Navigate with confidence using Vigilant Forward Looking Sonar
How do you ensure your research or survey vessel can safely navigate the marine environment? What’s the best way to avoid hidden obstacles ahead, which interrupt your surveys or increase potential grounding risks? Charts can only provide you with so much information.
The Vigilant family delivers the best forward looking sonar (FLS) capability on the market with a range of up to 1500m and depth of up to 100m. Give your crew time to react with the highest resolution 3D imagery available, providing unrivalled mapping of the water column and sea bed. Use automated alerts to highlight hidden threats. Vigilant is a proven, world-leading sonar system that is reliable and easy to use. With an operational speed of up to 25kn, you’ll have the confidence to navigate safely wherever your chosen passage takes you.
Make your survey missions count
Survey missions are costly and time-consuming operations for companies working offshore. But vitally important. Maximising the efficiency of your exploration is essential before you set out.
Solstice’s small and compact arrays are optimised for low-logistical AUVs and towed bodies, with wide survey swaths, to ensure that each pass is as efficient as possible.
The Solstice arrays consume only 18W of power, making the most of the AUVs endurance capability or the towed body’s power capacity and payload limits. Delivering a 200m wide swath ensures high coverage rates, increasing your site characterisation efficiency without compromising on details.
Eliminate image distortion and noise interference
Unlike most conventional side-scan sonars, Solstice delivers multiple apertures to improve the signal-to-noise ration performance. With a unique back-projection beam-forming technique, developed by Wavefront Systems, it focuses on every single pixel in the image.
Solstice also uses knowledge of the platform motion to eliminate effects of roll, pitch and yaw to produce undistorted imagery with 100% ground coverage. With the arrays being interferometric, pixels are co-located to ensure you receive clear position-based imagery.
Designed to produce high contrast imagery, even in shallow and littoral waters, Solstice eliminates noise from multi-path reverberation, enhancing contrast in the imagery you see.
Giving you an early warning of integrity breaches
It’s not always easy to pinpoint when and where small hydrocarbon leaks have started. Early detection is vital to save expensive problems further down the line.
Sentry is an active sonar that projects a short duration high-bandwidth pulse into the water. It listens for echoes from any objects such as structures, ROVs or hydrocarbon leaks. The position is automatically displayed and transmitted to your remote monitoring station. Your fully automatic system will raise the alarm if any hydrocarbon leak is detected.
Sentry can detect leaks of monophase gas, down to 0.1 litres per minute (the equivalent of 1 barrel of oil per day) or monophase oil to 1 litre per minute (equivalent to 10 barrels of oil per day).
Use Sentry to automatically monitor small amounts of hydrocarbon leaks and send you the position so you can react straight away.
Integrated sonar solutions for more significant subsea assets
Solstice provides you with the perfect solution. Our compact, high-performance Solstice side-scan sonar contains powerful automatic target recognition (ATR) algorithms for inspection of greater lengths of subsea assets, such as trunk pipelines. They can be integrated into an AUV to detect any containment losses of oil or gas.
Containment failure at an offshore carbon capture and storage site, whilst viewed as highly unlikely, is of significant concern to regulatory bodies, operators and environmental groups. Using our Sentry sonar, combined with Sonardyne’s chemical sensing lander, you’ll receive sensitive and reliable automated leak detection across vast areas.
The Vigilant family delivers the best forward looking sonar (FLS) capability on the market with a range of up to 1500m and depth of up to 100m. Give your crew time to react with the highest resolution 3D imagery available with unrivalled mapping of the water column and sea bed. Use automated alerts to highlight hidden threats. It’s a proven, world-leading sonar system that is reliable and easy to use. With an operational speed of up to 25kn, Vigilant gives you the confidence to navigate safely, wherever your customers choose to take their adventures. Its like having a parking sensor on the front of the vessel.
Sentinel Side-Scan Sonar allows you to capture stunning imagery at longer ranges, with interferometric capability providing co-located 3D data. The low power multibeam design makes Solstice the number one side-scan sonar solution for AUV’s and towed bodies. The design allows for high-contrast imagery, even in shallow water, littoral waters eliminating noise from multi-path reverberation, enhancing the contrast of the imagery. The result is improved probability of detection and decreased probability of false alarms, improving the efficiency of your mission.
Why Should You Choose Our Sonar Solutions?
- Vigilant transforms your underwater situational awareness with its unique range of up to 1500m capability.
- Highly detailed 3D Sonar images allow for safe navigation of the seabed and collision avoidance.
- Long-range hazard detection using Vigilant’s smart software clearly indicates potential problems. By overlaying onto your charts, your crew have the best information at their fingertips.
- The compact design fits easily within the vessel with multiple mounting options tailored to your individual craft.
- Solstice has been designed to produce high-contrast imagery, even in shallow, littoral waters. Eliminating noise from multi-path reverberation enhances the contrast of the imagery.
- It employs unique array technology, allowing wide swath coverage generally associated with wide vertical beamwidth.
- Solstice provides the shadow contrast associated with very narrow vertical beams.
- Solstice’s 300 m-rated, 682 mm long, 2.11 kg arrays have 32 multibeam elements. This configuration ensures that your AUV or towed body can gather more data with higher image fidelity.
- Sentry automatically warns of integrity breaches around subsea oil and gas assets with 1 billion cubic feet of seawater monitoring capability.
- Delivering 360° of coverage.
- Either mounted on an integrated landed or standalone battery operated for remote operation, Sentry provides a solution for hydrocarbon integrity monitoring.
