The system allows for the Surface Deployment System depth rating to be increased for 150 metres to 500 metres. Once the CGU is at the required depth it can be release from the Module Running Tool (MRT) to keep constant tension on the guide wires and allow the MRT to be lowered over the SCM on the Subsea Tree.

Benthic Geotech

Submec designed and engineered a Shear Vane Test Tool for Benthic Geotech's PROD system. The tool is 1.9 metres in length and only 58 millimetres in diameter. The shear vane on the end of tool is push into the seabed which automatically starts the program to rotate the shear vane at pre-program speed and time period. At the completion of the set program the tool switches off and the data record is transmitted to the tools memory that can extract when the tool is recovered.
