RE: why 21% for fire case
This has been discussed many times, however:
You have to consider that the RV is "the last defence". The main protection agains overpressure should be deluge and/or blow down.
The main purpose of the RV is to prevent escalation of the accident and risk to firefighting people. The vessel is considered "lost". When you dont have to consider that the vessel will go back into serve right after the overpressure scenario then using the design margin "a little more" is OK.
