THV Alert

 

Trinity House’s Rapid Intervention Vessel (RIV), ALERT, delivered in 2006, has been designed with buoy handling, wreck marking, towing and multibeam and side scan hydrographic surveying capability.

At 39.3 metres long, she is fitted with a range of high specification survey equipment and to the highest and most modern technical standards. With DP1 dynamic positioning, a service speed of 15 knots and a maximum speed of 17 knots, ALERT will be deployed primarily to cover the southeast coast where she will be able to respond rapidly to any maritime incident.
