Ad Hoc Marine Designs has designed a floating dry dock. The dry dock is unique in that it is a multipurpose dock. The principal design of the dock is to accommodate a vessel with a maximum displacement of 600 tonnes and a maximum draft of 3.50m. To ensure maximum revenue earning capability, the dock can be split into two separate units of 35m and 25m. This allows greater flexibility and range of vessel that can be dry docked. The dock when joined together to make a 60m dock is shown below, while launching a large catamaran.
