Product no :: 0100108-R

Intelligent wide-sweep ROTV for magnetometer surveys

The ScanFish Katria 3D is an intelligent wide-sweep remotely operated towed vehicle (ROTV) solution for time-efficient magnetometer surveys.

This model is ready to be connected with high-sensitivity magnetometers for maximum target detection efficiency. This makes it an effective tool for detection of sub-bottom magnetic anomalies. It is also possible to rent the ScanFish Katria 3D with magnetometers

Enhancing the manoeuvrability and flight path capabilities of ScanFish

ScanFish Katria 3D is a hardware solution that augments the navigational capabilities of EIVA's range of ScanFish remotely operated towed vehicles (ROTVs) by introducing horizontal movement control capabilities.

This enhancement – enabled through the addition of four carefully engineered side-mounted flaps – delivers ScanFish operators the freedom to navigate the vehicle horizontally through the water column, in addition to the vertical pathing capability of a base model ScanFish.

Deployment of the ScanFish Katria ROTV
Wide and dense coverage at a fixed height
The terrain-following operation mode of the intelligent ROTV ensures that it maintains a fixed height as close to the seabed as possible, depending on the topography. This equals high-quality data.
The horizontal array of underwater magnetometers enables you to cover a larger survey area in less time and ensures dense coverage, translating into better indication of signal strength and origin in one sweep.

The ScanFish Katria ROTV can be set to automatically follow the seabed in the ScanFish Flight software.
Optional extras
The ScanFish Katria standard package combined with the optional extras constitute a turn-key solution.

Optional extras of the ScanFish Katria package
This ScanFish Katria package combined with your own magnetometers and a number of optional extras constitute a turn-key solution
From topside unit and subsea cable termination to handling system and the possibility of mounting a pinger/beacon, Ultra-short Baseline (USBL) positioning system, or video and light, we offer you all the necessary components for an optimal magnetometer survey solution that matches your exact needs.
Want to upgrade your ScanFish setup with EIVA software?
NaviSuite 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 (including G-882 magnetometers) 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.

Optional extras
3D steering
Hardware solution which introduces horizontal movement control capabilities

Geometrics MagLogTM recording software
Data acquisition and real-time monitoring

ROTV cradle
For deck mounting, incl tarpaulin

EIVA OceanEnviro^TM winch system
PC

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.
