the impact of the transport vessel jack-up ‘feet’ on the stability of the quay wall. This led to the design of a method for ensuring that wall stability was maintained during the works.

A further commission included the design of steel ‘stillages’ and frames to allow movement, upending and fit out of the components, and then the design of material bunds in the ‘laydown’ area to store the components ready for fit out and construction.
