Integrating propulsion and navigation systems
The SEAOPS project aims to integrate the propulsion and navigation systems in order to reduce the vessel operator’s workload. Simulation tools are used in order to ensure that this works as intended.
Currently, MS Geir is navigated by a captain, either manually or using an autopilot. The autopilot controls the vessel’s course, while the vessel’s speed is controlled by the thrust pitch and rpm levers.
The SEAOPS project will mainly focus on the initial line-setting phase of line-fishing. The control system will optimize the vessel’s course and speed for the long line, and simultaneously minimize fuel consumption as well as wear and tear on the ship’s machinery. The smart selection of propulsion combinator curves during operation will aid in minimizing fuel consumption.
The SEAOPS project entails using DNV’s Open Simulation Platform to test the control systems and involves using different initial scenarios and at the same time a smart scenario generation tool for more precise testing.
The benefits
In terms of this pilot project, the vessel owner is able to test more in a shorter period of time, and to test in a targeted way to find possible errors and improvement areas when using simulation-based testing.
With many vendors using simulators to develop their control systems, DNV believes the project will improve the handling of complex systems with higher degrees of automation or autonomy – and in doing so, better support customers in the maritime and offshore industries.
