TTS has won a contract to design, supply and install a linkspan and pedestrian lifting bridge as part of the Rothesay Pier Ferry Berth Improvement Project.
This comes in anticipation of the introduction of the MV Argyle, one of a series of new vessels in operation on CalMac’s most frequented route between Rothesay and Wemyss Bay. These new vessels have been designed with bow and stern ramps for use with parallel berth linkspans at both ends of the route. The linkspan will begin operation in early summer.
TTS’ proposal for the new linkspan comprises a ramp hinged at the bank seat, supported by a portal structure at the dolphins. The structure will be operated with the use of four hydraulic cylinders designed to move it vertically with live loads.
The linkspan will be 30 metres long, with a driving width of 4 metres, and will be equipped with fenders, with an energy absorbing capacity of 34 tonnes meters, both at the front and at the bank seat.
The front of the linkspan will feature a slope to accommodate a variety of vessel ramp geometries, for example those of the MV Coruisk and MV Bute currently in operation. The linkspan can also be used by vessels without ramps as it is equipped with a hinged flap at the front towards the vessel. The flap is also operated by the hydraulic cylinders and will follow the vessel’s movements once positioned on the vessel shelf.
TTS will also deliver a 14 metre long lifting bridge, allowing pedestrian access over the northern end of the pier which separates the inner and outer harbours. The bridge is to hinge, with a counter balance at the hinged end. The bridge will be operated with the use of two hydraulic cylinders located at each side. The ramp will rest on a support in its horizontal position and is designed to be opened to a 75 degree angle to allow access for sea traffic.
The machinery cabinet, from where the bridge will be operated will be installed close by and will include both electrical and hydraulic equipment. Navigation signals for sea traffic will be located by the bridge.
In addition to TTS’ design and supply of the linkspan and lifting bridge, TTS Ships Equipment in Bergen has designed and delivered the vessel ramps, the company thus providing the entire transport chain from quay to vessel.
