Rolls Royce to Design Ships - Rolls-Royce has broadened its capability in ship design with the establishment of a new team dedicated to the development of naval ship designs.    It will develop vessels for navies, coast guards and other maritime agencies.    The design team will focus on offshore patrol vessels, survey ships and support vessels, rather than combatants.     They will include variants of the award winning Environship merchant ship concept, including a replenishment ship for refuelling and supplying naval fleets that features a wave piercing bow and hybrid electric propulsion system and is  available in the 9,000 to 25,000 dwt range.
