CTC Marine: RT-1 Rock Trencher

The RT-1 Rock Trencher is the worlds largest tracked underwater vehicle in the world. With 2.35MW of effective trenching power it is designed specifically for the burial of pipelines/trunklines in hard soil regions. The innovative, unique triple chain cutter configuration defines a wide, sloping V shaped trench allowing the stabilisation and protection of large diameter pipeline for trunkline burial. This methodology delivers improved economic and environmental benefits in comparison to other protection methodologies. RT-1s advanced designed pipe lifting technology allows the lift of heavy flooded pipelines. The unique cutting system is adaptable to allow burial of flexible products such as umbilicals and flowlines in a variety of soils. CTC operate some of the worlds largest, most technically advanced marine trenching vehicles and vessels enabling us to complete workscopes ranging from trenching, to a more comprehensive subsea protection service for the international offshore construction industry.
