Case study
How the ScanFish ROTV solution can increase data coverage and efficiency of data acquisition during waste water monitoring surveys
The City of San Diego looked to the ScanFish Rocio model in EIVA’s ScanFish ROTV product line as a means of increasing data coverage and quality while at the same time decreasing vessel time.

Adaptable operation pattern
ScanFish Rocio's pattern in the water column is easily adjusted to ensure well-founded results of the survey task at hand.

Adaptable operation pattern
The ROTV has three operation modes and an intelligent anti-collision feature
Its pattern is therefore easily adjusted to ensure well-founded results of the survey task at hand.
The undulation operation mode allows for profiling of the water column in a V-curved path at a steady velocity and thus even data acquisition.

Undulation mode of the ScanFish Rocio ROTV
Adding to this the possibility of enabling either terrain-following or fixed depth mode, you are in complete control of the position of the vehicle and can at all times adjust it to fit your needs.

The ScanFish Rocio ROTV can be set to automatically follow the seabed in the ScanFish Flight software

It is also possible to set the ScanFish ROTV to operate at a fixed height from the seabed via the ScanFish Flight software

Controlling the ROTV's movements in ScanFish III Flight software
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.

ScanFish III Flight in action
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 Rocio models.
Robust product with a long service life
The practical design of the ScanFish models makes them so robust that they can be deployed in rough weather.

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.

Avoid obstacles more smoothly than ever
This autopilot flight mode uses your vessel’s echo sounder data as an early warning system to avoid obstacles while keeping sensors stable.

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.

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.

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 Pro, EIVA’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
