Tug Stability A Practical Guide to Safe Operations

Captain Henk Hensen and Dr Markus van der Laan

Price: £25.00 Hardback ITS Club Discount Available of 10%

Numerous harbour tugs have capsized, often with tragic consequences: during the five-year period 2010-2015, more than 45 people are known to have drowned in capsizing incidents.
Stability is a complex subject and mainly a specialism of naval architects. Tug masters seldom have this detailed knowledge - yet they experience the effects of a tug's stability every day when manoeuvring their tug, either free sailing or when assisting ships.

Tugs will often be working with towline forces, hydrodynamic forces, steering and propulsion forces at or near their maximum with respect to the vessel's stability. It is, therefore, not just desirable but necessary for tug masters to have at least a basic idea of the elements of stability. They need to know where the limits are, and what the consequences could be, if tug handling practices don't conform to the rules of stability in normal circumstances and also when extreme conditions such as dense fog and storms occur.

Furthermore, a tug's stability is not a static condition but can change with every moment. Alterations in the amount of bunkers or stores, water on deck, slack tanks and ice accretion, all complicate the stability situation. These various factors could combine to affect stability in a negative way and may even culminate in a very dangerous situation for the tug.

In writing this handbook, master mariner and pilot Captain Henk Hensen and naval architect Dr Markus van der Laan have focussed on the practical aspects of stability, tug design and equipment and also on the consequences of unsafe procedures. Their emphasis is on harbour tugs, although several of the topics covered apply equally to seagoing tugs.

REVIEWS

A practical, readable, expert handbook, Tug Stability - a Practical Guide to safe Operations is essential reading for all tug masters, who experience the effects of their vessel's stability every day, whether free sailing or assisting ships.
MarEx Review - 17 June 2016

"This tug stability book will greatly contribute towards safer towage operations by enhancing the working knowledge of tug masters. It is an important publication for all tug masters and towage managers, no matter what facet of the towage industry they are engaged in."
Arie Nygh, ITA Patron; Managing Director, SeaWays Consultants

".....it appears that you have once again done the industry a great service by compiling such a useful document for vessel operators. We have multiple copies in our office and will ensure that our designers also read it and understand thoroughly so that we can do our best as designers to achieve our mutual long term goal of much safer tugs!"
