Patent GB-2182083-A (GB)
Title: Method of conducting well operations from an offshore platform
Inventor: SELLARS JR CLAUDE ALEXANDER
IPC: E21B7/128
Filed: 1986-10-22
Abstract: A method is described for conducting well operations from a floating platform 11 that may be moved to various locations above subterranean formations. Marine risers 30,33 that have been previously connected to the platform flex sufficiently to allow this movement. The mobility of the platform allows well drilling, completion, producing, and workover activities to be conducted simultaneously through the risers attached to the platform. The mobility of the platform also allows new wells to be drilled at more preferable locations than those that would be available from a fixed bottom supported well template. <IMAGE>

Title: Improved lifting arrangement
Inventor: O'REILLY RORY
IPC: F15B11/22
Filed: 1991-02-07
Abstract: In order to achieve simultaneous and constant raising of a roof, e.g. a vehicle roof at all corners or edges (in order to prevent warping) at least two, preferably four, hydraulic jacks 10, 20, 30, 40 each including a slideably piston rod 12, 22, 32 42, linked together to form a "closed system". One connecting tube 54 passes through a pump 50 which can be operated to displace fluid within the system. When the pump 50 is actuated fluid will be supplied to a first jack 10 causing a displacement of the piston 12. This displacement forces fluid out of the first jack 10 and into the second jack 20 causing a corresponding piston displacement. Thus the third and fourth jacks 30, 40 are also subject to piston displacement by movement of the fluid. <IMAGE>
