Abstract
The design of topsides against explosions requires the definition
of a design over-pressure, however, these values are often treated
as deterministic and there is a wide variation within the industry
in the treatment and interpretation of the loads. This paper advocates
the adoption of a number of limit state for explosion loading. Events
of different magnitudes are differentiated on the basis of frequency
and linked to appropriate degree of reliability thus avoiding disproportionate
effects from minor events. The two principal limit states considered
are a limit state for all the safety critical systems for relatively
high frequency events and a survival condition for low probability
events. Parallels are drawn from other branches of engineering where
extreme loads have to be designed for.
