news item image
Collett has successfully delivered two 160TE inlet valves to Dinorwig hydropower station as part of an essential upgrade scheme.
Working on behalf of Rhenus Project Logistics, the Collett team completed the first two deliveries of the project, a significant accomplishment marking a crucial milestone in the ongoing upgrade project.
The upgrade scheme is aimed at extending the power station’s operational lifespan for the decades ahead.
A total of six valves will be delivered to complete the project, with each valve weighing 160Te.
The first two inlet valves arrived at the Port of Penrhyn, located East of Bangor, North Wales. Working under CPA Contract Lift Conditions, the company discharged both valves from the vessel using an 800Te mobile crane.
Upon arrival at the power station, the two main inlet valves were directly transported to a designated storage area and lowered onto stools.
After later preparation, the valves were transported into the mountain and offloaded by overhead gantry cranes.
Dinorwig Hydro-Electric Power Station, located near Llanberis in the Snowdonia National Park, is the largest pumped hydroelectric storage facility in the UK.
With a maximum power supply of 1,728MW and a storage capacity of approximately 10GWh, the station efficiently manages water between the Marchlyn Mawr reservoir and the Llyn Peris Lake to generate power as needed.
