Subsea Tooling
The TMT Mega Digger moves high volumes of material around subsea structures in the fastest most effective way possible. The unit is mounted to the front of the ROV using a multi position mounting frame fitted with a front bumper.
The ROV then positions itself up current of the material to be removed and secures itself to the structure by use of the TMT ROV Grabber unit or manipulator. If no structure is available then the ROV holds seabed position using the TMT SRPS (patent pending) system.
TMT can customise the tool to suit your requirements.
