TTS-2/125 Series Tensioner
2-track system
The MDL TTS-2/125 Series Tensioner is a 25Te line pull, 2-track system for the installation or recovery of flexibles, cables, umbilicals and steel pipe products.
The tracks are fitted with 'V' shaped pads and operate by gripping the product between the opposing track carriages with hydraulic cylinders.
The system is compact in size with the top track rotating out of the firing line to provide a large area for accepting the product.

Key Benefits
User-friendly: Tracks driven by hydraulic motor/brake/gearbox drive assembly to deploy or retrieve the product.
The two-track carriages are mounted in the main structural frame. This isconnected to the mounting frame with low shear mounts and load cell pins for accurate product load information.
The system is compact in size with the top track rotating out of the firing line to provide a large area for accepting the product.
Both tracks open hydraulically to load/unload product and close to grip the product when operational.
The track carriages are mounted on kingpins so that they can pivot if the outside product diameter tapers.
Thanks to this design, the tensioner can be top loaded or in line loaded with the product.
Safe: E-stops mounted at each side of the base frame allowing for safe control of operations.
Project Focused: Supplied with dedicated electro-hydraulic powerpack, which drives the track motors and operates the track cylinders.
Remote operator’s control panelwhich can be fitted within an existing control room or dedicated cabin.
Quick connect/release package of interconnecting cables and hoses completes the basic system.
Facility for data logging and remote interrogation subject to set-up and bandwidth on-board vessel.
Easily mobilised: Unit is road transportable or can be shipped in 40ft flat rack containers.
Optional Extras: As each project has different requirements, the following optional extras can be supplied with,he tensioner:
