Abstract: A hydraulic cylinder unit for connection to a wire line riser tensioner system includes a hydraulic cylinder comprising a cylinder piston separating a first cylinder chamber from a second cylinder chamber. A low pressure tank is arranged as a closed cylinder. A first conduit is inserted into the closed cylinder and provides a fluid communication between the low pressure tank and the first cylinder chamber. A second conduit provides a fluid communication between a high pressure fluid reservoir and the second cylinder chamber. A feedback conduit provides a fluid communication between the first cylinder chamber and the second cylinder chamber. A valve element comprising at least one valve is configured to be in a fluid communication with the at least one first conduit and the at least one feedback conduit. The valve element is configured to provide a reversible switching between a first alternative configuration and a second alternative configuration.

Abstract: A riser assembly includes a riser with a first and second riser joint, an auxiliary line, and a first and second flange. The auxiliary line has an auxiliary line joint which connects a first and second auxiliary line section. The auxiliary line joint has a first joint assembly connected to the first auxiliary line section, and a second joint assembly connected to the second auxiliary line section. The first and second joint assembly each have a bearing surface. A bearing surface of the first flange engages the bearing surface of the first joint assembly. A bearing surface of the second flange engages the bearing surface of the second joint assembly. The bearing surface of the first flange or of the first joint assembly also has a rocker formation which contacts the bearing surfaces of the first flange and of the first joint assembly while permitting a relative angular movement therebetween.

Abstract: A drilling rig system includes a drilling rig having a floor which is generally planar, and a utility vehicle having a base, a drive apparatus, and a ground engaging motive apparatus upon which the base is supported on the floor. The drive apparatus drives the ground engaging motive apparatus to move the utility vehicle across the floor. The ground engaging motive apparatus is drivable so as to change a direction of travel of the utility vehicle at any point on the floor.

Abstract: A method for analyzing a drilling operation includes obtaining a first set of logged operational data from the drilling operation through a first time interval, obtaining a set of operational activity dividers that delimit second time intervals within the first time interval, allocating one of a plurality of pre-defined activities to each of the second time intervals, wherein a first activity is one of the plurality of pre-defined activities, calculating a first performance indicator parameter for the second time intervals which have been allocated to the first activity, generating a time-dependent profile of the first performance indicator parameter for the second time intervals, and outputting at least one calculated value of the first performance indicator parameter to an operator. The first performance indicator parameter is calculated as a function of a duration of a respective second time interval which has been allocated to the first activity.

Abstract: A wireline tensioner includes at least one sheave, a first accumulator unit, a second accumulator unit, a hydraulic distribution system, and a hydraulic cylinder unit which is operatively connected to the at least one sheave, to the first accumulator unit and to the second accumulator unit via the hydraulic distribution system. The first accumulator unit receives hydraulic fluid from the hydraulic distribution system at a first hydraulic pressure. The second accumulator unit receives the hydraulic fluid from the hydraulic distribution system at a second hydraulic pressure. The first hydraulic pressure is lower than the second hydraulic pressure.
