STORMLAMP – STructural behaviour Of Rock Mounted Lighthouses At the Mercy of imPulsive waves

The Vibration Engineering Section is pleased to announce that the Engineering and Physical Sciences Research Council (EPSRC) will fund a research project STORMLAMP – STructural behaviour Of Rock Mounted Lighthouses At the Mercy of imPulsive waves.

Rock-mounted lighthouses play a vital role in safe navigation but, like other critical infrastructure, their longevity is threatened by extreme weather. Virtual navigational aids such as GPS are fallible and mariners will continue to need physical visual aids. The loss of any reef lighthouse will be incalculable in terms of safety, trade and heritage.

STORMLAMP combines field, laboratory and mathematical/computer modelling methods to assess six of the most vulnerable rock lighthouses in the UK and Ireland and will move to a focus of one lighthouse for the following two winters.

Field instrumentation and procedures will be developed by the University of Exeter (James Brownjohn and James Bassitt) for the highly challenging constraints. Meanwhile, UCL (Dina D’Ayala will create test data guiding of multi-scale numerical simulations for lighthouses that can be used with the full-scale data to diagnose observed performance in the long term monitoring.

These models will link with advanced physical and CFD simulations by Plymouth University’s COAST Laboratory (Alison Raby-who leads the project- and Deborah Greaves).

Based on these modeling exercises, the long term monitoring of a single structure will used to characterise the wave loading in-situ at full scale. The project will support performance management of such structures worldwide.

Total EPSRC funding is £1.03m, with £173k to Exeter, and the project runs from 1st April 2016 to 30th September 2019.
