At NordicSub, we provide professional underwater bottom cleaning, efficiently removing sludge, sediment, sand, and other deposits from the bottom of tanks, basins, and water-filled facilities—without the need to drain the system.
Using specialized equipment and many years of experience, we carry out bottom cleaning quickly, safely, and with minimal disruption to daily operations. This results in reduced downtime, lower maintenance costs, and more efficient asset management.
Why Is Bottom Cleaning Important?
Over time, sludge, sediment, sand, and other particles naturally accumulate at the bottom of water tanks, basins, and technical installations.
These deposits can lead to:
- Reduced water capacity
- Deteriorated water quality
- Increased strain on pumps and technical equipment
- Higher maintenance costs
- Risk of operational disruptions
- Shorter service life of the facility
Regular bottom cleaning is therefore an essential part of an effective maintenance strategy.
Bottom Cleaning Without Operational Downtime
Traditionally, bottom cleaning has often required tanks or basins to be drained, resulting in lengthy shutdowns and significant costs.
NordicSub offers a more efficient solution.
We perform underwater bottom cleaning, allowing many facilities to remain fully operational throughout the cleaning process.
This provides:
- No unnecessary draining
- Minimal impact on production
- Reduced downtime
- Faster maintenance
- Lower overall costs
Where Can Bottom Cleaning Be Performed?
NordicSub provides professional bottom cleaning for a wide range of facilities, including:
- Water storage tanks
- Drinking water reservoirs
- Industrial basins
- Concrete basins
- Fire water reservoirs
- Cooling water systems
- Pump stations
- Harbor basins
- Process and technological facilities
- Industrial tanks and containers
- Other water-filled structures
Professional Equipment – Efficient Results
Using professional underwater suction equipment, we effectively remove sludge, sediment, and other deposits from the bottom without damaging the structure.
Depending on the project, the work can also be combined with:
- Underwater inspections
- ROV inspections
- Mini ROV inspections
- Photo and video documentation
- Ultrasonic thickness measurements
- Visual condition assessments
This provides customers with a complete overview of the facility’s condition and any maintenance requirements.
