Zero Visibility Operations Planning - DrillSafe

Solution Criteria
• To overcome the potential problems associated with
Strong Currents and Zero Visibility a solution had to meet
the following criteria;
1. Determine Relative location of equipment on seabed
(not absolute location)
2. Wireless inclination measurements on TGB and PGB
3. “Pictures” in a zero visibility environment
4. ROV Friendly
5. Easily Deployable
6. Cost Effective (Stena Clyde spread rate on Petrel-7
~$25,000/hour)
