Optoma EX785 Projectors from the ProScene Range Provide Dynamic Solution for The English Heritage’s New Attraction at Dover Castle “Operation Dynamo: Rescue from Dunkirk”

Challenge: To update the visitor experience as part of a guided tour through the Napoleonic tunnels at Dover Castle, focusing on their use during World War II. The main challenge was using a high degree of visual and audio interpretation without impacting on or detracting from the historical space.
Solution: Twenty-three Optoma EX785 projectors were installed in the main Dunkirk to Dover tunnel and three in other areas. Optoma was approached to supply the projectors for this project because they fitted specific demands for particular resolution short throw off axis projection whilst remaining in budget and offering a warranty for continuous operation.
Results: Visitors to the Napoleonic tunnels at Dover Castle have been provided with an eye-catching experience that offers a long synchronized AV experience for visitors to really become part of the attraction.

The Challenge

Background

On 10 June 2011, English Heritage opened the doors to their new attraction “Operation Dynamo: Rescue from Dunkirk”. The network of Secret Wartime Tunnels stretches 60m in length, twenty-six metres deep underground, behind the White Cliffs of Dover. Audiovisual technology is used throughout the eight zones to re-create the drama of the Dunkirk evacuation.The designer and producer of the new experience was Kvorning Design and Communication of Denmark. Electrosonic was the AV systems integrator on this project, working with Kvorning from the initial design stage, to help validate design ideas, until completion. A visit to the new Dover Secret Wartime Tunnel’s experience involves groups of up to 30 people being taken through eight zones containing original news-reels and recordings, two years of painstaking research, testimonies from veterans of both the beaches and the tunnels, and state-of-the-art special effects to deliver a vivid account of what Sir Winston Churchill called a “miracle of deliverance”.

 

The Challenge - High Impact Visual Experience

The main challenge faced by the designer was how to include a high degree of visual and audio interpretation without impacting on or detracting from the historical space. Rob Ferguson from Electrosonic was responsible for the initial design of this project, this included carrying out projection tests on site to ensure the project was feasible. The project executed by Rob Stallard, Senior Project Manager and Ed Osborn, Senior Engineer of Electrosonic.Many of the original tunnel features had to remain and be preserved. A great deal of new technology had to be installed without destroying any of the historical features of the tunnels and keep it aesthetically pleasing to visitors.Projecting onto a curved tunnel wall was another challenge which was overcome using twenty-three Optoma projectors edge-blended and with sides warped and straightened by a Dataton Watchout™ system. Staff working in the tunnel had to adapt quickly to the wet, dark, deep tunnels.
