The Minerals Management Service (MMS) released an update of the assessment of damage to offshore oil and gas infrastructure caused by Hurricanes Katrina and Rita.

MMS Gulf of Mexico Regional Director Chris Oynes noted that "Today's assessment of damage updates the assessment MMS released on January 19, 2006. Based on additional industry assessments, investigations, and reports, the number of pipelines damaged has risen to 457 from 183. The number of larger diameter pipelines (10 inches or greater) that were damaged has risen to 101 from 64. Thirty-two have returned to service versus the previous number of 22." Tables 1 and 2 (PDF) list the major pipelines that were damaged.

MMS has also revised the number of platforms destroyed from 115 down to 113 (one was mistakenly a well and one was only damaged). Tables 3 and 4 (PDF) list the destroyed platforms. Of these 113, four replacement platforms have been proposed by the operators and approved by MMS to date. These replacement platforms will take the place of eight destroyed platforms with a pre-hurricane daily production of 16,700 barrels per day.

MMS has canvassed the operators of the facilities with largest amount of production still shut-in to provide an estimate of when they might return to production. These are:

Operator Company Facility Name Area Project Date
Shell Mars Mississippi Canyon Block 208 Mid year 2006
Total Matterhorn Mississippi Canyon Block 243 Imminent
Shell Cognac Mississippi Canyon Block 194 4th Quarter 2006
Kerr-McGee Red Hawk Garden Banks Block 876 Imminent

MMS also is releasing the following tally of hurricane-related oil/condensate/chemical spills in Federal offshore OCS waters as reported to MMS and the National Response Center. Six spills of 1,000 barrels or greater were reported; the largest of these was 3,625 barrels of condensate reported by the Gulf South Pipeline Company in the Eugene Island Block 51 area. A total of 146 spills of 1 barrel or greater have been reported in the Federal OCS waters; 37 of these were 50 barrels or greater. No shoreline or wildlife impacts were noted from these spills.

Oynes explained that, "Assessments of pipeline and facility damages are still ongoing, and any updates will be reflected in future announcements. It is likely that additional damage will be reported as underwater damage assessments are completed. These have been delayed because of overwhelmed support resources, such as diving equipment, support vessels, and remotely operated vehicles, but we are moving ahead as expeditiously as possible under the circumstances."
