Zero hassle cleaning

We all know that cleaning Annex II cargoes can often be difficult, as the subsequent cargoes usually have different chemical properties than the cargo to be cleaned.

To make matters worse, the cargo to be loaded often has exceptionally high purity requirements (ultra-high purity cargoes).

Although cleaning clean and dirty petroleum products (CPP and DPP) is usually more straightforward due to the often very similar chemical properties, many exceptions can make cleaning quite complicated in individual cases.

Examples include aviation fuel or fuels with very low sulfur content. A particular difficulty arises when it is necessary to switch from black loads to clean loads (DPP to CPP).

Our experts have taken all of these cases into account when creating the cleaning procedures.

So you don’t have to worry if cleaning is required for any of the more than 180,000 load combinations covered in the book.
