    Abstract: A template for use in positioning subsea wellbores that has a drop away funnel that extends laterally from the template. The drop away funnel is used to locate a piling adjacent the wellbores and is selectively detached from the template after installing the piling. A tang and clevis type assembly mounts the drop away funnel to the template, where the tang and clevis are coupled together with a main stud. The main stud is oriented substantially parallel with an axis of the drop away funnel; so that when the stud is removed, the drop away funnel can decouple from the template and slide axially downward along the piling.

  • Patent number: 7905298
    Abstract: Disclosed are systems and methods for drilling in an environment having a fluid and a bed. The method includes positioning a platform such that the fluid is between the platform and the bed; and assembling a guide, the assembled guide being straight. The method subsequently acts to place the guide such that the guide is supported by the platform, and a major length of the guide and a normal to the bed defines an angle, the angle being substantially greater than 0. Thus, the positioned guide allows for sending a variable angle drill inside the guide, from the platform into the bed.

  • Publication number: 20030159853
    Abstract: An offshore drilling rig contains a heavy-duty support cart that straddles the moonpool and rides on rails. A funnel-shaped hole extends through the support cart, and a cutout on one side of the cart provides lateral access to the hole. The cart can be moved to the region of the rotary assembly, where a length of tubulars can be suspended from the cart. For instance, when the BOP is pulled out for installation of the Xmas tree assembly, the BOP and attached riser can be pulled up above the seabed and hung from the support cart, then moved laterally out of the way while the Xmas tree assembly is installed. This lateral movement lowers the possibility of collision between the BOP and Xmas tree assembly. The BOP assembly can then be disassembled and at a later time, or hung until is needed for an adjacent borehole. In a preferred embodiment, the cart is included on multi-activity rigs with more than one load path, hoist, and rotary assembly.

    Abstract: A process and an apparatus for sinking drill holes, in particular exploration and extraction drill holes, with a drill pipe, which at its end facing the floor to be mined is provided with a guide point fixed in the longitudinal direction of the drill pipe and a drill head with at least one cutting element. The drill head can be moved in the longitudinal direction of the drill pipe between a top position, in which the guide point projects beyond the at least one cutting element, and a bottom position in which the at least one cutting element is positioned at the same height as the end of the guide point or projects beyond same in the operating direction. When the drill head is in the top position, the drill pipe is moved in the direction of the drill hole to be produced until the guide point by cooperating with the floor fixes it in position. Then the drill head is moved into its bottom position in order to produce the drill hole.

    Abstract: A method for mounting a seabed installation including a drilling template and a manifold on a mooring device anchored to the seabed. The mooring device comprises an open guide boring. The drilling template and the manifold are arranged to be suspended separately on, and lowered by a string which extends from an offshore platform. The method includes lowering the manifold and inserting a connected guide post which projects down from the manifold, in a guide hole of the drilling template. Thereafter, interacting sections of the central guide post and the guide hole respectively are made to cause an alignment of the manifold in a fixed rotational position relative to the drilling template during the introduction and before the manifold comes into contact with the drilling template. Finally, the manifold is lowered relative to the guide post after the contact thereof in the guide hole. No use is made of guidelines which extend from the platform to the seabed.

  • Patent number: 6129487
    Abstract: A tool is provided for use in submerged condition for installing anchor or foundation elements such as piles in a ground formation that is submerged under a body of water. A hammer body is fixedly supported in axial alignment with the head of a pile that is to be driven and carries a reaction body guided for movement thereon in a direction that is axial to the pile. The hammer body and reaction body define opposed first and second ends of an expansion chamber. A pyrotechnic charge is initiated to create a rapidly expanding volume of high pressure gas in the expansion chamber to generate a downwards pressure force pulse to drive the pile, an equal and opposite upwards pressure force pulse being applied to the reaction body. Damping structure operatively associated with the reaction body interacts with the water in which the tool is submerged using the inertia of the water to resist upwards movement of reaction body.
