Naval Architecture 1A

This module consists of two parts, i.e. Part 1 on Principles of Naval Architecture and Part 2 on Linesplan Drawing.

Part 1 includes methods of numerical integration and quadrature; Calculation of hydrostatics based on areas, volumes and centroids; Metacentric theory and ship stability; Concepts of initial and static stability; Presentation of stability information; Evaluation of stability. This module covers knowledge relating to Archimedes principle, ship stability and fluid dynamics, such as –

i. Archimedes principles; establishing equilibrium; basic naval architectural terms and concepts; basic hydrostatic quantities; numerical interrogation, Simpsons First, Second and Third Rules; calculation of area first and second moments or area; calculation of volume and centroids; calculation of waterplane area, LCF, transverse and longitudinal second moment; calculation of displaced volume, KB and LCB; Metacentric theory and stability; calculation of metacentric radius; calculation of metacentric height and righting level; calculation of KG; the influence of adding or removing mass; the history of shipbuilding; introduction to offshore engineering and small craft technology.

ii.Ship stability; hydrostatic particulars, tabular and graphical presentation; calculation of centres of gravity; shift of the centre of gravity due to adding, moving, or removing a mass; special cases; a suspended load, tanks and free surface effect; flooding calculations; added mass and lost buoyancy methods; longitudinal stability and trim; draught analysis; hogging and sagging, the layer correction; the inclining experiment; introduction to static stability, the Wall Sided formula, cross curves of stability, curves of static stability; stability evaluation; IMO criteria, the Stability Booklet.

Part 2 includes: Linesplan Drawing for ship design, scaling, dimensioning, fairing, profile view, half-breadth view, body plan, offset table
