US Patent Issued to Chevron U.S.A. on Sept. 30 for "Wellhead fatigue damage estimation using metocean data" (California, Texas Inventors)

ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,428,947, issued on Sept. 30, was assigned to Chevron U.S.A. Inc. (San Ramon, Calif.).

"Wellhead fatigue damage estimation using metocean data" was invented by Wangming Lu (Katy, Texas) and William Stephen Averill (Cypress, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The wave characteristics of the water (e.g., ocean) above a wellhead may be used to determine a wave-induced wellhead fatigue damage rate for the wellhead, and the current profile of water around a riser connected to the wellhead may be used to determine a riser vortex-induced vibration caused fatigue damage rate for the wellhead. The wave-induced wellhead fatigue damage rate and ...
