Jersey marina storm gate overhall

Elizabeth Marina's storm gate and entrance is being worked on causing some restrictions

A major works project on the removal and essential structural survey of the Elizabeth Marina storm gate in St Helier, Jersey is currently taking place. The storm gate was installed in 1998 and acts as a protection mechanism, allowing the tidally-restricted Elizabeth Marina to ‘close’ during periods of inclement weather and rough seas, reducing the effect of stormy conditions within it. The gate locking mechanism failed during a routine operation in November 2018 causing it to lower unexpectedly due to the increasing water pressure load on it from the incoming tides. During this event the gate sustained some damage and as a result it was taken out of service pending these upcoming works, although in the meantime, Ports of Jersey have put mitigation measures in place. The storm gate was removed in mid April and the work is expected to take up to three-weeks to complete and in two stages, the first being its removal and transportation to the New North Quay for inspection and cleaning, with an underwater inspection of the gate’s entrance and mechanics by divers planned. The second stage will see a structural survey on the gate itself, followed by a decision on whether it can be repaired or will need to be replaced. Ports of Jersey added ‘Whatever the outcome, the existing storm gate or a replacement will not be installed in Elizabeth Marina until later in the year, after the main boating season has ended.’ The marina will be closed to marine traffic at certain times to maintain safe operations, with some areas of the promenades on the southern and western side closed to the public during the works. Commenting on the project, Jersey Harbourmaster, Captain Bill Sadler, said, “We are very pleased that this project represents a big step in addressing the longstanding issues associated with the Elizabeth Marina storm gate. The nature of the works does mean there will be some unavoidable periods of disruption to marina operations so that works can be conducted safely.” Boaters will need to note a depth reduction at the marina entrance (approx. 2.5m above the existing cill) during works, resulting in a smaller tidal access window. Further details of closures are available via ‘Notice to Mariner’ updates, navigational warnings through St Helier VTS and live updates/timings and FAQs on the Ports of Jersey website.
