Abstract: A wellhead bracing system for a subsea well includes a base plate assembly and a wellhead brace assembly. The base plate assembly comprises a top surface, a bottom surface, a base plate aperture, and a plurality of anchor holes. The wellhead brace assembly comprises a vertical plate assembly having a cylindrical shape, a horizontal plate assembly to which the vertical plate assembly is attached, and a vertical support assembly attached to an outer surface of the vertical plate assembly and attached to the top surface of the horizontal plate assembly. Horizontal plate holes of the horizontal plate assembly are configured to attach to studs on the top surface of the base plate to secure the wellhead brace assembly to the base plate assembly. The wellhead bracing system slides onto a wellhead of the subsea well and braces an exterior of the wellhead.

Abstract: A method for remotely evaluating fatigue damage of a subsea wellhead may include obtaining a plurality of values associated with measurements of a parameter associated with the fatigue damage of the subsea wellhead during field operations, wherein the measurements are measured by a sensor device positioned separately from and adjacent to the subsea wellhead; executing an algorithm using the measurements to generate a result; comparing the result of the algorithm with a range of acceptable values; and determining that the subsea wellhead has a potential failure when the result falls outside the range of acceptable values.
