The redevelopment of the Glen Mallan jetty in Scotland, UK, will support the Royal Navy’s surface fleet in loading and unloading ammunition. The Defence Infrastructure Organisation (DIO) is investing £64mln in a redevelopment of the Northern Ammunition Jetty.

The jetty is used to load and unload ammunition. The original jetty was last upgraded in 1970 and had reached the end of its natural life. The rebuild will allow continued use by the Royal Navy’s existing vessels and make it suitable for the new aircraft carriers. The infrastructure works are expected to provide a design life of up to 50 years.

Contractors VolkerStevin are undertaking the project with completion planned for 2021. All waste from the jetty demolition has been transported on barges to recycling facilities on the Clyde and will be reused for construction. The project team has also installed 97 jetty head piles into the seabed to support a reinforced concrete deck for the new jetty. The jetty head piles will support a reinforced concrete deck for the new jetty.

The works also include the installation of five mooring dolphins, connected to the jetty by a pedestrian bridge, and two of these piles for the mooring dolphins have been installed. Two modular fender spacer units will be placed in front of the new fender panel and will move with the tide to prevent the Queen Elizabeth Class aircraft carriers’ overhanging flight decks from colliding with the jetty.
