3.1.1. Function and main parts
Purpose and function of the CleanTrack 1000B.
On an oil tanker the CleanTrack 1000B monitors and controls the discharge of oily water from a slop tank to the sea
according to MARPOL Annex I regulation 34, and it is specified in detail in IMO resolution MEPC.108(49).
When water is pumped from the slop tank into the discharge pipe, it can be diverted either back to the slop tank via a
slop tank valve, or over board to the sea via an overboard valve.
Normally the overboard valve is closed and the slop tank valve is open, diverting the water back to the slop tank. The
water can be diverted to the sea only when the CleanTrack 1000B enables opening of the overboard valve.
The CleanTrack 1000B samples water from the discharge pipe and measures the oil content of it. The CleanTrack
1000B also receives info about the ship’s speed (from the ship’s speed log or the GPS), the water flow rate from a flow
meter in the discharge pipe, and the ship’s position (from the GPS). Based on this info, the CleanTrack 1000B
calculates the instantaneous discharge rate of pure oil per nautical mile, and the total quantity of pure oil discharged.
The instantaneous rate of discharge of oil content must not exceed 30 liters per nautical mile, and the total quantity of
oil discharged into the sea must not exceed 1/30000 of the total quantity of the particular cargo of which the residue
formed a part.
When start pumping water from the slop tank, the water is diverted back to the slop tank. When the CleanTrack
1000B has determined that none of the above discharge limits are exceeded, it enables diverting the water into the
sea. When any of the discharge limits are reached, or there is a failure of the CleanTrack 1000B or any of the external
signals are missing, the overboard valve is automatically closed and the slop tank valve is opened. These events and
the corresponding ship’s position are recorded by the CleanTrack 1000B.
