Latest Patents
Chou's latest patents include a drilling riser centralizer and a wellhead body lockdown method. The drilling riser centralizer is a centralizing device designed for a riser of an offshore well platform. It features a frame that defines an opening through which the riser passes from the platform to a subsea wellhead. The centralizing device includes a centralizing ring with an inner diameter greater than the outer diameter of the riser, allowing the riser to be passed longitudinally through it. The adjustable mounting means enable the centralizing ring to be positioned at different locations within the opening. A roller assembly is carried upon the riser as it is lowered, engaging the centralizing ring to limit lateral movement while allowing longitudinal movement.
The second patent, the wellhead body lockdown, involves a preloaded connection for supporting an annular body from an annular suspension joint. This connection comprises an actuating ring, a split locking ring, and a retaining nut, which are strategically positioned between the annular body and the suspension joint. The connection is preloaded by applying an axial force to the actuating ring, causing the locking ring to expand outwardly, thus preloading the annular body in compression and the suspension joint in tension.
