Marine Kit-4 Ship Disaster Investigation www.TheMarineTech.org Alok Verma 6/09 Lean Institute ODU 1 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 Alok Verma 6/09 Lean Institute ODU 2 Classification of Ships According to Usage Ships

Merchant Ships Defense Bulk Carriers, Tankers, container ships are used for transportation of cargo (oil, ores, grains, etc) Aircraft Carriers, Submarines, Frigates,

etc play key role in defense Cost effective way of transportation Technologically superior ships Alok Verma 6/09 Lean Institute ODU Passenger Used for transportation of

passengers Cruise ships have major contribution to tourism industry 3 Ship Safety Alok Verma 6/09 Lean Institute ODU 4 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 Alok Verma 6/09 Lean Institute ODU 5 Dangers Storm / Heavy Seas Fire

Human Errors Uneven Loading Faults in Design / Construction Alok Verma 6/09 Lean Institute ODU 6

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 Alok Verma 6/09 Lean Institute ODU

7 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 Alok Verma 6/09 Lean Institute ODU 8

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. Alok Verma 6/09 Lean Institute ODU 12

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 Beam of a ship is the width of a ship at any cross section Alok Verma 6/09 Lean Institute ODU 13 Ship Disaster Investigation Activity
