Naval Operations in the Eastern Solent 14-17 December 2015 (UK)

December 11th, 2015. NOTICE IS HEREBY GIVEN by the Queen’s Harbour Master Portsmouth that from Monday 14 December to Thursday 17 December 2015 a naval operation involving HMS QUORN will be taking place in the Eastern Solent from Ryde Middle to the area of the Forts. The majority of operations will be centred on “C” Anchorage, and will be limited to 12 hours per day. The ship will anchor at Spithead overnight.

  1. The majority of the operations will be “route surveying”, which will involve mapping of the seabed by sonar, followed by investigations of any unusual contacts that may be discovered. These operations will involve the ship operating at very slow speed. Investigations of contacts will involve use of remote controlled underwater vehicles and potentially divers. The ship will display Restricted in Ability to Manoeuvre lights/shapes when engaged in investigation operations (ball-diamond-ball in a vertical line or red-white-red all-round lights) in addition to normal lights for a vessel underway.
  2. HMS QUORN will coordinate its operations carefully with VTS Southampton and with QHM to ensure that investigation operations are deconflicted from major shipping movements in the area. Other shipping is to remain as far clear as practical when HMS QUORN is exhibiting lights/shapes as indicated in para 2 above, and are to call the ship before closing within one mile. HMS QUORN will maintain a listening watch on VHF Ch 11 and 12 throughout.
  3. For the duration of this operation, the temporary Exclusion Zone authorised in GD 2/13 is activated with a minimum approach distance of 100 metres in force based on HMS QUORN.
  4. For the duration of the operation QHM Harbour Control will be kept informed of the area of operations and may be contacted on VHF Ch 11 or by telephoning 02392 723689 for the latest information.
  5. Cancel this LNTM on Friday 18 December 2015.
