Mr. Foulkes

To ask the Secretary of State for Defence what were the exact circumstances, including time and location, of the collision between the Drum and HMS Otus; what damage was sustained by both vessels; what injuries were sustained by anyone involved; what kind of inquiry he has instituted into the incident; and if he will make a statement.

Mr. Ian Stewart

At 02.45 on 16 July 1988 a collision occurred about 7 nautical miles south of the Mull of Kintyre light between the masts of the submarine, HMS Otus, and the yacht Drum. HMS Otus surfaced immediately after the collision. Drum's outer skin was punctured and she also suffered some damage to her guard rails and rigging, hut she was able to continue her passage without assistance. HMS Otus's masts were damaged. No one was injured in the collision. A formal naval board of inquiry is currently under way.

Mr. O'Neill

To ask the Secretary of State for Defence if the collision between HMS Otus and the yacht Drum occurred in lanes designated for naval use.

Mr. Ian Stewart

The collision occurred in a designated submarine exercise area which is marked as such on Admiralty charts.
