Seabed investigation begins at nuclear power site

Furgo has begun marine site characterisation works for Horizon Nuclear Power at the proposed Wylfa Newydd power station site on the Isle of Anglesey, UK.

The works will be conducted during July and August and will help Horizon gain a better understanding of the geological conditions of the offshore the proposed site.

Two jack-up barges from the company’s fleet will undertake geotechnical drilling and sampling operations on 36 borehole locations. They are equipped with a range of data acquisition tools including rotary coring, cable percussion, cone penetration testing, and geophysical logging. Each unit will also have an RIB support craft, a crane, a drilling fluid system, welfare facilities, and an access/egress system.

The barges are approximately 500 metres out to sea at Porth-y-Pistyll, and more than 800m from the Cemlym Bay nature reserve, and will support Horizon’s proposal to establish its cooling water intake structure, marine offloading facility, and breakwater.

It will further reduce Horizon’s road haulage volume by bringing in many of the bulk materials and large components needed during construction by sea.

Furgo’s onsite management and geotechnical teams will run the simultaneous operations, core logging process and crew transfers.
