Marine Bilge Water Treatment System

1. RESOLUTION MEPC.107(49) General INTRODUCTION:

1). The specifications in respect of 15 ppm Marine Bilge Water Treatment Systems are considered to be applicable for use in conjunction with oily bilge-water and ballast water from fuel oil tanks, as these are of a low or medium capacity, and are conditioned by the need to avoid discharging oil mixtures with an oil content more than 15 ppm of the mixture.

2). It is recognized that the development and testing of high capacity separating equipment designed for dealing with effluent from cargo tanks on tankers pose special problems and such equipment does not require to be tested under these specifications. Such development and tests should not be hindered and Administrations should be prepared to accept deviations from these specifications when they are considered necessary in this context.

3). It should be understood that a 15 ppm Marine Bilge Water Treatment System must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship, and deal satisfactorily with oil of very high relative density, or with a mixture presented to it as an emulsion. Cleansing agents, emulsifiers, solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify. Proper measures should be taken to minimize the presence of these substances in the bilges of a ship. With the possibility of emulsified bilge water always present the 15 ppm Bilge Water Treatment System must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15 ppm.

4). Where a range of 15 ppm Bilge Water Treatment Systems of the same design, but of different capacities, requires certification in accordance with these specifications, the Administration may accept tests in two capacities within the range, in lieu of tests on every size, providing that the two tests actually performed are from the lowest quarter and highest quarter of the range.

2. Summary of Marine Bilge Water Treatment System

The approval requirements for pollution prevention equipment specified in these Guidelines and Specifications are summarized below:

1). the 15 ppm Bilge Separator should be tested for type approval in accordance with the procedures described in part 1 of the annex, subject to environmental tests specified in part 3 of the annex; and
2). the oil content meter for the 15 ppm Bilge Separator effluent discharge, hereinafter referred to as the 15 ppm Bilge Alarm should be tested for type approval in accordance with MARPOL 73/78 relating.

3. Pollution prevention equipment

The marine bilge water treatment system should containing below device:

1). 15 ppm Bilge Separator;
2). 15 ppm Bilge Alarm; and
3). automatic stopping device
