Green Tech: Rise of the [Hull Clening] Robots
hull management, where coatings, monitoring and cleaning technologies work together as part of a lifecycle strategy.While Greensea IQ and Jotun remain among the most recognized players in the field, a growing ecosystem of robotics companies is bringing new approaches to hull maintenance.Singapore-based Neptune Robotics is focusing on operational flexibility. Its robotic systems can operate in turbid water, at night and in constrained port environments—conditions that often challenge traditional diver-based cleaning operations. The company’s cavitation-jet technology removes fouling while minimizing
Application Note: Pressure Relief Valves and Purge Ports
the interior PRV seal is impossible to inspect directly. A leaky PRV seal could be found if a vacuum leak test were performed from a separate purge port. End-users are otherwise left to hope, luck, chance, and wishful thinking. “It’s probably OK” are not words to speak when facing King Neptune. Davy Jones keeps what he covets. You need to know for sure. An internal pressure sensor connected to an external read-out is another solid means to confirm seal integrity.Suggestions from motivated sales personnel that a PRV can perform a dual use play into this problem. One PRV manufacturer offers

used in underwater inspection, monitoring, and security applications.“Sound Metrics brings highly differentiated technology and a strong reputation for innovation in underwater imaging,” said Mike Read, Chief Executive Officer of OceanSight. “Together with Ocean Floor Geophysics and Neptune Sonar, Sound Metrics strengthens OceanSight’s ability to provide a comprehensive suite of subsea sensing and imaging solutions that help customers better understand and operate in challenging underwater environments.”Hampidjan Advant, a specialist in crafting premium HMPE and Aramid
Money Pours in for Hull Cleaning Technology
.3 million) Series A round to finance its autonomous underwater robots for cleaning and inspecting hulls. The new capital will help the company scale its manufacturing, establish more international service hubs, and evolve its robotic systems to accommodate larger shipping vessel classes.In September, Neptune Robotics raised $52 million for its underwater robots which it claims cleans hulls 3-5 times faster than divers. Its systems can clean full draft Capesize vessels in under 24 hours, operating day and night in clear or murky waters and even in 4-knot strong currents.In October, Yanmar Holdings and
NYK, Neptune Ink Robotic Hull Cleaning Deal in Maritime Decarbonization Push
Nippon Yusen Kabushiki Kaisha (NYK Line), one of the world’s largest shipping companies, has expanded its partnership with Neptune Robotics to scale up robotic hull cleaning across its global fleet in a move expected to deliver major fuel savings and accelerates maritime decarbonization.NYK has worked with Neptune since 2022, making it one of the earliest adopters of Neptune’s robotic hull cleaning. From earlier deployments, Neptune’s robots delivered up to 10 times fuel savings compared to cleaning costs, with significant reductions in fuel use and emissions, according to NYK.

MacArtney to Equip N-Sea’s Altera CLV Newbuild
Q1 2026."By joining forces with SCA and Enersea, we’ve brought together the best of three worlds—innovative technology, smart engineering, and robust execution,” said Mike Welling, Business Development Manager at MacArtney Offshore Wind Solutions. Altera CLV is being built by Neptune Marine and will transfer to The Netherlands in Q4 2025 for fitting and commissioning in Q2 2026. The DP2 vessel will be dual fuel (methanol) prepared, equipped with a 25t offshore knuckle boom crane, mooring system and can accommodate up to 99 people
TDI-Brooks Completes Trinidad Geotechnical Project
coring project for Geohidra. This operation was conducted from the DRAGON Field to the HIBISCUS platform off the coast of Venezuela and Trinidad aboard the DONA JOSE II (DJII). Throughout this campaign, TDI-Brooks performed a total of eighteen (18) Cone Penetration Tests (CPTs) utilizing their Neptune 3,000 miniature coiled rod CPT system, achieving penetration depths between 3.25 and 6.25 meters in water depths of 130 to 150 meters. Additionally, eighteen (18) Box Core samples and eighteen Cyclic Mini T-Bar tests on Box Core samples were completed
