DESCRIPTION
TANK SUPER CLEANER is a heavy duty, highly concentrated tank cleaner with strong emulsifying action and low odour.
TANK SUPER CLEANER has a high flash point and is IMO-approved. Only cleaners registered in Annex10 of IMO’s MEPC.2/ Circular can be used and disposed of at sea for cargo tank cleaning, when the cargo residue slops are disposable at sea.
APPLICATION
TANK SUPER CLEANER has a wide range of applications. It is suitable for cleaning double bottom, deep tanks, cargo tanks and bilges or generally fuel oil storage tanks. TANK SUPER CLEANER is ideal for removing oily pet coke. It may also be used for engine rooms and/or deck cleaning and degreasing.
USE AND DOSING
Precleaning tanks with high pressure warm water is highly recommended since large deposits of oil or other residues in the tank must be removed to ensure an effective cleaning operation. TANK SUPER CLEANER can be applied using all conventional mechanical or manual means. The amount and nature of contamination, the available heating facilities, the degree of cleaning required and the capacity of tanks to be cleaned must be taken into consideration when determining which dosage rate to use. Best results are achieved in temperatures between 60 to 80°C.
Instructions and dosages are based on experience and are meant only as a guide, since circumstances for each tank cleaning operation vary. They are not intended to interfere with the judgment of the vessel’s responsible personnel.
CLEANING PROCEDURES
A. Direct Injection Method
Introduce a solution 0.1-2.0% of TANK SUPER CLEANER directly into the tank wash water line by means of an eductor or a small pump. The tank should be stripped continuously while washing. Rinse the tank with ambient temperature water immediately.
B. Recirculation Method
It is recommended to use a solution of seawater and TANK SUPER CLEANER for this method. The total quantity of product should be between 0.5 and 3.0%, i.e. 5-30 litres per ton wash water. Care should be taken, as, under extreme conditions, the concentration should be considerably increased.
The procedure is the same as the direct injection method except for the fact that the tanks being washed are stripped back to the recirculation tank. Care should be taken to observe when the solution becomes saturated.
C. Spot Cleaning
TANK SUPER CLEANER can be sprayed neat onto tank surfaces to be cleaned. Optimum results are achieved when hot water (between 60 to 80°C) is used and when contact time is at least 30 minutes. Bulkheads/walls can be washed down by the use of tank washing machines or high pressure cleaning machines.
D. Rock & Roll Method
Effective for cleaning double bottom and deep tanks at sea. The recommended dosage rate is between 0.1-0.3% of TANK SUPER CLEANER. Minimum recommended time to complete cleaning operation is five (5) days.
1. Fill the tank with the proper amount of TANK SUPER CLEANER for the first cleaning step through the sounding/vent pipe using the appropriate dosage scheme outlined in Table 1.
2. After adding the first dose recommended in the scheme below, fill each tank to 25% of the capacity with seawater and apply full heat. During this period, cleaning will be initiated due to wave motion.
3. Maintain this condition for one (1) day. Then raise the level in the tanks to 95% of capacity by further addition of seawater. If the sea is calm, be sure tanks are full enough so that the overheads will be in contact with the cleaning solution.
4. After the second day, strip the contents of the tanks. Add the second dose of TANK SUPER CLEANER using the scheme as before. Fill the tanks to 95% capacity with seawater and apply full heat. Maintain this condition for a minimum of one-two days if time permits.
5. After one or more days, strip the contents of the tanks. Refill the 90-95% capacity with seawater maintaining full heat. Strip the contents of the tanks with full heat on and flush with seawater.
