JAPANESE PARTNERS DEMONSTRATE AUTONOMOUS SHIPPING TECHNOLOGY

Friday, July 12, 2019 

Mitsui OSK Lines (MOL), Mitsui E&S Shipbuilding, Tokyo University of Marine Science and Technology (TUMST), and Akishima Laboratories (Mitsui Zosen) have announced results of auto-berthing trials undertaken earllier this year.

The test used the TUMST training ship Shioji Maru for the joint demonstration project related to the safety of vessels' auto berthing and un-berthing. The project was selected for Japan's Ministry of Land, Infrastructure, Transportation and Tourism (MLIT)'s FY2018 autonomous vessel demonstration project.

The project team completed a total of 54 auto berthing operations using a virtual pier set on the open water, and gained useful data for R&D on auto berthing systems. Before conducting the test, the team formulated the ship operation plan, test guidelines, and criteria for canceling the operation ahead of time due to safety concerns, at the same time completing a thorough safety assessment under various phenomena by using the simulation environment.

The team plans a demonstration test with a large-size coastal ferry in FY2019 after substantially examining the development of ship operation control system and test methods to address the following issues:

  • Realisation of auto berthing control in consideration of vessel speed, course, and distance with sufficient safety margin, without making seafarers recognize risk.
  • Realisation of appropriate manoeuvring control in consideration of the large-size ferry’s manoeuvring performance characteristics.
  • Determination of definite criteria for making decisions of continue/stop on auto operation in consideration of events such as machinery and equipment failures that occur during auto operations and other phenomena such as sudden changes in surrounding environmental conditions.
  • Determination of guidelines for the transition of ship operation from the system to the crew after the cancellation of the automatic operation considering safety and situation.

MES-S, MOL, TUMST, and Akishima Laboratory will contribute to the achievement of safe, reliable ocean transportation through activities including the auto berthing and un-berthing demonstration project and other efforts to promote the development of autonomous vessels.
