To provide a deck stringer structure of a multi-decked ship capable of keeping a maximum waterline as originally planned even when ship specifications are changed.SOLUTION: A thickened deck stringer 20 with a plate thickness increasing upward in a part of a ship longitudinal direction is used as a deck stringer for attaching a freeboard deck 7 to a side plating 2 in a multi-decked ship S. As a result, a load waterline WL can be raised since a freeboard fb can be determined on the standard of the upper surface of the thickened deck stringer 20. The reduction of the maximum cargo payload can be minimized by the minimum increase of a hull weight since the thickened deck stringer 20 is the part in the ship longitudinal direction.SELECTED DRAWING: Figure 1

    【課題】船舶仕様の変更があった場合でも、最大喫水線を当初計画どおりに維持できる多甲板船のデッキストリンガ構造を提供する。【解決手段】多甲板船Sにおいて、乾舷甲板7を船側外板2に取付けるためのデッキストリンガとして、船長方向の一部において板厚を上方に向けて厚くした増厚デッキストリンガ20を用いる。増厚デッキストリンガ20の上面を基準として乾舷fbを決定できるので、結果として満載喫水線WLを引き上げることができる。また、増厚デッキストリンガ20は船長方向の一部であるので、最小限の船殻重量の増加で最大貨物積載量の低減も最小限にできる。【選択図】図1
