HP1 Macondo Deployment

Called to action on June 12, 2010. Departed Phoenix / Typhoon location in GC237 within 2 days and was operational in MC252 30 days later. 

Permanent modifications to the HP1 will shorten response time from 30 to 10 days.Permanent modifications to the HP1 will shorten response time from  30 to 10 days.

Our goals• Call‐off on Day 1• Response time of 10 days from call‐off to• Response time of 10 days from call‐off to 

in‐service 

HP1 Modifications for Macondo• Fabrication of new buoy• Fabrication of new buoy• Fabrication of water curtain system to

• 450 Te. deck crane; 250 Te., A&R cable and 150 Te. AHC deepwater crane capable of reaching 10,000 ft. 

• Reels hold 3,000 tons of rigid steel pipe up to 14 inches in diameter

• Open deck allows the vessel to carry multiple reels of flexible flowlines

Macondo by the Numbers

80 Barrels of kill fluid pumped every minute through four vessels daisy chained to the Q4000 during the Top Kill operation

285,000 – Man hours Helix ESG and BP staff onboard the Q4000 during the blowout responseg p

32,000 – Barrels of fluid used during the Static Killand cementing operationand cementing operation

135 – Days Q4000 worked at response siteHydrates in the containment dome

1,000,000 lbs. Deepwater Horizon’s BOP lifted from the sea-floor to the Q4000’s deck

280,000 bbls. Oil burned on Q4000 over 33 days operation

Discussion points

• Ideal response resources are locally based, flexible, self supporting and able to respond quickly in event of a subsea spillp q y p

• Industry participation is necessary to modify and prepare assets for specialized responsep p

• Containment response will expand and require industry standardization and research/developmentstandardization and research/development

• A pragmatic approach must be taken as to how much containment capacity and redundancy is actually neededcapacity and redundancy is actually needed

• The perfect solution for every conceivable scenario cannot be prepared Focus should be on flexible systems with quick ability toprepared. Focus should be on flexible systems with quick ability to adapt and respond.
