A method of seal condition monitoring may determine the state of the annular seal, the state of one or more sealing elements, take actions to maintain the annular seal as one or more sealing elements transition from new to worn, and provide advance notice of the impending failure of one or more sealing elements so as to avoid a catastrophic annular seal failure while the marine riser is pressurized. Advantageously, operations may be conducted proactively rather than reactively, and one or more sealing elements may be replaced well in advance of failure, but potentially later than a conventional maintenance schedule would dictate. The one or more failing sealing elements may be proactively replaced without depressurizing the marine riser, prior to seal failure or replacement may be planned well in advance and coordinated with other rig operations to improve efficiency and maintain the safety of the drilling rig and personnel.

Seal condition monitoring

A pressure containment device includes a sealing element. The sealing element includes a longitudinal axis, a substantially annular cross-section arranged perpendicular to the longitudinal axis, a radially inwardly facing interior surface having a plurality of recesses, a radially outwardly facing exterior surface, a first end surface having a plurality of recesses, and a second end surface. The first end surface and the second end surface are each arranged to extend from the radially inwardly facing interior surface to the radially outwardly facing exterior surface. The first end surface and the second end surface are arranged at opposite ends of the sealing element.
