DR. VERWEY'S TANK CLEANING GUIDE is the tank cleaning reference for chemical and product tankers. It answers one question for every cargo transition: how to clean the tank from the last cargo to the next.

The cross table covers 400+ bulk liquid cargoes and 180,000+ cargo transition combinations. Each cargo transition leads to a procedure code in the cross table and to one of 90+ step-by-step cleaning procedures in the Guide.

ChemServe GmbH maintains and publishes the Guide. The cross table and the cleaning procedures are generated from the MIRACLE cargo database. For decades the Guide has been the industry's reference for tank cleaning on chemical and product tankers. The 13th edition is published in November 2026.
