The estimation of these costs is based on the performance criteria of each failure mode for the structural and hydraulic responses related to the design limit stages SLS and ULS, including both a physical measure and a probability of occurrence, ROM 0.0 and 1.0 (2000 and 2007) and PIANC 2017. To evaluate these costs including their uncertainty it is necessary to apply, (1) a spatial and temporal damage evolution model of each failure mode, (2) to define the interdependence between modes including the decision criteria when start to repair, and (3) to compute the costs depending on the real sea conditions, the strategy of construction and the available construction power. The main objective of this work is to present a methodology to estimate the probability distribution function of the investment costs in the useful life of the structure.}, number={36}, journal={Coastal Engineering Proceedings}, author={Folgueras, P. and Del-Rosal-Salido, J. and Moragues, M.
