Safety Margins and Design Margins: A Differentiation between Interconnected Concepts

Task Group on Safety Margins Action Plan (SMAP), Safety Margins Action Plan - Final Report

The OECD is a unique forum where the governments of 30 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisati...

Understanding the Relationship between Design Margins and Trade-offs

Margins of safety in FPSO hull strength

Recent studies were carried out to determine the variation in safety factors (between the applied loading and the capacity) of FPSOs currently operating in the UK Sector of the Central North Sea, and designed using either a class rule type approach or a more advanced hydrodynamic – FE type approach. Results from these studies seem to indicate that the safety factor in both cases is similar, sin...

Safety Margins for Flight Through Stochastic Gusts

W IND disturbances are a common factor in aviation accidents. Among 126 airplane accidents that occurred between 1979 and 2009 involving loss of control in flight, 14% listed windshear, turbulence, or thunderstorms as a cause or contributing factor. Moreover, 86% of the accidents initiated by atmospheric disturbances led to an upset flight condition, which usually entails an excursion of the ai...

Margins are more important than text, Historical values of margins, memorial notes and colophons of Manuscripts in Zoroastrian tradition

In the Zoroastrian tradition, the most important challenge and the most ambiguous issue is ambiguity in history and neglect of time and chronology. Perhaps, this approach that historical time is limit and the begging and end of time is clear and the goodness will be conqueror eventually; it is because of ambiguity of history in Zoroastrian tradition.since early time to now, the Zoroastrian re...
