CMP Finishes Pontoon Berthing Facility for DONG
DONG recently awarded Commercial Marine and Piling Ltd. (CMP) a contract to construct & install a complete berthing system for the crew transfer vessels in Barrow in Furness.
The contract included dredging, socketing piles into rock and construction of heavy concrete pontoons on site and the fabrication and installation of steel access platform and bridge. The pontoon facility was regularly tested close to its maximum design conditions on a number of occasions between December and February 14th.
Wind gusts of 45 m/s (160 km/h) were recorded locally (12.2.14) and waves in excess of 1.2 meters approaching from the south have been observed at the pontoon berthing facility on a number of days.
On 3rd January 2014 the highest ever recorded water level was experienced at Barrow with a high tide of more than 11 meters bringing the water level close to the top of the quay edge and the decks of the pontoons close to 1 meter from the tops of the piles.
The pontoon and services facility performed as designed and without problems. They demonstrated to be a very safe and stable berthing facility for use by DONG vessels and personnel in all weather conditions.
