A port which claims to be the UK’s largest sustainable marina of its kind has been completed at Osprey Quay, Dorset, England.

Dean & Reddyhoff’s £27m, 600-berth Portland Marina, designed and engineered by Atkins, has been built on a former Royal Navy Air Site.

The project is part of an overall site-wide masterplan being delivered by the South West Regional Development Agency.

Three 20kW wind turbines will provide around 10% of the site’s energy needs.

Portland Marina has no natural inlet to provide shelter for its 600 berths, but an 860m breakwater has been built to house pontoons to provide the moorings.

Other facilities include a boat dry-stack building to accommodate 180 small craft and five large engineering units to accommodate a 50t mobile boat hoist.
