Tether Management System

The Tether Management System is easy to maintain

The Tether Management System – TMS makes the ROV more manoeuvrable and increases its range without moving the vessel or rig.

The purpose of the TMS is to lengthen and shorten the tether in order to minimize the effect of cable drag during underwater currents.

The TMS is engaged to the ROV to make handling through the splash zone less hazardous during launch and recovery.

Our Tether Management System – TMS has been developed over a long time period in cooperation with our customers and emerges as one of the most reliable and «easiest» Tether Management Systems on the market.

The TMS design ensures a satisfactory winding which is friendly to the tether and helps extend its lifespan. The Tether Management System is easy to maintain.
