    摘要： Systems: and methods for decreasing bending stress in flange bolting for a connection between a flange and an adjacent piece of equipment is provided. The flange connection includes a single flange with multiple bolts extending: therethrough. The bolts are threaded into the adjacent piece of equipment at one end, and a nut is disposed at an opposite end. of each bolt to provide a means for tightening and/or securing the flange connection. The equipment to which the flange is attached may include subsea well equipment with relatively large outer diameters. The disclosed flange connection utilizes: an initial region of a counterbored (or unthreaded) hole in the mating equipment piece just prior to the start of the thread formed through the equipment. Additionally, a compound hub flange connection is disclosed to further reduce the bending stress on the bolts.

    摘要： Systems and methods for coupling subsea tubular members together are provided. An apparatus may be used to properly orient and/or provide communication between a first subsea tubular member that is being landed on a second subsea tubular member. An apparatus for coupling subsea tubular members may include an alignment sub and a corresponding alignment member. The alignment sub includes: a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, one or more couplings coupled to at least one end of the alignment sub, and an orientation profile disposed on a surface of the alignment sub. The alignment member has a profile designed to interface with the orientation profile of the alignment sub. One of the alignment sub and the alignment member remains stationary while the other rotates relative to the stationary structure.

    摘要： Systems and methods for landing a tubing hanger in a wellhead and then orienting a tree (or spool, or flowline connection body) relative to the tubing hanger while landing the tree on the wellhead are provided. This alignment is accomplished without the use of either a tubing spool or a BOP stack with an orientation pin. The tubing hanger alignment devices may be used to orientate the tree as the tree is landed so that the couplings and stabs between the tree and the tubing hanger line up with each other just at the moment of landing.
