An ingenious idea from Saab Seaeye customer, Stinger Technology, has found a way to penetrate the labyrinth inside offshore production tanks in search of environmental contaminates prior to decommissioning.

They managed to squeeze a unique underwater robotic systems configuration loaded with sampling technology through a 150 cm square hatch to search the tank’s internal maze of baffles, and navigate along 25.5 cm diameter pipe-runs of curves and bends.

Stinger’s idea turned the already compact Saab Seaeye Falcon into a ‘mother ship’ from which is launched an even smaller fly-out VideoRay and tiny fly-out Stinger Nano.

The entire Falcon mother ship configuration, with its fly-out 120m TMS, its docking station for fly-out daughter and sister, a subsea toolbox, tailor-made subsea interchangeable tools using manipulator, and docking-inclusive cleaning device in its tool basket are all fitted into a total system dimension of 1000x1000x850mm.
