Purpose and goal
The aim of CliMaint is to ensure robust and reliable railway infrastructure by maintenance adaptation to climate change. The objective of the project is to reduce future disturbances due to extreme climate conditions by effective maintenance program. The objective will be achieved by utilizing RAMS (reliability, availability, maintainability and safety) methodology and integrating infrastructure degradation modelling with metrological and satellite information.
Expected results and effects
CliMaint research activities, including (WPs, Tasks, and Deliverables) are completed as per plan. During project the following outcome have been achieved: Better understanding of causal relationship between extreme weather events with railway infrastructure failures, Integration of the established infrastructure and climate prediction models, Increase the level of awareness through various activities including workshop, webinar,etc. Better collaboration with TRV regarding climate impacts on infrastructure.
Planned approach and implementation
A literature review, two questionnaire studies, interviews and a one-day workshop have been performed. In addition, for the analyses various data including, failure data, traffic, satellite and meteorological data have been collected for duration of 18 years. Furthermore, potential prediction models have been identified. PHM has been selected for assessing climatic parameter impacts and risk analysis have been conducted to identify the most vulnerable asset. Finally, life cycle cost (LCC) analyses have been implemented to estimate the LCC trend induced by climate change.
