The FLOT connects to the host ROV using the supplied mounting rails. Control of the tilt and rotate functions is via TMT Hydraulic 5-Function Manifold. The tilt and rotate functions are displayed on the surface laptop GUI. The TMT FLOT is fitted with a proprietary TMT torque tool cradle and table that allows subsea connection and disconnection of a TMT Mk3 Electric Torque Tool without the need to surface the ROV. This allows the ROV to conduct a valve operation during EFL/HFL operations.
The tool can support a payload of up to 500kg. A pair of hydraulic cylinders actuates a mechanism to provide a tilt up of 90°, which keeps the tool within the frame of the ROV during launch and recovery and a tilt down of 90°, which facilitates use with vertical receptacles.
Another cylinder provides ±20° roll.
