Based in Marseilles-Fos, SERMAP specialises in the collection, transport, recycling and treatment of industrial waste products and liquid residues from cargo and shipping vessels. With their own vacuum trucks, tank trucks and a barge, they have been responding to the needs of calling ships and shipping agents for more than fifteen years.

Reliable services

SERMAP provides full site supervision. They always sample and analyse waste materials. This makes it possible for them to use appropriate pumping and skimming procedures based on the type of waste they are handling. SERMAP is qualified to produce and deliver Marpol certification. This demonstrates that waste materials have been correctly recycled based on the different classifications for waste.

Equipment and resources

The handling and transport of sludge, slop and bilge water is carried out by barge, vacuum trucks or tank trucks based on accessibility and the amount and type of waste being collected.

The SERMAP fleet includes:

  • 2 vacuums trucks (10 to 20 m³)
  • 6 tank trucks (9 to 28 m³)
  • 1 barge (up to 300 m³)

SERMAP intermediate storage containers:

  • Tank containers (6, 10 and 20 m³)
  • Easy-to-transport tritox systems (1 m³)


When a tank is drained, liquid hydrocarbons and oils are often left behind. This residue is known as ‘sludge’. While it usually contains liquid in very low levels, it is possible for it to completely dry out and solidify. This means specialised pallet pumps need to be used to remove sludge. It is also (temporarily) stored in dedicated sludge tanks. SERMAP generally use trucks to perform sludge-removal services, but will use their barge if circumstances demand it.


Under normal circumstances, cargo tanks are drained of dirty water known as ‘slop’ after every commercial operation (loading/unloading). This process is known as de-ballasting. In commercial ports, there is generally a pipeline making it possible to pump slop directly to refining stations. But if this is not an option? SERMAP can rely on their fleet of trucks and storage tanks, as well as the 300 m3 storage capacity of their SERMAP barge to lighten your load in an environmentally-responsible manner.

Bilge water

On cargo ships, water recovered on lay days, as well as water used for washing, are stored in the bilge water tank. SERMAP drains these tanks and processes the oily water at excellent rates.

Used oil

SERMAP takes drums of used oil from vessel engines off your hands. Vans are used for transportation and all treatment processes meet the demands of the Marpol Convention.

Hazardous and special wastes

Other waste needs to be dealt with in environmentally-friendly manner. This includes oily rags, packaging, used paint cans and worn-out ropes, as well as potentially dangerous materials such as waste containing chemicals and out-of-date distress signals and medical devices. SERMAP uses environmentally-responsible processes to recycle or destroy these waste products.
