Description
200m L x 80m W x 12m H pre-stressed post-tensioned reinforced concrete floating dock for Vanguard class ballistic missile submarines including: steel framed aluminium clad building over the dock; two high integrity overhead electric travelling cranes for nuclear missiles and torpedo loading operations; mechanical and electrical systems including extensive cupronickel bilge and ballast pipework, 50m W x 40m H ship door and ship support systems; two x 60m L steel trapezoidal form access bridges; two x 80mL V shaped 3m dia steel mooring booms and steel floating caisson dock gate. The access bridges and mooring booms required highly complex bearing arrangements to take up large tidal movements and severe environmental conditions. The project required a high level of operational and safety reliability which was reflected in the design and the change control safeguards. The completed weight is 100,000 tonnes (approx).
Constructed in specially enlarged dry dock at Hunterston (Ayrshire) and towed up river to the Royal Naval Armaments Depot at Coulport (Dunbartonshire) for completion and fit-out. The building frame, access bridges, mooring booms and caisson gate were constructed in Belgium and Holland and delivered by sea, for the hook-up operation at Coulport.
