About Neptune Robotics
Neptune’s remotely operated robots attach to a vessel and use cavitation-based cleaning tools to remove biofouling from vertical and flat hull surfaces. Cameras let operators monitor the process, while specialised equipment reaches propellers, sea chests and other areas that influence drag and vessel performance.
Cleaning and inspection records are stored within a digital hull-care workflow, allowing ship operators to compare condition over time and schedule work during port calls. Neptune provides the robots and trained operating teams as a service across commercial shipping locations.

Events
- 2026-04-20 - Facility Opening - Neptune Robotics invests $12 million in Singapore hull-cleaning factory
The USD 12 million site will expand local robotics and AI research while targeting a fivefold increase in autonomous hull cleanings. Neptune’s cleaning robots remove biofouling at berth or anchorage without damaging protective hull coatings.

Series B funding was led by Granite Asia. The company said the capital will fund R&D, new robotic systems, AI-driven service platforms, and expansion into 20 markets worldwide. Neptune framed the round around scaling robotics-driven vessel cleaning and energy-efficiency services globally.
Source - 2025-09-25 - Partnership - NYK and Neptune Robotics sign hull-cleaning decarbonisation MoU
Signed an MoU with NYK to expand robotic hull cleaning across NYK's global fleet. Neptune said NYK had already been working with the company since 2022, making it one of the earliest adopters of its robotic hull-cleaning system. The agreement extends the relationship from earlier deployments into a broader fleet decarbonisation partnership.

Brought a second workboat into live operation in Singapore, doubling local operational capacity. Neptune said the added capacity supports dual-robot deployment, faster vessel turnaround, and continuous operations in strong currents. The expansion follows sustained demand after the launch of its first Singapore workboat in November 2024.

Relocated to Singapore to support shipowners and operators along Singapore-China shipping routes. Entered the market with a proprietary fleet of six underwater robots and said it was the first company to bring robotic hull-cleaning capabilities to Singapore at scale. Neptune said the move would support cleaning of approximately 800 vessels over the following 12 months in Singapore.
