Applications

Offshore / Marine Energy

Underwater robotics and instrumentation have been used for long time in the offshore and Oil&Gas sectors, offering cost saving and efficient solutions where safety and operational limits are at stake.

Subsea Tech assists the sector operators by offering a range of standard and bespoke robotized solutions for operation monitoring and maintenance support of underwater offshore infrastructures.

Offshore infrastructure inspection

Subsea tech's mini-ROVs have been used for several years by the main stakeholders in the offshore and Oil&Gas sectors to make the daily work of maintenance teams easier. Subsea Tech's mini-ROVs compactness and lightness offer maximum deployment flexibility from any place (platform, vessel, etc.). On top of there advanced inspection capacities (2 high resolution video cameras, one being mounted on pan&tilt), Subsea Tech's mini-ROVs can easily embed an imaging sonar (acoustic camera) to carry out operations in very low visbility conditions. Many other accessories can be integrated on Subsea Tech's mini-ROVs to enhance the operator's experience : acoustic positioning (USBL), manipulator, cutter, mechanical sonar, etc.

FPSO inspection

As for offshore infrastructures, FPSO (Floating Production Storage and Offloading) working environment is favourable to the use of heavy underwater inspection and work systems such as work class ROV. However, some operations such as hull or thrusters inspection shall require quick deployment of smaller devices to avoid damaging the structures. Subsea Tech's mini-ROVs are especially designed for such occasional inspections. Thanks to their small dimensions, the operator can inspect areas that cannot be reached with bigger ROVs. Furthermore, NDT tools such as Cygnus US gauges or Buckleys CP probes can easily be integrated on Subsea Tech's mini-ROV. Preliminar UWILD operations also allows optimizing FPSO maintenance scheduling and budget.
