TMT Riser Alignment Tool

The TMT Riser Alignment Tool (RAT) is flexible and versatile solution for checking inclination of a riser or similar subsea structures. The RAT can be installed on deck on a riser between a diameter of 150mm (6”) to 350mm (14”) with proper inserts and can be removed easily and quickly subsea by an ROV.
The RAT is electrically isolated so it won`t lead to any corrosion of the host structure. Depending on operational needs it can also employ the default light strap (part number - 0009-0925_01) or if required by customer for tighter stronger fastening, an insulated wire rope (part number - 0009-0925_02).
