A comparative method for scaling SOLAS collision damage distributions based on ship crashworthiness – application to probabilistic damage stability analysis of a passenger ship

Abstract A decision support system with damage stability analysis has been recognized as an important tool for passenger ships. Various software applications have been developed and taken into use over the years, without a direct link to any compelling requirement, set forth in the international regulatory framework. After the Costa Concordia accident, new regulations have been established, setting minimum requirements for a decision support system, as an extension to a loading computer. Yet, more advanced systems have been developed recently, aiming at providing valuable additional information on the predicted development of the stability of the damaged ship. This paper presents these alternative decision support systems with damage stability analysis methods for flooding emergencies on passenger ships. The technical background, usability, and usefulness of the various approaches are compared and discussed, taking into account the important statutory approval point of view. In addition, practical examples, including past accidents, are presented and discussed.

Marginal Field

As the development of offshore marginal field becomes a heated topic, various design selections of offshore platform have already been put forward in the community such as Sevan SSP, IQFP-FPSO, octagonal FPSO or sandglass-type FDPSO. In this paper, a new Muliti-Cylinder FPSO (MCPSO) with section pile foundation is proposed for developing offshore marginal field in South China Sea. And the structure design in detail has been described. The MCPSO consists of six cylindrical concrete tanks and six suction piles. The suction piles can be raised up during platform towing process. Considering the effects of tanks and piles on the towing stability, both intact and damage stability analysis of MCPSO were performed under different towing conditions. The influence of ballast ratio, towing direction and different damaged modes on the towing stability is analyzed. The results indicate that the MCPSO has the characteristics of self-installation, movable, reusable and so on, which is suitable for the development of marginal oil field. The MCPSO filled with 40% seawater in ballast tank and towed in 90 direction has the best intact and damage stability characteristic.

The Stability ◽

Passenger Vessel

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.
