The continuous monitoring and assessment of operational vulnerability accident susceptibility passenger ships is crucial from the perspective ship safety. Despite existing solutions for monitoring, stemming mainly watertight door operations, a comprehensive framework missing in literature. Therefore, this paper offers straightforward approach, utilizing heuristics rooted solid foundations first principles related to human performance. proposed approach allows evaluation operation involved...
Survivability of damaged ships, especially ro-ro/passenger (ropax) vessels, is paramount interest. Nowadays, time-domain simulation flooding and motions ships are more frequently performed to obtain a realistic overview the actual survivability in case accident. An international benchmark study on ropax vessels was conducted within EU Horizon 2020 project FLARE, using new dedicated model tests as reference. The test cases include transient both calm water irregular beam seas, well gradual...
Efficient response to maritime incidents and accidents requires good communication processes situation awareness by all involved parties, in particular between the Search Rescue (SAR) operators crew of distressed vessel. In this paper, a method is proposed for enhancing focusing on safety status Borrowing ideas from well-established working methods especially emergency medicine, Vessel TRIAGE has been established through broad stakeholder consultation process. Its intended application assess...
Large cruise ships can carry 10 000 persons onboard, and consequently, survivability of the ship in event a flooding accident is essential. Many designers are already conducting advanced damage stability analyses beyond regulatory requirements. With increased computing capacity, analyses, by using time-domain simulation tools, commonly applied design new ships. Consequently, it essential that such tools properly validated, terms response detailed behavior, to assess capability applicability...
A new approach for analysing the level of survivability a passenger ship in event collision damage is presented. Monte Carlo simulation used generating large number cases. The probability distributions extent and location are based on current SOLAS regulation. Each case calculated with time-domain flooding simulation, assuming quasi-static motions calm sea, thus enabling evaluation righting lever curve during process. analysed requirements sufficient reserve stability. proposed method...
Post-accident safety of ships is governed by damage stability, affected watertight subdivisions which limit accidental flooding. This important for passenger with doors (WTDs) often fitted in the bulkheads. Awareness ship flooding risk due to open WTDs and conditions under associated level changes are prerequisites proactive mitigation. Accident expressed as a combination accident likelihood its consequences. Current solutions mitigation treat these elements separately, or adopted metrics...
Reliable analysis of stability and safety level in a flooding emergency onboard damaged passenger ship is extremely important for making correct decisions on evacuation abandonment. Thus there demand an automated system that detects analyzes the severity situation. This procedure requires estimation actual breach hull, calculation possible progressive to undamaged compartments. A new approach assessment, based measurement data from flood sensors, presented. The developed method complemented...
The current damage stability criteria for ships are mainly based on the characteristics of righting lever curve. related calculations different intermediate stages during flooding process, and final equilibrium condition, generally considered trivial. However, with increased computing capacity regulations developing towards a more realistic assessment flooding. Most notably, time-domain simulation has become viable option. Consequently, practices assumptions to calculation curve damaged ship...
Abstract A decision support system with damage stability analysis has been recognized as an important tool for passenger ships. Various software applications have developed and taken into use over the years, without a direct link to any compelling requirement, set forth in international regulatory framework. After Costa Concordia accident, new regulations established, setting minimum requirements system, extension loading computer. Yet, more advanced systems recently, aiming at providing...
A pressure-correction method with an implicit scheme is used to solve the time accurate distributions of floodwater and air pressure inside a damaged ship. Only progress airflows ship are considered; changes in floating position excluded. The applied three test cases. results show that compression have significant effects on flooding rates.
