摘要： A method of operating a drilling system includes suspending a tubular drill string from a travelling assembly into an opening on a drill floor, operating a sensor to measure and to provide a first signal, providing a second signal, and comparing the first signal with the second signal. The travelling assembly is a part of a hoisting system. The first signal represents an acceleration or a velocity of the tubular drill string in a direction into or a direction out of the opening. The second signal represents an operational parameter of the hoisting system. The operational parameter is indicative of a vertical speed or of a vertical acceleration of the travelling assembly.

摘要： A lifting arm arrangement for lifting a pipe includes a pipe stacking tool comprising a first end, a second end, and a pipe handling head arranged at the second end. The pipe handling head is configured to grip around the pipe. A gripper head is connected to the first end of the pipe stacking tool. A tilt shaft is configured to connect the pipe stacking tool and the gripper head so as to form an articulated joint. The articulated joint comprises a locked position in which the pipe stacking tool is prevented from tilting about the tilt shaft, and a neutral position in which the pipe stacking tool is allowed to tilt about the tilt shaft.

摘要： A method for detecting an influx in a wellbore with first and second pressure transmitters arranged in a fixed vertical distance in relation to each other. The method includes calculating an expected density of a return flow between the first and second pressure transmitters, continuously measuring an actual density of the return flow based on a measured pressure at the first and second pressure transmitters, comparing the calculated expected density of the return flow and the measured actual density of the return flow to determine the influx in the wellbore, and predicting a probability of hydrates forming in the well by measuring a temperature via a temperature transmitter arranged in a section of the well adjacent to the first and/or the second pressure transmitter, and using the temperature together with the measurements from the first and second pressure transmitters.

摘要： A lifting arm arrangement includes a gripper head arm, a lifting arm, and a lifting cylinder. A gripper head is fastened to a first gripper head arm end. A first lifting arm end is pivotally connected to the gripper head arm. A second lifting arm end is pivotally connected to a stationary lifting cylinder part. A second gripper head arm end is pivotally connected to a movable lifting cylinder part. The stationary lifting cylinder part comprises a cylinder with a cylinder cavity having first and second cylinder openings. A piston rod with a piston is arranged in the cylinder cavity. A first piston rod portion projects from a first piston end of the piston. A second piston rod portion projects from an opposite second piston end of the piston. Working areas of the first and second piston ends are substantially equal to each other.

摘要： A reflector reflects electromagnetic waves, which waves are emitted into a conducting structure from at least one antenna situated at a distance (d′) from the reflector. The distance (d′) is calculated based on measured emitted and reflected waves to and from the reflector, respectively. The reflector includes a reflector disc, an elongated body having a first longitudinal end and a second longitudinal end, the first longitudinal end being fastened to the reflector disc and the second longitudinal end being fastenable to an accumulator piston. Said elongated body further comprises at least two telescopically interconnected reflector tubes rendering reversible adjustment of the elongated body's longitudinal length around a predetermined equilibrium length possible. A piston accumulator applying the reflector, and a method for measuring the distance (d′) are also provided.
