    Innovatum acquires new ROV

    Vessel & ROV News // June 12, 2013

    Innovatum, which carries out tracking and survey of submarine pipelines and cables, has added to its fleet of ROVs with a new Saab Seaeye Cougar XT.

    “Adding a Cougar XT Compact,” says managing director Terry Slater, “will bring more power to survey work when operating close inshore in the strong currents and tidal flows of the southern North Sea – without a significant increase in size of vehicle.”

    Designed especially for working in shallow waters and in tight situations, the low-profile Cougar XT Compact minimises the effect of current with its reduced frame size, buoyancy and weight – and a thinner 17mm tether cable that reduces the effect of drag. Its power to hold steady in cross currents and work with precise manoeuvrability comes from six highly responsive and power efficient thrusters, along with a fast acting control system.

    Despite its small size, the Cougar XT Compact can be fitted with a wide range of equipment. The Innovatum model is fitted with its own Smartrak system along with a high-resolution imaging sonar and dual-headed scanning profiler for mean seabed level measurement.

    Innovatum’s Smartrak 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 with ranges and accuracy said to be better than any other system.

    For survey work the Cougar, like the Falcon, 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 windfarms, interconnector power cables and coastal communications cables.
