The Naval Tanker and Amphibious vessel are traditionally two mission specific ship types. However are there real cost effective benefits in combining two important military assets into a single platform? Many navies are beginning to think so, as demonstrated in the Dutch Joint Support Ship and similar programs in Norway, Sweden, Canada and New Zealand to name a few. Rolls Royce has recent experience in designing this new ship type which combines Replenishment at Sea capability with the Roll on - Roll off capability needed for amphibious support. Other capabilities of such a vessel include aviation, hospital & humanitarian support, command and control, ammunition storage & even dynamic positioning has been considered. Some key design drivers include fuel carrying capacity, fuel type, aviation capability, number of Roll on - Roll off lane meters needed, hospital size, intended ships company, provision for landing craft and ammunition storage. The ships operational profile is also critical in designing an optimum propulsion system. In particular top speed requirements will influence hull form selection which will drive vessel particulars, installed power and ultimately propulsion selection. Future MARPOL environmental regulations and vessel environmental operational requirements are also considered key design drivers. Of great importance is the integration of various deck systems to achieve a harmonious ship design that is both cost effective but also provides a smooth logistical flow of stores throughout the vessel, ensuring good operability of ship functions. What are the cost drivers? Combining two naval platforms into one must be justifiable. A thorough analysis is conducted.
