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.
Claims20
A flow access apparatus for a flow system in a subsea oil and gas production installation, the flow access apparatus comprising:
- a body;
- a plurality of connectors configured to connect the flow access apparatus to the flow system;
- and
- a flow access interface for connecting the flow access apparatus to a subsea process apparatus;
- wherein the flow access interface provides a single connection point and/or landing point for the subsea process apparatus;
- wherein the body defines a plurality of flow paths, and 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;
- and
- wherein the flow access apparatus is configured to be disposed between a flow line connector for a jumper flow line and the jumper flow line to provide an access point for the flow system and an access point to the jumper flow line from the connected subsea process apparatus in use.

- and
- wherein the flow access apparatus is disposed between a flow line connector for a jumper flow line and the jumper flow line to provide an access point for the subsea flow system and an access point to the jumper flow line from the connected subsea process apparatus in use.
A method of performing a subsea intervention operation, comprising:
- providing a subsea well and a subsea flow system in communication with the subsea well, the subsea flow system comprising a jumper flow line;
- providing a flow access apparatus on the subsea flow system, the flow access apparatus comprising:
- a body;
- a plurality of connectors, and
- a flow access interface for connecting the flow access apparatus to a subsea process apparatus;
- wherein the flow access interface provides a single connection point and/or landing point for the subsea process apparatus;
- wherein the body defines a plurality of flow paths, and each flow path fluidly connects one of the plurality of connectors to the flow access interface;
- and
- wherein the flow access apparatus is disposed between a flow line connector for a jumper flow line and the jumper flow line to provide an access point for the subsea flow system and an access point to the jumper flow line from a connected subsea process apparatus;
- providing the subsea process apparatus on the flow access interface;
- and
- accessing the subsea flow system via an intervention path formed through one of the plurality of flow paths defined by the body to one of the plurality of connectors.
