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

User-friendly control and monitoring software solution
All ScanFish models come with the ScanFish III Flight software, which is an easy-to-use software system allowing for control and monitoring of the ROTV.
User-friendly control and monitoring software solution
All ScanFish models come with the ScanFish III Flight software, which is an easy-to-use software system allowing for control and monitoring of the ROTV.
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 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 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 III 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.

Robust product with a long service life
The practical design of the ScanFish III 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 III range and contribute to a high ROI through a long service life
The practical design of the ScanFish III 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.
