14 Part I Structural Design PrincipreS
The use of a "living" process that is flexible, strives for completeness, and can be easily
implemented,
The use of qualitative and quantitative risk measures;
The use of effective and efficient analytical methods, which provide results that are sound
and familiar to inspection personnel.
A risk-based inspection approach may be developed based on evaluation of structural
performance for fatigue/corrosion, fracture mechanics, corrosion engineering, structural
reliability and risk assessment.
1.4.3 Human and Organization Factors
Statistics shows that over 80% of the failures are initially caused by the so-called human and
organization factors. Figure 1.6 shows the interaction between the structure, human,
organization and management system. Human behavior, organizational culture and
management of HSE will all influence the structural safety.

1.5 Layout of This Book
Risk-based limit-state design, combining probabilistic methods with FEM-based structural
analysis, will be widely accepted and implemented by the industry for the cost-effective and
safe design and operation of marine structures. The purpose of this book is to summarize these
technological developments in order to promote advanced structural design. The emphasis on
FEM, dynamic response, risWreliability and information technology differentiates this book
fiom existing ones.
Figure 1.7 illustrates the process of a structural design based on finite element analysis and
riskheliability methods.
