New documentary marks anniversary of naval disaster
Published on 14 October 2020
The anniversary of one of the Royal Navy’s largest single losses of life has been marked with a special documentary produced by University of Dundee experts.
Staff from the University’s Duncan of Jordanstone College of Art & Design used 3D imagery to map the wreck of HMS Royal Oak, which was sunk with the loss of 835 lives after being torpedoed while at anchor at Scapa Flow in 1939.
To mark the 81st anniversary of the sinking, Professor Chris Rowland and Kieran Duncan, from Dundee’s Communication Design course, have incorporated those images into a new documentary, “Fallen Oak”. The piece charts how a small international team of volunteer civilian divers have utilised the highly-specialised visualisation technology to document the wreck.
“Documenting this historic ship has been a highlight of my experience in shipwreck visualisation,” said Professor Rowland.
“The international team involved videographers, photographers and experienced technical divers to capture the condition of the wreck after 80 years underwater. The results, some of which are highlighted in this documentary, reveal in detail the key features of the wreck and bring new information to the historic record.”
Constructed in 1914, HMS Royal Oak saw combat at the Battle of Jutland during the First World War and in peacetime served as part of the Atlantic, Home and Mediterranean fleets.
While still in service, she was considered obsolete as she was anchored off the Orkney coast on October 14 1939. However, she remained home to some 1,234 sailors at the time of the daring German attack, but took just 13 minutes to sink after being struck by torpedoes. Of those who lost their lives, more than 100 were teenage boys.
Today, the site is a designated war grave and special permission was granted by the Secretary of State for Defence to a team led by Emily Turton and Ben Wade of the Orcadian dive boat “Huskyan” to document the last resting place of those who perished. The project is part of a collaboration with the Royal Oak Association and the Royal Navy and aims to ensure that HMS Royal Oak is not forgotten, by sharing the gathered imagery with relatives of those lost, as well as the wider public.
As part of its contribution to the project, the Dundee team has created 3D visualisations of the wreck using a combination of 3D photogrammetry and multi-beam sonar data. The multi-beam image is produced by collecting millions of sonar “pings” transmitted from and to a survey boat that travels over the wreck. This was used as 3D map of the wreck to which much higher detailed photogrammetry details were added.
