FAREHAM, UK – A joint project mounted by Subsea 7 and Saab Seaeye has solved the problem of entanglement posed by shifts in current during ROV operations. The engineering team fit powerful thrusters to each tethered management system (TMS) so it can hold position.

The operator dials up a target heading and magnitude of thrust, and the system automatically holds the unit steady, leaving the operator to concentrate on tasking the ROV, the companies say.

Additionally, an auto-heading feature constantly aligns the opening of the TMS with the swimming position of the ROV, orientating itself ready for recovery, and avoiding the risk of the ROV tether running behind the TMS.
