The MARPOL Convention is the main international convention covering prevention of pollution of the marine environment by ships from operational or accidental causes. It is a combination of two treaties adopted in 1973 and 1978 respectively and updated by amendments through the years.

The Convention includes regulations aimed at preventing and minimizing pollution from ships – both accidental pollution and that from routine operations – and currently, contains six technical Annexes.

MARPOL 73/78 Annex I Regulations for the prevention of pollution by Oil and petroleum-driven wastes (Bilge, Sludge, Slop, Waste oil, Polluted ballast, etc.)

MARPOL 73/78 Annex IV Regulations for the prevention of pollution by sewage and wastewater.

MARPOL 73/78 Annex V Regulations for the prevention of pollution by garbage and trash. Governments are required to ensure the provision of adequate reception facilities at ports and terminals for the reception of MARPOL 73/78 Annex IV, V.

Presermar design unique barge for MARPOL 73/78 requirements to collect wastes from (other ships includes Passenger, Cruiser Ships, Cargo Vessels and Oil/Chemical Tankers) round the clock and time saving while waiting at anchorage, during bunkering or just for disposing of waste


1. Oil and oil delivered wastes under the scope of Marpol 73/78 Annex-I which arise due to normal activities of vessels;

Bilge: percolating water and oily wastewater formed in the machine and auxiliary machine sub-tanks of vessels, coffer-dams, warehouses or similar sections of the vessel.

Sludge: Sludge composed of residue and oily sediments formed in engine rooms, fuel tanks of vessels or cargo tanks of oil tankers.

Slop: Including tank washing water formed due to washing of the cargo tanks of vessels, oily water wastes accumulated in slop tanks.

Dirty Ballast: Ballast water that cases the appearance of oil, oil derived stains or oil stains above water or at the coastline or that creates color changes above or underwater or causes accumulation of solid materials/emulsion in suspension when released from the vessel to water.

Waste oil: Dirty oils that lost its nature after used by primary machine and auxiliary machines in the vessel.Solid sludge: Oil sludge solidified at the bottom of oil tank of the vessel.

2. Wastewater/sewage under the scope of Marpol 73/78 Annex-IV: Sewage: wastes from toilets, urinals and toilet scuppers, liquid wastes from lavabo, scuppers, and basins in infirmary, dispensary and hospitals, discharge from areas where there are live animals or other wastewaters mixing with these.

3. Garbage/trash wastes under the scope of Marpol 73/78 Annex-V: Trash: Garbage disposal formed due to the usual operation of the vessel and under the scope of marpol 73/78 annex-V.

Category-1: plastic

Category-2: floating; piling tools, coating or packaging materials

Category-3: ground; paper products, scraps, glass, metal, bottles

Category-4: paper products, scraps, glass, metal, bottles, pottery

Category-5: food wastes

Category-6: kiln ashes excluding the ones composed of heavy metal wastes or toxic plastic products.

We design one of the most modern waste collecting barge in the world. Despite this, we continue to develop and improve MARPOL floating slops reception and treatment vessels.
