Cargo ship hatch cover
Hot sale made in china marine steel cargo ship roll stowing hatch cover
Steel hatch covers remain at the very core of our business and today we are proud to offer optimised cargo handling systems, including not only hatch covers, but also bulkheads, cell guides, container stanchions, lashing bridges etc.
We know our customer's businesses and can offer specific solutions to support the ship's cargo profile.
Our large production capacity combined with a well-planned production network provides the flexibility to arrange the right slot for each project. We maintain high standards of quality and we make the installation process of the hatch covers as easy as possible. We can manage the risks throughout the entire steel structure process, from design to commissioning and provide spare parts and maintenance throughout the ship's lifetime, thus helping to enhance the ship's second-hand value.
Hatch cover steel structure
For stable and smooth operation of the hatch covers on board, the panels should be stiff. However, to maintain weathertightness at sea, the steel structure of a hatch cover, as well as the bearing pad and sealing arrangements must adapt to the varying shape of the coaming top while the hull is working and flexing at sea. The optimal stiffness of the steel structure of a hatch cover panel is a compromise between the above issues. The correct stiffness is achieved by selecting the optimal proportion between the open web and box construction, the double-skin construction being the stiffest design.
Keeping the deadweight of the vessel under control and maintaining the stability calls for the use of high tensile steels in the main members of the hatch covers. In case of container ships, the size of the containers dictates the arrangement of the main girders carrying the loads and conveying the forces from the hatch cover to the coaming and hull structures. Keeping the structure simple, i.e. the number of components optimised, promotes production cost efficiency and facilitates the production of high quality surface treatment.
