A drainage channel for a gangway bellow comprising corrugations forming at least one valley presenting a valley top portion facing upwardly and at least one valley top corner, wherein the drainage channel is suitable for being located within said at least one valley top corner of said at least one valley and is operative to guide at least partially downwardly liquid accumulating within said valley top portion as it flows through said drainage channel,
- wherein the drainage channel comprises:
- at least one top corner portion at one end suitable for being located into said at least one valley top corner of said gangway bellow, and
- a straight portion extending downwardly from said at least one top corner portion along at least part of a bellow side, and
- wherein said straight portion is located within at least part of a valley side portion facing outwardly and extending downwardly from said valley top portion along said bellow side.
A gangway bellow comprising an outer bellow presenting corrugations forming a plurality of valleys presenting each a valley top portion facing upwardly and connected at each end to a valley top corner connecting one end of said valley top portion and a bellow side, wherein said gangway bellow comprises at least one drainage channel,
- wherein said at least one drainage channel comprises a top corner portion located within at least one of the valley top corners and a substantially straight portion connected to said top corner portion located within at least part of a valley side portion facing outwardly and extending downwardly from said valley top portion along said bellow side so that liquid accumulating into the respective valley top portion flows downwardly through said top corner portion and said substantially straight portion of said at least one drainage channel along said respective bellow side.
