OSP status demonstrated at 3rd JIP workshop

Late October 2019 the JIP participants were gathered at DNV headquarters at Høvik for the 3rd JIP workshop. The main topics were to demonstrate the status of the software development, the standard and the JIP use cases and to discuss future use and corresponding requirements to the Open Simulation Platform for collaborative system simulations.

Both the development of Core Simulation Environment (CSE) and the standardization work are progressing according to plan. The CSE v0.5.0 was recently distributed to partners with features such as individual model step size and command line interface to facilitate more efficient simulations for the JIP use cases. The software development is also closely linked with the development of the standard, supporting features for mapping of signals and connection of models defined by the system ontology under development.

Status for the three use cases under development was presented, a brief summary below:

  • For the hybrid ferry case, models from multiple partners are decided upon and the case is currently being configured for simulations with CSE.
  • For the virtual commissioning case a live demo of simulation models and control system software for Dynamic Positioning of a vessel running in closed loop was shown. Next steps are to update simulation models and include multiple control systems to test and verify integrated functionality onboard a costal support vessel.
  • Simulation models of the research vessel Gunnerus are available from previous R&D projects. The use case for operational planning demonstrate how these models are converted to FMUs and run with CSE software. Challenges related to tightly coupled models and co-simulation is an important topic for the next step.

To make a collaborative simulation platform a success, proper mechanisms for protection of intellectual property rights for those supplying models or data to a simulation, as well as ownership to results are essential. DNV presented how solutions for this can be implemented on for the OSP. All partners where engaged in brain-storming sessions aiming to map intended use and corresponding requirements for a future platform. This session together with overall feedback during the workshop provided valuable input to development of the required platform features.
