Atkins has completed a three-year-long construction on the Portland Marina located at Osprey Quay in Portland Harbour, UK.
The £27m marina was built by Dean & Reddyhoff Marinas and is sited on a former Royal Navy air base, while South West Regional Development Agency (SWRDA) delivered the site's master plan.
Portland Marina will host the sailing events during the London 2012 Olympic and Paralympic Games.
It is also an approved training centre for Olympic teams.
Marina has 600 berths, of which 250 will serve as on-shore facilities during the event.
The sustainable marina is equipped with three 20kW wind turbines, which provide 10% of the marina's energy.
The marina is equipped with a 860m breakwater to house the pontoons for the mooring purpose.
The breakwater was built by contractor Raymond Brown using local 200,000t Portland stone.
The new marina features shore facilities as well as a bar, restaurant and retail units, 15 business terrace units, a boat dry-stack building for 180 small craft and five engineering units to house a 50t mobile boat hoist.
The venue is also equipped with a floating fuel berth and has landscaped gardens.
