NORSOK N-001 Structural Design
• Limit state design method
• Limit state:
This term refers to a state of the structure where the structure or a
part of the structure no longer fulfils the requirements ensuring that
the structure performs according to the design specifications.
• Limit state conveniently controlled by an equation on the form:
Permanent loads
Variable loads

• Fatigue Limit State (FLS)
Important limit state ensuring a proper margin against fatigue failures.
Limit state formulation:
Fatigue Life Calculated > nf * Structural Design Life
nf = 1, 2, 3 or 10 depending on severity of a fatigue failure.
10 is used for cases with large consequences which additionally is
difficult to inspect.
NB! If a safety factor of 10 is found for a detail where inspection can
be made, one can not skip inspections.
75
NORSOK N-001 Structural Design
• Accidental Damage Limit State (ALS)
The purpose of the accidental damage limit state is to ensure that a given
accidental scenario does not lead to a complete loss of the integrity of the
structure.
Partial safety factors are in most cases set equal to 1.0, the characteristic
accidental load shall correspond to an annual exceedance probability og 10 -4,
and the capacity used may utilize plasticity and system effects.
Minor local damage is permissible within ALS.
In damaged condition, structure shall withstand 10-2 – annual probability
enviromental loads.
For Norwegian Continental Shelf, rare environmnetal loads (10-4 – annual
probability loads) shall be used in controlled using the accidental limit state.
