Bilge Cleaning with the Suction Power of a Vacuum Truck

Tank and bilge cleaning is one of Hans Langh Cleaning Services' areas of expertise, and perhaps the most significant and busy part of our ship services. Our customers place special value on our ability to carry out bilge and tank cleaning while the ship is at sea.

We have developed a compact suction device for bilge and tank cleaning. It is also suitable for the cramped engine room, but nevertheless offers the suction power of a normal vacuum truck!

When cleaning a bilge we truly vacuum and wash away all oil and dirt instead of just hiding it.

Tank Cleaning

We specialize in cleaning ship tanks and pipes. We clean heavy oil tanks and diesel tanks, as well as ballast and freshwater tanks. We carry out cleaning work in harbors, at shipyards and even at sea.

We also empty and clean septic tanks and evac tanks, as well as fetch scrubber waste from ships. When cleaning freshwater tanks and pipes, we also disinfect them.

Engine Room, Engine Shaft and Funnel Cleaning

Periodic cleaning of engine shafts, chimneys and engine rooms is an important part of fire safety. Before cleaning, we ensure sensitive areas are protected, and after cleaning we remove water from every level with a suction unit.

Cargo Hold and Deck Cleaning

We quickly and efficiently clean, disinfect and deodorize ship cargo holds and decks.

Thorough cleaning of a sooty deck on a ro-ro vessel produces a better result than re-painting, as applying a new coat of paint on a dirty surface often leads to poor adhesion, causing the paint to flake off easily.

Cleaning the Sides and Decks of a Ship

We use high-pressure cleaning devices to clean the sides and decks of ships. High-pressure cleaning is a highly effective cleaning method.

Paint Removal

We use high pressure equipment with a range of 500 – 3,000 bar to blast away paint. Removal of paint on level surfaces can be carried out with a surface cleaner which can be directly connected to a vacuum truck.

Vacuuming Sandblasting Sand

High-power vacuuming of sandblasting sand with a high-pressure vacuum truck saves time during repair work.

Prevention of Further Damages

Over the years we have handled the cleaning of engine rooms after fires or after the ship has run aground. The majority of these assignments come from abroad, and we have established an international reputation for being a leading company in the field.

In these cases valuable assets are often at stake, and the nearest help is not always the best help! Fast and professional action contains the damage, decreases repair time and saves on expenses.

Fast Cleaning Minimizes Damages

During a fire in the engine room, large quantities of chlorides are released from the engine room’s cable compound. These chlorides combine with the steam in the air and form aggressive acids.

In such cases, all machined surfaces (including the insides of machines and equipment) and electronics in particular are at risk.

Following a fire, it is important to determine the level of chloride contamination in different parts of the engine room and follow up with a plan of action. A quick test using the silver nitrate method can be conducted, and accurate numerical values can be determined more precisely by using measuring equipment. In situations following engine room fires and ships running aground, the protection of machinery and equipment from corrosion is of primary importance.

For example, in situations where the engine room has flooded, pumping should not begin until a conservation team is on site. If necessary, we can take care of the machines until they are back up and running.
