  • 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.

  • The number of ships using liquefied natural gas (LNG) as fuel is increasing to respond to the International Maritime Organization's (IMO) air pollutant emission regulations. At the same time, the need to expand LNG bunkering infrastructure for stable fuel supply and demand for ships is emerging. LNG bunkering is carried out in three ways: truck to ship (TTS), pipe to ship (PTS), and ship to ship (STS). In foreign countries, all three methods are being carried out, but in Korea, LNG bunkering is carried out only with the TTS method owing to the lack of infrastructure. LNG bunkering is a high-risk operation. For safe bunkering operations, the competence of the workers is extremely important, and a professional training course is required to strengthen the competence. This study was conducted to design training contents for LNG bunkering workers for fostering LNG bunkering experts and performing safe and systematic bunkering work. To this end, the current status of LNG-fueled ships and bunkering was identified, and related domestic and abroad educational contents were analyzed. In addition, opinions on the importance of educational contents were collected through expert questionnaires. Consequently, we designed training contents suitable for various training targets and divided them into basic and advanced training courses, with a duration of 4 days, and proposed. Based on the designed training contents, if additional research is conducted by sufficiently reflecting Korea's bunkering environment, it will be of great help to improve the competence of LNG bunkering workers and to foster human resources.
