HOUSTON– TIW Corp. has completed and delivered two large-diameter ball-type safety valves to Marine Well Containment Co. (MWCC) for use with its expanded containment system.
The Class II ball-type hurricane valve is a custom valve design derived from the TIW kelly valve used for drilling operations worldwide. The valves will become a component of MWCC’s containment system for the capture of fluids from an uncontainedsubsea well in water depths to 10,000 ft (3,048 m).
The valves will be used with the riser systems associated with two modular capture vessels. In the event of a hurricane, an extreme loop current, or some other event requiring vessels to leave the wellsite, the valve will add to the vessel’s ability to isolate flow from the subsea production system, safely disconnect, depart the site, and later return and reconnect to resume production operations after the event has passed.
