Abstract It is very important that the plate thickness of deck house design and welding joint production design ensures the strength of hull structure and bulkhead arrangement is reasonable。 The deck house material selection and welding specification should conform to the specifications and the actual requirements, and it ensures the safety of navigation of the ship。

The passenger ship as an example and the deck house plate thickness design in the limited conditions (ship, environmental load, set layout requirements) , including the cabin arrangement and skeleton layout as well as the selection and calculation of the

deck，bulkhead and elbow, and the selection of welding methods and calculation of

the specification of the welded joint would be studied。 At the same time, it  is compared to the the Classification Society for the design of the deck of the specifications, and a passenger ship as a case calculation for plate thickness design in practical situations, and the selection of welding method and calculation of throat will be checked。 Finally, the hull deck plate thickness design, the welding joints of the main points of the production design and the specification requirements could be summarized。

Keywords: deck house; passenger ship; plate thickness;Welding method
