Beschreibung
Zusammenfassung:	An in-line accessory structure for a subsea pipeline comprises: at least one mudmat that is movable relative to the frame from a compact stowed state into an extended deployed state; a frame attached to the mudmat; an elongate pipe section supported by the frame, the pipe section being arranged to be integrated into the subsea pipeline; and a branch in fluid communication with the pipe section. At least one mudmat and at least one branch are disposed in longitudinal succession along the pipe section on each side of the pipe section, the mudmats on opposite sides of the pipe section being offset longitudinally from each other to define longitudinally-extending recesses with opposite longitudinal offset that accommodate the branches on opposite sides of the pipe section.
