This paper, which was originally presented at the Fourth International Symposium on Vessel Traffic Services held in Bremen from 28 to 30 April 1981, here summarizes the results of an investigation into collisions world-wide, with particular emphasis on the circumstances of collisions associated with different types of encounter for conditions of both clear and restricted visibility.
Information relating to the circumstances of collisions is available from various sources but analysis of casualty information has usually been restricted to ships under one flag and been mainly applicable to accidents in restricted waters.
