TMT Wellhead Alignment Frame (WHAF)

TMT Wellhead Alignment Frame (WHAF)

 
 
The TMT Wellhead Alignment Frame (WHAF) is designed to be attached to subsea infrastructure on the rig and then lowered through the moonpool.
 
Once subsea, the ROV is able to fly up and press against the bumper unit; from there, the ROV can give a heading to determine the orientation of structure.
 
Once the structure has been landed, the ROV uses the Bullseye to check that the angle of the structure is within acceptable limits. 
 
An optional ROV docking probe interface compliant with ISO 13628-8:2002(E) is available.
