This article briefly introduces the objects and the achievements of the Maritime Safety Initiative. It was a two-years project completed in 2011. At the beginning of the project, we invited experts of maritime safety from the government and held a free discussion. As an introduction of the project, the contents of the discussion are summarized, risk factors of maritime accidents and their control options are explained and the recommended challenges for NMRI are presented. Based on the recommendations, we have developed two key technologies. One is maritime accidents database. Key information in the accident reports of Marine Accident Inquiry Agency are extracted by text processing technique and stored in the database. Using this database, we can distill stochastic facts from the vast amount of maritime accident reports. This database is also useful to extract individual process of failure navigation at the accident to study human factors. The other is marine traffic simulator. This simulator was originally developed by Prof. Hasegawa in Osaka University and has a capability to simulate legal collision escape process of two ships in various encounter conditions. Based on the simulator, we have expanded its functions to estimate the quantitative effectiveness of various counter measures to avoid collisions and groundings.
