SCS 4 - Ship Construction and Stability 4 NAUT 1864

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.
