The gradual but purposeful shift towards more environmentally-responsible shipping practices is already exerting an influence throughout the maritime industry supply chain. More and more companies are seeking to put CO2 reduction plans in place involving, for example, the transportation of goods via electric and/or fuel-efficient vessels on short-haul, inland-waterway routes as opposed to deploying trucks on extensive road journeys. Figures suggest that the deployment of an autonomous barge could take around 7,500 trucks off the roads each year, resulting in a substantial reduction in emissions and easing traffic congestion.
VIRTUAL PROTOTYPING OF AUTONOMOUS ALGORITHMS AND INTERFACES
Kongsberg Digital’s K-Sim simulation platform enables fast and effective virtual prototyping as well as the testing and improvement of autonomous algorithms as part of the development process. The Norwegian Maritime Directorate defines five levels of autonomy at sea, of which level 4 is when the vessel will be unmanned, but direct or indirect remote control can be implemented from an onshore control center to oversee complex procedures. The simulator may also be used for prediction-based simulation, based on live environmental and ship data. A key benefit here is that scenarios can be initialized quickly and simulated much more rapidly than in real-time in order to provide time-sensitive support on the outcome of commands from the autonomy controller and navigation systems. It can provide route verifications, power/energy consumption predictions, vital information on weather impacts and analyses based on live data derived from onboard sensors.
SHORE CONTROL CENTERS
Autonomous ships will be tightly integrated to control rooms manned on a 24/7 basis, such as those which are currently being built in Norway for the remote monitoring and management of the autonomous vessels. To ensure the highest availability and most efficient running of shore-based control facilities, the K-Sim simulator is also being used to test remote interfaces to control centers.
Kongsberg Digital is fully committed to developing new simulator standards aimed at building total competence, providing trainee shore control operators with the most comprehensive and realistic operational experience possible. Key to this is creating simulated prototypes of shore control centers: interfaces between K-Sim Navigation and real shore control centers will not only allow trainees to understand best practice for interfacing functionality, but will also assist training on all scenarios related to autonomous shipping, including familiarization with fault settings on autonomous navigation systems and dealing with emergencies. Training will also focus on the way shore control center operators interact with VTS center operators to ensure optimal communication and data exchange.
