Directions for use
Direct injection method - for tank cleaning machines
The dose rate should be between 0.1-0.2% i.e.1-2 litres per ton wash water.
Recirculation method - for tank cleaning machines
It is advised to use a solution of 0.1-0.2% i.e. 1-2 litres per ton wash water mixed in the tank to be cleaned.
Dose rates and results will vary depending on contamination, the temperature of the cleaning solution, and number of tanks to be cleaned with the solution. Best results are obtained when water is heated to a temperature between 65-80°C.
UNITOR™ Seaclean Plus™ can be sprayed neat onto tank surfaces to be cleaned. The contact time should be at least 30 minutes. Bulkheads/walls can be washed down by use of tank washing machines or high pressure cleaning machines. The best result is achieved with hot water between 60-80°C. Slops should be constantly stripped from the tank and transferred to a holding tank or pumped ashore to slop tanks.
Rock and Roll method
- Cleaning of double bottom tanks during voyages.
- Heat the remaining fuel in the tank, trimming the vessel as required to assist in stripping tank.
- Flush tank with sea water, stripping constantly.
- After flushing, ensure all suction and discharge valves in the engine room are closed.
- Dose tank with UNITOR™ Seaclean Plus™ through the sounding pipe or manhole between 0.5 - 1 litre per ton of water, for 75-80% of capacity of tank to be cleaned.
- Fill tank to 25% capacity with sea water, raise the temperature up to 60°C and maintain this for 24 hours.
- Top up tank to 75-80% capacity with sea water and continue to heat for 48-72 hours.
- Discharge and strip tank. Fill to 50-60% capacity with sea water and allow 2 hours rinsing time.
- Discharge tank and strip, flushing tank with sea water for 2 hours, stripping continuously. When completed, inspect tank to ascertain if second cleaning is required. If so:
- Add second dose of UNITOR™ Seaclean Plus™, fill tank to 75-80% capacity with sea water and raise the temperature to 60°C maximum. Maintain this for 48-72 hours. In calm seas recirculate the solution in tank as long as possible.
- Discharge and strip tank, flush with sea water, stripping continuously for 2 hours. To gas-free, fill tank with sea water to overflow through vents and sounding pipes, discharge and strip completely.
