A closure arrangement for an underwater equipment tunnel, said equipment tunnel (PT) being located in a hull (H) of a watercraft (WC), below a waterline (WL) of the water- craft. The equipment tunnel has a specific diameter (D1) and an inner surface (S). The closure arrangement (11, 2) comprises a closure element, which at least partially covers a surface corresponding to the inner surface of the equipment tunnel, and which is removably installable in the equipment tunnel. In order to provide a conveniently and quickly removable closure arrangement, the closure arrangement comprises a frame element directly and re- movably fast enable to the inner surface (S) of the equipment tunnel (PT), and an adaptation element supported on the frame element for sealing the closure element of a flexible material against the inner surface of the equipment tunnel.
