Smart Video & Sensing gains SIL2 accreditation for bridge remote control operation

UK supplier of sensing and detection solutions to the transport industry, Smart Video & Sensing, has achieved a Safety Integrity Level (SIL) rating of SIL2 on a recent project to bring remote control operation to Sandfield swing bridge over the Gloucester & Sharpness canal.

The Sandfield Bridge operates on average 4,500 times during the seven-month season but at busy weekends during the holiday period can operate up to 80 times in a day. The objective of the project undertaken on behalf of Kier Integrated Services for the Canal & River Trust was to convert the bridge to remote control operation.

The system design incorporated traffic signals, barriers, laser scanners, CCTV, intercom, VoIP, help points and the development of an app from a boater’s smart device to local wi-fi to automatically trigger the opening of the bridge. Barriers and traffic signals on either end of the bridge control vehicular and pedestrian traffic and light signals on the bridge approaches control approaching waterway traffic.

The SIL assessment was undertaken by DNV-GL, a global accredited management certification organisation, on behalf of SVS.
