Abstract: A deep water drilling riser pressure relief system includes a drilling riser extending from a surface down to a BOP stack arranged subsea. The drilling riser comprises a drilling riser slip joint, an annular preventer arranged below the drilling riser slip joint, and at least one pressure relief device arranged in a lower part of the drilling riser. The at least one pressure relief device is configured to open so as to discharge a fluid from the drilling riser to the sea if a pressure difference between an inside and an outside of the drilling riser exceeds a pre-determined threshold.

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 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.

Abstract: A system for controlling a remotely controlled equipment. The system includes an operator station with a main operating device which is operated by an operator to provide a main operating device signal, an operator station controller, and a confirmation operating device which is operated by the operator to provide a confirmation operating device signal. An equipment controller is connected to the operator station controller. A first gate is connected to the equipment controller. The first gate enables an operation of the remotely controlled equipment. A critical action controller receives the confirmation operating device signal. A second gate is connected to the critical action controller. The second gate enables the operation of the remotely controlled equipment.
