Abstract: A navigation system includes a support structure configured to be positioned at a sea floor. The navigation system also includes multiple transducers coupled to the support structure at fixed locations and configured to emit multiple reference signals. The navigation system further includes a transducer coupled to a movable subsea vessel and configured to receive the plurality of reference signals. A controller includes a processor and a memory, and the processor is configured to determine a position of the movable subsea vessel relative to the support structure based on the multiple reference signals.

Abstract: A blow out preventer (“BOP”) includes a vertical bore extending through the body, a ram cavity intersecting the bore, and a port located below the ram cavity. A sensor assembly is locatable in the port and is configured to monitor the position of at least one opposing ram contained in the BOP. At least one of the rams includes a detection feature on a lower surface of the ram which is distinguishable from the rest of the ram body, other features of the BOP, and any debris in the bore of the BOP. The detection feature is detectable by the sensor assembly. The detection feature may include a visual indicator.

Abstract: A pre-load monitor is arranged for use between a between a washer face of a fastener and a bearing surface of a fixture arranged to receive a portion of a shank of the fastener. The pre-load monitor, which can be in the form of a washer, includes a piezoelectric generator which generates the electrical power to measure, monitor and report the pre-load. The resulting electrical power produced is proportional to the pre-load and can be stored to provide the energy required to function electrical, electronic and communication circuits included in the washer. Alternatively, the pre-load monitor can be a half- or split ring (or a C-ring) constructed similarly to that of the washer, or the ring can be a two-piece gasket construction that includes an array of the washers.

Abstract: A system for a blowout preventer (BOP) stack assembly includes one or more pairs of ultrasonic transducers coupled to a body that is configured to support a movable component of the BOP stack assembly, wherein each pair of ultrasonic transducers comprises a first ultrasonic transducer disposed on a first side of the body and a second ultrasonic transducer disposed on a second side of the body, opposite the first side. The system also includes a controller configured to receive a first signal indicative of a position of the movable component from the one or more pairs of ultrasonic transducers, to determine the position of the movable component based on the first signal, and to provide a first output indicative of the position of the movable component.

Abstract: The present disclosure generally relates to an assembly and method for monitoring the position of one or more opposing rams in a ram-type blowout preventer (“BOP”) during opening and closing operations. In particular, a BOP includes a vertical bore extending through the body, a ram cavity intersecting the bore, and a port located below the ram cavity. A sensor assembly is locatable in the port and is configured to monitor the position of at least one opposing ram contained in the BOP. At least one of the rams includes a detection feature on a lower surface of the ram which is distinguishable from the rest of the ram body, other features of the BOP, and any debris in the bore of the BOP. The detection feature is detectable by the sensor assembly. The detection feature may include a visual indicator.

Abstract: A monitoring system includes a subsea laboratory configured to be positioned and operated below a sea surface. The subsea laboratory includes a housing, a fluid chamber within the housing and configured to receive a fluid from subsea drilling or production equipment, and a sensor within the housing and configured to generate a signal indicative of a characteristic of the fluid. The monitoring system also includes a controller having a processor configured to receive and to process the signal to determine the characteristic of the fluid, to determine an appropriate output based on the characteristic of the fluid, and to provide a control signal that causes an indication of the output via a user interface of a remote base station positioned above the sea surface.
