Emptying and cleaning of tanks

We specialize in cleaning ship tanks and pipes.

At harbor, dock and sea we clean

heavy oil tanks
diesel tanks
ballast water tanks
freshwater tanks

We use efficient vacuum and cleaning equipment to empty and clean tanks, and our versatile equipment offers the right solution for any situation and place.

Emptying and cleaning septic and evac tanks is done with routine. When cleaning freshwater tanks and pipes we also disinfect them. Diesel oil tanks can harbor bacteria that requires total hot steam cleaning and chemical handling to get rid of. We also fetch scrubber waste from ships.

We use our own detergents and warm water when we clean, so less water is used in total.

Bilge cleaning

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.

Our own detergents are specifically designed for these demanding cleaning tasks.

Cleaning of engine rooms, engine shafts and funnels

The cleaning of engine shafts and funnels requires good working methods and excellent workmanship.

Cleaning of engine rooms, engine shafts and funnels regularly is an important part of fire safety. Before cleaning we carefully protect sensitive areas, and after cleaning we remove any remaining water from all levels with a suction unit.

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 blow away paint. Removal of paint on level surfaces is successfully 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 high pressure vacuum truck is a time saving method in repair work.

Cleaning of cargo decks and holds

We quickly and efficiently

clean
disinfect
remove odors, after for example a cargo of fish meal.

The proper cleaning of a sooty main deck on a ro-ro ship by our team often produces the same result as re-painting the deck, while also being much less expensive.

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.
