Integrated injection system

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.

A subsea system comprising:

• a first integrated injection system comprising:
• a first master valve module comprising a first valve and configured to directly fluidly couple to a first wellhead of the subsea system;
• a first in-line-tee (ILT) module configured to directly fluidly couple the first integrated injection system to a flowline of the subsea system via a first t-connection, wherein the flowline is fluidly coupled to a surface platform of the subsea system;
• a first bridge module configured to fluidly couple the first master valve module and the first ILT module and to be removably mounted between the first master valve module and the first ILT module such that first components of the first bridge module are removeable as a first assembly;
• and
• a first common foundation disposed around the first wellhead and extending radially outward from the first wellhead, wherein the first master valve module, the first ILT module, and the first bridge module are disposed at a first plurality of positions on the first common foundation;
• and
• a second integrated injection system comprising:
• a second master valve module comprising a second valve and configured to directly fluidly couple to a second wellhead of the subsea system;
• a second ILT module configured to directly fluidly couple the second integrated injection system to the flowline of the subsea system via a second t-connection, wherein the first integrated injection system and the second integrated injection system are fluidly coupled along the flowline in series via the first t-connection and the second t-connection;
• a second bridge module configured to fluidly couple the second master valve module and the second ILT module and to be removably mounted between the second master valve module and the second ILT module such that second components of the second bridge module are removeable as a second assembly;
• and
• a second common foundation disposed around the second wellhead and extending radially outward from the second wellhead, wherein the second master valve module, the second ILT module, and the second bridge module are disposed at a second plurality of positions on the second common foundation.
