Abstract: Provided is a life cycle tracking system including a memory and a processor. The memory includes instructions that, when executed by the processor, cause the processor to perform certain operations. For example, the operations can include effecting a change in a first database including data related to a set of components installed on a blowout preventer stack, in response to a drag and drop operation having been performed on a human machine interface. The change can include associating information from a second database to the first database. The second database includes data related to a set of spare components.

Abstract: A control system for a subsea blowout preventer (BOP) positioned in a lower stack, the lower stack releasably engaged with a lower marine riser package (LMRP). The control system includes a surface logic solver positioned at or adjacent the surface of the sea that generates commands for operating the subsea BOP, a first subsea logic solver attached to the LMRP and in communication with the surface logic solver so that the first subsea logic solver receives the commands from the surface logic solver, and a second subsea logic solver attached to a hydraulic control unit in the lower stack. The second subsea logic solver is in hydraulic communication with the subsea BOP, and the first subsea logic solver so that the second subsea logic solver receives the commands from the first subsea logic solver and implements the commands by activating the hydraulic control unit to operate the BOP.

Abstract: An induction subsystem for a conveyor sortation system and method of inducting articles includes providing a plurality of tandem conveying surfaces. The speeds of the conveying surfaces are individually controllable. At least one sensor is provided for sensing articles on at least one of the conveying surfaces. A control is responsive to the at least one sensor for controlling the speeds of said conveying surfaces in a manner that controls relative positions of articles. The control defines a plurality of feedback-gapping algorithms. Each of the feedback-gapping algorithms is defined between adjacent conveying surfaces for adjusting relative speeds of those adjacent conveying surfaces as a function of at least one parameter of the articles. The control controls relative positions of articles with the feedback-gapping algorithms beginning with a pair of adjacent conveying surfaces and cascading through adjacent pairs of adjacent conveying surfaces.

Abstract: A fiber optic sensor coil is wound from a length of optical fiber with the mid-point of the optical fiber at the mid-point of the innermost layer of the coil and subsequent layers of the coil each have alternating turns of the two sections of the fiber emanating from the mid-point. The layers of alternating turns are formed by first winding a portion of one segment in such a fashion that adjacent turns are spaced apart by a distance equivalent to the diameter of the optical fiber. The layer is completed by winding a portion of the other segment such that the turns of the other segment are disposed between adjacent turns of the one segment. The number of turns in adjacent layers are unequal such that the turns of a next layer are arranged in grooves formed between two adjacent turns of optical fiber in the previous layer.
