Summary
Young Lady dragged anchor in heavy weather in Tees Bay. A windlass hydraulic motor failure occurred while weighing anchor, and the anchor subsequently snagged and damaged the CATS gas pipeline. The investigation identified an inappropriate anchoring decision and incomplete assessment of vessel–pipeline risks; recommendations addressed information, notification and pipeline protection.
