Untangling Underwater ROV Cables

The risk of cable snarl-up during multiple ROV operations beneath the waves is avoided in a tether management system (TMS) design breakthrough. The solution came from a joint project mounted by Subsea 7, one of the world’s leading subsea engineering and construction companies, and world-leading ROV manufacturer, Saab Seaeye.     Together they solved the problem of entanglement posed by shifts in current during operations when a number of TMS cages carrying their ROVs are lowered from a single vessel.    With up to six TMS systems working at any one time, an operator has to contend with a multi-dimensional...

Sub-Atlantic ROV Contract

Oceanteam 2000 Limited has placed a substantial order with Sub-Atlantic Limited, for five ROV-systems. The range of systems purchased includes the Comanche system, one of the latest developments by Sub-Atlantic, utilising proven technology already in use on its Mohican ROV. This system will be fitted with Orion manipulators from Schilling Robotics Inc., an Alliance partner with Sub-Atlantic Limited. These industry-recognised manipulators will allow Oceanteam 2000 to undertake projects requiring a greater degree of intervention than is currently possible with other electric ROVs commonly in use. The full range of systems ordered by Oceanteam 2000 includes the Mohawk, Super Mohawk and... (read more)

ROV Bathes in Whisky

McPherson Ltd, one of the biggest whisky road hauliers in Scotland, have purchased an AC-ROV 100 to examine the internal welds, baffles and valves of their tankers to meet the UK period inspection requirements. Ian Jamieson, Fleet Engineering Director of McPherson Ltd, said that using the AC-ROV avoids the high risk ‘man-in-tank’. Ian sees the AC-ROV 100 as the way forward for capturing evidence of the inspection. The date and time marked video survey is recorded real-time onto a SD card built into the AC-ROV system. The file can be transferred or referred to in the future by any auditing... (read more)

AC-ROV Thruster Upgrade

The AC-ROV has a centreless thruster design as there is no motor in the flow path. Existing AC-ROV users from a variety of industrial sectors were selected to field test the "Mark 2" thruster, reporting greater vehicle speed, power and excursion capability without compromise of control or stability.     The Mark 2 thruster will be fitted to all new-build AC-ROV's as standard and is available as a straight change-out component to all existing users.   The benefits are that thrust is significantly greater than from a same size shaft-mounted propeller, thrust is equal in both directions, and as AC-ROV...
