TABLE OF CONTENTS The introduction (Chapter 1) shows how structural safety in design can be focused on the premise that safe manufacturing, safe maintenance and safe operation are given. However, it is also shown that safety depends on the inspection quality in such a way that only after a detailed definition of the inspection programs is available, can the "true" detail design constraints and criteria be created.
Innovation often comes with the need for "Design under Uncertainty," which in turn causes requirements for a "Control process" that monitors service and inspection data and reduces uncertainty, updates "a priori" decisions (see Congdon, 2001 and Kullback, 1968) and uses the inspection programs to maintain "Level of Safety" (manages risk). Figure 2.16 illustrates how the risk management, monitoring and updating interacts in service (e.g. due to updating new data).
The "Extended Design Process" that includes consideration of inspection methods, provisions for uncertainty reduction, updating and continued safety monitoring during service would contribute significantly to safety.
