    Abstract: An integrated well construction system for constructing a well includes equipment controllers which control drilling equipment, and a process controller operatively connected to the equipment controllers. The process controller includes a drilling control module which defines an operational drilling scheme and a task manager module. The operational drilling scheme has a first part to control the drilling equipment, a second part with manual tasks and/or automated tasks to be performed, and a relation between an execution of control of the drilling equipment via the first plan and of manual tasks and/or the automated tasks via the second plan. The task manager module has a user interface, a task refinement component which updates the second part, and a user interaction device which provides a manual addition of new manual tasks and/or new automated tasks, and a removal or amendment of at least one of the manual tasks and/or the automated tasks.

    Abstract: A method for controlling drilling operations includes defining operation zones in a drilling operation area, each operation zone having equipment operating therein, and repeatedly performing the steps of: determining a position of at least one person in the drilling operation area, determining whether the respective determined position is within any of the operation zones and associating each person to the operation zone in which the person is located, determining whether the respective determined position is within a safety zone in proximity to the equipment, determining at least one action to be performed with regard to each operation zone in which the person has been determined to be present, and transmitting at least one control signal for controlling the drilling operations based on the at least one action determined. The at least one action is determined dependent on whether or not the position of the person is in the safety zone.

    Abstract: A gate valve for controlling a flow of a fluid. The gate valve includes a valve body with a first seat pocket and a flow bore, a gate which is movable so as to intersect the flow bore, a seat with a gate end and a body end, a plate with an opening which is positionable on the seat at the gate end, and a plate retainer which is positionable between the seat and the plate so as to prevent an axial movement between the seat and the plate with respect to an axis of the flow bore. The flow bore extends through the valve body for the flow of the fluid. The gate end is arranged to face the gate, and the body end is positionable within the first seat pocket of the valve body.

    Abstract: A hoisting system includes a hoisting cylinder assembly which is arranged vertically. The hoisting cylinder assembly includes at least one hoisting cylinder, a lower part, and an upper part, the upper part being moveable in relation to the lower part. At least one sheave is arranged in the upper part of the hoisting cylinder assembly. A winch which includes a base is fixed in relation to the lower part. A first wire is operatively connected to the winch and extends from the winch via the at least one sheave to a yoke so as to suspend the yoke from the at least one sheave.

    Abstract: A device for suspending a tubular from a floating vessel includes a first element which carries the tubular, a second element supported by the floating vessel, and a compression element which forms a connection between the first element and the second element. The compression element is pre-tensioned in an end stroke position so that, when the compression element is subjected to a force from the tubular which is below a pre-defined threshold force, the connection formed by the compression element between the first and second element is a rigid connection, and, when the compression element is subject to a force from the tubular which is higher than the pre-defined threshold force, the connection formed by the compression element between the first and second element is a compressible connection.

    Abstract: A self-aligning apparatus for a lifting system includes a structure which includes a first element having a first projecting free end and a second projecting free end which each receive at least one sheave at a point of attachment to the first element, and at least two first points of rotation. The at least one sheave cooperates with at least one wire. The at least two first points of rotation are arranged above the at least one sheave's point of attachment to the first element so that the apparatus self-aligns during use in an uneven loading event.

    Abstract: A device which moves a die between a retracted position, thereby releasing the die from the device, and an advanced position, thereby fixing the die to the device. The device includes an inner body comprising an inner body wall, and an inner body set of inclined faces. A body comprises a longitudinal groove. The longitudinal groove comprises an inner wall which contacts the inner body wall. An intermediate body comprises a first longitudinal side comprising a longitudinal side set of inclined faces, and a second longitudinal side arranged opposite thereto. The first longitudinal side cooperates with the inner wall. The second longitudinal side cooperates with a first side of the die. The longitudinal side set of inclined faces cooperates with the inner body set of inclined faces. A relative movement between the intermediate body and the inner body moves the die between the retracted position and the advanced position.

    Abstract: A method for scheduling a maintenance event for a machine used in drilling which includes providing a first well plan for a first well to be drilled over a first time period (tA) and a second well plan for a second well to be drilled over a second time period (tB), controlling a first computer program module for determining a projected first duty profile for the machine in the first time period and a projected second duty profile for the machine in the second time period, controlling a second computer program module for scheduling a maintenance event (tM1) for the machine based on the projected first duty profile and the projected second duty profile, and creating a new maintenance event (tM2) at a time prior to the second time period if the maintenance event (tM1) falls within the second time period.
