Klein picks Cambridge Pixel for offshore wind farm tracking
March 24, 2020
New Hampshire sensor technology provider Klein Marine Systems has selected radar and tracking technology from UK firm Cambridge Pixel to protect a Korean offshore wind farm.
The technology is integrated with radar, daylight and thermal cameras, AIS receiver, and a long-range acoustic device (LRAD) as part of Klein's HarborGuard maritime security and surveillance system. Cambridge Pixel enhanced its RadarWatch coastal surveillance software to support a long-range acoustic hailing and strobe searchlight device for the project.
Cambridge Pixel develops radar display, tracking and recording sub-systems. It supplied its RadarWatch coastal surveillance software, target tracking and radar recording technology to Klein Marine Systems, a subsidiary of Mitcham Industries, as part of a project to protect an offshore wind farm and its associated submarine transmission line off the coast of South Korea.
The radar display, tracking and recording technology has been integrated with the radar, daylight and thermal cameras, an AIS receiver and LRAD. The local integrator is Seoul-based iSenteck. The surveillance system monitors vessel traffic around the wind farm and along a 10km submarine transmission line carrying power from an offshore platform transmission station to the onshore distribution facility.
"We needed a modern, multi-window display that fuses information from radar sensors, transponders and cameras to present a consolidated view of vessel movement in the monitored area to our shore-based operators,” said Frank Cobis, vice president of Klein Marine Systems. “Cambridge Pixel's RadarWatch radar display application, target tracking software and real-time data recorder provided all the functionality and the flexibility we required for this programme.”
For the Korean wind farm project, an offshore platform hosting a Simrad Argus X-band radar, dual thermal and daylight camera from Moog Mercury and an AIS receiver was supported by Cambridge Pixel's SPx tracking server, which generates radar tracks corresponding to vessel movement in the monitored area. These track reports, along with camera video and AIS reports, are transmitted to the shore-based facility where the RadarWatch surveillance application presents the combined radar, camera and AIS transponder data in a unified operator-friendly display.
"We have worked with Cambridge Pixel for many years and have been impressed by their engineers' sensor expertise and their technical support to us and our integration partners,” said Cobis. “Also, the company was willing to customise the RadarWatch software to support a long-range acoustic and searchlight device. This allows the operator to audibly alert approaching vessels using either a microphone or a set of pre-recorded audio sounds."
RadarWatch is designed for coastal surveillance, small port and harbour security applications. It can display tiled maps, S57 and S63 electronic charts, video from up to four radars and 16 cameras, within multiple windows and across multiple screens. It is compatible with a wide range of radar scanners, including those from Kelvin Hughes, Simrad, Terma and Furuno, and provides a common software architecture that can be scaled to single or multi-sensor installations.
"We are delighted to be providing our RadarWatch display software, tracking and recording technology for this strategic coastal surveillance site,” said Andrew Haylett, principal engineer at Cambridge Pixel. “Our software's comprehensive support for generating alarms for vessels moving into a defined area around the protected zone was another key feature for Klein as it facilitates automatic steering of the camera towards the detected target and the ability to sound an audible alarm or signal using the strobe searchlight."
The RadarWatch software accepts open data formats such as Asterix and NMEA-0183 and works with other Cambridge Pixel software applications, including SPx Fusion, SPx Camera Manager and SPx Radar Data Recorder. Augmented vision is also implemented within RadarWatch to fuse primary radar tracks with data from ship (AIS) and, where appropriate, aircraft (ADS-B and IFF) transponders and then display this as an overlay to camera video.
Cambridge Pixel's radar technology is used in naval, air traffic control, vessel traffic, commercial shipping, security, surveillance and airborne radar applications. Its systems have been implemented in mission-critical applications with companies such as BAE Systems, Frontier Electronic Systems, Blighter Surveillance Systems, Exelis, Hanwha Systems, Kelvin Hughes, Lockheed Martin, Navtech Radar, Raytheon, Saab Sensis, Royal Thai Air Force, Sofresud and Tellumat.
Klein Marine Systems has over fifty years of experience in the development and manufacture of sonar products including side scan and bathymetry systems and maritime surveillance and security systems.
