Accurately estimating vessel performance within 1.5%, aiming to reduce environmental impact

TOKYO - Mitsui O.S.K. Lines, Ltd. (MOL; President & CEO: Junichiro Ikeda) today announced that it teamed up with Fujitsu Laboratories Ltd. (CEO: Shigeru Sasaki, Headquarters: Kawasaki-shi, Kanagawa Prefecture), and Tokyo University of Marine Science and Technology (President: Toshio Takeuchi, Main Campus: Koto-ku, Tokyo) to verify the accuracy of technology to estimate vessel performance at sea by applying Fujitsu’s artificial intelligence (AI) technology, “FUJITSU Human Centric AI Zinrai.”

This project is a part of MOL’s initiative to assess the effectiveness of AI technology, and aims to reduce fuel consumption and vessels’ environmental impact by verifying the accuracy of the technology, using Fujitsu’s AI Technology to estimate vessel performance at sea.

Outline of Accuracy Verification Test

MOL provided actual voyage data collected from MOL fleet in operation to Fujitsu Laboratories, which, along with Tokyo University of Marine Science and Technology, verified the data by using their jointly developed machine learning method.

Detail of actual voyage data provided by MOL

Items: About 30 in all, such as speed, fuel consumption, main engine rpm, wind direction, wind speed, etc.

Period: October 12, 2015 – December 13, 2015

Verification methods

Learned the correlation of each item of operation data using Fujitsu’s unique AI technology and high-dimensional statistics analysis technology, and established the technology that estimates vessel performance.

Estimated the ship speed from the data other than the speed and verified the comparison between that estimated value and actual operation data, in case to assess allowance of speed. This same assessment was also applied to fuel consumption.
