Vertical isolation and flow tree systems and methods

A system to convert a subsea Christmas tree (XT), comprising:

• a sleeve extending into a bore of XT configured to block an XT production flow path;
• a bridging module coupled to an inlet flow path of a flow control module (FCM), wherein the sleeve is configured to block a XT flow path associated with the XT production flow path and to direct a new flow path, associated with a valve assembly, into the FCM;
• and
• an adapter assembly coupled to a subsea control module (SCM), wherein the adapter assembly is configured to reroute one or more support systems for the XT to the valve assembly.

A subsea system, comprising:

• a Christmas tree (XT);
• a completion extending into a wellbore associated with the XT;
• a processing apparatus having an apparatus inlet and an apparatus outlet;
• and
• a vertical inline flow tree (VIFT) system, comprising:
• a closure in a flow path of the XT;
• a valve assembly fluidly connected to an outlet of the XT;
• and
• a bridging module having a first inlet, a first outlet, a second inlet, and a second outlet;
• wherein the first inlet is fluidly coupled to a flow outlet of the valve assembly, the first outlet is fluidly coupled to the apparatus inlet, the second inlet is fluidly coupled to the apparatus outlet, and the second outlet is fluidly coupled to a production flow line.
