Abstract: Systems and methods are provided for determining, at an operator executed on a server that is separate from an application, whether to perform an update of the application. The operator may perform an upgrade precheck when it is determined that the update to the application is to be performed. The precheck may include determining whether a database migration is to be performed as part of the update to the application, and receiving an update mode and an update type to determine the upgrade to the application. The operator may provide to the application via an application program interface (API), one or more application shutdown configuration parameters for the update based on the received update mode and update type of the upgrade precheck. The operator may deploy the update to the application based on the determined update mode and update type.

Abstract: A top drive for a drill string, and an apparatus and method for calibrating the top drive. The top drive includes a rotationally driven shaft that is rotatably mounted by a bearing arrangement having at least one axial bearing and at least one load measuring cell for measuring an axial load of the at least one axial bearing. A calibration device including a pressure element is placed at an upper end portion of the drive shaft. The pressure element exerts a defined calibration force onto the drive shaft in an axial direction. The at least one load measuring cell measures the axial load and transmits a measured load value to a comparing unit, which compares the measured load value with the defined calibration force to determine a differential value. The differential value is then used to calibrate the at least one load measuring cell.
