AI-based project to optimize vessel performance forecasting concludes testing
Maritime technology company Yara Marine Technologies, Artificial Intelligence (AI) application developers Molflow, and Chalmers University of Technology and social science specialists from Halmstad University and Gothenburg University have collaborated over 3 years to develop and trial an AI-based semi-autonomous voyage planning system. Initiated in August 2020, the Via Kaizen project explores how AI and machine learning can enable more energy-efficient voyage planning for ship operators.
Funded by the Swedish Transport Administration Trafikverket, the project utilized pre-existing tools, to enable a higher degree of digitalization and automation in vessel operations. These included Yara Marine’s propulsion optimization system FuelOpt and performance management and vessel data reporting tool Fleet Analytics, as well as Molflow’s vessel modelling system Slipstream. Existing work practices onboard and user needs were analyzed during the design process to ensure the technology facilitated processes and decisions with the greatest impact on energy efficiency.
The resulting system was trialed onboard two vessels, a PCTC car carrier operated by UECC and a Rederiet Stenersen product tanker. The wide-ranging results indicated successful energy efficiency optimization based on estimated time of arrival (ETA), with one of the two trial vessels opting to continue using the system.
The Via Kaizen project demonstrated that incorporating machine-learning algorithms for improved predictive modelling of ship propulsion power can result in more accurate performance forecasting and optimization. It also evidenced the necessity of constructive collaboration between technology developers and users, as well as between ship operators and their customers.
Throughout the trials, crew played a key role in determining the success of energy efficient voyages. This shows the necessity giving ship crews and management every opportunity to engage with, understand and embrace the value of AI-powered ship operation support technology in assisting daily operations onboard and ashore.
Following the conclusion of this project, additional funding has been secured from the Swedish innovation agency Vinnova to further explore a selection of its findings.
