BS EN ISO 20257-2:2021

What is ISO 20257-2- Design of floating LNG installations about? 

ISO 20257-2 provides specific requirements and guidance for the design and operation of floating LNG storage and regasification units (FSRU). 

ISO 20257-2 includes requirements to the jetty when an FSRU is moored to a jetty. 

Who is ISO 20257-2- Design of floating LNG installations for?  

ISO 20257-2 on the design of floating LNG installations is beneficial for: 

• Producers of natural gas 
• Liquid natural gas plant operators 
• Offshore industries 
• Inshore FSRUs 
• Floating LNG 
• Researchers of design and new technologies for floating LNG 
• LNG marine transportation 

Why should you use ISO 20257-2- Design of floating LNG installations? 

A floating storage regasification unit (FSRU) is a vital component required while transiting and transferring liquefied natural gas (LNG) through the oceanic channels. Therefore, FSRU can be termed as a special type of ship used for LNG transfer. 

ISO 20257-2 describes the specificities of the FSRU BOG handling and recovery system. ISO 20257-2 fulfils the specific requirements for recondenser. The recondenser has two purposes: 

• Recondensation of the BOG into the sub-cooled LNG stream from LP pumps 
• Feeding the LNG HP pumps with liquid and providing liquid hold-up capacity between the LP and HP pumps 

ISO 20257-2 states the functions of HD and LD compressors. ISO 20257-2 assists the user with combined vaporizers and ambient air vaporizers. 

ISO 20257-2 is applicable to offshore, near-shore, or docked FSRUs and to both new-built and converted FSRUs.  

Overall, ISO 20257-2 is helpful as it assists the user with FSRU issues. FSRU warms up LNG for regasification and sends it out as high-pressure according to the user’s demand.
