(57) A transverse propulsion device (1) of a ship (2) comprising a maneuvering tunnel
(3) defined in a hull (4) of the ship (2) and adapted to contain at least one maneuvering
propeller (5); said maneuvering tunnel (3) being delimited by tunnel walls (6), which
extend between a first tunnel entrance (7) and an opposite second tunnel entrance
(8); at least one coupling (9), which extends from the tunnel walls (6) at the at
least one tunnel entrance (7, 8); at least one support structure (10), comprising
at least one counter-coupling (27); said support structure (10) being connected in
a separable manner with said at least one counter-coupling (27) thereof to said at
least one coupling (9); said transverse propulsion device (1) further comprising at
least two closing doors (12) shaped so as to close the at least one tunnel entrance
(7, 8), as a whole, when in the closing position; wherein at least one support structure
(10) comprises hinges (11); and wherein said at least two closing doors (12) are rotatably
hinged only on said hinges (11) of the support structure (10), so that, when said
at least one counter-coupling (27) of the support structure (10) is separated from
said at least one coupling (9), the closing doors (12) separate from the maneuvering
tunnel (3), together with the support structure (10), thus allowing access to the
maneuvering tunnel (3).
