Rule 10 TSS: Traffic Separation Schemes

(Excludes any applicable taxes)

A definitive guide to navigating and collision avoidance when sailing through a TSS, this

book is a must for all deck officers when learning the application of Rule 10 of the COLREGS.

Kevin Vallance began his seagoing career at the age of 16 years with Shaw Savill and Albion Company Limited. After completion of his deck officer cadetship at Warsash School of Navigation he was employed as second mate with South Coast Shipping Company,working on marine aggregate suction dredgers in the limited European trading area.


In 1986 aged 28 years after obtaining a Limited European Trade command endorsement he was promoted to Master with that company, a role which he held for 19 years. At the age of 45 Kevin returned to South Tyneside College to complete his Masters foreign going unlimited certificate of competency. It was during the periods of shore study that he started to be concerned about standards of sea going watch keeping, in particular COLREG’s understanding and application.


In 2006 he became a Trinity House Licensed deep sea pilot, working with George Hammond Shipping. As a deep sea pilot Kevin has worked onboard a variety of vessel types including ultra-large container vessels, tankers, bulk carriers, cruise ships, car carriers and visiting war ships. His specialised local knowledge has also been utilised to assist with VTS services for cable and pipe laying operations and salvage works. This varied work has been with many different and often multi-national crews.


With a passion for safety at sea and in particular with navigation safety, Kevin is currently vice-chairman of the United Kingdom Maritime Pilots Association Technical and Training Committee whom he regularly represents at the United Kingdom Safety of Navigation committee meetings which are held by the Maritime and Coastguard Agency.

It was after attending an Anglo-French navigation meeting to discuss the possibility of introduction of a speed limit for all vessels in the Dover Strait in 2010 that the idea of this book was first discussed with other concerned people.Initial work with Witherby revolved around revision of the English Channel Passage Planning Guide, to which this book should be considered complementary.

Customer Reviews

Good Value, highly readable textbook leaves no excuses for TSS ignorance Review by Nautilus - September 2014
This new textbook on traffic separation schemes is intended to fill a gap in the available study materials – as explained by author Kevin Vallance in our profile on page 29. Written by an experienced deepsea pilot, the guide helps readers to understand a vital aspect of the international collision regulations and put the rules into practice.

Clearly and attractively laid out, Rule 10 TSS uses illustrations and contrasting colours to make the subject matter easily digestible. Captain Vallance told the Telegraph that readability was at the forefront of his mind when writing the book, and he particularly wanted to make it accessible to mariners whose first language is not English.

Efforts have been made to choose recent and highly relevant case studies, in order to bring home the importance of the Colregs and help students to realise that this is not an academic exercise. In addition, the price has been kept at a reasonable level and the paperback format isn’t too weighty, so there’s no excuse not to have a look at the book. Let’s hope everyone who needs this gets a copy and that safety at sea improves accordingly.
