Ice worthy jack-up drilling unit with telescoping riser

Номер: US20120125690A1
Автор: Dominique P. Berta, Peter G. Noble, Randall S. Shafer
Принадлежит: ConocoPhillips Co

The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the legs are held in place by cans embedded in the sea floor to resist lateral movement of the rig and the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration.

A method of elevating the deck area of a marine platform (e.g., oil and gas well drilling or production platform) utilizes a specially configured sleeve support to support the platform legs so that they can be cut. Once cut, rams or jacks elevate the platform above the cuts. The sleeve support is then connected (e.g., welded) to the platform leg and becomes part of the structural support for the platform. In one embodiment, two sleeves are employed. In another embodiment, the jacks or rams elevate in two stages including a first stage wherein one sleeve elevates and the other sleeve does not elevate and a second stage wherein both sleeves elevate together. 1. A method of elevating a marine platform that is supported by a plurality of hollow metallic leg sections that extend above and below a water line of a body of water , comprising the steps of;a) cutting one of the leg sections at a selected elevation;b) attaching a plurality of hydraulic rams to the leg sections, each ram having a hollowed cylinder and an extensible push rod and first and second end portions, the rams being attached to the leg section at the end portions, one end portion being attached to the leg section above the cut and the other end portion being attached to the leg section below the cut, and wherein each ram has a retracted and an extended position;c) repeating steps “a” through “b” for the other leg sections of the platform;d) elevating the platform a first distance by extending each ram to the extended position; ande) elevating each ram a second distance.2.

A simplified structure allows inspection of the installation strength of an anchor installed underwater. A method includes applying, to an anchor, a lifting force from above a floating body floating on a water surface to submerge the floating body into water, and setting a volume of submergence by which the floating body is submerged to a value to produce a lifting force corresponding to a predetermined installation strength and determining whether the anchor is immovable. The volume of submergence by which the floating body is submerged to produce the lifting force corresponding to the predetermined installation strength is calculated based on the buoyancy acting on the floating body.
