Cleaning : Oily waste tank


The oily waste tanks, dirty oil tanks, bilge water, hydrocarbon sludge are subject to an accumulation of deposits at the bottom. (sludge, sediment, concretions, etc.)

These deposits can prevent the use of the tank (obstruction of the stainers / pumps during pump-outs).
A regular cleaning can therefore avoid these problems and to check the condition of the tank’s structure (corrosion).

The cleaning of ship tanks requires a high level of training and skills.
To do so, our technicians our properly trained and apply strict cleaning procedure and safety protocols.

Our procedure is based on high-pressure cleaning by using industrial degreaser.
We use high-tech equipment, in compliance with the regulation, gas detector (gas free test), ATEX gear (explosive environment), breathing devices, dry suits, 24V lamps, etc.

The waste from cleaning is taken away and transported to an authorised treatment centre. A waste tracking slip (BSD / WTS) is issued so as to ensure its traceability.
