Mitsui to use AI technology to assess vessel performance at sea

LBR Staff Writer Published 10 November 2017

Japanese transport firm Mitsui O.S.K. Lines (MOL) has collaborated with Fujitsu Laboratories and Tokyo University of Marine Science and Technology to use artificial intelligence (AI) technology for evaluating the vessel performance at sea.

The partnership will use the Fujitsu Human Centric AI Zinrai AI technology to estimate vessel speed and fuel consumption at sea.

Part of the Ishin Next-MOL Smart Ship Project, the project evaluates the effectiveness of AI technology and, helping to enhance operating safety and reduce environmental impact through reduction of fuel consumption.

MOL offered actual voyage data collected from its operational fleet to Fujitsu and Tokyo University of Marine Science and Technology. The data was verified by using their jointly developed machine learning method.

MOL provided data included vessel’s speed, fuel consumption, main engine rpm, wind direction, wind speed and others.

Fujitsu AI technology and high-dimensional statistics analysis technology have been used to learn the correlation of each item of operational data, helping to estimate the vessel performance.

The estimation included the ship speed from the data other than the speed and verified the comparison between that estimated value and actual operation data, enabling to evaluate allowance of speed.

The same evaluation method was also applied to fuel consumption.

According to MOL, the evaluation method could estimate vessel speed with about a 1.4% allowance and fuel consumption with an allowance of about 0.8%.

Part of the Ishin Next-MOL Smart Ship Project, the project evaluates the effectiveness of AI technology and, helping to enhance operating safety and reduce environmental impact through reduction of fuel consumption.
