At a recent online webinar, the Open Simulation Platform (OSP) joint industry project (JIP) announced the results of its two-year project run and the intention to transition into an open source community. The project, which attracted some twenty partners, including founding participants DNV GL, Rolls-Royce Commercial Marine (now Kongsberg Maritime CM), SINTEF, and NTNU, was focussed on the co-simulation of maritime equipment, systems and ships, with the goal of enabling cross-organizational collaboration.
