Not every vessel in Nagoya is a bulk carrier or a container ship. Tugs, pilot boats, workboats, fishing vessels, ferries and smaller coasters also pick up damage below the waterline, and for them a slipway or dry dock can be hard to book. Underwater vessel repair in Nagoya is a practical answer.
Smaller vessels work hard. Tugs push against ships and quays. Workboats touch fenders and mooring structures. Fishing vessels pick up nets and lines. All of these create the risk of dents, cracks, bent propellers and damaged rudders. Because the vessels are small and busy, owners want repairs done fast, with little time lost.
Typical work includes propeller cleaning and polishing, removal of rope and net from the propeller and shaft, replacement of anodes, repair of rudder fittings, patching of small holes, replacement of gratings and strainers, and inspection after contact damage. Many of these jobs take a few hours, and the vessel can return to service the same day.
Small vessels can be repaired at a quay, a pontoon or a mooring. We bring our equipment by boat or van and set up near the vessel. For harbour craft that spend their time on call, we plan around the duty schedule so the vessel is not out when she is needed.
Some vessels are classed and some are not. If the vessel is classed, we follow the society's requirements and prepare reports for the surveyor. If she is not classed, the owner or insurer may still want a clear record of the damage and the repair. We provide video, photographs and a written report in either case.
We start with a short dive to film and measure the damage. This lets the owner decide whether a Diver repair is enough or whether the vessel needs a yard. We explain the options in plain words and do not recommend work that the vessel does not need.
Send us the vessel's name, type, size and the problem. If you have photographs of the damage or the crew's description of the symptoms, add them. We reply with a plan and a price. For repeat customers, we keep a record of previous work on each vessel, so the next job starts from known facts.
Even small vessels may need paperwork. Harbour authorities, insurers and charterers may ask for a record of the repair. We provide a short report with photographs, a description of the work and the date, which can be filed or forwarded. Keeping these records also helps when the vessel is sold, since a buyer likes to see a history of the underwater condition.
For a tug or workboat that has lost its propeller blade, taken a rope in the wheel or struck an obstruction, we can respond quickly. Call with the position and a short description, and we will arrange the earliest dive available.
Q1. Which vessel types do you repair underwater?
Tugs, pilot boats, workboats, fishing vessels, ferries and smaller cargo ships, as well as larger ships.
Q2. How long do typical small-vessel jobs take?
Many jobs, such as propeller cleaning, rope removal or anode replacement, take a few hours, and the vessel can often return to service the same day.
Q3. Is class attendance needed?
Only if the vessel is classed. In that case we follow the society’s requirements. Unclassed vessels still receive a full report for the owner or insurer.
Q4. What do you need to plan a repair?
The vessel name, type, size, location and a description of the problem, with photographs if available.
