FLORENCE, Italy-- VetcoGray has developed the MS-800 Fullbore Subsea Wellhead System for deepwater applications for increased casing load and higher pressure capacities. With the capacity to withstand 8 million pounds of load on the wellhead, the MS-800 is designed to help drillers reach deepwater targets in such regions as the U.S. Gulf of Mexico and offshore Brazil, says the company.
VetcoGray says the new system increases the casing load capacity to 2 million pounds for the first position casing hanger and the 16-in. casing hanger, while also increasing the pressure capacity for the 16-inch hanger from 6,500 to 10,000 psi (45 to 69 MPa). Also, the load ring configuration was improved on all three casing hangers to improve actuation, says the company.
"We believe all of these capacity and performance improvements will enable the MS-800 to set new standards for the deepwater drilling industry," said Gary Shaw, Technology Leader for VetcoGray. "We have developed this product in response to the growing industry need for technology to exploit subsea oil and gas fields at depths of 30,000 ft (9,144 m) or more."
