VHSS Spooling System

VHSS Spooling System


The TMS-PF (Power Fleeting) is compatible with all Subsea Innovation Launch and Recovery Systems as well as a variety of other LARS and ROV systems. 

The TMS-PF is a proven design with over 20 units in operation worldwide. This unit is also available in a lightweight model or a fully stainless steel option. The TMS-PF is a reliable easily maintained system with proven success worldwide over several decades.

The system is designed to be cable friendly and lightweight sheaves guarantee that the minimum bend radius of the tether is not exceeded. The hydraulically driven power sheave is positioned at the exit of the tether to avoid any potential drive slippages.

The docking assembly incorporates two sets of latching fingers with one set being failsafe to prevent accidental dropping of the vehicle during launch and recovery. Subsea Innovation also design and manufacture the compensators and electrical junction boxes that are integral to the TMS.

These units can be fully fitted by Subsea Innovation or they can incorporate client control systems or specific components.
