PVV_According to TOTAL referential, for new installations, which type of tank shall be selected for the storage of LNG (multiple answers possible)?
Single containment tank
Double containment tank
Full containment tank
Membrane tank
PVV_Which of the following material is suitable for LNG cryogenic services (multiple answers possible)?
Austenitic stainless steel type 304L (e.g. PMC B46)
Duplex stainless steel type UNS S31803 (e.g. PMC B70)
Low Temperature Carbon Steel type ASTM A333 Gr. 6 (e.g. PMC B21)

Coil Wound Heat Exchanger
Shell & Tube Heat Exchanger
Block-in-Shell Heat Exchanger
PVV_For what purpose are bi-metallic transition joints used in LNG applications?
Because it’s fun and very expensive
To allow a welded connection between two different materials such as stainless steel and aluminum
To ensure an electrical discontinuity between two different materials
To have an hybrid metallic component combining the properties of two different materials
