NAUT 1864 - SCS 4 - Ship Construction and Stability 4

Ocean Navigation Part-time Studies Course

School of Transportation

Course Details

This course combines knowledge of ship's principal structural members, strength, and the use of the ship's stability information booklet to calculate the vessel's stability condition in order to maintain seaworthiness. The course also includes knowledge and application of the computer software used to calculate stability and hull stresses (bending moments and shearing forces) on modern ships.

Learning Outcomes

Upon successful completion of this course, the student will be able to:

  • Explain the purpose of load lines.
  • Calculate displacement of a ship at various drafts.
  • Calculate metacentric height (GM).
  • Differentiate between stiff and tender ships.
  • Determine new drafts after loading, discharging, and shifting weights on board.
  • Calculate the effect of free surface and apply it to find the fluid GM.
  • Define angle of loll and dangers associated with it.
  • Calculate the angle of list from loading, discharging, or shifting weights.
  • Calculate the increase in draft due to heel.
  • Calculate true mean draft.
  • Explain the effect of wind and water on deck.
  • Explain the damage stability criteria for different types of ships.
  • Calculate draft and trim of a vessel from loading, discharging, or shifting weights.
  • Calculate final drafts and trim using ship's stability data book for a typical vessel.
  • Determine ship's stability using computer software.
  • Determine bending moments and shearing forces using computer-based software.
  • Calculate water pressure at any depth below the liquid surface.
  • Draw a statistical stability curve for ship's loading condition using KN curves and GZ (righting lever) cross curves.
  • Calculate area under the GZ curve using Simpson's rules to determine ship's compliance with load line rules.
  • Identify ship's structural components on plans and drawings.
  • Sketch and describe various structural members on a vessel.
  • Describe and sketch construction of weather deck mechanical steel hatch covers with its securing arrangement.
  • Draw a balanced, semi-balanced, and un-balanced rudder.
  • Compare fixed pitch and variable pitch propellers.
  • Distinguish between Type A and Type B ships for the computation of freeboard.
