Why Risk Management
● Significant cost
● Demanding technical solutions
● Stringent time schedule
– Prevent unforeseen events through extensive and systematic identification and analysis of risk

Several different uses of “risk”:● Common use: Risk = Consequence & Probability
● Increased use:Risk = Consequence & Uncertainty
Uncertainty due to lack of knowledgeRisk Management and Technology Qualification

Uncertainty due to lack of knowledge
Example - ship collision● Life time of bridges will be
100 (200?) years● How will ships develop in
this period:– Fewer or more ships?– Smaller or larger ships?– Ice strengthened ships?– Autonomous ships?
● How to agree upon accidental loads for bridge design?

Risk treatment
● One of the project’s major risks concerns the (unanticipated) failure of new technologies
● Black swan type of risk – are there loads affecting our constructions that we are not aware of (at present)?
● Systematic approach needed
= Technology qualification.

Definitions
Definition (preliminary) oftchnology qualification in NPRA:
● TQ: The process of providing evidence that the technologywill function within specifiedlimits with an acceptable level ofconfidence (DNV-RP-A203, 2011)
● «Prosess for å demonstrere at et brukonsept vil tilfredsstille nødvendige krav under gitte grensebetingelser og med en akseptabel grad av tillit».
