Stability conditions comply with the IMO intact stability criteria under all conditions of loading. Ship Construction General knowledge of the principal structural members of a ship and the proper name for the various parts. Bracket – support the girder, etc Bulkheads – a vertical partition between compartments Center girder – In lieu of longitudinal, provide longitudinal strength Longitudinal framing in DB – Floor – A vertical athwartships member in way of the double-bottom. It will run from the center girder out to the margin plate on either side of the vessel. Frame – Internal support member for the shell plating. Vessel may be framed longitudinally or transversely. Gusset – triangular plate for joining angle bar to a plate Intercostals Side girder – A side girder in the fore and aft line sited either side of the keel. Integral connection with the tank top and the ship’s bottom plating and rigidly connected by floors Keels – center line plate from stem to the stern frame. Flat plate keels – Generally used keel. Center girder is attached to the keel and inner bottom plating by continuous welding and no scallops permitted Duct keels – a form of flat plate keel with tow center girder. Often fitted between collision bulkhead and forward engine room bulkhead to provide tunnel for pipes and additional buoyancy. Lightening holes – holes cut into floors or intercostals to reduce weight and to provide access to tank areas Longitudinal – A fore and aft strength member connecting the athwartships floors. It must be continuous for ship 215m. Additional longitudinal are to be found in pounding area Margin plate – a fore and aft plate sited at t
