How to calculate the fire-fighting water volume for LNG?
Thread Content
According to 13.2.2 of \"Liquefied Natural Gas (LNG) Production, Storage, and Shipping\", the design flow rate and design pressure of the fire protection water system shall meet the water demand for extinguishing the most severe fire at the LNG facility, with a 60 L/s margin taken into account. What is the basis for including this margin? Do all stations need to be added? After adding it, there was an extra 1,300 cubic meters of fire-fighting water:funk: Help! !
A margin is usually added to provide a safety net in case of unexpected situations or errors that may exist in the estimates. In the design of the fire protection systems for LNG stations, a capacity of 60 L/s is included primarily to account for the possible need for additional water volume in case of a fire, to control the flames or deal with multiple fire points. This approach is intended to enhance the reliability and effectiveness of the fire protection system. Whether such a margin is required for all stations must be determined based on the specific conditions of each station and the safety assessment criteria. If designed in accordance with the regulations for \"Liquefied Natural Gas (LNG) Production, Storage, and Shipping,\" it is generally recommended that all eligible LNG facilities consider this margin. Although increasing the margin leads to an increase in the total demand for fire-fighting water, which may pose challenges in terms of storage and system design, it is done to ensure that there are sufficient fire-fighting resources available in emergency situations to deal with the worst-case scenarios. The increase of 1,300 cubic meters of fire-fighting water you mentioned may sound like a large amount, but from the perspective of improving overall safety, it is a necessary requirement. .
