  1. Marine Kit-4 Ship Disaster Investigation www.TheMarineTech.org

  2. Ships: Mode of Transportation Clipper Ship Tanker Ship Aircraft Carrier Economical as well as technological development of ships and shipping industry has been phenomenal over the past few centuries. Modern supertankers, bulk carriers and aircraft carriers have evolved from the age old clipper ships 2

  3. Classification of Ships According to Usage • Bulk Carriers, Tankers, container ships are used for transportation of cargo (oil, ores, grains, etc) • Cost effective way of transportation • Aircraft Carriers, Submarines, Frigates, etc play key role in defense • Technologically superior ships • Used for transportation of passengers • Cruise ships have major contribution to tourism industry

  4. Ship Safety

  5. Safety: Big Issue for Ocean-going Vessels Safety of ships, cargo, crew and passenger ships is the most critical Any flaw in design, construction or operation of ship can cause disasters like “Titanic”

  6. Dangers Uneven Loading Storm / Heavy Seas Fire Human Errors Faults in Design / Construction

  7. Ship Disasters: Case 1 RMS Titanic Sank : April 15, 1912 1517 People died Cause: Titanic struck an iceberg broke apart into 2 pieces Sinking of Titanic had major impact on the design of ships. While Titanic had double bottom, she did not have double hull. After her sinking, new ships were designed with double hull and fully extended watertight bulkheads

  8. Ship Disasters: Case 2 SS Edmund Fitzgerald Sank: November 10, 1975 All 29 crew members perished Cause: Gale Storm Fitzgerald took on water through the damaged cargo hold covers and was then overwhelmed by the gigantic waves

  9. Ship Disasters: Case 3 Exxon Valdez On March 24, 1989 she ran aground on Bligh Reef in Prince William Sound Alaska It spilled 11 million gallons of crude oil, one of the largest spills in human history Caused major threat to flora and fauna in the region

  10. Basic Ship Terminology

  11. Starboard Stern Bow Port Starboard: Right side of the ship Port : Left side of the ship Bow : Front part of the ship Stern : Rear part of the ship

  12. Ship: A Big Floating Body Roll: Rolling is the motion of a floating body about the longitudinal axis ( axis along the length of the body) Pitch: Pitching is the motion about the transverse axis of the body (i.e. axis along the width of the ship. Yaw: Yawing is the motion of a floating body about the vertical axis. Terminology

  13. Draft of a ship is the vertical distance between the waterline and the bottom of the hull Freeboard of a ship is the vertical distance above the waterline Beamof a ship is the width of a ship at any cross section

  14. Ship Disaster Investigation Activity

  15. Contents of the Kit • Ship Disaster Investigation Agency Agent’s Guide • Ship Disaster Case • Check sheet Things Needed • Calculator

  16. General Guidelines • Simulation involves analysis of ship disaster case studies. Students play role of Ship Disaster Investigation Agency (SDIA) agents analyzing the ship disasters • SDIA agents identify the possible causes for the disaster • This activity requires 2 class periods • During the first period study the case, identify the reasons for the ship disaster by consulting the SDIA agent’s guide • Present the findings in the given format during the second period

  17. Day 1 Analysis of Ship Disaster Cases

  18. Disaster Case Study • Form investigation teams of 4-5 students each • Each team gets one ship disaster case to analyze • Read the case carefully • Fill the check sheet • Look for the clues, they can be present in the case description • Consult the SDIA agent’s guide for more technical information • Use conversion factors and formulae if necessary • Find the reasons that caused the disaster

  19. Day 2 Presentation of Findings (Report)

  20. Presentation • Use the standard ship disaster investigation report template • Prepare your report • Identify a team member to present the findings • Present your findings to the class

  21. Case Study Assessment Ship disaster investigation reports will be assessed based on the following quality characteristics • Understanding of the nature of the disaster • Ability of SDIA agents to find the clues • Ability of SDIA agents to find the reasons for the disaster • Presenting the findings of the analysis

  22. Wrap Up • Return the SDIA agent’s guide to the teacher
