Systems and methods for subsea fluid handling

A method of establishing a fluid connection in a subsea petroleum production system, the method comprising:

• positioning a first subsea fluid handling component having a first connector adjacent a second subsea fluid handling component having a second connector, the first and/or second connectors having a breakable plug sealingly arranged therein, wherein the first subsea fluid handling component is a pipe;
• operating an actuator to make up a connection between the first and second connectors while the breakable plug is intact;
• bringing a loading member, which is movably arranged in the pipe into engagement with the breakable plug and effecting a load onto the breakable plug such as to damage the breakable plug, wherein the load is effected onto the breakable plug by the loading member as part of a locking operation which locks the first connector to the second connector;
• and
• shattering the breakable plug such as to open for fluid connection between the first and second subsea fluid handling components, wherein the step of shattering the breakable plug comprises increasing a pressure at a pipe side of the breakable plug so as to cause a shattering of the breakable plug.
