A process for installing the payload onto a subsea structure has the steps of affixing an adapter spool on to the subsea structure, deploying a plurality of winches in spaced relation to the subsea structure, connecting an end of a plurality of slings received on the plurality of sheaves to a plurality of winches, connecting an opposite end of the plurality of slings to the payload, lowering the payload in a direction toward the subsea structure, actuating the plurality of winches so as to draw the payload downwardly into a position on the subsea structure, and locking the payload onto the subsea structure. The adapter spool has a collar with a plurality of sheaves extending outwardly therefrom. The payload can be a capping stack and the subsea structure can be a blowout preventer.

Process and apparatus for installing a payload onto a subsea structure

A process for installing or removing a subsea structure in a non-vertical manner at a well includes securing a plurality of barges together in a linear formation in which one of the plurality of barges has a downline extending therefrom, connecting an end of the barges to a primary vessel, moving the primary vessel such that one of the barges is positioned over a target at or adjacent to the well, connecting a plurality of secondary vessels by plurality of mooring lines to an opposite end of the barges, tensioning the mooring line so as to fix the opposite end of the barges, positioning a deployment vessel away from the barges, deploying an ROV, manipulating the ROV so as to connect the subsea structure to the downline, and moving the downline and the subsea structure toward or away from the well.

Process for non-vertical installation and removal of a subsea structure

A method and apparatus for transporting a capping stack for use in a subsea structure includes a capping stack having a capping stack spool, a connector body connectable to the capping stack spool and at least one diverter leg connectable to the capping stack spool. A first skid receives the capping stack spool on a floor thereof. A second skid receives the connector body on a floor thereof. A third skid receives the diverter leg thereon. The first, second and third skids are adapted to be received within an interior of an aircraft. The skids and the connected components can then be flown by the aircraft to a desired location so as to be assembled at a location near a wellhead.

A process for killing a well includes drilling a first relief well and a second relief well toward the well, affixing a first relief well injection spool to the first relief well and affixing a second relief well injection spool to the second relief well, connecting a flowline to a flow channel of the first and second relief well injection spools, connecting a pipe to the first relief well injection spool so as to extend to a surface location, connecting a second pipe to the second relief well injection spool so as to extend to another surface location, and flowing a kill fluid through the second pipe such that the kill fluid flows through the flowline and into the flow channel of the first relief well injection spool so as to pass into the first relief well and into the well.

Process and system for killing a well through the use of relief well injection spools

A relief well injection spool for use in killing a well has a body with a pair of inlets opening to a bore on an interior of the body, a ram body cooperative with the bore of the body so as to selectively open and close the bore, an upper connector affixed to the body and adapted to connect the body to a lower end of a blowout preventer, and a wellhead connector affixed to a lower end of the body. Each of the pair of inlets has a valve cooperative therewith. The upper connector opens to the bore of the body. The wellhead connector is adapted to connect to a relief well wellhead. The wellhead connector also opens to the bore of the body. A floating vessel can be provided so as to deliver a kill fluid into at least one of the pair of inlets.

Relief well injection spool apparatus and method for killing a blowing well

A sensing system for use with a subsea actuator has an actuator with a cylinder having a piston therein, and a piston rod extending outwardly of the cylinder, a magnetic member connected to or cooperative with an end of the piston rod, and a magnetic field sensor positioned over the magnetic member so as to sense magnetic field changes in relation to a movement of the magnetic member relative to the magnetic field sensor. A data acquisition system is cooperative with the magnetic field sensor for receiving a signal from the magnetic field sensor. A housing is positioned over the magnetic field sensor and over the magnetic member. The magnetic member moves through the housing in relation to a movement of the piston rod.
