Captain Henk Hensen is a Master Mariner FG. After his career at sea he became a Port of Rotterdam pilot for 23 years, during which time he started the first combined simulator training courses for harbour pilots and tug captains, and participated in many port studies, including simulator research. Following his piloting career he continued to work as a marine consultant on the nautical aspects of port studies, harbour tug advice and simulator training and research, and as an expert witness. As an author, his publications include Ship Bridge Simulators (1999), Tug Use in Port (2003), Tug Stability (2016), co-authored with Dr Markus van der Laan, and numerous articles in nautical magazines. Captain Hensen is a Fellow of The Nautical Institute and of the International Tugmasters Association, and a member of the International Federation of Shipmasters. He was elected Tug Personality of the Year 2010 by the British Tugowners Association.
Tug Use in Ports
First published in 1997 ‘Tug Use in Port’ has been known for over two decades as the ‘tug bible’ – the essential practical guide to port towage and escort operations. Since the publication of the last edition – which was recommended as a standard text by the IMO – developments in tug design and operation have continued to improve tug capabilities, as well as effective and safe tug use.
Significant developments in port towage have taken place since then – new tug types have come on to the market with new and specific manoeuvring capabilities and an increasing number of environmentally friendly tugs can be found, with traditional fuels being replaced by LNG, CNG and batteries. Escorting and escort tugs have been developed further also with regard to the conditions that these tugs have to cope with. An increasing number of LNG carriers and bulk carriers are being escorted, in addition to tankers; remote controlled and autonomous ships are no longer simply the stuff of science fiction, and will have an effect on tug operations.
Sadly, there have also been several accidents, often with dramatic consequences. But on the positive side, training possibilities have further developed, with improved training tools and ever more realistic and sophisticated simulators.
At the centre of all these developments and changes are the people – tug masters and crews, pilots and ships’ captains – who need to be able to handle the newly designed tugs and their equipment in a safe and efficient way. This book is designed to help them achieve that.
