Japanese shipping giant NYK is scaling up robotic hull cleaning across its global fleet of nearly 800 vessels through a new partnership with Neptune Robotics.

NYK has been testing Neptune’s technology for three years, reporting significant fuel savings and lower carbon emissions. Early trials show that every $1 spent on robotic cleaning generates up to $10 in fuel savings by reducing hull resistance.

As part of the new MOU, NYK is also investing in Neptune’s $52 million Series B funding round to support global expansion, R&D, and AI-driven platforms. The goal: wider access to robotic cleaning services, especially in Japan, and faster adoption across the shipping sector.

Neptune already operates in over 60 ports across China and Singapore — covering 70% of major global trade routes. Its robots can clean a full capesize bulker in just 24 hours, including specialized services that meet Australia and New Zealand’s strict standards.

NYK says the collaboration will not only decarbonize its own fleet but also set an example for the broader maritime industry.
