UK DIO completes upgrades to Royal Navy Northern Ammunition jetty

The Defense Infrastructure Organization (DIO) has finished a set of improvements for the British Royal Navy’s North Ammunition Dock at Glen Mallan in Scotland.

The Northern Ammunition Jetty was modernized by construction engineering company VolkerStevin under a £67m contract awarded by DIO in 2019.

It is the final refurbishment of the jetty in support of the UK’s £7 billion Queen Elizabeth Class (QEC) aircraft carrier programme.

In addition to VolkerStevin, DIO also worked with managing agent Jacobs, who provided engineering and professional services for the jetty, as well as designer Arch Henderson.

The jetty is used to load and unload ammunition for the UK Navy’s surface fleet.

It was last updated in the 1970s and had reached the end of its useful life.

The latest upgrade work was carried out to extend the jetty’s lifespan by another 50 years.

The British Royal Navy noted that the previous jetty was demolished and replaced with a new 135m long jetty structure. A total of 127 steel piles were required to build this structure.

Other improvement works include the installation of navigation aids and five mooring dolphins. These units are connected to the Northern Ammunition wharf by a pedestrian access bridge.

Additionally, two modular fender spacer units have been placed in front of the new fender panels as part of the upgrade work.

DIO Project Manager Craig MacDonald said: “It has been a great pleasure working on such an important and dynamic national project.

“The project has faced numerous challenges, but they have been overcome with good teamwork, communication and collaboration. It is fantastic to see this vitally important facility now fully operational.”

The jetty was handed over to its operator Defense and Support Teams (DE&S).

VolkerStevin Managing Director John Cox said: “We are very proud to have played a key role in the successful delivery of all three phases of the Queen Elizabeth-class carrier infrastructure upgrade programme.

“The completion of this final phase is testament to the hard work and commitment of the entire team and demonstrates the benefits of a strong collaborative approach in delivering complex critical infrastructure projects.”
