Abstract-In this work we demonstrate the use of co-simulation technology in the maritime industry through four relevant examples of applications based on the outcome of the knowledgebuilding project Virtual Prototyping of Maritime Systems and Operations (ViProMa). Increasing computational capabilities opens for extended use of simulators in the design processes. Even complex systems can now be analyzed at an early stage of the design process and even in real time using distributed simulation technology. We conduct an assessment of the need for co-simulation technology in the industry, present a short background in co-simulation technology, and provide a short summary of the major findings and deliverables in the ViProMa project (http://viproma.no). The four case studies presented in this work pinpoint different advantages of using co-simulations in the industry, such as combining different modeling and simulation tools, improving collaboration without revealing sensitive information by using black-box models, testing conceptual designs in a fast and consistent manner before initiating building processes, and verifying the interplay between hardware and software in the simulation environment in hardware in the loop (HIL) tests. All the case studies are simulated using the open source co-simulation software Coral developed in the project, using the Functional Mock-up Interface (FMI) standard, and the co-simulation software can be downloaded from the project's web site.

Workspace computation and visualisation is one of the most important criteria in offshore crane design in terms of geometry dimensioning, installation feasibility and operational performance evaluation. This paper presents a numerical method for the computation and visualisation of the workspace of offshore cranes. The Working Load Limit (WLL) and the Safe Working Load (SWL) can be automatically determined. A threedimensional (3D) rectangular grid of voxels is used to describe the properties of the workspace. Firstly, a number of joint configurations are generated by using the Monte Carlo method, which are then mapped from joint to Cartesian space using forward kinematics (FK). The bounding box of the workspace is then derived from these points, and the voxels are distributed on planes inside the box. The method distinguishes voxels by whether they are reachable and if they are on the workspace boundary. The output of the method is an approximation of the workspace volume and point clouds depicting both the reachable space and the boundary of the workspace. Using a third-party software that can work with point clouds, such like MeshLab, a 3D mesh of the workspace can be obtained. A more in-depth description and the pseudo-code of the presented method are presented. As a case study, the workspace of a common type of offshore crane, with three rotational joints, is computed with the proposed method.

“…The multi-level electricity grid with photovoltaic systems [13] and the distributed engine control system [9] are effectively simulated using a co-simulation framework. The virtual prototyping of marine systems using co-simulation is studied in [8], [14], [15]. Moreover, the possibility to select different time step and solver for each FMUs according to the subsystem dynamics increases the computational efficiency while simulating a complex system [16].…”

Co-simulation enhances the efficient simulation development even for complex systems reducing time to market and computational effort. This work aims to develop a marine hybrid power system simulator using a co-simulation approach. The subsystems are packed as Functional mock-up units (FMUs) with the standard interface called functional mock-up interface (FMI). The FMUs for major subsystems are generated from the previously developed dynamic system model. However, FMUs developed by the partners are also compatible for the implementation. These FMUs are implemented in an open simulation platform's (OSP's) software Kopl and Co-Sim App to develop a system simulator. The use of a co-simulation framework for realtime virtual testing and various model fidelity implementation is studied. The developed simulator is used for testing the functionalities and operational capabilities of the studied system. It can simulate faster than real-time, thereby enhancing its use for real-time virtual testing applications. Implementing various fidelity FMUs enhances modularity. It also increases the flexibility in an FMU selection based on the simulation objectives, accuracy, and computational effort.
