A recently granted patent (Publication Number: US11892103B2) discloses a shroud design comprising a cover structure and a plurality of retaining members with unique features. Each retaining member includes an arm coupled to a hinge and a spring, allowing temporary fixation in a position orthogonal to the interior surface of the cover structure. The hinge permits movement in one direction while preventing movement in the opposite direction, enhancing the functionality of the shroud.

Furthermore, the patent details a method for attaching the shroud to a pipeline flange, involving lowering the cover structure to engage the arms with studs on the flange. The arms, equipped with springs providing bias in one direction, move past the studs as the cover structure surrounds the flange. The design includes movable plates associated with each arm, restricting movement in one direction when in a first position but allowing free movement in the opposite direction when in a second position. This innovative shroud design and attachment method offer practical solutions for securing shrouds to pipeline flanges efficiently and securely.
