Abstract

This paper suggests an example guideline of a safety zone layout for the domestic LNG Truck-To-Ship (TTS) bunkering. The safety zone is one of the controlled area in LNG bunkering and its layout is required as a fundamental safety barrier. While the international standard provides a layout methodology of the safety zone, its detail application is not user-friendly and only possible with a level of the process engineering. In the domestic case, the enforcement regulations are applied for LNG bunkering but the safety zone is not properly defined for TTS operation. Considerations are made for the intuitive approach of the safety zone layout and an example guideline is suggested for application in the domestic TTS bunkering. A technical background of the guideline is described and its applicability is demonstrated with regard to the characteristics of TTS bunkering. The findings of the study are summarized in association with a practical layout of the safety zone, contributing to the safety culture in the domestic LNG bunkering.
