Cougar XT Compact, fitted with Innovatum’s Smartrak system, brings power to inshore survey work in strong currents and tidal flows.

Demand from the offshore wind industry has led Innovatum to add a second Saab Seaeye Cougar XT Compact to its ROV fleet.

This comes as Innovatum’s reputation grows in the offshore wind industry for cutting the cost of inshore survey work.

They have achieved this by creating the world’s smallest system of compact and rapidly mobilised packages for the location, tracking and survey of inshore and coastal pipelines and cables. For survey work close inshore in the strong currents and tidal flows of the southern North Sea, the Cougar’s six-strong thruster power is essential, says Innovatum’s managing director Terry Slater.

Designed especially for working in shallow waters and in tight situations, the low-profile Cougar XT Compact version minimises the effect of current with its reduced frame size, buoyancy and weightand a thinner 17mm tether cable that reduces  the effect of drag.

Innovatum’s Smartrak is the only system in the world that can sense cables carrying either AC or DC current; and cables carrying no current or signal at all. It can also undertake passive tracking of steel pipelines.

For survey work the Cougar has the advantage of a low electrical and acoustic noise signature for optimum survey sensor data.

The Innovatum system creates comprehensive reports and charts showing accurate cable route and depth of burial along the route. This data is required by installation contractors, owners and regulatory authorities, to ensure that the cable is properly buried and not in danger of being exposed to damage.

The system can undertake submarine cable surveys in shallow water depths – the typical scenario for offshore wind farms – interconnector power cables and coastal communications cables.

Innovatum is the world’s leading manufacturer of magnetic sensors for the location, tracking and survey of submarine pipelines and cables. It has over thirty years continuous development experience in the field and its systems are sold world-wide.

Saab Seaeye is the world’s largest manufacturer of electric ROVs, and now  includes Saab’s underwater vehicle range of tethered, autonomous and hybrid  underwater vehicle systems for the defence industry.
