Abstract: A shear ram assembly for use in a BOP stack. The shear ram assembly includes a ram block disposed within the shear ram housing and having a forward end facing the bore, the ram block movable between an open position, in which the ram block is retracted away from the bore, and a closed position, in which the ram block is extended toward the bore. The blade has a forward surface, a rear surface, a lower shearing edge, and an upper edge, the blade attached to the forward face of the ram block by fasteners extending at an angle relative to an upper surface of the ram block through a portion of the ram block and into the rear surface of the blade, the rear surface of the blade angled so that it is perpendicular to the longitudinal axis of the fasteners.

Abstract: Subsea power and data communications apparatus, subsea wireless sensor hubs assemblies, subsea wireless sensor hubs, and methods of providing power to and receiving data from subsea data gathering devices, are provided. An exemplary apparatus can include subsea sensors/gauges, batteries to power the sensors/gauges, charging circuits for controlling charging of the batteries, one or more BOP control pods, an RTU, and a subsea wireless connection hub. The hub can include a stationary wheel carrying wireless stationary connection members each electrically connected to a battery and a respective subset of sensors/gauges. The hub can also include a rotatable wheel carrying a single wireless movable connection member configured to provide power to each of the stationary connection members and to receive data from the stationary connection members. A motor is provided to rotate the rotatable wheel to position the mobile connection member in front of a selected one of the stationary connection members.

Abstract: Method and subsea sensors display system configured to display data about a blowout preventer (BOP) stack. The subsea sensors display system includes a display panel having plural universal subsea displays, each universal subsea display being configured to display a value measured by a sensor attached to the BOP stack; and a J-box electrically connected to the display panel and configured to provide electrical power to the display panel and to receive data from the display panel. The electrical power is provided from a pod provided on the BOP stack or from a battery when the pod is not available or from a remote operated vehicle (ROV) when connected to the display panel.
