Outcomes & Lessons<br />
• LBL Array was easy to deploy<br />
• Rig based USBL beacon not designed to work on ROV –<br />
positioning of LBL beacons not accurate<br />
• Absolute Calibration of the LBL array from a MODU is difficult,<br />
however this was only required this time due to USBL beacon<br />
on ROV not functioning as intended<br />
• Multi-beam sonar did not work as expected (earth fault)<br />
• Inclinometers were effected by currents &/or Drilling Vibration<br />
– giving erroneous readings initially<br />
• Tracking of casing location worked well<br />
• LBL Technology was proven as viable for this application<br />
