Portsmouth Harbour is all set to light the way for aircraft carrier HMS Queen Elizabeth when she comes home for Christmas later this month, say BAE Systems.
The company say that the 15 mighty navigational aids, which stand up to 30m tall, clearly mark the deep water channel specially created to enable the carrier to safely navigate her way back to Portsmouth Naval Base.
“To make sure the solar and battery-powered lights on top of the navigational aids are shining brightly whenever HMS Queen Elizabeth enters or leaves the harbour, regular maintenance is critical. And that’s where the BAE Systems’ divers come in.”
“We were asked if we could assist in the maintenance of the navigation aids and we were only too happy to help,” said Diving and Maritime Co-ordinator Jim Lynch.
“The team check the condition of the solar panels and batteries, ensuring they’re clean, free from guano and salt build up, and that the battery terminals are operating effectively. We carry out planned maintenance on a six-monthly basis as well as regular checks to ensure they’re fully operational.”
Diver Ed Ellis said he and his colleagues’ day jobs are usually spent inspecting and maintaining almost five miles of sea walls around the historic naval base, including jetties, quay walls and berthing facilities as well as centuries-old culvert systems and service tunnels, so maintaining the navigational aids is quite a change of direction – literally.
“It’s one extreme to the other but we all enjoy a challenge – although it can be a bit nerve-wracking as the platforms at the top of the aids can sway by up to a metre so we can only work on them at winds up to 17 miles an hour,” he added.
This will be HMS Queen Elizabeth’s fifth entry into Portsmouth Harbour in the safe hands of expert pilot Tony Bannister, who will be standing alongside new Captain Nick Cooke-Priest on the ship’s bridge to help make sure the carrier, the largest ever operated by the Royal Navy, stays on course.
