Subsea Wellhead Tool
Subsea Wellhead Tool
The TMT Acoustic Smart Level (ASL) tool assists in keeping the drill string vertical by measuring the inclination of the drill string in two perpendicular planes. The transmitter bottle is clamped to the string with a customisable clamp.
The drill string angles are displayed digitally on the front of the transmitter bottle where it can be read by the ROV operator using the ROV cameras.
Inclination information can also be sent acoustically to a listening bottle on the ROV or over the side of the vessel/rig. Inclination data is then transferred to the ROV operators Graphical User Interface on the laptop. Custom software provides a visual representation of the data.
