Sludge builds up in tanks and vessels over time. The sludge needs to be removed at regular intervals in order to maintain a smooth running operation. Sludge removal can be a hazardous task if performed manually. For this reason tank and vessel sludge removal is carried out remotely wherever possible, or with minimum man-entry in confined spaces. A range of technologies have been developed for the oil and gas industry, as well as the chemical industry and others for sludge removal. Vacuum transfer systems can pump sludge safely from its source to a transport or storage source.

Apart from someone controlling the system remotely, no one needs to be near or even very close to the tank or vessel having its sludge removed. Of course, often it isn’t possible to remove sludge, mud or scale from a tank or vessel by a remotely controlled system and no man-entry requirement. Often man-entry becomes essential, and often too it is in a confined and awkward space, which makes the operation potentially hazardous.

Tank and vessel sludge removal is not usually an easy job. It requires a high emphasis on safety for those involved. For this reason remote sludge removal systems are preferred, but unfortunately are not always practical or possible to use.

Our technical team/experts can check the organic lead pollution status in the areas. Prior to commencing the activities the team leader debriefs the manager of the facility on the hazards and specific requirements, and safety meetings are regularly held during the works. The plant decommissioning starts: plant piping and tanks are opened with cold cutting techniques, any liquid or residual sludge it is possible to pump out is removed using pneumatic pumps and collected in storage drums.

Revised MARPOL Annex V sets new regulatory requirements regarding the disposal of garbage from ships and it came into force at the beginning of this year. The new amendments prohibit the disposal of almost all kinds of garbage at sea with the exemption under specific requirements of food waste, cargo residues contained in wash water and environmental friendly cleaning agents. As a result of these regulations more and more ships are disposing their ship-generated waste to reception facilities ashore.
