NEW 2018: “Chemical Tanker Operations for the STCW Advanced Training Course”
The culmination of almost 3 years work; this publication is a very comprehensive guide to chemical tanker cargo operations. It is an essential reference point for serving officers, chemical tanker ship operators and managers, as well as those undertaking advanced training as required by the STCW Convention.

“With a wealth of knowledge in chemical handling and transport, CDI’s members felt it was essential to draw upon their collective expertise to produce a guide that would not only support the continuity of practical knowledge within the wider chemical tanker industry, but assist candidates studying for the Advanced Training for Chemical Tanker Cargo Operations (STCW) course”. said CDI’s General Manager Howard Snaith. He went on to say, “CDI has worked closely with all stakeholders in producing this book, including chemical manufacturers, charterers and parcel tanker operators”.

The book is written as a practical sequential prompt, an aide-mémoire for serving officers and managers, and as a consolidated study guide for those undertaking the advanced training for chemical tanker cargo operations as required by the STCW Convention.
