“…A century earlier, the Eddystone lighthouse, which was designed by Smeaton, had three crucial details to overcome wave action, which would be incorporated into the designs of Walker and Douglass. These were: a curved concave profile, 16 sector stone blocks for each ring and the dovetailing of the stone blocks fixing the sectors into each other, to render each course monolithic [8]. Wolf Rock was ultimately designed with a variable number of sector stone blocks per ring, ranging from 16 blocks for the lower rings to nine blocks for the upper ones.…”

Lighthouses situated on exposed rocky outcrops warn mariners of the dangers that lurk beneath the waves. They were first constructed when approaches to wave loading and structural response were relatively unsophisticated, essentially learning from previous failures. Here, we chart the evolution of lighthouses on the Wolf Rock, situated between Land's End and the Isles of Scilly in the UK. The first empirical approaches are described, followed by design aspects of the present tower, informed by innovations developed on other rocky outcrops. We focus on a particular development associated with the automation of lighthouses: the helideck platform. The design concept is described and the structure then scrutinized for future survivability, using the latest structural modelling techniques of the entire lighthouse and helideck. Model validation data were obtained through a complex logistical field operation and experimental modal analysis. Extreme wave loading for the model required the identification of the 250-year return period wave using a Bayesian method with informative prior distributions, for two different scenarios (2017 and 2067). The structural models predict responses of the helideck to wave loading which is characterized by differential displacements of 0.093 m (2017) and 0.115 m (2067) with associated high tension forces and plastic strain. This article is part of the theme issue ‘Environmental loading of heritage structures’.

“…He was consulted frequently by the harbour authorities in the following years, but was only appointed as Surveyor and Civil Engineer to the harbour on a formal basis in 1787. 4 On the death of the great man in 1792 the harbour trustees doubted whether they should appoint a successor. Wyatt was not appointed permanently to the post until 1794.…”

Architectural History

Samuel Wyatt (Fig. 24) is best known as an architect of elegant Neo-Classical country houses. This has overshadowed the fact that he was also an engineer of considerable ability, a member of the Smeatonian Society of Civil Engineers and a Fellow of the Royal Society. Some light has been thrown on this aspect of his career by recent research into the Albion Mill, particularly Professor A. W. Skempton's article on the subject in this journal recently. Wyatt's talents as an engineer and as a distinguished Neo-Classical architect are both expressed in the buildings he designed for Ramsgate harbour between 1794 and his death in February 1807.
