Abstract: The invention provides a jumper termination apparatus for a subsea jumper flowline, a flow system incorporating a jumper termination apparatus, and a method of use. The jumper termination apparatus comprises a body, a jumper coupling means configured to couple the body to a jumper flowline, a connector coupling means configured to couple the body to a subsea manifold connector, and an access interface disposed on the body, arranged above the connector coupling means and vertically oriented to enable access from above. The body defines a first flow path from a coupled jumper flowline to a coupled subsea manifold connector, and a second flow path from the access interface to the first flow path or the subsea manifold connector. The access interface is configured to be connected to a termination apparatus of a second jumper flowline in a vertically stacked arrangement.

Abstract: The invention provides a subsea manifold for a subsea production system comprising at least one removable module, and methods of installation and use. The at least one removable is configured to perform a function selected from the group comprising: fluid control, fluid sampling, fluid diversion, fluid recovery, fluid injection, fluid circulation, fluid measurement and/or fluid metering.

Abstract: An apparatus and system for accessing a flow system (such as a subsea tree) in a subsea oil and gas production system, and method of use. The apparatus comprises a body defining a conduit therethrough and a first connector for connecting the body to the flow system. A second connector is configured for connecting the body to an intervention apparatus, such as an injection or sampling equipment. In use, the conduit provides an intervention path from the intervention apparatus to the flow system. Aspects of the invention relate to combined injection and sampling units, and have particular application to well scale squeeze operations.

Abstract: The invention provides an apparatus for introducing a fluid into a subsea production flow system, a system and a method of use. The apparatus comprises a first flow path through the apparatus for fluidly coupling a subsea well to a subsea production flow system and an inlet for receiving a fluid. A second flow path fluidly connects the inlet and the subsea production flow system. A valve is operable to control the flow of the fluid through the inlet to the subsea production flow system. In one embodiment, the invention provides an apparatus for preventing or reducing flow of a first treatment chemical into a subsea production flow system, a system, and a method of use. In an alternative embodiment, the invention provides an apparatus for injecting a gas into a subsea production flow system, a system, and a method of use.

Abstract: The invention provides an apparatus and system for accessing a flow system (such as a subsea tree) in a subsea oil and gas production installation, and method of use. The apparatus comprises a body and a plurality of connectors configured to connect the apparatus to the flow system. A flow access interface is provided on the body for connecting the apparatus to a subsea process apparatus, and the body defines a plurality of flow paths. Each flow path fluidly connects one of the plurality of connectors to the flow access interface to provide an intervention path from a connected subsea process apparatus to the flow system in use. Aspects of the invention have particular application to flow metering, fluid sampling, and well scale squeeze operations.

Abstract: A valve apparatus (400) for a flow system in a subsea oil and gas production installation and a method of use. The valve apparatus comprises an inlet for production flow from the subsea oil and gas production installation, an outlet for production flow, and a flow control valve (420) disposed between the inlet and the outlet. A first flow line (361) in communication with a sampling circuit is disposed between the inlet and the flow control valve, and a second flow line (362) in communication with a sampling circuit is disposed between the outlet and the flow control valve. The flow control valve is operable to be partially closed to create a pressure differential between the first and second flow lines, and thereby drive a production fluid into the sampling circuit.

Abstract: The invention provides a sampling apparatus for sampling fluid from a pipeline system during a pigging operation and a method of use. The sampling apparatus comprises an inlet configured to be coupled to the pipeline system, for receiving a fluid carried by a pigging operation from the pipeline system, and an outlet for discharging fluid from the sampling apparatus. A flow control valve is disposed between the inlet and the outlet. A first flow line is in communication with a sampling circuit and is disposed between the inlet and the flow control valve. A second flow line is in communication with a sampling circuit, and is disposed between the outlet and the flow control valve. The flow control valve is operable to be partially closed to create a pressure differential between the first and second flow lines, and drive a fluid passing through the sampling apparatus into the sampling circuit.
