SS-15® BigBore™ II Subsea Wellhead System Brochure

The SS-15 BigBore II Subsea Wellhead is designed for 15,000 psi working pressure and H2S service. The wellhead has a primary landing shoulder and unique multiple-load profile on the lower I.D., which allows all casing weight and pressure loads to be carried at the bottom of the wellhead, with a 7.0 million lb load capacity. The wellhead-restricted I.D. is 18.510 inches. The lower O.D. of the wellhead has a reaction ring to transfer bending loads to the conductor wellhead for maximum resistance to bending. The wellhead can be provided with a Dril-Quip or customer-specified wellhead connector profile.
