University of Science and Technology of Southern Philippines Department of Naval Architecture and Marine Engineering Introduction to Damage Stability NA 5: Damage Stability WTh 1:00PM – 5:30 PM|ITB Comlab Instructor: Engr. Dweena Maye V. Zamora TABLE OF CONTENTS Introduction Historical Timeline Example Plate 1 Instructor’s Tips & Contact Details Introduction Introduction HOW CAN WE PROTECT OUR VESSELS FROM ACCIDENTAL FLOODING? Introduction Add watertight Add double bulkheads bottoms Introduction Challenges: Location and extent of damage is unknown in advance Amount, type, and location of cargo/liquid varies during and between voyages Corrective measures might not be followed by ship officers Subdivisions will add to the cost and weight of the ship (unsinkable ship may not be economic) Historical Timeline 19th Century addition of fore and aft peaks, and bulkheads separating machinery space from the cargo holds 1929 SOLAS Convention improved in 1936 due to the ff: SS Mohawk (1935) SS Morro Castle (1930) Historical Timeline 19th Century 1948 and 1960 SOLAS Convention resulted in the increase of ships required to meet the 2-compartment standard: “A ship can remain afloat even after complete damage to any of its two adjacent watertight compartments,” Flooded Compartments Historical Timeline 19th Century After 1970, subdivisions were not only limited to passenger ships anymore but included the ff: - Bulk Chemical Carriers - LNG Carriers - Tankers - Mobile Offshore Drilling Units Historical Timeline Current: Analysis of floodability and stability in longitudinal and transverse directions with advanced softwares Example Plate 1 Instructions: Form a group of at most three (3) people each.
