TOPIC - Introduction to Naval Arcitecture

  • Defines, understands, and uses the following terms used in naval architecture and stability:
    • Initial stability
    • Six motions of a vessel
    • Centers of gravity and buoyancy
    • The couple
    • Indicators of initial and dynamic stability
    • Transverse metacenter
    • Stable neutral and unstable equilibrium
    • Metacentric height
    • Metacentric radius.

TOPIC - Transverse stability

  • Carries out calculations for:
    • Vertical Center of Gravity
    • Height of the Metacenter
    • Height of the Center of Buoyancy
    • Metacentric Radius.
  • Carries out calculations to determine GG' (Shift of center of gravity).
  • Carries out calculations to determine KG when Loading and Discharging.
  • Interprets ship's lines and hydrostatic data.
  • Uses hydrostatic curves in determination of KM, KB, and BM.
  • Approximates BM for curved water planes.
  • Analyzes the vertical movement of KM, and movement of M with transverse inclination.
  • Inspects stability booklets for content.
  • Carries out calculations to determine GM, The Relationship of GM to rolling period, proportionate loss of stability.
  • Understands the effects of negative GM on a vessel.
