ClassNK, the Japanese ship classification society, joined Evergreen Marine Corporation, Samsung Heavy Industries and Weathernews in a memorandum signed on 20 August for a real-vessel test in which Samsung's autonomous navigation system controls a commercial ship's speed in real time1. ClassNK will review the method and issue a Statement of Fact, its formal record of what it verified.
Classification societies certify that ships and their systems meet published rules, and insurers and flag states rely on their word. Putting one inside the trial at the design stage moves the measurement out of the vendor's hands, which matters because fuel-saving claims sell navigation systems, and almost every one of them is self-reported.
The scope has firm limits. Evergreen's crew stays aboard, so what gets tested is crewed autonomous navigation, a system trusted with the throttle while people remain on the bridge, rather than an uncrewed voyage2. The release gives no dates, no vessel name and no expected saving, which leaves the trial unfalsifiable until ClassNK publishes.
The regulatory scaffolding for this arrived two months earlier, when the International Maritime Organization's MASS Code entered force on 1 July with its Experience Building framework deferred to December. A code in force with its evidence-gathering arm postponed leaves verified commercial trials as the only record of what these systems actually do at sea.
