Damage stability requirements for passenger ships : collision risk based cost benefit assessment

Currently built passenger ships have to comply with SOLAS 2009 probabilistic damage stability requirements. There are, however, serious concerns regarding the sufficiency of these requirements with respect to the Required Subdivision Index R, which should properly account for the risk of People On Board (POB) and ship’s inherent survivability in case of loss of her watertight integrity. In recent years extensive research on determining the appropriate level of R using risk-based methods has been carried out. The urgency of the matter was reinforced by the quite recent Costa Concordia (2012) accident, even though this accident was not related to a collision event. This paper outlines the objectives, the methodology of work and first results of the ongoing studies funded by EMSA (EMSA III project) focusing on risk-based damage stability requirements for passenger ships. In compliance with IMO Formal Safety Assessment process a collision risk model is further developed based on the results of EU GOALDS project and a new required index shall be suggested by means of cost-benefit assessment. The updated collision risk model uses information from the most recent analysis of casualty reports of databases considering the period 1990 to 201

Damage Stability of Ro-Pax Ships with Water-on-Deck

ABSTRACT Currently European ro-ro passenger ships constructed after 1 January 2009 must comply with both the new SOLAS2009 probabilistic damage stability requirements and the Stockholm Agreement allowing for water accumulation on the vehicle deck (WOD). Doubts in some European states over whether SOLAS2009 makes sufficient provision for WOD led to the EU decision to retain Stockholm; this was partially reinforced by results from three new research projects, completed in 2009, which revealed potential weaknesses in the probabilistic regulations, particularly for smaller ro-pax ships and those with long lower holds. This paper gives some historical background and outlines some of the steps being taken to rectify the current regulatory situation

Analysis of recent marine pollution problems and effects arising from sea transport activities in Jakarta Bay

This dissertation, a study of the “Analysis of Recent Marine Pollution Problems and Effects Arising from Sea Transport Activities in Jakarta Bay”, was prepared for the Research and Development Agency under the Indonesian Ministry of Communications. The results of the study are applicable to other areas of Indonesian territorial waters. as the problems related to sea transportation seem to be of a similar nature in most areas. Marine pollution problems and effects are only one of the environmental problems that the world faces today. However, it has afar and wide-reaching impact on the globe and its population, thus making it one of the most important subjects in global environmental issues around the world. Although marine pollution problems come from various sources, those which come from sea transportation are given more public attention because of their potential threat to the marine environment. Many of the international regulations relating to marine pollution prevention are the outcome of marine accident problems which have caused extensive oil spills. Legislation has been concerned with new designs. structure and equipment. But, it cannot be fully effective until the human element is committed to safety and possesses a high respect for the environment. This study endeavers to provide an understanding of the current condition of Jakarta Bay, polluted by human activities, especially sea transport activities. In this connection, the study also endeavers to provide a framework for incorporating an environmental protection policy in the Indonesian sea transportation system to raise the awareness of Indonesian sea transport operators. The approach discussed in this study is the integration of pollution prevention and environment protection through the identification of the present problems and scope of marine pollution from sea transport activities, and analysis of the impact created by sea transport on the marine environment of Jakarta Bay. Other important effective tools to protect our environment are also examined. These include setting up environmental impact and risk assessment of sea transport activities, analysis of sources and effects of marine environment pollution from sea transport activities. scientific guidance on pollution issues attributable to sea transport activities, and the application of international, regional and national legal instruments or regulations. The concluding chapters offer measures to improve existing environment conditions of Jakarta Bay, and discuss the potential use of legal instruments and regulations, international. regional and national, to integrate marine pollution prevention and environmental protection in Indonesian territorial waters. The interplay between international or regional environmental policy and national action is emphasised to achieve an effective sustainable development program in the maritime sector
