Stena Line is running a pilot study of artificial intelligence (AI) technology on board one of its ferries. With technology company Hitachi, an AI-model is being developed that will help predict the most fuel-efficient way to operate a particular vessel on a specific route. If successful it will make an important contribution to Stena Line's sustainability target to reduce fuel consumption by 2.5 percent annually. The model simulates many different scenarios before suggesting the most optimal route and performance setup. With the help of AI, it considers a number of variables, such as currents, weather conditions, shallow water and speed through water, in various combinations which would be impossible to do manually.
