Over-pressure protection system

An over-pressure protection system comprising:

• a main body comprising a main body housing, the main body housing defining a main body chamber;
• an incompressible fluid received in the main body chamber, the incompressible fluid defining a fluid pressure;
• a pressure sensor configured to measure fluid pressure of the incompressible fluid;
• a first barrier comprising a barrier housing and a seal, the barrier housing defining a barrier chamber, the seal received in the barrier chamber, the seal configured to move between a first seal position, wherein the barrier chamber is sealed, and a second seal position, wherein the barrier chamber is unsealed;
• and
• a second barrier positioned in the main body chamber, the second barrier comprising a sealing surface, the sealing surface configured to move between a first sealing surface position and a second sealing surface position.

A method for operating an over-pressure protection system, the method comprising:

• coupling the over-pressure protection system to a pipeline, the pipeline defining a pipeline pressure, the over-pressure protection system comprising a main body housing, the main body housing defining a main body chamber, an incompressible fluid received in the main body chamber;
• transmitting the pipeline pressure to the incompressible fluid;
• measuring a fluid pressure of the incompressible fluid with a pressure sensor of the over-pressure protection system;
• reconfiguring the over-pressure protection system from an under-pressure configuration to an over-pressure configuration at a threshold pressure of the incompressible fluid;
• and
• deactivating the pressure sensor in the over-pressure configuration.
