Clean hull biofouling in-water — no dry-docking required. The JT-1-H uses magnetic wheel adhesion for stable grip on curved ship hulls. Remote controlled with zero diver intervention.
Ship hulls accumulate marine biofouling at a predictable rate: 150–300 μm of fouling thickness per month in tropical waters, translating to a 5–15% fuel penalty within 6 months. Traditional hull cleaning requires dry-docking — a $200,000–$500,000 per-vessel event that removes the ship from revenue service for 10–20 days. For offshore platform legs and subsea structures, diver-based cleaning costs $5,000–$15,000 per day with strict depth and duration limits.
The Jingtao Energy JT-1-H eliminates dry-docking for routine hull maintenance. Its magnetic-wheel adhesion system traverses steel hull plates at depths up to 30 meters, while the rotating brush and water jet end-effectors remove biofouling without damaging anti-fouling coatings. A single JT-1-H covers 500–800 m² per hour on flat hull sections — cleaning a Panamax vessel’s underwater hull in a single 8-hour shift — while the ship remains at berth, in ballast, or at anchorage.
| Scenario | Traditional Method | JT-1-H Robot |
|---|---|---|
| Container ship (3,500 m² hull) | Dry-dock: 10 days, $250K+ | At-berth: 8 hours, <$15K |
| FPSO hull (12,000 m²) | Diver team: 14 days, $120K | Robotic: 4 days, <$40K |
| Jacket platform legs (4 legs) | Divers: 3 days, $45K | Robot: 1 day, <$10K |
No depth or duration limits: Divers are restricted to 30–50 m depth with decompression limits of 30–60 minutes. The JT-1-H operates continuously at 30 m with no decompression constraints — tether-powered, no battery swaps, no crew rotation.
Coating-safe cleaning: The JT-1-H’s rotating brush system applies controlled contact pressure calibrated to remove biofouling without stripping anti-fouling paint. Diver-operated brushes frequently over-clean, exposing bare steel and accelerating corrosion.
Documented inspection: Onboard HD cameras record the entire cleaning pass, providing hull condition documentation for classification society surveys and coating warranty claims — a record that diver-based cleaning cannot match.

The JT-1 series includes four variants for different applications. Contact our engineering team for a detailed comparison and recommendation based on your specific operating conditions.
Explore the full series: JT-1 Mini | JT-1-F | JT-1-H | JT-2.
All JT-1 variants share a common technology platform: permanent magnetic wheel adhesion, remote control operation, modular end-effector interface, lightweight aluminum frame, and tether-powered operation with no battery limits. This platform approach ensures consistent performance, simplifies spare parts management, and allows operators to cross-train on multiple variants.
