Since many different design and engineering applications are used in shipbuilding, the exchange of product information presents big challenges. The very nature of shipbuilding (one-off or small series) along with the involvement of a large number of systems integrators, subcontractors and suppliers mean an enormous exchange of technical, commercial and logistical information among all parties involved. The difficulty in proper digital communication between systems of different shipyards, sometimes inside the same shipyard, remains a serious hindrance to increased competitiveness. Concurrent engineering and globalization has made it imperative to achieve efficient exchange of product and process information using the available infrastructure and bandwidth. To overcome the challenges in data exchange between different software systems, many solutions have been proposed like converters between CAD systems, using a standard exchange format like STEP, etc. This paper proposes using the industry standard light-weight, neutral format JT as a data exchange standard in shipbuilding.
