Dave, thanks for the interesting history along with the photograph. As she was 34,000 DWT I'm not surprised that she left a rather large oil slick on sinking being fully loaded. Her Greek owners were a one ship outfit called Don Shipping Co. Ltd. (Athens), who seemed to disappear after she floundered so maybe your theory is correct although all the information I could find attributes her sinking to "hull structural failure". The exact cause seem very vague and in some oil spillage tables I have seen the "structural failure" is followed by a "?". She was turbine driven, engines by builder, and had a service speed of 15.5 knots. 662.75'L x 86.92'B. One pump room with 3 main pumps and a stripping system, Butterworth Tank Cleaning. Even in the "Tanker Register" the details are a bit sparse. Still, at least all the crew got off even if the ecological damage was high.
