Girders are the rigid frame of the ship whiles stiffeners are the sub-members in between girders or frame. There are horizontal or vertical members that are being fitting during this stage these are the girders and stiffeners. Plate is being joined by submerged arc welding. Plate is being joined together in a horizontal level ground for straight panels, pin jigs are being used to support curved panels wherein not all surface is tangent to the level ground. This is being inserted on the CNC machine computer control board then the machine will cut according to shape of the detailed drawing.ģ.) Fabrication will start from the basic component of the Ship “the Panel”, during this stage this is called the “Panel wise fabrication”. It is sorted according to thickness plate, size of bulb flats, angle bars, etc.Ģ.) Cutting of materials – now a day’s materials are cut by CNC machining, draftsman from the Engineering or Design section of the Shipyard will provide stl or jpeg file drawings, they saved it in a floppy disk or portable USD flash disk. Materials are arranged in such a way that the last that was being filed up on top is the first material to be cut. 1.) Gathering, mobilization and sorting of materials
