ScanFish TropheusHigh-speed ROTV for UXO operations
The ScanFish Tropheus is an ROTV especially designed for UXO detection. It functions as depressor of any side-scan sonar and is the optimum solution in terms of quality, efficiency and safety.
Continuous acquisition of accurate and comprehensive data The intelligent control of the ScanFish Tropheus ensures that the ROTV together with the side-scan sonar mounted on the underside maintain a constant, fixed altitude in proportion to the seabed – and far closer than solutions without a depressor.
Add to this a high tow speed of up to 10 knots and the fact that the ScanFish Tropheus allows for continuous data acquisition, you are ensured more accurate and comprehensive data and thus extensively detailed images of any potential UXO targets.
Avoid risking your crew’s safety The ScanFish Tropheus can be towed by an unmanned vessel. Consequently, you avoid having to pose the crew to any risks during the operation. All you need to do is define the altitude of the ScanFish Tropheus, and its motion, pressure and altitude sensors will do the rest of the job, ensuring high stability of the vehicle and sonar in the water.
Looking for a total solution?ScanFish Tropheus is available with all the standard components and optional extras that are required to constitute a turn-key UXO solution. From topside unit to subsea cable termination and multi-ping side-scan sonar, we offer you all the necessary components for an affordable UXO detection solution that will make a great difference to the safety and efficiency of future operations.
Detailed and safe mapping of potential UXO areasEliminate data uncertainty with high-quality seabed imaging
User-friendly control and monitoring software solutionThe ScanFish Tropheus comes with the ScanFish III Flight software, which is an easy-to-use software system allowing for control and monitoring of the ROTV.
Intuitive interface for an advanced vehicleOnly a minimum of training is required to prepare the crew to operate the ROTV, which means you will be ready to set sail within a short period of time. Moreover, there is no risk of wasting time on difficulties resulting from complicated software user interface.
Via the intuitive interface of ScanFish III Flight, you are in complete control of the position of the ROTV by defining its height compared to the seabed. At the same time, you can monitor its position in the water, and an alarm menu will warn you of any irregularities.
On-site calibration A pre-flight feature allows for test and calibration of the ScanFish Tropheus on-site prior to deployment, promising you the highest possible performance and data quality.
Recording of flight dataAcquired data can be analysed by means of a flight recording feature. It enables you to play back all flights and for example quickly locate the cause of any irregularities, thus enhancing the quality of your results and saving survey time.
Real-time data monitoring and target classificationThe EIVA NaviScan software is available as an optional extra, enabling data acquisition and real-time monitoring through high-quality displays. This, together with the possibility of target selection and classification, will increase the success rate of your UXO operations.
Affordable solution with many benefitsDespite the many benefits offered by the ScanFish Tropheus, it comes at only a small extra cost compared to a towed sonar and a very competitive price in comparison with AUV solutions.
Effective terrain-following operation modeThe terrain-following operation mode of the ScanFish Tropheus ensures optimal positioning of the side-scan sonar in the water.
About ScanFish TropheusScanFish Tropheus is third generation of the ScanFish ROTV family, a proven solution that has always made the grade in terms of efficiency and durability. In further developing this product range, we are able to offer you an enhanced product of the highest quality.
Robust product with a long service lifeQuality materials and easily replaced wear parts characterise the ScanFish Tropheus and contribute to a high ROI through a long service life.
The practical design of the ScanFish Tropheus makes it so robust that it can be deployed in rough weather. This saves time as the risk of downtime is vastly reduced. Two side plates with bars, which also function as handles, protect the body and facilitate handling, thus reducing the risks posed to the ROTV in the water and ensuring the safety of the crew during deployment and recovery.
Easily stored on deckThe ScanFish Tropheus comes with a storage cradle for permanent storage of the ROTV and side-scan sonar on deck, taking up a minimum of space. The cradle protects the system and ensures that it always can be deployed quickly as it is right at hand.
