LARGE PASSENGER SHIPS DAMAGE STABILITY PROBABILISTIC APPROACH • SAFENVSHIP EXTENSION PROGRAMME APPROVED BY • THE PARTNERS AND SENT TO THE EUREKA OFFICE • MAIN GOALS • TO ASSESS THE SENSITIVITY OF “S-FACTORS” (CONTRIBUTION OF WEATHERTIGHT DOORS – A CLASS FIRE BARRIER ON UPPER DECKS IN ADDITION TO STANDARD WATERTIGHT BULKHEADS-WATERTIGHT DOORS) • TO SIMULATE BY MEAN OF SaS “PROTEUS” TOOL, DIFFERENT FLOODING SCENARIOS IN A SERIES OF PASSENGER VESSELS AND SOME CARGO VESSELS FOR HARMONIZATION • TO VALIDATE THE SIMULATION WITH DEVOTED MODEL TANK TEST (PROBABILITY TO SURVIVE IN CALM SEA AND UP SEA STATE HS=4) • TO CONTRIBUTE NEW IMO DAMAGE STABILITY REGULATION FOR FINE TUNING
WORK GROUP INVOLVEMENT RINA FINCANTIERI SAFETY AT SEA VIENNA MODEL BASIN DIRECT ACTIVITIES CARNIVAL GRIMALDI MARINTEK CONTRIBUTION
FINCANTIERI VESSEL CALCULATIONS WITH “HARDER PROJECT” PROPOSAL • AND POTENTIAL ALTERNATIVES • FOUR CRUISE SHIPS (RANGE 65000-140000 GRT) • ONE FERRY (PLUS ONE SaS) • ONE CAR CARRIER • ONE CONTAINER CARRIER
TANK TEST ACTIVITIES • (UP FOUR COMPARTMENTS FLOODED) • SELECTION THROUGH THE TIME DOMAIN • SIMULATION “PROTEUS” CODE FROM SaS • 90000 GRT PANAMAX SIZE CRUISE • 110000 GRT “GRAND PRINCESS” TYPE CRUISE VESSEL • 140000 GRT DERIVED FROM “G P” • IN COMPLIANCE WITH STOCKHOLM AGREEMENT PROCEDURE • CALM SEA – SEA STATE UP TO HS=4 • SCALE EFFECT: SUBDIVISION DESCRIPTION, DAMAGE OPENING, PERMEABILITY, AIR DUCTS, CROSS FLOODING DUCTS, ECT.
IN PARTICULAR THE FOLLOWING ASPECTS WILL BE EXAMINED: • TRANSIENT PHASE AND PROGRESSIVE FLOODING • FINAL CALM WATER EQUILIBRIUM • IRREGULAR SEA BEHAVIOUR • COMPLIANCE WITH EVACUATION REQUIREMENT • AND SURVABILITY OF LARGE PASSENGER VESSELS
TIME SCHEDULE: • WITHIN DECEMBER 2004: RESULTS OF INDEX A FOR TWO CRUISE VESSELS, ONE FERRY AND A CONTAINER VESSEL USING PROPOSED REGULATION • WITHIN FEBRUARY 2004: • COMPLETION OF THE CALCULATION OF INDEX A FOR REMAINING VESSELS (TWO CRUISES, ONE FERRY AND CAR CARRIER) • CALCULATION OF THE INDEX A FOR THE AFOREMENTIONED SHIPS WITH ALTERNATIVE MODELLING (INCLUSIONS OF WATERTIGHT VOLUMES ABOVE BULKHEAD DECK) • WITHIN MARCH 2004: COMPLETION OF PROTEUS ANALYSIS AND TANK TESTS • WITHIN APRIL 2004: COMPLETION OF REPORTING AND RECOMMANDATIONS
