At the request of the publishers, I have now refreshed, updated, and hopefully improved on this 2006 edition. In 2006, I updated the 1999 edition of Ship Stability for Masters and Mates.
Therefore, there will be no suffix ‘T’ for transverse stability calculations but there will be a suffix ‘L’ for the longitudinal stability text and diagrams. longitudinal stability, then BML, GML, and KML will be used to denote the longitudinal considerations. Throughout this book, when dealing with transverse stability, BM, GM, and KM will be mentioned and used in calculations. The book will also prove to be extremely useful to other maritime personnel shown listed in the Introduction. It is primarily for Chief Mates and Officers on Watch (Officers in Charge) on board merchant ships. This book is written specifically to meet the needs of students studying for their Transport Certificates of Competency for Deck Officers and Engineering Officers and STCW equivalent International qualifications. He has lectured at a great number of UK Universities and has advised many Ship-owners on the above listed Specialist topics. They include the PLA, Milford Haven PA, Liverpool PA, Humberside PA, Tyne PA, Truro PA, Newhaven PA, Bordeaux PA, Klaipeda PA, Nantes PA and Hamburg PA.ĭr Barrass has supplied Ship Squat and Interaction information to 22 countries worldwide. He has worked with many national & international Port Authorities. His interest in Ship Squat began in April 1972, starting on research for his Ph.D. He became a visiting Lecturer and has written seven books involving Ship Stability, Ship Design & Ship Performance and Ship Squat & Interaction. From 1967 to 1993, he worked at Liverpool John Moores University, lecturing to Maritime Degree students, Masters, Mates, and Marine Engineers. In 1963, he then became a Lecturer in Naval Architecture in Sunderland. Concepts are supported with numerous worked examples, clear diagrams, graphs and equations to assist with understanding and application of this critical subjectĭr Bryan Barrass worked as a Ship Draughtsman for 11 years at Swan Hunters Shipyard in Wallsend.Provides a comprehensive introduction to all aspects of ship stability and ship strength, squat, interaction and trim, materials stresses and forces.
Updated throughout to include new shipping industry developments and regulations, with 9 new chapters, the latest ship stability datasheets, and sample exam questions.This book is intended for students seeking to obtain Transport Certificates of Competency for Deck Officers and Engineering Officers and STCW equivalent International qualifications, as well as Chief Mates and Officers on Watch (Officers in Charge) on board merchant ships and other maritime personnel, port authorities, marine consultants, nautical study lecturers, and marine superintendents. The book also includes extracts from the 1998 Merchant Shipping (Load Line) Regulations Number MSN 1752(M). Other chapters focus on timber ship freeboard marks, procedures and calculations for drydocking and stability, and ship squat in open water and in confined channels. The reader is also introduced to free-surface effects of slack tanks with divisional bulkheads, how side winds affect ship stability, and the correlation between freeboard and stability curves. It considers large-angle stability, the effect of beam and freeboard on stability, and hydrostatic curves and values for vessels that are initially on even keel.
The book explains how to perform KB, BM, and KM calculations and make graphics on metacentric diagrams. It also explains how TPCs are calculated for a range of drafts extending beyond the light and loaded drafts, along with form coefficients, including the coefficient of fineness of the waterplane area. Organized into 56 chapters, the book looks at the relationship between ship stability and ship motion, with emphasis on group weights in a ship. Ship Stability for Masters and Mates explores all aspects of ship stability and ship strength, squat, and interaction and trim, as well as materials stresses and forces.
