SHIPS HULL AND MARITIME INFRASTRUCTURES
UNDER WATER CLEANING

WHY? HOW?

1. WHY Underwater Cleaning?

 

- The most effective way to save both money and the environment -

Today underwater ship hull cleaning, thoroughly and efficiently done on an industrial basis and on a suitable hull coating, is the answer to reduce fuel costs, cut GHG emissions, prevent the spread of non-indigenous species and avoid marine chemical pollution.
- We perform ships' cleaning in VANUATU and NEW CALEDONIA for domestic fleet only -

2. HOW to clean underwater?

ABC Diving offers complete cleaning in hours for Maritime Infrastructures and ship hulls, by using:

Hydraulic BRUSH CLEANING MACHINE

- PAINT SAFE: Equipment approved for Hull cleaning of SPC self polishing coatings, Silicone based coatings, Epoxy based coatings -

We operate a large line of Armada's UNDERWATER HULL CLEANING BRUSHES (meet & exceed Navy standards) http://www.armadahull.com/hullcleanersp.htm

Here is a sample of the brushes used for cleaning (http://www.armadahull.com/barnaclep.php):


Different brushes and grits are available depending on the hull surface growth and condition

Theses both brushes are for removal of barnacles and other encrusted sea growth from steel, concrete and wood pilings, seawalls, bridge supports, bulkheads and ships.


Both brushes above are for removal of barnacles and other encrusted sea growth from steel, concrete and wood pilings, seawalls, bridge supports, bulkheads and ships.

3. WATER BLASTING

Water blaster with specific lances and nozzles are very efficient above and below the water line.

PAINT SAFE, underwater blasting will clean efficiently by removing substances from PILLARS, WATERSIDES, SHIPS (hull, "niche" areas, props, anodes) and other underwater surfaces.

4. HIGH PRESSURE WATER JETTING

High Pressure Water Jetting provides the most effective underwater cleaning technique. The operation is commonly called "JETTING".

It removes coatings and rust, and runs with a single operator.

Removal of the marine growth alone is normally adequate for close visual inspection, then BRUSHES are efficient; but Critical NDT inspection, however, requires the removal from the metal surface of everything including paint, coatings, scale, etc. so as to leave a bright shiny metal surface, then JETTING is efficient

SAFETY: The high pressure water jetting gun is a potentially dangerous tool and needs handling with great care. All our divers using such equipment are trained in its use.
The following precautions should be observed by divers:

  1. At no time should there more tha one diver working in an area where jetting is taking place
  2. The signal to start the high pressure water supply should only be given by the diver when he is ready to start jetting
  3. Under no circumstances should the diver adjust the operating trigger in order to maintain an open position
  4. A strong guard should be fitted around the trigger to prevent inadvertent operation
  5. The diving supervisor should always be in direct contact with the technician running the pumps who should be standing by his pump whilst it is running. It is imperative that clear communications exist at all times between the supervisor, the pump and the diver.
