First phase of Lerwick dredging nearly complete

10 Jul 2008

The first phase of the dredging project in Lerwick Harbour in Scotland is nearing completion. Westminster Dredging Company’s dredger Waterway left Lerwick in early June after having removed close to 400,000 cu/m of seabed.

A substantial part of the area being deepened to 9m water depth has been achieved by Waterway removing the softer material, which has been pumped to a reclamation site north of Greenhead.

The backhoe dredger Manu Pekka is now removing the remainder, including rock.This rock is transported to the reclamation site by two barges and is being used to create the outer containment bund.

A drill barge, Playmate, has now arrived in Lerwick to blast the harder rock areas. Blasting started in the middle of last month and will continue until early September.

A second project being undertaken by Lerwick Port Authority is to increase the lay-down area at its Dales Voe Base. A contract has been awarded to F L Johnston to remove a quantity of material from the rock face at the rear of the Base. This rock is also being used by Westminster Dredging Company to assist the creation of the containment bund.
