  • Loose wheel detection
    Patent number: 12151655
    Abstract: The disclosed invention makes use of a wheel speed signal to detect a wheel anomaly such as a loose wheel or a wheel with zero pressure. The wheel speed signal is used as a basis to determine a first and a second detection signal. A further basis for determining the first and second detection signals are a first and second reference signal, respectively. The anomaly of e.g. a loose wheel is detected, according to the teaching of the invention if at least one of the detection signals exceeds a threshold. In particular, the disclosure relates to methods, systems and computer program products to achieve the mentioned objective.

  • Wellhead system
    Patent number: 12037863
    Abstract: A wellhead system includes a wellhead assembly which is generally tubular, a landing string assembly, and an orientation sensor assembly which is mounted on the landing string assembly. The wellhead assembly is secured to a top of a borehole and has an orientation engagement part. The landing string assembly is lowered into the wellhead assembly to land in the wellhead assembly. The landing string assembly has an orientation part with an orientation feature. The orientation engagement part of the wellhead assembly corresponds to the orientation feature. As the landing string assembly is lowered into the wellhead assembly, the orientation feature engages with the orientation engagement part to rotate the landing string assembly about its longitudinal axis into a desired orientation relative to the wellhead assembly. The orientation sensor assembly measures an angular rotation of the landing string assembly about its longitudinal axis.
