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.

Before starting the activities, our decontamination specialists and all the project team members undergo bio-medical checks to ensure that they are fit for work in harsh conditions and to test the lead levels in their blood. Field TEL Analyzers are tested, calibrated and shipped together with chemical engineers, experts in handling the instrumentation and authorized to issue Lead Free/Gas Free certification. Appropriate environmental control systems are set up in the work areas and in areas that might be affected by the activities.

Our chemical engineers and/or environmental experts can check the organic lead pollution status or the status of other volatile compounds in other areas of the premises if deemed to be required by the client. 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 UN and ADR storage drums. Tanks are ventilated to remove any organic lead in the air, and explosive potential levels are checked. When acceptable levels have been reached operators enter the tanks and clean the surfaces to attain a gas-free status. After this, hot cutting is carried out and the tanks and rest of the plant are sectioned, pickled and flamed out until no organic lead is present.

Once the decommissioning has been completed we issue TEL-Free Certification.
