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 new jacket installation method is disclosed, especially for shallow water heavy jacket installation applications. The method utilizes a special type of air bags, called launching air bags, to provide low cost net buoyancy in order to make a shallow water jacket self afloat with a sufficient bottom clearance with seabed. At a floating state a minimum size installation crane vessel could be used to perform all needed jacket installation operations such as lowering, setting-down to seabed, driving foundation piles, grouting and the welding between foundation piles and jacket leg tops. For a shallow water heavy jacket installation, a crane vessel cost usually represents a majority cost of a jacket installation. Therefore, a significant savings could be achieved if a minimum size crane vessel could be used, instead of a large size crane vessel. 1.

Method of construction, installation, and deployment of an offshore wind turbine on a concrete tension leg platform

Номер: US20150104259A1
Автор: Fontain M. Johnson
Принадлежит: Individual

Method for construction, deployment, and installation of a wind turbine generator on a floating slip formed concrete tension leg platform/spar (WTG foundation) using gravity anchors. A concrete WTG foundation is built with the ‘slip form’ method, a combination construction/deployment dry dock barge (barge) utilizing wing walls for stability allowing the WTG and WTG foundation to be delivered to the installation site as a complete unit. A split hull hydraulic dump scow facilitates the slip form construction and deployment of the slip-formed gravity anchor(s). The barge is sunk as a dry dock to a draft that permits the WTG/WTG foundation to be floated off. The free floating WTG foundation is ballasted with sea water to its operating draft with 5 feet of freeboard. The tension legs from the gravity anchors are attached to the WTG foundation and snugged with equal tension. The sea water is then removed from the WTG foundation. This process tightens the tension legs to their design loads. The WTG/WTG foundation maintains a relatively large water plane and a 5 foot freeboard. The gravity anchor(s) is constructed from slip formed concrete on a split hull hydraulic dump scow and deployed to the installation site, with tension legs attached for deployment and attachment to the WTG platform.

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 to provide a cut at a selected elevation;b) attaching a plurality of hydraulic rams to the leg sections with a first padeye having a first height, each ram having a hollowed cylinder and an extensible push rod and first and second ram end portions, the rams being attached to the leg section at the ram end portions, one ram end portion being attached to the leg section above the cut and the other ram 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” and “b” for the other leg sections of the platform;d) elevating the platform a first distance by extending each ram to the extended position;e) retracting the ram of step “d”;f) removing the first padeye for the ram of step “d” ram;g) attaching the ram of step “d” to a second padeye having a second height that is greater than the first height; andh) elevating the platform an additional, second distance.2.

An offshore support structure comprising:at least one upper support structure section for supporting at least one functional device with a functional mass;at least one lower support structure section for founding the offshore support structure at a seabed of a sea; andat least one transition support structure section which is arranged between the at least one upper support structure section and the at least one lower support structure section for physically connecting the at least one upper support structures section and the at least one lower support structure section.wherein the at least one upper support structure section, the at least one functional device and the at least one transition support structure section comprise together an upper support structure mass, and the at least one lower support structure section comprises a lower support structure mass,wherein a mass ratio of the lower support structure mass to the upper support structure mass is in a range from 1 to 2.2. The offshore support structure according to claim 1 , wherein the mass ratio is within a ...
