Multi-purpose, high payload capacity ROTV for oceanographic surveys

ScanFish XL is the largest and latest addition to EIVA’s family of ScanFish remotely operated towed vehicles (ROTVs). Designed to host a payload of up to 400 kg, ScanFish XL offers freedom from sensor and instrumentation limitations of a typical ROTV, enabling comprehensive multi-instrument data collection with every runline.

By design, ScanFish XL is capable of what we refer to as 3D steering – meaning that it is able to navigate both vertically and horizontally through the water column, for greater flexibility in executing runlines.

ScanFish XL is built for an operational speed of up to 6 knots, but with inherently very low roll and pitch, the high stability of ScanFish XL makes it an ideal platform for payloads sensitive to unwanted movements.

Altogether, ScanFish XL delivers superior performance on subsea survey operations compared to work class ROV solutions, across key metrics including speed, cost and payload capacity.

As an optional extra, NaviPac Pro can provide autopilot guidance, enabling the ROTV to follow a predefined runline as instructed by the software.

    Advanced navigation possibilities

    By design, ScanFish XL is capable of what we refer to as 3D steering

    ScanFish XL is able to navigate both vertically and horizontally through the water column, for greater flexibility in executing dynamic runlines, when sideways currents influence the ROTV position, or long tow cables are used in deep water.

    The ROTV is built for an operational speed of up to 6 knots, but with inherently very low roll and pitch, the high stability of ScanFish XL makes it an ideal platform for payloads sensitive to unwanted movements.

    Altogether, ScanFish XL delivers superior performance on subsea survey operations compared to work class ROV solutions, across key metrics including speed, cost and payload capacity.

    Robust product with a long service life

    Quality materials and easily replaced wear parts characterise the ScanFish range and contribute to a high ROI through a long service life

    The practical design of the ScanFish models makes them so robust that they 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.

    Want to upgrade your ScanFish setup with EIVA NaviSuite software?

    Multi-featured survey software for data acquisition, navigation and/or processing

    With the software bundle NaviSuite Kuda Pro, access survey tools which allow you to perform advanced runline planning and positioning calculations (with the navigation solution NaviPac). You can easily interface a wide variety of sensors into NaviSuite for real-time data displays and QC, as well as perform data processing (with NaviEdit and/or NaviModel).

    Avoid obstacles more smoothly than ever

    With NaviSuite, you can also optimise operations with autopilot guidance such as Vessel-Aided Terrain Follow mode. This flight mode uses your vessel’s echo sounder data as an early warning system to avoid steep obstacles while keeping sensors stable.

    Only 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 a complicated software user interface.

    Via the intuitive interface of ScanFish 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 alert panel will warn you of any irregularities.

    On-site calibration

    A pre-flight feature allows for testing and calibration of the ScanFish ROTV on-site prior to deployment, promising you the highest possible performance and data quality.

    Recording of flight data

    Acquired ROTV 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.

    Automatic control of winch

    ScanFish Flight can be set up to control the winch towing the ScanFish ROTV, thereby ensuring an optimal cable length adjusted to the movements of the ROTV. This is especially relevant for the ScanFish Konia and ScanFish Rocio models.

    Vessel-Aided Terrain Follow mode

    Avoid obstacles more smoothly than ever through automated real-time calculations – this flight mode uses your vessel’s echo sounder data as an early warning system to avoid obstacles while keeping sensors stable.

    Controlling the ROTV's movements in ScanFish III Fligh software

    Video showing the ScanFish Vessel-Aided Terrain Follow mode in action, making the ScanFish avoid steep obstacles on the seabed more smoothly than it would have if it were using only the ScanFish altimeter sensor for obstacle avoidance – thereby achieving stability for optimal sensor performance 

    The ScanFish Vessel-Aided Terrain Follow mode optimises your vertical runlines based on a DTM (online and/or pre-surveyed). The main advantages are…

    It ensures smooth obstacle avoidance, so your data collection isn’t disturbed by any sudden movements of the ROTV, which could otherwise occur if there is a large, steep obstacle, such as a boulder. This is because the altimeter sensor onboard the ScanFish would register the obstacle when closer to it, causing the ScanFish to move quickly out of the way to avoid it. On the other hand, with the Vessel-Aided Terrain Follow mode, the ScanFish can react ahead of time thanks to an early warning from the DTM, and therefore you have the option to make it do avoid obstacles more smoothly over time.

    You minimise risks to your ROTV by not only reliably predicting obstacles and avoiding them (as the ScanFish ROTV already does) but also customising how you avoid them, so your ScanFish ROTV’s vertical steering is tailored to your specific ROTV configuration (with this new mode, you can customise the area in which obstacles are avoided and the slope with which the ROTV avoids them.

    ScanFish and NaviSuite software in action

    The area highlighted in yellow is the corridor in which objects are considered relevant obstacles to be avoided using the Vessel-Aided Terrain Follow mode – and the two yellow spheres below the ScanFish model show the correction to the vertical route

    Stay safe with a failsafe

    This new steering mode is doubly designed to avoid any harm to your ScanFish. The EIVA team has equipped it with a failsafe function for the unlikely case of a malfunction in the setup causing your ScanFish to receive erroneous data from the synthetic altimeter calculated by NaviPac. An error in the synthetic altimeter can occur for example if you are using a pre-surveyed DTM which is outdated, as a new obstacle has appeared since then. In such a case, the priority will always be given to the minimum height registered by the ROTV altimeter mounted on your ScanFish.

    Easy integration with your ScanFish ROTV

    This automated steering mode is available for all ScanFish systems. In addition to your vessel and any model of ScanFish ROTV, this steering mode uses the following components…

    • Multi-beam echo sounder on the vessel which is towing the ScanFish (optional as you can alternatively use pre-surveyed DTMs):
      • Acquires seabed data to create a real-time DTM
    • NaviSuite Kuda ProEIVA’s hydrographic survey software solution (alternatively, if using a pre-surveyed DTM, you can use NaviPac Pro or NaviPac Single User):
      • Collects multi-beam echo sounder data and creates a DTM in real time – or displays a historical DTM
      • Calculates your ROTV’s optimal vertical route based on the DTM and your settings for obstacle avoidance
      • Inputs synthetic altimeter values to your ScanFish Flight software so you follow this route
