Shiptime Maritime Archaeology Project Orkney – HMS Royal Oak Steam Pinnace Located

The HMS Royal Oak pinnace

The tragic story of the loss of HMS Royal Oak in the first weeks of the Second World War is well known in Orkney and further afield, but there has always been mystery surrounding the location of one of the small vessels that was used by sailors attempting to escape from the sinking battleship.

Orkney Research Centre for Archaeology (ORCA), the University of the Highlands and Islands Archaeology Institute and SULA Diving can now confirm the position of the missing HMS Royal Oak steam pinnace.

HMS Royal Oak was a Royal Navy battleship which was moored in Scapa Bay as an anti-aircraft platform to help defend a vital radar station on the cliffs. On the night of 13 October German submarine, U-47 manoeuvred into Scapa Flow and finding the Royal Oak at anchor fired torpedoes which led to the sinking of the huge ship. 834 men were lost of the 1,200 crew on-board with the few survivors struggling in the cold oil-covered water.

Research shows that two 50-foot picket boats were on onboard HMS Royal Oak when she was torpedoed. Number 749 was built by J Samuel White of the Isle of Wight and number 752 built by Rowhedge Ironworks, Wivenhoe Shipyard, Essex.

Documentary evidence indicates that around 100 crew members abandoned ship via her port side pinnace, which had a lifesaving capacity of 59. The Starboard side pinnace  went down with Royal Oak and can be seen on the seabed a short distance from the wreck. The small pinnace had not got up steam so boards were used to paddle the vessel away from the sinking Royal Oak.  The pinnace began to rock due to being overloaded and the chief buffer tried to counter the movement by shouting instructions ‘’Lean to starboard, lean to port’. Some on deck were ordered below to make more room as more men tried to climb on board.

Dick Kerr who was hanging on the side of the small vessel says, he heard someone start singing ‘Down Mexico way, south of the border’’ and a few others joined in. A short while later the pinnace capsized throwing those on deck into the water and trapping those who had gone below. Some crew scrambled onto the upturned hull but many were lost. The vessel then righted herself, capsized once more and then sank.

The location of this little ship was not known – until last month when the Shiptime Maritime Archaeology Project pinpointed the shipwreck on multibeam sonar, 300 metres from the main wreck site. The site was surveyed by Triscom Enterprise as part of the Shiptime Maritime Archaeology Project. The site had been previously side scanned by SULA Diving as part of a survey for OIC Harbours, but the identity of the craft had not then been established. As part of the project, a dive survey was conducted by SULA Diving of Stromness on the contact to establish that this was the missing port side pinnace.

Diver, Wayne Allen, of Wayne Allen Technical said, “It was a privilege to be able to assist SULA Diving in recording these historically important sites.”

Alistair Coutts, Business Development Manager, Seatronics, said: “Seatronics were delighted to have the opportunity to work with the collected specialists on this exciting project, providing ROV, positioning and 3D modelling and spatially cross referenced video inspection equipment”.

Pete Higgins, Senior Project Manager, Orkney Research Centre for Archaeology commented that, “ It is a great privilege to be involved with the monitoring of such an important wreck site as HMS Royal Oak and in the finding of the missing pinnace. The site will now be recorded and will add to our knowledge surrounding the sinking of HMS Royal Oak.”

This exciting project is led by Sandra Henry of UHI Archaeology Institute, ORCA (Orkney Research Centre for Archaeology), the University of the Highlands and Islands Archaeology Institute and Kevin Heath of SULA Diving who have brought together universities, commercial companies and government bodies including Historic Environment Scotland, Marine Scotland, Ulster University, Heriot-Watt University, University of Dundee, and Seatronics – an Acteon company.

Notes for Editors

  • The project lead is Orkney Research Centre for Archaeology (ORCA), University of the Highlands and Islands Archaeology Institute.
  • http://www.suladiving.com Provided the diving services. Side scan data acquisition and research for the project.
  • Marine Scotland vessel MV Scotia was the work platform for data collection. Data collection involved Marine Scotland undertaking MBES survey, providing calibrated unprocessed raw data and camera equipment for the acquisition of data.
  • Seatronics – an Acteon Company provided ROV, positioning and 3D modelling and spatially cross referenced video inspection equipment.
  • Historic Environment Scotland provided funding, guidance on marine historic assets, survey targets and specialist knowledge on the wreck sites.
  • Ulster University provided input into the specifications for data acquisition for the geophysical and ROV surveys and will provide input into maritime archaeological assessment and analysis.
  • Heriot-Watt University provided input into the specifications for data acquisition for the ROV survey and undertook marine biological studies on the submerged cultural heritage assets.
  • Ministry of Defence provided input into the specifications for data acquisition for the geophysical and ROV surveys, and specialist knowledge on the wreck sites being investigated and environmental studies of the wreck sites.
  • The University of Dundee will process MBES and ROV survey data and work to produce visualisations based on the collected data. This will involve the production of 3D models of the wreck sites from the multibeam echosounder and photogrammetric data.
  • The project was conducted under licence from the Ministry of Defence.
  • Thanks to Triscom Enterprises Limited. Triscom operates its own multibeam echo-sounder which is an advanced sonar system able to provide full-coverage seafloor mapping, which is mainly used in the nearshore construction & cable industry. We were delighted to be given the opportunity to provide our 3D mapping service in the recent marine archaeology project in collaboration with ORCA and Sula diving. The larger vessel involved in the project, the Scotia, was unwilling to risk close proximity with the wreck of the Royal Oak which rises to about 6m below the surface, but Triscom were able to rapidly mobilise a multibeam aboard Sula’s small workboat Challenger, and this gave us the opportunity to do a 3D scan of the newly discovered wreck of the Royal Oak’s steam pinnace.
