LNG Bunkering QRA: A Case Study on the Port of Piraeus

Abstract

Abstract: The use of LNG as maritime fuel is a viable option when it comes to reducing the harmful emissions produced by vessels throughout the world, to comply with IMO's Annex VI requirements. However, since the concept is gaining constant focus, special attention must be paid, so that stakeholders fully comprehend LNG's unique properties and hazards, as well as be aware of the standard procedures and best practices that must be followed when handling and storing LNG. In this paper, a Quantitative Risk Assessment (QRA) methodology is presented along with its application on an LNG bunkering case study at the Port of Piraeus. As a result, LNG's properties are considered, potential hazards are identified, failure frequencies are determined, and accidental consequences are modelled. Having evaluated these parameters, Individual Risk (IR) is assessed, safety distances are outlined, risk drivers are identified.
