"Hurricane Ivan swept through the Gulf of Mexico on September 14-16, 2004. The hurricane's eye passed almost directly over Chevron Corporation- operated Petronius platform in Viosca Knoll block 786, about 130 miles southeast of New Orleans, damaging rig crew quarters, deck structures and production equipment.
Petronius, which averaged 42,000b/d of crude oil and 65mmcf/d of gas before the hurricane - approximately 3.7% of the total daily production from the Gulf of Mexico - was totally shut-in. 3D laser scanning was used to assess the damaged structures and equipment on the platform - the technique shortened the expected repair schedule by 24 days compared with traditional methods and helped remove the structural steel repair from the critical path."
