Abstract
The Open Simulation Platform (OSP) is an open-source industry initiative for co-simulation of maritime equipment, systems and entire ships. With steadily increasing complexity due to the increasing use of software in ship systems, and the integration of equipment and systems from many providers, it has become increasingly difficult to design, build, operate and assure ships and other maritime assets. The OSP sets out to change this by providing key tools and working processes for technical systems engineering. This paper presents the OSP background, its key deliverables, and three use cases that demonstrate the benefits of collaborative digital twin simulations
