Abstract

An integrated injection system of a subsea system may include a master valve module having at least one valve and an in-line-tee (ILT) module. The master valve module may directly fluidly couple to a wellhead of the subsea system, and the ILT module may directly fluidly couple the integrated injection system to a flowline of the subsea system via a t-connection. Additionally, the integrated injection system may include a bridge module that fluidly couples the master valve module and the ILT module and is removably mounted between the master valve module and the ILT module such that components of the bridge module are removeable as an assembly. Furthermore, a common foundation may support each of the master valve module, the ILT module, and the bridge module.

First claim

What is claimed is:

1 . An integrated injection system of a subsea system, the integrated injection system comprising:
a master valve module comprising at least one valve and configured to directly fluidly couple to a wellhead of the subsea system; an in-line-tee (ILT) module configured to directly fluidly couple the integrated injection system to a flowline of the subsea system via a t-connection; a bridge module configured to fluidly couple the master valve module and the ILT module and to be removably mounted between the master valve module and the ILT module such that components of the bridge module are removeable as an assembly; and a common foundation extending radially outward from the wellhead of the subsea system, wherein the master valve module, the ILT module, and the bridge module are disposed at a plurality of positions on the common foundation.

2 . The integrated injection system of claim 1 , comprising a communication module mounted to the common foundation and configured to receive control signals from a surface platform and to control actuation of the at least one valve based on the control signals.

3 . The integrated injection system of claim 1 , wherein the bridge module comprises a choke valve configured to regulate a flow of fluid between the master valve module and the ILT module.

4 . The integrated injection system of claim 3 , wherein the components of the bridge module comprise a plurality of sensors configured to monitor the flow of the fluid.

5 . The integrated injection system of claim 3 , wherein the components of the bridge module comprise power generation equipment.

6 . The integrated injection system of claim 1 , wherein the master valve module comprises a vertical monobore, relative to the wellhead, and wherein the bridge module is configured to directly couple to a vertical top of the master valve module.

7 . The integrated injection system of claim 6 , wherein the bridge module is configured to vertically mount to the ILT module.

8 . The integrated injection system of claim 6 , wherein the at least one valve comprises an isolation valve configured to selectively fluidly isolate the wellhead from the bridge module.

9 . The integrated injection system of claim 1 , wherein the ILT module comprises one or more valves configured to selectively fluidly isolate the integrated injection system from other integrated injection systems disposed in series along the flowline.

10 . The integrated injection system of claim 1 , wherein the one or more positions comprise a plurality of different horizontal positions on the common foundation.

11 . The integrated injection system of claim 1 , wherein the master valve module, the ILT module, and the bridge module are horizontally offset from each another.

12 . A method for implementing an integrated injection system in a subsea system, the method comprising:
installing a wellhead of a well at a well site of the subsea system; installing a common foundation at the well site of the subsea system after installing the wellhead at the well site, wherein the common foundation is disposed around the wellhead; mounting a master valve module to the common foundation and the wellhead after installing the common foundation at the well site, the master valve module comprising at least one valve configured to selectively fluidly isolate the integrated injection system from the wellhead, wherein mounting the master valve module comprises fluidly coupling the master valve module and the wellhead; mounting an in-line-tee (ILT) module to the common foundation, the ILT module comprising one or more valves, wherein the ILT module is configured to fluidly couple the integrated injection system to a flowline of the subsea system; and directly coupling a bridge module to the master valve module and the ILT module after mounting the master valve module to the common foundation, the bridge module comprising an assembly of piping and flow control components, wherein the bridge module is configured to fluidly couple the master valve module and the ILT module via the piping.

13 . The method of claim 12 , wherein the flow control components comprise a choke valve configured to regulate a flow of fluid through the piping, wherein the assembly comprises the piping, the flow control components, and one or more sensors configured to monitor the flow of the fluid through the piping, and wherein the assembly is pre-assembled prior to coupling of the bridge module to the master valve module.

14 . The method of claim 12 , comprising mounting a communication module to the common foundation, the communication module configured to communicate signals with a surface platform of the subsea system and to control operation of the at least one valve of the master valve module, the one or more valves of the ILT module, and the flow control components of the bridge module based on the communicated signals.

15 . The method of claim 14 , wherein the ILT module, the communication module, or both are mounted to the common foundation prior to installing the common foundation at the well site.

16 . The method of claim 12 , wherein the master valve module is mounted vertically on top of the wellhead, the ILT module is mounted laterally adjacent to the wellhead, and the piping of the bridge module is configured to vertically fluidly couple to the master valve module and vertically fluidly couple to the ILT module.

17 . A subsea system comprising:
