This chapter presents a number of examples of accidents in high-risk industries taken from official accident report extracts and the safety literature and is intended to highlight a common and recurring thread in contributory factors to accident causation. It also presents a brief outline of the shipping industry. The Bow Mariner accident is perhaps the one accident that most clearly shows the potential effects of failure in organizational learning in the maritime industry as well as the attenuation of risk signals/perceptions in the risk cognition process. On the 26 August 2002 the fishing vessel Cistude collided with the Norwegian-registered chemical tanker Bow Eagle. The collision resulted in the loss of four lives and the spilling of 200 tonnes of ethyl acetate. On 25 May 2003, the S/S Norway had an accident involving the rupture of a boiler while berthed in Miami, Florida. The chapter also presents an overview of the key concepts discussed in this book.
