| Description | Forced vibration using a 'shaker' enables identification of at least the fundamental modes of vibration. Where there is a helideck, there are up to 4 'fundamental' modes, in two directions and with different phase with respect to the masonry structure. Helidecks modify the modal mass, a key parameter controlling the response to external horizontal loads. For Wolf Rock, the identified modal parameters provide a means to estimate the breaking wave modal impulses. Monitoring data for the 2017/2018 winter storm season corroborate wave tank data on extreme loads. Fastnet's extreme wave climate shows no statistically significant effects of due to the climate change. Lighthouses are not affected by direct breaking wave loadings but by broken wave impacts - intensity is reduced but duration is increased, compared to unbroken wave. Wave load does not vary linearly with breaking distance - depends on whether the wave can regenerate after it first breaks, so depends on precise bathymetry. Impulsive force is always larger than the quasi-static force. Force laboratory data can be effectively analysed by means of seismic analysis techniques such as deconvolution and Duhamel integral. Structural response of lighthouses due to waves is governed by uplift and rocking. DEM and FEM with contact interfaces between discontinuous blocks successfully used for modelling extreme wave impacts. Limit analysis used for assessing failure using Python code used on 6 lighthouses - size, shape, density, and height above the sea level were found to be crucial. The vulnerability of the lighthouses, in combination with extreme wave hazard can be used for prioritising the detailed analysis and structural assessment. |

Research images of Fastnet lighthouse have appeared in Pioneer, the EPSRC blog. At University of Plymouth Research Festival 2020 a Quick Fire talk related to project research was delivered at Understanding the marine environment for a sustainable ocean economy: 'Storm waves and winds bring destruction alongside the promise of renewable energy'. At UCL Civil, Environmental and Geomatic Engineering Dept, an internal lecture and workshop on research related to the project will be delivered. Research cards and posters were sent to: SPAB, South Foreland Lighthouse, Historic England, Assoc. of Lighthouse Keepers and ICE Plymouth. An end of project workshop is scheduled for May 2020. The working title is: Monitoring and Modelling: Maritime Structures under Environmental Loading. An article will be produced for Flash journal, the Trinity House magazine.
