Dr. Verweys Tank cleaning guide contains cleaning proposals for frequently shipped bulk liquid cargoes. This comprises Noxious cargoes regulated by Annex II as well as oil cargoes regulated by Annex I of the MARPOL convention. The cleaning of Annex II cargoes is often very 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 extremely high purity requirements (Ultra High Purity Cargoes).
In shipping of Clean and Dirty Petroleum Products (CPP and DPP), the cargoes differ little in terms of their chemical properties and thus complicated cleaning is less common than in chemical shipping. But there are many exceptions to this rule because some cargoes in this trade have also high purity requirements. Examples include aircraft fuel or fuels with very low sulphur content. A particular difficulty arises when it is necessary to switch from Black cargoes to clean cargoes (DPP to CPP).
All of these special features are taken into account in the database. The Verwey app can thus provide reliable recommendations for all cleaning tasks.

The new IBC code, which has been in force since January 1st of this year, has brought a lot of significant changes with it.
Many cargoes have been classified as toxic. A very important change is the introduction of so-called persistent floaters, which always require a prewash in European coastal waters.
