See what it takes to sound the foghorn at Sumburgh Lighthouse on Shetland Island in Scotland. In this video, lighthouse engineer Brian Johnson starts up the three Diesel Kelvin engines, powering the compressors that power the foghorn.
He sounded the beautifully renovated foghorn for the first time since 1987. Filmmaker JJ Jamieson documented the wonderful mechanical process that engages the gears to sound the horn.
The Sumburgh Head Foghorn was restored and re-painted, the bright red trumpet points out to sea as it has since it was built in 1905 and put into operation in 1906. …the Foghorn was last sounded in 1987, but will now sound again on special occasions.
