Man entry for tank cleaning – confined spaces.

Where required we have confined space qualified teams for man entry to the tank. They can ensure the tank is cleaned to the highest standards. As tanks begin to empty of their contents, that introduces air into the tank space. Some of the lighter chemicals in the oil or fuel begin to vaporize. This fuel-air mixture can be more volatile than the fuel itself due to the oxygen introduced into the gas. Best practice techniques
Our highly trained professionals have advanced cleaning systems that give them a couple of options. Inerting or purging the gas, pushing the fuel-air mixture out of the tank. That can either be replaced by an inert gas or assessed to check that the tank atmosphere is deemed safe.

These industrial tank cleaning techniques are most relevant to removing the tanks after removal of the fuel. It also applies to change of product within cargo tanks, chemical tankers and oil tankers where cargo vapour may contaminate the new product.
