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 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.
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.
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.
​Cleaning up oil spills
We have versatile specialist equipment at our disposal for the cleaning of oil spills:
​
-
hot water cleaners
-
mobile steam-heating coils for heating heavy oil
-
vacuum units and trailers equipped with heating coils
-
trailers
-
other vacuum and pumping equipment for handling very stiff oil
Cleaning services for properties and
construction sites
In construction, renovation and real estate maintenance, there are situations where Langh’s specialist skills are warmly recommended. For example, removal of earth and insulation materials, mold eradication and handling of dangerous materials are taken care of quickly and effectively with our specialist tools. We are also experienced with the prevention of further damage after fires.
​​
Construction and insurance companies have long used Langh’s services. Our skills are equally available for use by both housing organisations and private real estate owners. Typical projects in small housing areas are unblocking of drains and vacuuming of base floor and roof cavities.
​
We offer our cleaning services with quick response time in the southern part of Finland.
Hydrodemolition of bridge and concrete structures
​
We use high pressure water to break concrete and other porous material with accuracy and good workmanship. With hydrodemolition, damaged parts can be removed without damaging healthy structures. The pressure levels of our Ultra High Pressure cleaning equipment are 1000 bar, 2 500 bar and 3 000 bar.
​​
The main advantage of hydrodemolition is that the remaining steel comes up unbroken and clean with a surface that makes it easier to work the concrete further. With hydrodemolition the end result is always of high quality.
Water jet cutting of concrete and steel
With water jet cutting, concrete and steel can be cut without vibration and sparks. This method is highly recommended for tasks such as making holes to tanks, floors and many fire-sensitive targets. Water jet cutting has been utilized in, for example, elevator renovations. In our opinion water jet cutting is preferable to diamond cutting as its more agile, allowing customer needs to be taken into consideration.
​
In special locations, such as ship tanks, utilizing water jet cutting means the space does not need to be gas free. Thanks to water jet cutting and our skilled and punctual staff the temperature of the location will not rise.
Removal of plaster and coating
​
Removal of plaster and coating can be achieved with two methods:
​
-
High Pressure cleaning
-
Wet Sandblasting
​
The removal of paint on level surfaces is successfully carried out with a surface cleaner which can be connected directly to a vacuum truck.
​
​
​
Facade renovations
High-pressure cleaning with a suitable detergent is a noteworthy, dust-free alternative when renovating facades.
​
Painted surfaces (even those that contain asbestos), plaster and other facade coatings are removed efficiently without irritating dust and sand emissions.
​
Removing graffiti
Removing graffiti and daub is done with a hot water cleaner and suitable detergent. Detergent is selected in accordance with the surface material.
Rinsing and imaging of pipe systems
We unblock, drain and rinse pipe systems and sewers with skill and accuracy, and our video camera equipment can be used to determine the condition of the target beforehand.
We also empty different kinds of wells, such as sand separation wells, storm water drains, oil traps, grease traps and cesspools swiftly and according to your needs.
Removal of soil and insulating mass
High-power vacuuming is an efficient method for removing soil and insulating mass. When renovating a floor/crawl space, removing soil and insulating mass often becomes relevant. In such cases, calling our high-power vacuum truck to aid is the best idea — especially if you're dealing with sand, concrete waste or crushed brick. The substance to be vacuumed can also be crushed at site, so you don’t need to wonder whether some pieces of the waste are too large for our truck to handle. Vacuuming and blowing shingle, macadam and gravel is no news to us. Vacuuming sawdust and wool is also handy with our high-power vacuum truck, as it prevents dust from being blown all over.
​
Vacuuming sawdust, shavings and straws from the roofs of old buildings is done dust free and swiftly with our high-power vacuum truck.
Prevention of further damage
After initial damage prevention and drying we will complete the further damage clean up. If necessary, we will arrange power generators and heat to the damaged areas.
​
For more than 30 years, we have carried out cleaning work and further damage prevention after fires. We are skilled, fast and cost-efficient in preventing further damage!
​
Drying and heating
Thanks to our effective drying container we can dry out areas and keep them warm no matter how cold it is outside. This helps prevent freezing damage, which could cause significant expenses.
