Abstract: A system, including one or more supports disposed on a drill floor. The system also includes a movable support slidingly coupled to the one or more supports and configured to be selectively moved towards the drill floor during a tripping-in operation as part of a continuous tripping operation and away from the drill floor during a tripping-in operation as part of a continuous tripping operation, and a tripping apparatus coupled to the movable support and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment, wherein the tripping apparatus is configured to be selectively movable from a first position disposed proximate to the one or more supports and a second position at a distance away from the one or more supports to make up the threaded joint when the tripping apparatus is disposed in the second position during the tripping-in operation or to break out the threaded joint when the tripping apparatus is disposed in the second position during the tripping-out operation.

Abstract: A system, including one or more supports. The system also includes a movable platform slidingly coupled to the one or more supports and configured to be selectively moved towards a drill floor and away from the drill floor. The system further includes a roughneck disposed on the movable platform and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment, wherein the roughneck is configured to be selectively movable along the movable platform from a first position disposed adjacent to the one or more supports and a second position disposed adjacent to the first tubular segment and the second tubular segment.

Abstract: Techniques and methods to reduce downtime in an offshore platform, such as an offshore semi-submersible drilling rig or drillship. Through the use of one or more movable platforms in a moon pool area, work on a riser string passing through the moon pool area may be performed without exposing workers directly to the open sea below. Accordingly, the use of the one or more movable platforms in the moon pool area may provide protected access to the riser string during, for example, harsh weather conditions.
Abstract translation: 减少海上平台的停机时间的技术和方法，如海上半潜式钻井平台或钻井平台。 通过在月球池区域中使用一个或多个可移动平台，可以在穿过月球池区域的提升管线上进行工作，而不会将工人直接暴露在下面的公海之外。 因此，在例如恶劣的天气条件下，在月球池区域中使用一个或多个可移动平台可以提供对提升管柱的受保护的通路。

Abstract: Techniques and systems to couple a high pressure casing string to a blowout preventer or a subsea shut-in device. A device includes a locking mechanism configured to interface with a terminal end of a casing string of an offshore platform to couple the device to the terminal end of the casing string. The device also includes a sealing mechanism configured to fluidly seal an area around the terminal end of the casing string, wherein the locking mechanism and the sealing mechanism are disposed at separate positions along a vertical orientation of the device.
