Ship Hull Structure Elements

We will quickly go through the basic terms that are required to understand a design.

Ship hull structure elements. They connect structure that is part of the basic hull girder structure that is designed for overload and structure of secondary importance. For understanding a hull structure it is important to know the basic terms. Terms in ship hull design. The focus is on various types of intact structural behavior building upon concepts from mechanics of materials and statics.

The course is intended to develop the student s knowledge of ship structures. Shipright procedure for ship units and appendix b 2 3 1. Hull girder internal structure and superstructure. The secondary hull loads bending and strength are those loads that happen to the skin structure of the ship sides bottom deck between major lengthwise subdivisions or bulkheads.

A hull is the watertight body of a ship or boat. A beam is a structural element that increases load bearing capability and avoid bending of the structure. For these loads we are interested in how this shorter section behaves as an integrated beam under the local forces of displaced water pushing back on the hull cargo and hull and machinery weights etc. Iso 15401 2000 ships and marine technology bulk carriers construction quality of hull structure 90 93.

Hull form lines lengthwise and in cross section. Beams can be categorized by many types but from point of ship construction we need to categorize it through cross sectional shape. Relations of elements 90 20. For example there are l shaped beams c shaped beams i shaped beams and si shaped beams.

Changes to 2018 edition. Ship structural details are important because. A1 2 4 load applications and boundary conditions a1 2 4 1all simultaneously acting hull girder and local loads are to be applied to the model. The ship hardware can be roughly divided into two categories.

Frame it is a steel plate that runs longitudinally or transversely throughout the hull structure. April 1 2019 april 1 2019 admin. Axial bending shear cyclic and dynamic. Frames are welded to the sides of the hull as shown in the.

The selection of a structural framing system in any vessel must be made from a consideration of weight to be minimized production matters to be accessible for welding ndt suitability to resist global loads and vibration. Shipbuilding topology of ship hull structure elements part 3. The hull may open at the top such as a dinghy or it may be fully or partially covered with a deck atop the deck may be a deckhouse and other superstructures such as a funnel derrick or mast the line where the hull meets the water surface is called the waterline. The application of local and hull girder loads to the finite element model is to be in accordance.

Ship structural details are subject to various loads and combinations of loads.
