Dr Verwey’s 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 and the cargo to be loaded often has extremely high purity requirements (Ultra High Purity Cargoes).
In the shipping of Clean and Dirty Petroleum Products (CPP and DPP), the cargoes differ little in terms of their chemical properties and complicated cleaning is less common than in chemical shipping. However, there are many exceptions to this rule because some cargoes in this trade also have 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).
Verwey provides reliable recommendations for all cleaning tasks.
