The MARPOL Convention is the leading 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 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.

Mavi Deniz design a unique MARPOL CAT waste collection vessel 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.


  • Marpol Waste Collection Vessel bases on a robust steel hull.
  • Marpol Waste Collection Vessel has Twin Engines.
  • Hydraulic knuckle crane to for equipment handling operations.
  • Debris / Garbage reception & storage
  • Oily water reception. ( sludge, slop, bilge, sewage, dirty ballast water & oily waste liquids )
  • Sewage Treatment Systems & Oily Water Separator Systems
  • Fire Fighting
  • Accommodation with a cabin for the crew, WC & Bathroom, or a workshop can provide.


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 the washing of the cargo tanks of vessels, oily water wastes accumulated in slop tanks.
  • Dirty Ballast: ballast water that causes 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 sea.
  • Waste oil: dirty oils that lost its nature after being used by primary machines and auxiliary machines in the vessel. Solid sludge: oil sludge solidified at the bottom of the 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 live animals or other wastewaters are mixing with these.

3  ) Garbage/trash wastes under the scope of Marpol 73/78 Annex-V: trash: municipal and operational solid wastewaters formed due to the usual operation of the vessel and under the range 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 collection vessels in the world. Despite this, we go on to develop and improve MARPOL CAT floating slops reception and treatment vessels.
