Why Fetch is perfect for your operations

Think of Fetch as your underwater data hub. We work with you to integrate your chosen sensors, creating a reliable gateway to your subsea data that you can access remotely whenever needed.

Your advanced seabed geodesy projects demand precision and reliability. We’ve developed Fetch to deliver both, through seamless integration with our Ranger 2 system for efficient data collection.

We understand your commitment to reducing operational costs and environmental impact. Fetch helps you achieve both through long-term deployment capabilities and remote data harvesting, minimising vessel time and emissions.

Fetch your subsea data

Fetch is a long-life subsea sensor logging node with a battery life option of up to 10 years that enables data to be wirelessly extracted via its integrated high speed acoustic modem. We’ve designed every aspect of Fetch to support your underwater monitoring needs, from its high-capacity battery packs to its compatibility with our Ultra-Short BaseLine (USBL) positioning systems. Our team brings decades of experience in subsea technology to help you achieve reliable, long-term monitoring success.

An innovative free-fall deployment system ensures your Fetch lands upright every time, saving you valuable vessel time and cost.

Your Fetch can be configured with an array of different sensors to suit your monitoring applications. Standard sensors include high accuracy pressure, temperature and sound velocity as well as inclination. Other sensors can be integrated internally or externally as required.

Smart power management means the subsea sensor logging nodes only activate when needed, maximising battery life. Data captured by the active nodes is time-stamped and stored on an SD memory card ready for retrieval,

You can configure your sampling regime before deployment and update it in-situ via the acoustic modem which is also used to recover the data to the surface. The 9,000 bits per second modem transfer rate enables data to be extracted in minimal vessel time so reducing your operational costs.

When you’re ready to retrieve your Fetch, a simple acoustic command brings it safely to the surface under its own buoyancy ready for collection.

Why Fetch AZA is perfect for your operations

Your Fetch AZA system offers a comprehensive solution transforming your ocean monitoring operations across multiple applications, including environmental surveys, seabed deformation monitoring, and low-cost in-situ ocean surveillance. Unlike traditional pressure sensors, which suffer from drift over time, the Fetch AZA technology autonomously recalibrates in-situ.

A unique control system periodically cycles the pressure sensor from ambient seabed pressure to near-zero, enabling comparison to a highly accurate low-pressure reference sensor for calibration. The reference sensor is never subjected to ambient pressure and is accurate to changes of less than a millibar, or about 1cm of head of water.

The sensors are low power, allowing for long endurance deployments, and provide time-stamped data, which is often critical to your commercial or scientific objectives. With their in-built data storage and high-speed modem capacity, they can support your data collection and harvesting using a wide range of other Sonardyne and third-party sensors (High precision temperature and sound velocity as well as inclination) and are compatible with any Sonardyne 6G equipment, including Ultra-Short BaseLine (USBL) systems and modems.

For science

These capabilities have created an instrument that revolutionises seabed measurements, across ocean science and the commercial sectors. Scientists can now undertake measurements, critical to understanding tectonic processes, at a resolution they’ve never been able to achieve before.

For business

In the commercial sphere, Fetch AZA meets upstream production companies’ long-term goals of measuring 1 cm/year of vertical movement across their energy fields. These fine-scale measurements provide a powerful tool for proactive reservoir management throughout their lifecycle. This is a key enabler for maximising economic recovery.

Its remote capabilities represent a significant operational advantage, as data can be retrieved using Uncrewed Surface Vessels (USVs) from over-the-horizon locations, eliminating the need for expensive crewed vessels and reducing your costs, personnel risks and environmental impact.

This combination of remote operation, sustained accuracy, and precise repeatability makes the Fetch AZA an ideal choice if you are seeking a reliable, cost-effective ocean monitoring solution.

Make time-critical decisions with near real-time data delivery

Analyse the structure of your velocity and backscatter intensity data in far finer detail than previously possible with our proprietary formats delivering up to ten times greater spatial resolution. Origin 600 delivers conventional PD0 data as standard, whilst logging the higher resolution data to further enhance your results. All data is recorded to the onboard storage unit with 1 TB capacity.

Reduce your risks and device retrieval costs with power-efficient electronics and a rechargeable internal battery which allows deployments of up to three months on a single charge. A dual battery option allows you to operate longer or more energy demanding deployments. External power can be supplied by PoE, allowing you to program and download data without a separate power supply.

Monitor waves, mean currents and turbulence using Origin 600’s five-beam configuration and sampling frequency of up to 4 Hz on all beams. Your Origin’s built-in acoustic modem enables you to remotely access the unit while it’s deployed using an accompanying topside modem (sold separately) and the Origin Topside PC software. This allows you to check battery and storage, inspect and upload data, reconfigure schedules and run quality control, all whilst your ADCP is on the seabed.

Add external sensors to your ADCP mounting frame, and fuse with your Origin data via the Edge processing software, to really get the most out of every single deployment. You can upload sensor apps via Origin Portal or Topside and the resulting data will be exported over the acoustic modem.

What is Edge?

