Tether Management Systems

Sub-Atlantic · Model Garage TMS 1, 2, 3; Top-Hat Type IV, V, VI; Garage Type B, C

Top-Hat and Garage type TMS for observation and work-class ROVs, rated to 3000m and 4000m, decoupling the ROV from surface vessel motion.

Description

A Tether Management System (TMS) stores and deploys the ROV tether so that the ROV is decoupled from the surface vessel's motion and can operate at a larger radius. FET offers Top-Hat and Garage type systems for electric observation-class and hydraulic work-class ROVs, with optional thrusters on some models for greater operating radius.

Key features

  • Design focus on tether path geometry, tether load sensing and proportional speed control for reliability
  • Garage TMS 1, 2 and 3 (observation ROV): rated to 3000 m, safe working loads of 2000 to 3500 kg
  • Top-Hat Type IV, V and VI and Garage Type B and C (work-class ROV): rated to 4000 m, safe working loads from 11000 kg to 13500 kg

Applications

Deep-water ROV operations from offshore support, survey and construction vessels.

Specifications

Depth rating3000m (Garage TMS 1-3); 4000m (Top-Hat IV-VI, Garage B/C)
Safe Working Load2000kg – 13500kg depending on model
