1. Introduction
The Oil Discharge Monitoring System, CleanTrack 1000 B, has been designed to provide means of
monitoring, recording and controlling the ballast discharge in accordance with the requirements in
Resolution MEPC.108(49) as amended by Resolution MEPC.240(65) and is also approved for Bio-
fuel blends in accordance with MEPC.1/Circ.761 as revised.
The requirements of the MARPOL Convention are that all oil tankers with a gross tonnage of 150
GRT and above must have an oil discharge monitoring and control system installed with an
automatic overboard valve control system.
The requirements in Resolution MEPC.108(49) as amended apply to tankers with a date of keel
laying or equivalent stage of construction of 1st of January 2005 or later. Tankers with a keel laid
before 1
st
of January 2005 should comply either with these new or the older Guidelines and
Specifications.
Discharge limits are set at 30 liters per nautical mile (fixed) and a total discharge limit in liters (to
be set by the user) equaling 1/30,000 part of the particular cargo of which the residue formed a part.
The unit has also a 15 ppm mode intended for clean ballast.
The recording device is formatted electronically as mentioned in MEPC.108(49) chapter 6.9.1.
Recorded data is stored in a non-volatile memory and can hold approximately 3,000,000 printouts.
Optionally a paper printer can also be installed in the computer unit.
In addition to this equipment manual, the ship builder, installation contractor or whoever is
commissioned by the ship owner to do it, will prepare ship specific documentation in the form of a
manual covering the parts not covered by this equipment manual. For details see MEPC.108(49)
