The safety assessment process provides a rational basis for the assessment of the safety
of a craft by applying basic objective requirements for craft functions and for those
systems installed on board the craft that perform these functions. Moreover, specific
requirements are generated in the assessment process where the risk associated with
particular failure conditions warrants this.
The present part is organized as follows:
A brief summary of the underlying probability concept and some basic definitions are
given in chapter 1 below. Safety of WIG craft must be ensured throughout the entire
service life. The processes and methods employed vary in the different phases of the
life cycle and are accordingly grouped in two separate chapters: safety assessment for
craft systems and safety management covering the operational phase.
The first, described in chapter 2 (Safety assessment for WIG craft systems), constitutes
a thorough assessment of potential failures and the outcome of potential failures
occurring alone or in combination. It covers the phases from initial design to
commissioning of the craft. The second, described in chapter 3 (Safety management), is
primarily concerned with the operational phase of the craft and seeks to ensure safe
management and operation.
