Abstract

The energy transition issue is being pursued following the outcomes of the 22nd Summit by the G-20 group. The use of Liquified Natural Gas (LNG) fuel has emerged as one of the solutions in addressing the energy transition challenge. In line with the issuance of the Ministry of Energy and Mineral Resources Decision in January 2022, the Indonesian Government will increase the utilization of natural gas in the form of LNG for the electricity generation sector. LNG fuel is considered to possess numerous advantages and is more environmentally friendly. The distribution of LNG fuel is often carried out by tanker ships equipped with cryogenic tanks called LNG carrier. However, challenges arise when ships operate in waters which has high sea state condition, where the vessel faces the risk of accidents such as sloshing, increased motion response, stability disruptions, and other. Therefore, this paper provide a comprehensive risk analysis to minimize the existing accident risks caused by varied sea state condition using Risk-Based Design (RBD). RBD is a structured and systematic method to ensure safety levels and cost-effectiveness and utilizing risk analysis.
