Abstract: In some embodiments, a controller is configured to be operably coupled to a series of safety relays. Each safety relay is coupled to a machine from a plurality of machines. The controller is configured to receive a signal indicative of a potential collision between any machine from the plurality of machines that is coupled to the at least one of the safety relays that was activated. The controller is configured to send, in response to the signal indicative of the potential collision, a signal to at least one of the safety relays from the series of safety relays to activate the at least one of the safety relays, thereby stopping motion of any machine from the plurality of machines that is coupled to the at least one of the safety relays that was activated.

Abstract: In some embodiments, a method for executing an emergency disconnect sequence in shallow water depth includes unlatching a lower marine riser package (LMRP) of a blowout preventer (BOP) from a lower stack of the BOP. The BOP defines a wellbore fluidically coupled to the subsea wellhead. A tubular is disposed within the wellbore. The method further includes shearing the tubular and sealing the wellbore. In response to an indication that a vessel operably coupled to the BOP has failed to keep station, an unlatch sequence and a shear and seal sequence are initiated, such that each sequence occurs at least partially simultaneously. The unlatch sequence includes disconnecting the LMRP from the lower stack, and the shear and seal sequence includes activating the lower stack to shear the tubular in less than about one second and seal the wellbore.

Abstract: The system for making or breaking the riser includes a robotic system. The robotic system includes one or more robotic arms configured to be disposed on a spider deck, and one or more riser-connection manipulation tools each having a camera and being configured to manipulate a riser connection, the camera being configured to capture an image of an object, wherein each robotic arm is configured to couple to one riser-connection manipulation tool. Further the system for making or breaking the riser includes a control system. The control system includes a robot controller in communication with the one or more robotic arms and configured to control the one or more robotic arms. The system for making or breaking the riser is configured to analyze the image to determine the location and orientation of the object and transmit the location and orientation of the object to the robot controller.

Abstract: A subsea energy storage for well control equipment, wherein stored energy near a well on the sea floor monitors and activates well control equipment independently of, or in conjunction with, hydraulic energy. Energy to the subsea energy storage can be supplied by surface umbilical, remotely-operated vehicle, or by subsea electrical generation from stored hydraulic energy. Stored electrical energy may also recharge stored hydraulic energy. A subsea control system is configured to record data, compare the data to predetermined event signatures, and operate the well control equipment with stored electrical energy.

Abstract: A derrick structure may include a plurality of drilling rotating/hoisting/circulation (RHC) traveling block/top drive like systems that can move between and are fully functional on multiple well centers. With such a configuration, one RHC can be disconnected from the drill lines and suspended in the drilling derrick allowing two hoisting systems with separate motors to function simultaneously on a single well center, thus doubling the lifting capability on that well center. For example, one traveling block may be suspended and its associated drill line and winch coupled to another traveling block on a different well center.

Abstract: An enhanced riser control system may employ electrical tensioners coupled to a drilling riser by wires. The electrical tensioners may provide quick response to a tension controller to handle positioning of the drilling riser. The electrical tensioners of the enhanced riser control system may be combined with hydro-pneumatic tensioners in a riser hybrid tensioning system. A controller within the enhanced riser control system may be configured to distribute tension to electrical tensioners and to control electrical tensioners to adjust the length of the first and second wires. The electrical tensioners may be used, for example, to suppress vortex-induced-vibration (VIV) and control drilling riser recoil.

Abstract: A hybrid power plant is characterized by a substantially constant load on generators regardless of momentary swings in power load. Short changes in power load are accommodated by DC components such as capacitors, batteries, resistors, or a combination thereof. Resistors are used to consume power when loads in the power plant are generating excess power. Capacitors are used to store and deliver power when the loads in the power plant demand additional power. Reducing rapid changes in power load as seen by the generators allows the generators to operate at higher efficiencies and with reduced emissions. Additionally, power plants employing combinations of generators, loads, and energy storage devices have increased dynamic performance.

Abstract: A system and method for automatically preventing a collision between objects is described. One or more images of a working space may be collected, and a first object may be identified based on the one or more images. Three-dimensional coordinates of the first object may be determined, and a virtual boundary enclosing the identified first object in a three-dimensional coordinate system may be generated based on the three-dimensional coordinates of the first object, wherein the virtual boundary specifies a volume in the working space that a second object in the working space should not occupy. The coordinates in the three-dimensional coordinate system corresponding to the generated virtual boundary may be transmitted to a second processor, and the second processor may control the second object to perform an operation in the working space that includes the first object without contacting the virtual boundary of the first object.
