UIP Guidelines on tank cleaning levels and cleaning key

Guidelines developed by UIP Superstructure Committee

With the present guideline, the UIP working group “Cleaning levels” intends to give users assistance with the aim of progressing towards a standardisation of appraisals.

The present issue of this guideline focuses initially on particularly controversial assessments. The UIP invites users to discuss any points and will gladly consider suggestions. The guideline can be expanded by the UIP if necessary.

This manual was developed by a working group of the UIP after their best knowledge. The UIP cleaning key supports a standard assessment of tank interiors and all items of equipment coming into contact with the product carried. It provides a basis for describing a cleaning condition of a tank. Detailed information on e.g. pores, adhesions or minor shading effects is to be agreed on additionally.
