The present disclosure describes methods and systems, including computer-implemented methods, computer program products, and computer systems, for managing corrosions in oil and gas pipelines. One computer-implemented method includes: obtaining, by one or more hardware processors, a first dataset and a second dataset; performing, by one or more hardware processors, a feature mapping operation that matches one or more corrosion features in the first dataset to corresponding features in the second dataset, wherein the feature mapping operation comprises a joint matching process, a girth weld coordinate transformation process, and an iterative closest point (ICP) process; determining, by one or more hardware processors, a corrosion growth rate based on an output of the feature mapping operation; and outputting, by one or more hardware processors, the output of the feature mapping operation in a user interface.

Managing pipeline corrosion in oil and gas production

A cleaning device that passively self-adjusts to improve biofoul removal across curved, non-uniform, or irregular underwater surfaces. The cleaning device includes a motor, one or more shafts coupled to the motor and coupled to one another via at least one universal joint, and a cleaning mechanism for removing biofoul from the target surface. The cleaning device includes an alignment mechanism that restricts the cleaning mechanism's movement to improve biofoul removal. The alignment mechanism can include bearings, spring components, dampening material, adhesion components, floatation objects, or a combination thereof.

Underwater marine growth brushing mechanism with passive self-adjust for curved surfaces

This application discloses integrated probes and probe systems, which can be attached to the robotic arms of a remotely operated vehicle to perform both cathodic protection (CP) voltage measurements and ultrasonic testing (UT) thickness measurements at an underwater surface. In some embodiments, the integrated probe system couples an inner and outer gimbal together such that one or more electrically conductive legs pass from the outer gimbal through the inner gimbal. These legs are arranged about an ultrasonic sensor which extends from the front surface of the inner gimbal. When the integrated probe contacts the underwater surface, both the ultrasonic sensor and at least one leg contact the surface, thereby providing substantially simultaneous CP and UT measurements.

Integrated ultrasonic testing and cathodic protection measurement probe

A system for underwater remotely operated vehicles (ROVs) and wirelessly controlled subsystems is provided. The system comprises an ROV and a subsystem mounted to the ROV. The ROV includes a microcontroller, a main battery, and a transmitter-receiver. The subsystem includes a controller and a transmitter-receiver. The ROV is configured to communicate wirelessly with the subsystem via signals transmitted between the ROV transmitter-receiver and the subsystem transmitter-receiver. The system can further comprise a control center having a transmitter-receiver configured to communicate wirelessly with the ROV transmitter-receiver and the subsystem transmitter-receiver. The system can further comprise at least one relay module configured to relay signals between the transmitter-receivers of the system. The ROV of the system can also be configured to wirelessly transfer power from the main battery to the power source of the subsystem, such as by resonance coupling.
