Abstract

Systems, methods, and devices for relieving overpressure associated with thermal expansion of fluid within a closed cavity of a subsea manifold assembly. The subsea manifold assembly may comprise a header bore fluidly connected to one or more branch connections. A unidirectional valve is included at the branch connections to allow fluid leakage from the closed cavity into a header bore of the subsea manifold assembly to thereby reduce a pressure within the cavity while in the closed position.
