The new probabilistic and more risk based subdivision and damage stability rules have brought many changes and more flexibility to the subdivision requirements for passenger ship designs. Whilst designers are still adapting to the fundamentally changed SOLAS requirements, applicable January 1st 2009, many additional items remain on the agenda of IMO addressing the stability of passenger ships. Additional damage stability regulations for ro-ro passenger ships as well as requirements towards stability and sea-keeping characteristics of damaged passenger ships in a seaway when returning to port by own power or under tow are among the topics that are currently being addressed. These could have considerable impact on future passenger-and ro-ro passenger vessel designs. Stability of Passenger Ships The new probabilistic and more risk based subdivision and damage stability rules have brought many changes and more flexibility to the subdivision requirements for passenger ship designs.

This paper provides a succinct summary of the findings ensuing the undertaking of a dedicated EU-funded research project aiming to address the impact of the Stockholm Agreement (SA) on the EU Ro-Ro passenger ships. This is achieved by utilizing the experience gained, the data and knowledge accumulated through the adoption of the Stockholm Agreement in North West Europe to form the basis for predicting the likely impact of introducing this Agreement to vessels operating in EU waters not covered yet by it. The background, including a historical overview and a detailed introspective look at the SA, together with an assessment of its impact on passenger Ro-Ro ship safety standards, design and operation are presented in a companion paper (Part 1) in the July 2002 issue of MARINE TECHNOLOGY.

This paper opens with a brief historical review and then discusses design and construction of self-propelled U.S.-flag passenger vessels from 50 to 200 ft in length. Technical topics include hydrodynamics, hull form, structure, weights, trim, subdivision, stability and machinery. A discussion of regulatory standards and the effect of the regulatory process on the industry is included.

A Multi-Level Approach for Flooding Risk Estimation and Assessment of Passenger Ships

Against the background of using the Index of Subdivision as a reference to address the safety level of ships when damaged, following primarily collision accidents, the EC-funded FLARE project is making inroads towards a direct assessment of the flooding risk, which is ship specific and considers the operating conditions and all accident-types leading to hull breach and flooding, namely collisions, bottom and side groundings. This is enabled by using a newly developed two-level approach Potential Loss of Life (PLL) of People On Board (POB); level 1 is a semi-empirical approach with the risk models formulated by use of data from a newly composed accident database, while level 2 is determining the flooding risk by a first principles approach, using time-domain flooding and evacuation analyses simulation tools in pertinent emergencies. Level 2 is considered in two sub-levels (Level 2.1 and Level 2.2), the former involving some simplifying assumptions in the risk calculation. In addition to addressing all accident types and modes of loss of ship and of POB, the FLARE framework and methodology considers active and passive measures of risk prevention and control, hence with application potential to both newbuildings and existing ships. It also facilitates real-time flooding risk evaluation for risk monitoring and effective control in emergencies. Key objectives of the FLARE project are to provide the technical basis for the rational determination and assessment of flooding risk and to prepare a proposal for the revision of relevant IMO SOLAS regulations towards a risk-based approach to contain and control flooding emergencies. The paper briefly describes the FLARE flooding risk assessment framework and provides risk estimation results at all three levels for one cruise ship and one RoPax, including comparisons with available IMO societal criteria, as well as a summary of results for a further 7 ships at levels 2.1 and 2.2. In the light of the results presented, the paper draws conclusions on the progress made and offers recommendations for the way forward.

Against the background of using the Index of Subdivision as a reference to address the safety level of ships when damaged, following primarily collision incidents, the EC-funded FLARE project is making inroads towards a direct assessment of flooding risk, which is ship, operating environment, and accident-type specific by addressing all the underlying elements, using a two-level approach; level 1 being semi-empirical with risk models informed through a newly composed accident database and level 2 with flooding risk, in the form of Potential Loss of Life, calculated from first principles, using time-domain flooding simulation tools and evacuation analyses in pertinent emergencies. In addition to addressing all accident types and modes of loss, the FLARE framework and methodology target active and passive measures of risk prevention and control, hence with application potential to both newbuildings and existing ships as well as facilitate realtime flooding risk evaluation for risk monitoring and effective control in emergencies. A key objective of the FLARE project is to provide the technical basis and a proposal for the revision of relevant IMO regulations towards a risk-based approach to contain and control flooding emergencies. The paper provides a complete example of one cruise ship and one RoPax where levels 1 and 2 of flooding risk evaluation are presented and discussed, and a summary of results for a further 8 sample ships from Project FLARE, leading to conclusions on the progress made and recommendations for the way forward.
