The Port of Mostyn Ltd is located in the central Irish Sea where it has been a significant trading point between the U.K. and Ireland for over 400 years. With recent expansion and modernisation Mostyn has been developed to become one of Europe’s most important ports for the offshore renewable energy sector.


Clients & Projects:

Offshore Windfarms: Commencing in 2004 the first two major offshore windfarm construction projects in UK waters were undertaken using The Port of Mostyn.  Since that time, seven Irish Sea offshore windfarm projects have been undertaken from the Port namely: Burbo Bank in the River Mersey, Robin Rigg, located 98 nautical miles distance in the Solway Firth and Walney 1 and Walney 2 off the Lancashire coast. 

Off the Welsh coast both the North Hoyle and Rhyl Flats projects were constructed from Mostyn. The 160-turbine Gwynt-y-Mor windfarm located approximately 15 miles off the Welsh coast, in addition to being a windfarm construction port, Mostyn is also the Operations and Maintenance (O & M) Base for RWE’s North Hoyle, Rhyl Flats and Gwynt-y-Mor windfarms for the duration of their 25 years operational lifespan.

Windfarm developers who have used Mostyn include RWE Npower and Dong Energy; the major contractors and turbine manufacturers such as Siemens Wind Power A/S and Vestas Wind Technology; and the major construction contractors Van Oord and MT Hojgaard A/S.

In addition to facilitating the offshore renewables sector, the Port also handles project cargoes and aggregates for the construction sector. With 300m of quay and a dedicated Roll on Roll off berth the Port offers clients flexibility and capacity to handle most cargoes.
