Mechanical Cleaning of Tanks and Oil Reservoirs
It makes no sense to invest a lot of effort and money in successfully cleaning components and piping if the internal reservoir/tank is left in an unclean condition.
The reservoir/tank should be cleaned as well, and Ocean Team can provide such services. Depending on contamination type, tank conditions and customer requirements, our tank cleaning services include grinding with a mechanical grinding machine, wire brush or other suitable cleaning device in order to remove rust, iron scale, weld splatter, grease, dirt or other foreign matter, e.g. packing material.
If appropriate safety precautions are taken, kerosene solutions can be used to clean and degrease the inner surface of the tank. The surface should be dried with a clean, non-fluffy cloth (not waste). A strong magnet, putty or other suitable materials can be used to collect all loose dirt and metal particles from corners and from the bottom of the tank/reservoir. After thorough inspection of all parts of the tank, and repeated cleaning if necessary, all openings are sealed.
If required, the tank/reservoir is now ready for surface treatment with oil-resistant varnish or paint. If the inner surfaces are to remain untreated, the tank should be coated once with anti-rust oil, which is easily dissolved in the system oil, and afterwards closed and sealed. In systems where the tank is an integrated part of the machine, it should be cleaned and protected as described above before mounting.
Over many years, Ocean Team has gained vast experience in safety risk assessment when entering reservoirs/tanks and can therefore provide safety procedures and Confined Space Entry Authorisation together with our services.
