The MARPOL Convention is the main international convention that covers the prevention of pollution of the marine environment by ships due to operational or accidental causes. It is a combination of two treaties adopted in 1973 and 1978 respectively

and updated by amendments over the years.
The Convention includes regulations aimed at preventing and minimizing pollution caused by 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 hydrocarbons and oil-derived waste (bilges, mud, slop, used oils, contaminated ballast, etc.) MARPOL 73/78 Annex IV Regulations for the prevention of pollution by sewage and sewage.

MARPOL 73/78 Annex V

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


It has unique waste collection barges for MARPOL 73/78, which meets the requirements to collect waste from other ships; including passenger, cruise ships, cargo ships and oil tankers or tankers, at all times, in anchorage areas and ports.


1. The hydrocarbons delivered under Annex-I Marpol 73/78, which arise due to the normal activities of the vessels; Bilge: oily wastewater formed in the machine and sub tanks of auxiliary ships of ships, coffer-dams, warehouses or similar deposits of the ship.
Sludge: Sludge composed of residues and oily sediments formed in the engine rooms, fuel tanks of ships or cargo tanks of oil tankers.
Slop: Including tank wash water formed due to washing of cargo tanks of ships, oily waste water accumulated in slop tanks.
Dirty Ballast: Ballast water that causes oil, oil slicks or water to appear on shoreline or creates color changes above or below water or causes the accumulation of suspended emulsion/solid materials when released from the vessel to the water.
Residual oil: Dirty oils that have lost their nature after being used by primary machines and auxiliary machines in the container.
Solid sludge: Solidified petroleum sludge at the bottom of the vessel oil tank.

2. Sewage / sewage under the scope of Marpol 73/78 Annex IV: Sewage: waste from toilets, urinals and toilets, liquid waste from sinks, showers and discharges from areas where there are live animals or other waste water that is mixed with these.

3. Garbage / garbage residues under the scope of Marpol 73/78 Annex-V:
Garbage: garbage waste generated due to the normal operation of the ship and under the scope of marpol 73/78 annex-V.
Category-1: plastic.
Category-2: floating; stacking tools, lining or packaging materials.
Category-3: terrain; paper products, waste, glass, metal, bottles.
Category 4: paper products, waste, glass, metal, bottles, ceramics.
Category 5: food waste.
Category-6: furnace ash, excluding those composed of heavy metal waste or toxic plastic products.
We design the most modern waste collection barges in the world. Despite this, we continue to develop and improve MARPOL floating waste reception and treatment vessels.
