Japan’s Mitsui O.S.K. Lines (MOL) has teamed up with Fujitsu Laboratories, and Tokyo University of Marine Science and Technology 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.
The actual voyage data provided by MOL included information such as speed, fuel consumption, main engine rpm, wind direction, wind speed, recorded from October 12, 2015 to December 13, 2015.
                                 

Results of verification
  • Could estimate vessel speed with about a 1.4% allowance, and fuel consumption with an allowance of about 0.8%, based on the above-mentioned method.
  • The following graphs show time-series results of actual measured values of vessel speed and estimated values. Verification confirmed that actual measured values and estimated values are almost the same.

The introduction of autonomous ships, often described as the next step for the maritime industry, is looming as projects have already been launched to make the smart ship concept a reality. One of the examples is the construction of  the world’s first  electric and autonomous containership, Yara Birkeland, which is expected to start autonomous operation in 2019. Numerous benefits of autonomous ships have been identified including lower costs, more efficient use of space in ship design, more efficient use of fuel and lower risk of human error on board, which has been the main cause of accidents at sea. However, the smart ship revolution brings a myriad of challenges that are yet to be resolved, aside to technological hurdles. These involve resolving the issue of navigational safety, protection from cyber threats and creation of a major incentive for owners and operators to invest in autonomous ships before they can become mainstream.

Autonomous ship navigation study begins

BMT’s Rembrandt simulator will be combined with ASV Global’s autonomous vessel control simulator A group of UK-based companies has started a new £1.2M (US$1.6M) research project to investigate how autonomous vessels could co-exist with manned ships. BMT has teamed up with ASV Global and Deimos Space UK for the Shared Waterspace Autonomous Navigation by Satellite (Swans) project. With funding from Innovate UK these companies will investigate how autonomous surface vessels (ASVs) can use existing and future satellite capabilities for collision avoidance and communications. This is particularly focused on autonomous vessels operating beyond the horizon of shore and in congested maritime traffic, BMT managing director Phil Thompson explained, adding that the few autonomous vessels already developed use the global automatic identification system (AIS) for collision avoidance. “But they remain at risk of colliding with vessels or objects not using AIS,” he said in a statement...

Usage of ECDIS - Not as anticipated - A report

ECDIS Not Being Used as Anticipated The U.K. Marine Accident Investigation Branch (MAIB) has announced that it is conducting a safety study, in collaboration with the Danish Maritime Accident Investigation Board, to understand why operators are not using ECDIS as envisaged by regulators and the system manufacturers.  The news follows the release of a MAIB investigation report into the grounding of the bulk carrier  Muros . In the early hours of December 3, 2016, the  Muros  ran aground on Haisborough Sand, eight miles off the Norfolk coast.  When  Muros  grounded, she was following a passage plan shown on its electronic chart and display information system (ECDIS). The MAIB investigation found that: • The vessel was following a planned track across Haisborough Sand. The passage plan in the ECDIS had been revised by the second officer less than three hours before the grounding and it had not been seen or approved by the master. ...
