NYK has conducted a claimed ' world first' Maritime Autonomous Surface Ships (MASS) trial performed in accordance with the IMO’s Interim Guidelines for MASS trials, as a move towards safer operations and a reduction in crew workload.

Iris Leader, a large NYK-operated PCTC of 70,826 gt, was navigated day and night using the Sherpa System for Real ship (SSR) navigation system during the period from 14 to 17 September from Xinsha, China, to the port of Nagoya, Japan, and then from the port of Nagoya to the port of Yokohama, Japan, from 19 to 20 September. Crew performed typical duties during the navigations, which included Japan’s coastal area but excluded bays.

During the trial, the SSR’s performance in actual sea conditions was monitored as it collected information on environmental conditions around the ship from existing navigational devices, calculated collision risk, automatically determined optimal routes and speeds that were safe and economical, and then automatically navigated the ship. Using data and experience gained through this trial but not obtainable through onshore simulators, NYK was able to ensure the feasibility of the SSR and its benefit for safe and optimal operations. This trial was a big step toward realising NYK’s goal of manned autonomous ships.

NYK will analyse the data and continue to develop the SSR into a more advanced navigation-support system by making adjustments to the difference between the optimal course derived by the program and that determined by professional human judgment.

The SSR verified by the trial will be applied to future coastal ships, which currently face serious crew shortages. NYK believes SSR can become a basic technology for remote and unmanned navigation, contributing to social issues through business that embodies NYK’s 'Bringing value to life' mission.

The NYK Group says it will accelerate its digitalisation efforts based on the company’s medium-term management plan 'Staying Ahead 2022 with Digitalization and Green', and will conduct development and demonstration tests of advanced operational support technologies to realize manned autonomous ships.

The SSR system navigates a vessel by calculating optimal routes based on environmental conditions, to support actual vessel operation. By incorporating knowledge and perceptions by experienced captains, a program will be established as one of MASS technologies.
