摘要： The invention provides an access apparatus for accessing a flow system in a subsea oil and gas production installation, a method of installation and a subsea horizontal connection installation. In one aspect, the access apparatus comprises a body, a plurality of connectors configured to connect the apparatus to the flow system and an access interface providing an access point to the flow system. The body defines at least one bore which fluidly connects at least one of the plurality of connectors to the access interface to provide a path between the access interface and the flow system. A first connector of the plurality of connectors is oriented with a longitudinal axis in a substantially horizontal plane, such that the at least one connector is configured to connect to a respective horizontally oriented connector of the flow system and a second connector of the plurality of connectors forms part of a connection interface for a jumper flowline, the connection interface replicating a flow system connection interface. The access apparatus is configured to be connected between the, flow system connection interface and the jumper flowline.

摘要： The invention provides a jumper termination apparatus for a subsea jumper flowline, a flow system for a subsea hydrocarbon production or injection installation incorporating such 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, and a connector coupling means configured to couple the body to a subsea manifold connector. An access interface is disposed on the body. 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 second jumper flowline. A flow system comprises a subsea manifold and a first jumper flowline having a first jumper termination apparatus connected to a first subsea manifold connector, and may also comprise a second jumper flowline having a second jumper termination apparatus, wherein the second jumper flowline is connected to the subsea manifold via the first access interface and the subsea manifold connector.

摘要： The invention provides a subsea oil and gas production installation, methods of installing the installation and methods of use. The installation comprises a subsea production system comprising a first production pipeline and a second production pipeline, a first subsea manifold in fluid communication with the first production pipeline comprising a fluid access interface and a flowline connector, a removable module fluidly connected to the fluid access interface of the first subsea manifold and configured to receive production fluid from one or more subsea wells and a second subsea manifold in fluid communication with the second production pipeline. The first subsea manifold defines a first flow path between the fluid access interface and the first production pipeline and a second bypass flow path between the fluid access interface and the flowline connector. The first and the second subsea manifolds are fluidly coupled to one another by a connecting flowline which is connected at a first end to the flowline connector of the first subsea manifold. The removable module comprises a flow control means operable to selectively route the production fluid from one or more subsea wells into the first production pipeline via the first flow path defined by the manifold, and/or into the second production pipeline via the second bypass flow path, the connecting flowline and the second subsea manifold.

摘要： 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.
