Background
Bulk carriers are divided into several cargo holds for loading cargo respectively, and the vertical tank bulkheads are used for separating the cargo holds of the ship body and are usually formed by connecting pressed plane steel plates in a welding or bending mode.
Compared with a plane cabin wall plate, the traditional vertical groove type cabin wall does not need to be additionally provided with aggregates, so that the workload of cabin sweeping is reduced, and the structure is cleaner and tidier. However, as an improvement to the planar bulkhead plate, there are some drawbacks, as listed below:
(1) because of the adoption of the combination body of the plane plate, in order to ensure the requirement on the strength, a thicker plate thickness is often needed to ensure the structural strength.
(2) The crossed parts of the groove strip web plate, the panel and the bottom plate are easy to accumulate goods and are not easy to clean.
(3) The welding quality of the intersection points of the three welding lines is not easy to be ensured. Three welds, respectively: the full penetration welding of the groove strip web and the groove strip panel is realized; butt welding the groove strip web plate and the unloading plate; butt welding of the bottom pier sloping plate and the unloading plate. Because the welding is relatively close, and the structure is complicated, welding quality is difficult to obtain the assurance.
