TITLE Fundamentals of Ship Science

LEVEL 05 - Postgraduate Modular Diploma or Degree Course


DEPARTMENT Mechanical Engineering

DESCRIPTION This study-unit will cover fundamental theory and practical knowledge on:

- ship fundamentals, describing hull form characterisation and hydrostatics; upright, small and large angle intact stability; damage and flooding, describing deterministic, and probabilistic methods and floodable length calculations; regulations associated with stability, damage and flooding are considered such as IS2008 code, SOLAS & MARPOL;

- characterisation of resistance and measuring techniques, friction & residuary, viscous & pressure, energy and force based measurement techniques; empirical scaling methods of quantifying friction resistance and its application, Froude and form factor scaling, plate friction formulae, form factor methods and selected design data and regression analysis, such as Series 60, BSRA, -Holtrop and Mennen;

- axial momentum theory as the rudimentary introduction to propeller science;

- maritime hydrodynamics, focusing on the modeling and analysis of sea waves kinematics, wave-induced loads on structures and dynamic response of floating structures under the combined action of waves, wind, gravity and inertial loads.

Study-unit Aims:

The main aim of this study-unit will be to introduce fundamental theoretical and practical knowledge about ships covering the following topics:

- Ship fundamentals of form, hydrostatics, stability, intact and damage conditions and floodability;
- Fundamentals of resistance and propulsion covering the dual nature of hull resistance and basics of fluid behaviour round a propeller;
- Hydrodynamics, covering the modelling and analysis of waves and wave-induced loads and motions of floating structures.

Learning Outcomes:
