    Abstract: A drilling vessel with a drilling deck includes a drilling vessel floor structure defining the drilling deck and a tubular support assembly that is recessed in the drilling floor structure. The assembly includes a support frame and at least two support tables, wherein the tables have a top surface that forms part of the drilling deck. The tables are each guided by the support frame to allow displacement along a line between an active position for supporting a tubular and a retracted position for passing an object. The tables and the adapters segments supported thereby are coupled, for example via a clamp or a shape-coupling, such that when the tables move from their active position into their retracted position each segment moves with the respective table it is coupled with and the bushing is opened up for passing through an object through the opening between the at least two support tables and the adapter segments they support.

    Abstract: An offshore universal riser system. A riser system includes a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage. Drilling methods include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, is dimensioned for installation through a rotary table.

  • Patent number: 8978774
    Abstract: A subsea mud pump can be used to return heavy drilling fluid to the surface. In order to provide a less stringent requirement for such a pump and to better manage the bottom hole pressure in the case of a gas kick or well control event, the gas should be separated from the drilling fluid before the drilling fluid enters the subsea mud pump and the pressure within the separating chamber. The mud pump suction should be controlled and kept equal or lower than the ambient seawater pressure. This can be achieved within the cavities of the subsea BOP by a system arrangement and methods explained. This function can be used with or without a drilling riser connecting the subsea BOP to a drilling unit above the body of water.

The shallow water flow monitoring system uses time periods and intervals while mud pumps are turned off. The system uses a video feed, and a processor with data storage containing a discharge category model, and wherein the data storage receives a drilling parameter data feed, a seismic profile data feed, a logging while drilling data feed, and a measurement while drilling data feed, to verify a determined discharge category as a baseline discharge category. The system provides an alarm when a discharge emergency is ascertained due to a change in discharge category without an anticipated change or changes outside acceptable limits.

  • Patent number: 8905156
    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: 8887814
    Abstract: An offshore universal riser system. A riser system includes a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage. Drilling methods include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, is dimensioned for installation through a rotary table.

  • Patent number: 8863858
    Abstract: A system compensates for heave-induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during NIPD, tripping, cementing operations or when a kick is circulated out during conventional drilling. In one embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. The system also compensates for heave induced pressure fluctuations on a floating rig when a riser telescoping joint located below an RCD is moving between its retracted and extended positions while drilling.

  • Publication number: 20140262505
    Abstract: A method and system for lifting drilling mud from subsea to a drilling vessel, which uses a pump having a body with a chamber, and a bladder in the chamber. The bladder attaches to the body and defines water and mud sides in the chamber. A mud inlet valve allows mud into the mud side of the chamber; which moves the bladder into the water side and urges water in the water side from the chamber and through a water exit valve. Pressurized water enters the chamber through a water inlet valve, which in turn pushes the bladder and mud from the chamber through a mud exit valve. The bladder separates the mud and water as it reciprocates in the chamber. The travel of the bladder in the chamber is controlled to prevent damage from contact with the chamber.
