Abstract
The ship building industry is experiencing a wave of new ship technology and design. Historically, ship design has been slow to change. For example, the mono-hull design has been around for centuries. Propulsion has evolved as technology advanced but we see ship owners as very conservative in embracing new advances. In the past 20 years this trend has shifted as new designs begin to appear. This article explores some of these changes and the drivers that are causing this shift. Clearly, as technology advances and uses for ships expand, the ship building industry design is evolving. New issues have come to the fore and have accelerated the design change. These drivers include fuel costs, reduced crewing, speed, security issues, pollution regulations, stealth needs, human factors, safety, geopolitical changes, multi-mission requirements, and acoustic quietness. Examples of military, commercial, and research ships are discussed.
