Faslane Nuclear Submarine Jetty

Faslane Nuclear Submarine Jetty

Dynamiq Engineering have recently completed both Seismic Analysis and Explosion Analysis for a range of transformers used to supply power to the new floating jetty at the Faslane Nuclear Submarine Base.  The 200m long reinforced concrete jetty will provide berths for six new Astute-class submarines at the Royal Navy's Faslane Base.  The Valiant Jetty will be kept in place by four piles at its corners, each as tall as Nelson's Column, allowing it to rise and fall with the tide.

 

Five tugs towed the structure on its nine-mile journey from Greenock.  The £150m jetty, built by Amec and Morgan Est at the Inchgreen dry dock, weighs 44,000 tonnes, making it twice as heavy as a typical aircraft carrier.  Its hull is composed of 12 watertight cells, running its whole length, with concrete walls half a metre thick.  At each end, a heavy steel "forepeak" provides a mooring for the submarines.  The floating design was necessary because there is a 3m tidal range on the Gare Loch.
