Abstract

Sunda Strait has played an essential role to the Indonesian marine transportation. Safety of navigation is one issue that often leads to an accident, especially ship collision. A collision risk assessment in a waterway is critical not only to predict the probability of collision accident but also to understand its consequences to human life, shipping company, as well as to the environment. However, it could be hard to evaluate the accident due to the scarcity of real accident data. Thus, a near miss analysis can be considered as an equivalent substitute. A one-week of Automatic Identification System (AIS) data is taken as the sample to test the methodology proposed in this paper. The target area of the near miss analysis discussed in this paper is TSS area in Sunda Strait. To categorise the encounter as a safe or unsafe encounter, this paper utilises the closest point of approach (CPA) as the indicator and it contains two parameters, the distance to CPA (DCPA) and the time to CPA (TCPA). Four values of DCPA and TCPA are used as the threshold, those are introduced by Park, Fukuto and Imazu, Goodwin, and Limbach. In this time range, 135929 sample data are collected, but only 92,379 points from 276 ships are found inside the target area. The number of situations that are categorized as near miss encounters (NNM) for each threshold are 1668, 5870, 9370, and 13549, respectively. The combined threshold is proposed to adjust with the condition of Sunda Strait and produce a result with 9,946 points detected as near miss encounter.
