scope:
Under this service specification, risk assessment means the systematic identification and evaluation of hazards to personnel and plant (see 102).
Risk assessment is the overall process of risk (hazard) identification, risk analysis and risk evaluation. The results of the assessment identify areas of most significant risk and enable risk reduction measures to be targeted where most effective.
The use of risk assessment for classification shall include:
a) Hazard identification and evaluation of hazards and the risks they pose to safety and integrity on the installation.
b) Demonstrating that the risks are acceptable, i.e. meet agreed risk acceptance criteria and or target risk reduction.
c) Identifying the safety-critical elements and their required performance standards that are required in order to meet the acceptance criteria.
In order to assign classification, DNV will review and approve the selection of safety-critical elements and performance standards, and verify their design, construction, installation and commissioning.
DNV will establish an installation-specifi
Maintenance of class shall be through ongoing verification that the safety-critical elements remain in adequate condition and repair to foreseeably meet their performance standards.
Whilst classification is maintained, DNV will retain the verification scheme under review based on findings of verification activities. DNV will issue an annual verification status report, which may be used as documentation with other regulatory review requirements.
Classification in accordance with this specification indicates that the installation has been verified as attaining, and should foreseeably continue to attain, an acceptable level of safety and integrity as specified by agreed risk criteria. The owner or operator is responsible for ensuring compliance with requirements of maritime administrations or conventions, and for seeking concessions where any such requirements are not fulfilled.
