Scapa Flow underwater heritage investigations

HY 20190 26414 (HY22NW 8001), ND 36212 97158 (ND39NE 8045), ND 16083 98741 (ND19NE 8004), HY 43491 05253 (HY40NW 8001)

Multi-disciplinary survey project involving recording of the wrecks of the German High Seas Fleet in Scapa Flow, and the wrecks of the Royal Navy vessels HMS Hampshire, HMS Vanguard, HMS Pheasant and HMS Royal Oak in order to gather data to increase knowledge and understanding of the extent, survival and character of submerged cultural heritage remains located on the Orcadian seafloor.

The survey project was conducted on two vessels a) aboard the Marine Scotland survey vessel MV Scotia, using drop keel-mounted Teledyne ResonSeabat 7125 multibeam sonar, drop camera and Predator II inspection class Remote Operated Vehicle (ROV); and b) sidescan sonar and diving inspection aboard MV Challenger.

The project was led by Sandra Henry of ORCA Marine, University of Highlands and Islands in collaboration with a wider consortium of organisations, including universities (Ulster; Heriot Watt; Dundee), private companies (Sula Diving;Seatronics;Triscom Marine Ltd) and public authorities (Marine Scotland; MoD; Historic Environment Scotland). The project also benefited from community volunteer input.

Further projects conducted by partner institutions are ongoing or being planned to utilise the data captured during this project.

Event	Type	Subtype	Notes	Date
1173726	RECORDING	SIDE SCAN SONAR SURVEY	Sidescan sonar survey was conducted on the wreck of HMS Royal Oak, and a geophysical anomaly 250m to the south-west. The survey was carried out from MV Challenger using a C-Max CM2 sidescan. Analysis of the data for the Royal Oak clearly shows the rudders and prop shafts on one of the sonar runs to the north of the wreck, and to the south, the damage to the bow and superstructure on the seabed is clear.

1172889	RECORDING	MULTI BEAM SONAR SCAN	Multibeam sonar survey on board MV Scotia (2017) recorded the remains of the Sms Brummer. The data was partially processed by the 3DVisLab, University of Dundee. Comparison of this data with data gathered in 2006 (by ADUS) provides evidence of deterioration over an approximately ten-year period. Changes include rotation of the hull mid-section, most likely due to deterioration of the deck which can no-longer support the weight of the hull. In 2017, the bow has collapsed and the deck structure further aft has peeled away . Diver observations in 2021 indicated that the condition of this section has deteriorated further. The stern deck of Brummer had fallen away and separated into broken sections by 2017 resulting in the stern hull rotating towards the seabed with the rudder no longer suspended in mid-water.

1173745	RECORDING	DIVER INSPECTION	One dive was undertaken to evaluate a geophysical anomaly lying approximately 250m to the south-west of the Royal Oak. Upon investigation, this anomaly was identified as a small wooden vessel of a pinnace or picket boat design. The wreck was lying upright in approximately 28m water depth. The bow section was well preserved. Records indicate that a steam picket boat drifted away from the Royal Oak carrying survivors from the torpedo attack, but subsequently capsized and sank as it was overloaded. It almost certain that the wreckage examined on this survey was the remains of that vessel. [...]	28 July 2017
