Safety-zone layout design for a floating LNG-Fueled power plant in bunkering process

Abstract

The use of natural gas (NG) as an energy source is increasing. This paper studies the safety-zone layout design of a floating power plant fueled by NG. Hazards from the unwanted release of liquefied NG (LNG) in bunkering or NG in operation always exist, and it is thus important to reduce the associated risk to an acceptable level. One engineering technique used to reduce this risk involves the design of a safety zone to prevent and minimize exposures that may occur during unwanted release of LNG or NG. Industry practices are available for the design of the layout of such safety-zones, but their applicability to floating power plants is uncertain, and a more intuitive approach is required. The objective of this study is to discuss the challenges of establishing safety zones on floating power plants by reviewing and comparing existing industrial practices and to propose a hybrid approach for the design of a safety-zone layout. The applicability of the proposed hybrid approach is discussed with an applied example.

Improving Liquefied Natural Gas Bunkering in Korea through the Chinese and Japanese Experiences

“…Lee et al [32] analyzed willingness to pay for replacing common fuels with LNG in the case of flour imports and found that consumers accept prices up to 36% higher than the average price. Park et al [33] studied the safety zone layout design of a floating power plant fueled by natural gas. They provided an example of a hybrid approach for LNG.…”

Human Error Probability Assessment for LNG Bunkering Based on Fuzzy Bayesian Network-CREAM Model

“…Some research studies have been conducted regarding the risks of LNG bunkering. These have mainly focused on the following three aspects: (1) safety zone evaluation [10][11][12][13][14][15][16][17][18][19][20][21][22], (2) risk assessment methodology and practice [23][24][25][26][27], and (3) emergency evacuation assessment [27,28]. Even though these studies have improved our understanding of LNG bunkering safety, none has quantified human errors in LNG bunkering.…”

Thermal analysis of marine structural steel EH36 subject to non-spreading cryogenic spills. Part I: experimental study

“…These liquified gases are cryogenic liquids meaning that they are cooled down below about −150°C. Liquefied gas leakage from cargo containments or fuel tanks of ships, as well as during bunkering of liquefied gases to vessels or offshore power plants, is a potential risk (Paik et al 2020;Park et al 2020). Such leaks can adversely affect the structural integrity of stiffened steel plates used in ship hulls and offshore structures by embrittling them at cryogenic temperatures (Paik et al 2020).…”
