MV3601 Stability of Ships Syllabus:
MV3601 Stability of Ships Syllabus – Anna University Regulation 2021
OBJECTIVES:
• To impart the Knowledge on the Basic Hydrostatics and Stability Calculations of Ship.
• To understand and apply the law of the Archimedes principle, floatation and displacement.
• To understand and calculate the Centre of gravity & effect of addition of mass.
• To determine the Meta centric Height, free surface effect and Carry out the Inclining experiment.
• To derive the loss of stability due to grounding.
UNIT I HYDROSTATICS
Density, relative density, pressure exerted by a liquid on an immersed plane, center of pressure, load on immersed plane, load diagram, shearing forces on bulk head stiffeners– problems.
UNIT II GEOMETRY AND SHIP FORM CALCULATION
Archimedes principle, Laws of floatation, displacement, tonne per cm immersion. Coefficients of form, wetted surface area, similar figures, shearing force and bending moment – problems.
UNIT III CALCULATION OF AREA, VOLUME, FIRST AND SECOND MOMENTS
Simpsons first rule and second rule, application to area and volume, use of intermediate ordinate rule, trapezoidal rule, mean and mid – ordinate rule, application of 5,8, – 1 Rule for area, application of simpson rule to first and second moments of area – Centre of gravity, effect of addition of mass, effect of movement of mass, effect of suspended mass – problems.
UNIT IV TRANSVERSE STABILITY AND HEEL
Static stability at small angles of heel, calculation of BM and meta centric height, meta centric diagram, inclining experiment, free surface effect, stability at large angles of heel, curves of static stability, dynamic stability, angle of loll, stability of a wall sided ship –inclining experiment, problems. IMO recommendations concerning ship stability.
UNIT V LONGITUDINAL STABILITY
Longitudinal BM – MCT1 cm – Change of trim, change of LCB with change of trim, alteration of trim by adding or removing weights, mean draft, change in mean and end draft due to density and bilging – flooding calculation – floodable length – factor of sub division – loss of stability due to grounding – problems- Knowledge of Trim and stress tables and equipment’s.
