Ebook Tug Use in Port

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.  Significant developments in port towage have taken place since then – new tug types have come on to the market 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.

The fourth edition of ‘Tug Use in Port’ has been fully revised and updated and now contains information on decision support systems on board tugs, full electric tugs, tug operations in swell, stopping a ship by tugs, new escort and carrousel tugs and assisting navy ships.

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.

Ebook Tug Stability

Tug masters experience the effects of a tug’s stability every day when manoeuvring their vessel, either free sailing or when assisting ships. During tug operations, a number of forces and combinations are working on a tug, often at or near their maximum with respect to the tug’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 the tug or tug handling practices don’t conform to the rules of stability – not only in normal circumstances and but also when extreme conditions, such as dense fog and storms, occur. The consequences can be very dramatic. Numerous harbour tugs have capsized, often with tragic consequences.

This educational guide to stability specifically for tugs aims to provide this important information to tug masters. It is written in a manner readily understood by all tug masters, regardless of their education, formal qualifications, nationality or operational backgrounds. The text is accompanied by numerous illustrations and photographs.

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.

The book is not just for tug masters but for all those in one way or another involved in tug operations.

Ebook Bow Tug Operations with Azimuth Stern Drive Tugs

The first edition of ‘Bow Tug Operations with Azimuth Stern Drive Tugs’ was published in response to a number of accidents involving bow-to-bow operations with ASD-tugs and discussions in some ports about how such tugs should be employed as bow tugs.Bow tug operations at a ship having headway are very risky, particularly in the case of ships with a very high speed on dead slow ahead – a situation increasingly seen with large container vessels.  The problem starts with the approach towards the bow and then with the procedure of passing the towline. Because of the risks involved, tug masters that have to carry out bow tug operations, and particularly tug masters of ASD-tugs that have to operate bow-to-bow, should be well trained and aware of all the possible risks. These issues are all dealt with in this book in an easy understandable way, resulting in a set of guidelines for safe operations at the bow. Furthermore, the book discusses several
crucial aspects that play an important role in bow-to-bow operations, such as skeg and stern design. As the skeg is such an important appendage for carrying out bow-to-bow operations at a ship having speed, more attention has been paid to skeg design and the effect of differences in skeg design on bow-to-bow operations. Suggestions for some test trials using your own tugs have been added in order to be able to learn about its specific suitability for bow-to-bow operations, with images explaining the trials discussed – all again focusing on the safety of tugs, tug crews and attended ships. Finally, since speed, which means speed through the water, is so critical for safe bow tug operations, renewed attention has been paid to this important aspect.

Tug Stability

Over the years numerous harbour tugs have capsized, often with tragic consequences. 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.

Bow Tug Operations

Bow tug operations at a ship having headway are very risky, particularly in the case of ships with a very high speed on dead slow ahead – a situation increasingly seen with large container vessels. The problem starts with the approach towards the bow and then with the procedure of passing the towline. Because of the risks involved, tug masters that have to carry out bow tug operations, and particularly tug masters of ASD-tugs that have to operate bow-to-bow, should be well trained and aware of all the possible risks.

These issues are all dealt with in this book in an easy understandable way, resulting in a set of guidelines for safe operations at the bow. This third edition has been updated for several crucial aspects that play an important role in bow-to-bow operations, such as skeg and stern design. As the skeg is such an important appendage for carrying out bow-to-bow operations at a ship having speed, more attention has been paid to skeg design and the effect of differences in skeg design on bow-to-bow operations.

A good stern design is also important for bow-to-bow operations, so stern design has been further dealt with here. Further subjects have been extended or renewed: proper radar use, bow approach manoeuvres, and new tug performance diagrams have been included. As bow-to-bow operations present high risks, additional attention has been paid to this particular issue.

Suggestions for some test trials using your own tugs have been added in order to be able to learn about its specific suitability for bow-to-bow operations, with images explaining the trials discussed – all again focusing on the safety of tugs, tug crews and attended ships.

Finally, since speed, which means speed through the water, is so critical for safe bow tug operations, renewed attention has been paid to this important aspect.
