The negative result or effect of an event. There may be a range of possible impacts associated with an event. (only negative effects are considered here)
A measurable characteristic, element or variable that can cause a risk to occur.
A constituent of risk, which is identifiable upon risk occurrence and its presence denotes the occurrence of the risk.
The sequence of the driving forces that result to the occurrence of a risk. Risk occurrence is the result of relations of events, processes conditions and system reactions that all together constitute a risk occurrence mechanism.
Probability of occurrence of a risk (quantitative terms)
The negative result or effect of an event presented in quantitative terms. There may be a range of possible impacts associated with an event. (only negative effects are considered here)
Dynamic and repeated (cycling) loading due to winds and waves may lead to the development of microcracks of defects that cause localized stress concentrations. These microcracks may grow or propagate without any appreciable deformation of the structure. Consequently, gradual loss of the resistance of the support structure and/or the tower and/or the RNA occurs combined with the existence of cumulative damages on the various parts of the OWT (Fatigue mechanism).
replacement cost of the tower and the RNA and/or of the whole OWT
Risk of replacement cost due to normal wind and wave conditions in power production situations
Risk of injuries due to normal wind and wave conditions in power production situations
Combination of normal (return period of 1 year) wind and wave loads in power operation situation
Risk of failure due to normal wind and wave conditions in power production situations
Risk of loss of revenue due to normal wind and wave conditions in power production situations
Risk of Repair/maintenance cost due to normal wind and wave conditions in power production situations
Repair/maintenance cost of the support structure and/or of the tower and/or of RNA
