Owners rarely need the same thing twice. One ship needs a quick look at the waterline, another needs the whole underwater body cleaned before a charter. Our ship hull cleaning service in Nagoya is built in three packages so you can pay for what the ship actually needs.
This is the starting point. A Diver films the Hull with CCTV, wipes a few sample areas and tells you how much fouling is present and what type. You receive a short report with a recommendation. Many owners choose this when they are unsure whether a full cleaning is worth the cost, or when a ship has been idle and nobody knows the state of the plating.
Some areas matter far more than others. The propeller, the sea chests, the rudder, the waterline and the bow thruster grating influence performance and cooling most. In a partial cleaning we focus on these places, usually in a few hours. It suits ships on short port calls and ships that were cleaned recently but have picked up growth in the most exposed spots.
Here the Diver team cleans the whole underwater body, section by section, from the waterline to the keel line. A ship of 180 to 200 m normally needs 1 to 2 days, and larger ships need more divers or more time. This is the right choice before a long voyage in warm water, after a long idle period, or when an inspection shows heavy growth over the flat bottom.
Think about three things: how long since the last cleaning, how long the ship will stay in Nagoya, and what the next voyage looks like. If the stay is short, partial cleaning is often the best use of the time. If you are not sure, start with package one. The video will show what is needed and the price of the next step can be agreed on the spot.
The method depends on the paint. Soft brushes suit most antifouling coatings and silicone foul-release paints. Heavier tools are used only where the coating can take them, and where the fouling cannot be removed otherwise. We ask for the coating data sheet when it is available and begin with a small test area if the paint type is unknown.
Every package ends with video and a report. The report lists areas cleaned, the type of fouling found, the method and any damage seen. A Hull that was cleaned and filmed in Nagoya gives the technical manager something to compare with next time. Our team holds ClassNK and ABS certification, and the reports are laid out so they can be passed on to class, charterers or management without rewriting.
Many owners add small jobs to the cleaning: sea chest grating cleaning, anode checks, a rope-guard inspection or a short propeller polish. These are priced separately, and because the team is already on site, they usually cost less than a second call.
Q1. What are the three hull cleaning packages?
Package one is an inspection with light cleaning, package two is a partial cleaning of key areas such as the propeller and sea chests, and package three is a full cleaning of the whole underwater Hull.
Q2. How long does a full cleaning of a 180 to 200 m ship take?
Normally 1 to 2 days, depending on how heavy the fouling is and how many divers are used.
Q3. Which areas are included in a partial cleaning?
The propeller, sea chests, rudder, waterline and bow thruster grating, usually completed in a few hours.
Q4. What is delivered with each package?
Time-stamped CCTV video, photographs and a written report listing the areas cleaned, the type of fouling, the method and any damage found.
