The design temperatures are revised to "-155 F to -320
F".
Check if we need to provide the referenced API
standard for design temperature from -60 F to -155 F.
(Note: In the original API 620, App Q is applied to -60
F to -273 F and App R for +40 F to -60 F).
2)
In Section Q.2.2.1, "9% or 5% Nickel steel
shall be impact tested in accordance with Q.2.2.2
through Q.2.2.4, and Section Q6.2.
3)
In Section Q.3.2, suggest to keep
the original text, since the text is considered as a
general statement, and good reference.

In Section Q.4, suggest not to delete this
section, but referred back to API RT Section 6.xx.
5)
In Section Q.5.2, suggest to add "API RT
Section 6.x.x" as reference for design load
combinations.
6)
Section Q.10.
a)
Add "API RT Section 6" as a reference for
foundation design.
b)
Add brief description of pile-supported
foundation in the Section, since App C is referred to
design consideration of soil-supported foundation, and
also most of the LNG tanks are designed to be pilesupported.

Shouldn't we allow other liquids? "Add such" as before
ethane, ethylene, and methane.
It would be helpful to refer speically to "diagrams of
containment configurations" in API 625.
Change RT to API 625.
Q.1.1 GENERAL
The provisions in this appendix
form a guide for the materials,
design, and fabrication of tanks
to be used for the storage of
liquefied gas such as ethane,
ethylene, and methane.
This appendix together with the
basic sections of API 620 provide
requirements for the materials,
design, and fabrication of the
metallic portions of a cryogenic
