    • A system for managed pressure drilling, or for workover of a hydrocarbon well with a wellhead, the system comprising a floating structure that is located in a body of water. A method is also described for connecting up the system for managed pressure drilling or well workover. The floating structure comprises a drill floor and a work deck that is movably arranged in an essentially vertical direction in relation to the drill floor. The system further comprises a riser and a slip joint that is connected to the underside of the work floor and to the upper end of the riser such that the work deck can be moved relative to the riser. The riser extends from the slip joint down to a wellhead valve device arranged on the wellhead of the hydrocarbon well. The floating arrangement also comprises heave-compensated riser tensioners which are connected to the slip joint such that the riser is held under tension. The system further comprises a BOP that is arranged on the work deck and a high-pressure riser that is arranged through the riser and the slip joint and is connected to the BOP on the work deck and to the wellhead valve device, thereby forming a continuous high-pressure connection from the work deck down to the hydrocarbon well.
    • 一种用于管理压力钻井或用于修井井与井口的系统,所述系统包括位于水体中的浮动结构。 还描述了一种用于连接管理压力钻井或修井的系统的方法。 浮动结构包括钻台和相对于钻台基本上垂直方向可移动地布置的工作台面。 该系统还包括提升管和滑动接头,其连接到工作地板的下侧和提升管的上端,使得工作台面可以相对于立管移动。 提升管从滑动接头向下延伸到设置在烃井的井口上的井口阀装置。 浮动装置还包括连接到滑动接头的升沉补偿式立管张紧器,使得立管保持张力。 该系统还包括布置在工作台面上的BOP和通过提升管和滑动接头布置的高压提升管,并连接到工作台面上的BOP和井口阀装置,从而形成连续的 从工作台到油气井的高压连接。

    • The invention relates to a transfer device between a first installation (10) and a second installation (20). The transfer device (1) comprises at least one transfer conduit (14), for example for transferring cryogenic fluid or the like, and a universal joint (16), where the transfer device permits relative motion between the first installation and the second installation. The universal joint comprises a first joint device (21) with a bearing that forms a first axis (A); a second joint device (41) with a bearing that forms a second axis (B); a connector (51, 53) rotatably mounted in each of the joint devices (20, 40) about the respective axes of rotation (A, B), so that the first axis of rotation (A) is perpendicular to the second axis of rotation (B); where the transfer conduit (14) is passed through the connector.
    • 本发明涉及一种在第一安装件(10)和第二装置(20)之间的传送装置。 传送装置(1)包括至少一个传送导管(14),例如用于传送低温流体等,以及万向接头(16),其中传送装置允许第一安装和第二安装之间的相对运动。 万向接头包括具有形成第一轴线(A)的轴承的第一接头装置(21); 具有形成第二轴线(B)的轴承的第二接头装置(41); 连接器(51,53)围绕各个旋转轴线(A,B)可旋转地安装在每个接合装置(20,40)中,使得第一旋转轴线(A)垂直于第二旋转轴线 (B); 其中输送管道(14)穿过连接器。
