Philippe Boisson, communications manager and legal advisor to Bureau Veritas' Marine Division, has recently authored a book, Safety at sea: policies, regulations and international law, focuses on preventing accidents and evaluating safety at sea. Boisson, who has been following safety system developments for more than twenty years, researched recent sea disasters, such as Braer in 1993; Estonia in 1994; and Sea Empress in 1996. The book is the result of five years research that set out to answer a myriad of questions that, according to Boisson, "always arise after the aftermath of an accident." Specifically: Could disasters at sea be prevented? Are safety levels adequate? Are protective measures appropriate?
