| 41 | Seabottom landing base | JP18583389 | 1989-07-18 | JPH0270886A | 1990-03-09 | UIRIAMU EI ABUREO JIYUNIAA |
| PURPOSE: To facilitate collection and reinstallation by releasing a seat ring from a housing support position by moving in the opposite direction, after making the seat ring at the housing supporting position by pushing it in the inward direction by cutting it in by cam work. CONSTITUTION: A guide base 10 is assembled normally on the sea, engaged with a well housing 62 and lowered by a proper string or other equipment, and thereby, the housing 62 is set in the inside of a well bore as its outside downward seating shoulder part 68 is supported on a cut-in seat ring 26. In the meantime, a working ring 28 is at a lower position, engaged with the ring 26 and this ring 26 is held at a housing support position in the radial and inward direction. Additionally, a latch pin 46 is screwed forward in the inward direction, passes through a vertical slot 29 of the working ring 28 and extends out, and the landing base 10 and the housing 62 are firmly connected to each other. Thereafter, when the base 10 is collected, a lining tool 78 is connected to a lining string 80, and when the string 80 is lifted up, the base 10 is lifted up together with it and separated from the housing 62 and collected at the sea. | ||||||

| 54 | METHOD AND APPARATUS FOR DRILLING MULTIPLE SUBSEA WELLS FROM AN OFFSHORE PLATFORM AT A SINGLE SITE | EP12844498.1 | 2012-10-05 | EP2769045A1 | 2014-08-27 | JORDAN, Travis, Randall; KIPP, Robert, M, |
| A floating, offshore drilling and/or production platform is equipped with a rail- mounted transport system that can be positioned at a plurality of selected positions over the well bay of the vessel. The transport system can move a drilling riser with a drilling riser tensioner system and a blowout preventer from one drilling location to another without removing them from the well bay of the vessel. Using the transport system, the drilling riser is lifted just clear of a first well head and positioned over an adjacent, second well head using guidelines. The transport system may then move the upper end of the drilling riser (together with its attached tensioner and BOP) to a second drilling location. A dummy wellhead may be provided on the seafloor in order to secure the lower end of the drilling riser without removing it from the sea while production risers are being installed. | ||||||
| 55 | GUIDE POST | EP11832814.5 | 2011-10-11 | EP2627863A1 | 2013-08-21 | PETTERSEN, Espen |
| A guide post (1) for use in the final part of a guided lowering of equipment (20) toward a predetermined point, or location (30), on the seabed, is described. The guide post (1) is continued, or extended, in a guide wire running towards a structure on the sea surface. A joint (3) is introduced between the very guide post (4) and a fixation foot (2), which foot is designed for fixed attachment to a subsea construction. The joint (3) is able to transfer axially acting forces simultaneously with suspending, or annulling, bending moments. | ||||||

| A floating platform system supports one or more decks (14) above the water surface for accommodating equipment to process oil, gas and water recovered from a subsea hydrocarbon formation. The platform is secured to the seabed by one or more tendoms (17). A central column (12) of the platform includes a moonpool (19) extending axially through the central column (12). The moonpool (19) is open at the lower and upper ends thereof. Riser lateral restraint members (32) are supported within the moonpool (19) for laterally restraining risers (16) disposed in the moonpool (19) and minimizing riser spacing and riser deflection. | ||||||
| 58 | ANCHORING MECHANISM FOR A GUIDE POST | EP98960112.5 | 1998-12-08 | EP1038089A1 | 2000-09-27 | PAL, Bakke |
| An anchoring mechanism for a guide post (1) often used on seabed frames. Normally four replaceable posts (1) are mounted on the seabed frame at certain intervals. From the top of the posts (1) a wire (3) is leading to the surface. By means of the wires (3) equipment can be lowered down to the seabed frames. By means of the present invention an anchoring mechanism is provided which is of a simpler construction and can thus be produced at lower costs. The anchoring mechanism comprises a sleeve formed guide post lock (5) which is movable inside the guide post (1) and which can lock the guide post (1) to the funnel (2) of the seabed frame by means of lower lockpins (7) passing through lower, radial bores in the guide post (1). By means of an anchor lock (4) for the wire (3) the guide post lock (5) can first be raised somewhat enabling the lockpins (7) to be moved radially inwards. The anchor lock (4) is now also able to raise the guide post (1) via upper lockpins (6) in axial slots (8) in the guide post lock (5) passing through upper, radial bores in the guide post (1), in that the lower lockpins (7) are pressed inwardly by means of the lower bevelled edge of the funnel (2). | ||||||

A system and method for attaching and removing equipment (25) from a subsea wellhead (26) in which equipment is lowered and raised on a flexible riser pipe (22), cables (34) extend from the equipment (25) to the wellhead (26) and are winched in and out to control movement of the equipment (25) adjacent the wellhead (26). While the cables (34) are being winched in or out, the cables (34) are maintained in tension by the reel (33) and a motion compensator (36) between the equipment (25) and riser pipe (22) which can reciprocate vertically with the vessel (20) in response to wave action, while the equipment (25) is insulated from this action during engagement and disengagement with the wellhead (26). The cable winch system may be used to reconnect the riser pipe lower connector (29, 31) to the remainder of the equipment (28) after disconnection. |
