Abstract: A seal monitoring apparatus is provided. The seal monitoring apparatus includes one or more pressure sensors and a controller in communication with the one or more pressure sensors. The one or more pressure sensors is mounted at a seal of a turbine to measure pressure on a first side of the seal and/or a second side of the seal. The controller is configured to receive pressure data from the one or more pressure sensors and determine a condition of the seal based at least in part on the pressure data. The controller is configured to output a signal upon determining a change in the condition of the seal.

Abstract: The subject matter described herein relate to a segmented piston seal system. The segmented piston seal includes a first semi-circular section (FSCS) that includes a first locking structure at opposite ends of the FSCS. The segmented piston seal includes a second semi-circular section (SSCS) that includes a second locking structure at opposite ends of the SSCS. The first and second locking structures are configured to lock the FSCS and the SSCS together to form a piston seal.

Abstract: A system for use in servicing a turbomachine, the system including a first tubular body including an interior channel, and a second tubular body. The first and second tubular bodies are bendable between a neutral shape and a biased shape. The bodies are bent when in the neutral shape. The second tubular body includes a tip end, and the second tubular body is translatable within the interior channel. The first tubular body and the second tubular body are rotatable to selectively orient the tip end in multiple degrees of freedom. The system also includes a steering cable extending from the tip end, wherein the steering cable biases the tip end for selective orientation in additional degrees of freedom.

Abstract: A blind shear ram includes an upper carrier including an upper blade and a lower carrier including a lower blade. The upper carrier and the lower carrier are positionable in a first position in which the upper carrier and the lower carrier are spaced apart and a second position in which the upper carrier and the lower carrier seal a wellbore. The upper blade and the lower blade are configured to cut at least one pipe and at least one cable when the upper carrier and the lower carrier move between the first position and the second position. At least one of the upper blade and the lower blade includes a textured surface configured to induce friction between the at least one cable and the blade.

Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes an elastic layer having a first elasticity. The elastic layer is configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the first carrier and the second carrier are in a closed position. The seal also includes an anti-extrusion structure coupled to the elastic layer. The anti-extrusion structure has a second elasticity less than the first elasticity. The anti-extrusion structure includes a plurality of ribs spaced along a longitudinal axis of the anti-extrusion structure. The plurality of ribs define a plurality of spaces configured to receive portions of the elastic layer.

Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes an outer layer configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the blind shear ram is in a closed position. The outer layer has a first stiffness. The seal also includes an inner layer spaced from the outer layer. The inner layer has a second stiffness. The seal further includes an anti-extrusion structure extending between the inner layer and the outer layer. The anti-extrusion structure has a third stiffness greater than the first stiffness and the second stiffness. The outer layer covers the anti-extrusion structure.
