  • Patent number: 10708869
    Abstract: An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.

The termination head allows a subsea cable, a power cable, a power umbilical or an umbilical, to be connected to the subsea structure before lowering them as a unit from a vessel and into the sea. The termination head assembly and subsea structure are to be lowered together while concurrently paying out the cable all the way to the seabed. The termination head is arranged to be hingedly connected relative to the subsea structure, which allows the termination head to pivot about a pivot axis in order to let the subsea cable adopt a natural catenary curvature in the sea during lowering thereof. The cable extends in a pigtail loop from the termination head and into the subsea structure. The pigtail loop is able to perform a “rolling motion” during such pivotal movement of the termination head.

  • Patent number: 9027649
    Abstract: What is provided is a method and apparatus wherein a swivel can be detachably connected to an annular blowout preventer thereby separating the drilling fluid or mud into upper and lower sections and allowing the fluid to be displaced in two stages, such as while the drill string is being rotated and/or reciprocated. In one embodiment the sleeve or housing can be rotatably and sealably connected to a mandrel. The swivel can be incorporated into a drill or well string and enabling string sections both above and below the sleeve to be rotated in relation to the sleeve. In one embodiment the drill or well string does not move in a longitudinal direction relative to the swivel. In one embodiment, the drill or well string does move longitudinally relative to the sleeve or housing of the swivel.

  • Patent number: 9022122
    Abstract: A cap for protecting a sealing surface of a hub of a subsea device includes an equalization valve and a fluid conduit. The equalization valve includes a valve body having a pressure equalization conduit, a sleeve disposed about the valve body and having a port allowing fluid communication across the sleeve, and a valve spring configured to bias the sleeve to a closed position. The sleeve is configured to move to an open position in response to a force that depresses the sleeve and causes the valve spring to compress and the port is fluidly isolated from the pressure equalization conduit in the closed position and is in fluid communication with the pressure equalization conduit in the open position. In the open position, an interior environment of the subsea device is in fluid communication with the environment outside the cap through the equalization valve.

  • 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.
