Abstract

The designation of Karimunjawa as a National Park in 1999 does not prevent any shipping activities performed by barges, passenger ship, LCT, or even tanker from entering Karimunjawa waters. Such condition can cause damages to coral reefs if the ship run aground. In addition, the possibility of coral reefs contamination due to tourists activities such as diving that requires vessels to transport them. Based on the historical data from 2017 until 2023, fourteen cases of vessel grounding in Karimunjawa were recorded. This study comprises of hazard identiLication, frequency analysis, severity analysis, and risk representation. The simulation result of IWRAP Mk2 shows that the grounding incident in Karimunjawa is 3.736 incidents/year. Meanwhile the projected coral reefs area that affected by the grounding incident reached 0.55% from the total coverage. Based on Risk Management Australia AS/NZS 4360 (2004), the results showed that support vessels have high risk of grounding, followed by passenger ships with a moderate risk level. Tankers and other types of vessels were found to have a low risk of grounding.