Discover the key to your customised ADCP data…

A suite of intuitive software tools and the Sonardyne Edge computing environment allows you to get the most out of your Origin 600. The Origin Portal web UI lets you configure your ADCP in operational conditions, including modification of the sampling schedule. Reduce your operational risks by setting your schedules before deployment using the Origin Scheduler PC application. Two schedules can be run together, allowing dual monitoring tasks to be performed with a single device. File data can be inspected using the Origin Viewer software package.

Origin 600 is compatible with your standard mounting infrastructure, reducing your risk and cost for upgrading to this device. For a complete solution, we can provide a dedicated, rugged stand with space for dual redundant releases.

An innovative, robust acoustic design

Its pioneering satellite-dish design allows Origin 65 to match or exceed the acoustic performance of competing instruments. All while reducing your costs, prolonging battery life and increasing robustness to pressure cycling – a long-standing problem with low-frequency ADCPs.

Connect to the subsea world – integrated modem and PIES

Check or reprogramme your Origin 65 acoustically while on the seabed via its integrated acoustic modem. There’s no need to retrieve the device or interrupt your operation.

During your operations, Pressure Inverted Echosounder (PIES) measurements are interleaved with current profiles. This allows time-of-flight (TOF) and average sound velocity (SV) to be determined in-situ alongside the ADCP sampling and the data fused in PD0, delivering all data time-aligned in one place.

At the end of a deployment, the modem can be used to trigger the integrated acoustic release, allowing the device to float to the surface for retrieval.

Don't just settle for standard – introducing A-gram and B-gram data

Your Origin 65 delivers industry standard PD0 data format as default, but why settle for standard when you can have up to ten times greater resolution?

Origin generates our exclusive A-gram and B-gram formats. These offer up to ten times greater spatial resolution than PD0 and expose raw acoustic data which you can them interrogate for your specific operations.

Origin ADCP – Edge enabled

Edge lets you run data processing apps on Origin 65 which are customised to your exact needs. The system will produce the information you are most interested in, rather than bulky raw data that would normally be processed once the device is recovered. You can harvest this data as a file or as a live stream, either through a cabled connection or Origin 65’s integrated acoustic modem.

What is Edge? Discover the key to your customised ADCP data…

Edge computing gives you the ability to write your own apps for Origin via our Software Development Kit (Edge SDK) so that you can focus on the data you need from your operation. To get you started, some of the apps already available to download include simple background currents and quality metrics.

Data gathered by your Origin can also be processed to your requirements within Edge before it is harvested. This minimises both the amount of unnecessary data in each upload and the time taken for each harvest.

Origin rewrites the story of your relationship with an ADCP

Our Origin family of ADCPs represent the latest in cutting edge underwater profiling technology. Able to analyse mean currents, waves and turbulence, and integrate with external sensors to provide pH levels, temperature and other data, Origin delivers comprehensive, reliable and timely data sets for your underwater operations.

With on-board Edge data processing and built-in acoustic modems, Origin can also process and deliver your data in almost real-time. This data is delivered in conventional PD0 format as standard but can be programmed to present results in our exclusive A-gram and B-gram formats, giving you up to 10 x greater spatial resolution detail.

Available in two models, Origin 65 for deep water profiling and Origin 600 for near and inshore waters, there is an Origin ADCP to suit your operation.

Why should you invest?

Origin ADCP family gives you the data you need, at a level of detail not available anywhere else on the market. Their ability to integrate with third party sensors unlocks additional capability and protects your investment.

Rechargeable batteries in Origin 600 give you rapid redeployment times as the unit can be recharged on the back deck whilst data is being downloaded before it’s returned to the seabed. Depending on your programme requirements, Origin 65 can operate for up to two years on the seabed before needing to replace its batteries.

Whichever size suits you best, they are both compatible with our Ranger 2 USBL equipment so you can harvest data and update your operation schedules mid-mission.

Go deeper, last longer and lift more with our family of RT 6 acoustic releases

Our RT 6s come in three popular depth ratings, 1,000 m, 3,000 m and 6,000 m as well as an HD model capable of operating at up to 7,000 m with loads of up to 2500kg. There’s a model to suit any of your offshore operations.

All of our RT 6 models are compatible with our Ranger 2 USBL. You can locate, operate and recover the releases quickly and simply with this globally used system, saving you time and the complexity of operating several systems at once.

Spend less time recovering and more time collecting data with up to 2.5 years battery life. We understand that your time is precious, so our RT 6 releases feature a minimum of 13 months battery life, depending on the model, meaning you spend less time recovering equipment and your assets spend more time in operation.

Overview

Acoustic release transponders are a vital piece of ocean equipment – relied upon by energy, defence and science users to moor valuable equipment strings for years at a time, and when commanded to do so, reliably return equipment and logged data to the surface.

Transponders need to be tough, reliable and easy to work with. RT 6-6000 meets these requirements.

Part of our new range of acoustic releases, RT 6-6000 combines the extensive mechanical design track record of our renowned ORTs and DORTs with the flexibility of our 6G platform, resulting in enhanced battery life and perhaps most significantly, compatibility with our Ranger 2 USBL family

With RT 6-6000, you can use your vessel’s Ranger 2 USBL to deploy, track, locate and command the instrument – removing the need for a separate topside unit. If you don’t have access to a Ranger 2 USBL, our rugged and lightweight Deck Topside with an over-the-side dunker is all you need to both configure and command RT 6-6000s.
