1. NOTICE IS HEREBY GIVEN by the King’s Harbour Master Portsmouth that an Autonomous Surface Vessel (ASV) Sea Trial will be conducted in the Solent Areas during the period 18 to 20 January 2023.
2. ASV operations will be conducted in daylight only with a safety vessel in attendance throughout. The PAC 24 ‘16011’ is a 9-metre black and grey RHIB. and has a top speed of 40 knots. ‘16011’ will be accompanied by ‘Valkyrie 6’, which will accompany the craft from/to Round Tower Complex (Fountain Lake Jetty 5) to the operating areas and will act as the safety vessel for the trials. The staff operators embarked in ‘Valkyrie 6’ will intervene in the event of any safety issues as will the onboard coxswain. For the trial serials, ‘16011’ will be remotely/autonomously controlled, but crewed throughout, with the operators able to regain control quickly should circumstances require this. Speeds used for trials will vary but will remain within the 10-knot speed limit when within 1000 yards of the mean low water springs line.
