Inner explosion resistant membrane door for a marine vessel

Inner explosion resistant membrane door for a marine vessel An inner membrane door (31) for a marine vessel comprises a first plate (32) with an opening (34) enclosed by a peripheral edge; a door connected to this first plate by a hinge construction; the door sealingly co-acting with said peripheral edge (33). The peripheral edge comprises a plate part (51) having a wave shape with at least one wave. The door (37) comprising a second plate or door leaf (45) of stainless steel, in particular of 316L, which second plate or door leaf is received in a framework (46) which co-acts sealingly with the peripheral edge in a closed position. The peripheral edge is deformable under the influence of an air pressure load acting on the membrane door in the closed position such that at least the door can be pressed out of the main plane it occupies when at rest while maintaining the co-action between the framework and the peripheral edge, and while providing mechanical integrity and fracture resistance to the inner membrane door for a marine vessel
