Mad Dog   Project Description

 

BP Mad Dog is a truss spar with 12 wells in Green Canyon 782 located in approximately 4,500 feet of seawater, and 190 miles SE of New Orleans, Louisiana.

 

The spar hull is anchored by an 11-line taut mooring system with synthetic mooring lines attached to suction piles.

 

The Mad Dog drilling rig module (DRM) comprised a drilling equipment set (DES), skid beam structure (SBS) and drilling support module (DSM). The DES of the existing DRM was lost during hurricane Ike in 2008.

 

Saipem’s scope of work for this contract was to remove the existing DSM (with the SBS attached) from the Mad Dog spar, place and seafasten it on a transportation barge and then transport it to shore for offloading. After loadout of the new DRM on to a transportation barge, by the rig fabricator in Corpus Christi, Saipem transported it to the Mad Dog site and installed it on to the Mad Dog spar.

 

The vessel used for the removal of the existing DSM and installation of the new DRM is the Saipem S7000
