Trident Securi-Mesh system / Trident Xtreme 3XM
BAE Systems required security solutions at four sites at Portsmouth Naval Base including Princess Royal Jetty, the shared border with the historic HMS Warrior 1980, an iconic Harrier Jump Jet display and the base’s main entrance at Trafalgar Gate.
BAE Systems identified Jacksons Fencing to provide high-security and access solutions at a number of locations on the naval base, including end-to-end specification and installation of onsite fencing, without the need for third party involvement. The project called for Jacksons Fencing’s expertise as the site houses extremely valuable defence assets and is a lively operating base for 120,000 visitors annually and 15,000 daily workers.
• Princess Royal Jetty
Princess Royal Jetty needed to be secured from the rest of the base. Jacksons installed 440m of its Trident® Securi-Mesh® System as well as one large sliding gate, five manual double-leaf swing gates and six turnstiles. To maintain the integrity of its protection capabilities, the fencing system is overlapped by a minimum of 75mm at the posts. It has clamp bar fixings to provide additional resistance to penetration attempts, and an anti-climb design to prevent potential intruders from bypassing the perimeter from above. Jacksons completed the works in time for the new aircraft carrier to set sail from its new home dock in Oct 2017.
• Trafalgar Gate
At Trafalgar Gate, the main entrance and pass office to the naval base, the existing fencing needed to be replaced. Jacksons installed 220m of Trident® Securi-Mesh® System fencing as well as turnstiles as part of this refurbishment.
HMS Warrior 1860 at Portsmouth Historic Dockyard is open to the public and tourists, who are welcomed aboard for an interactive, historical and educational experience. The publically-accessible site has a separate entrance at the Victory Gate and shares a beach border with the off-limits Naval Base. Consequently, high-quality fencing was required to ensure that the barrier between the general public areas and the Naval Base was not penetrable.
Jacksons' Trident® Xtreme 3XM was installed on the beach and ran out into the sea. It was double galvanised and marine powder-coated black to ensure it was protected from the elements. The Trident® Xtreme 3XM system was chosen because it provides an immensely strong and rigid structure. It has vertical bars featuring a fully welded tubular stopped pale-through-rail construction with horizontal railed sleeved on to the upright posts with concealed fixings. Pale-through-rail design adds strength to the fencing and ensures that no bolts or palings can be removed or prised apart. The combination of its closely spaced pales, substantial wall thickness and novel cut-delay technology, is designed to frustrate and deter attempts to penetrate the fence. It provides good visibility which aids surveillance tools and incorporates anti-climb design.
• Harrier Jump Jet display
An iconic and out-of-service Harrier Jump Jet which played a valuable role for the Royal Navy for more than 30 years, is also housed within the Portsmouth Naval Base and is not accessible by the public. In order to protect this asset, Jacksons installed a pedestrian guardrail around the jet helping to showcase the display without intruding on its appearance.
