Type 5 Tether Management System

Help With This Product

Product Literature

The Type 5 Tether Management System (TMS) has been developed to provide a compact and weight-efficient solution with high tether capacity. Although it is smaller and lighter than any other current production TMS there is no compromise in the strength of the frame, which remains capable of handling a 9000kg ROV package with 3g rating. It is suitable for all work-class ROVs.

The TMS stores and deploys the ROV tether cable so that the ROV motion is decoupled from motions of the main umbilical to the surface vessel. It allows the ROV to operate at a greater operating radius from the deployment point.

The docking box used on the underside of the TMS has a powerful two stage latching action that structurally locks the ROV to the TMS for deployment and recovery through the sea surface.

The top lifting cone can be a Perry standard design or customer specified bullet, to suit an existing A-Frame.

The Type 5 TMS has a gentle tether route which will maximize the operating life of any matched tether.
