Enhancing the manoeuvrability and flight path capabilities of ScanFish

ScanFish 3D steering 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.

ScanFish 3D steering is available as a retrofit onto existing ScanFish series units.

    3D steering of EIVA ScanFish ROTVs

    Making a wide ROTV reach even wider

    The EIVA ScanFish remotely operated towed vehicle (ROTV) models can follow the seabed, keep a fixed depth, or undulate up and down through the water. With just a simple addition, though, they are able to take even another tack.

    EIVA has developed an easy and effective way to modify the existing ScanFish ROTV models with '3D' steering – that is, the ability to not only swim up and down, but sideways as well during subsea survey operations.

    Increase subsea survey efficiency with horizontal steering

    The optional 3D upgrade to the ScanFish ROTV allows the operator to control not just the vertical but also the horizontal movement of any ScanFish ROTV through the water, with a fast steering response and a wide range of lateral movement of +/- 25 metres.

    The improvement to ScanFish manoeuvrability brings numerous performance advantages. It is especially useful when operating in conditions where currents may influence ROTV positioning, when long tow cables are used in deep water, or when charting runlines that are not straight, to name but a few scenarios.

    It also increases survey efficiency, since overlap of sensor coverage can be reduced and the number of re-surveys required can be minimised. The upgrade is available on all ScanFish models, but is especially relevant to the ScanFish Katria model, in its terrain-following operation mode for wide-sweep UXO surveys.

    Moreover, 3D steering can be used with NaviPac Pro – the navigation and positioning product of EIVA NaviSuite – as an optional extra. The software's auto-pilot feature will allow for the ROTV to follow a predefined runline as instructed by the software.

    Already have a ScanFish ROTV? Then all you need is an upgrade

    As an upgrade, the 3D steering requires modifications to the ScanFish subsea controller housing (extra ports for the flaps), replacement of side-panels, and a software upgrade of both firmware and the ScanFish III Flight software.

    In other words, EIVA outfits the ScanFish model with an extra set of ‘fins’ to give it a greater range of movement, and then teaches it to use its new 3D steering ability.
