  • Formal Safety Assessment of a Marine Seismic Survey Vessel Operation, Incorporating Risk Matrix and Fault Tree Analysis
    Journal of Marine Science and Application, 2020
    Co-Authors: Gregory Asuelimen, Eduardo Blanco-davis, Zaili Yang, Jin Wang, Dante Benjamin Matellini
    Abstract:

    In maritime Safety research, risk is assessed usually within the framework of Formal Safety Assessment (FSA), which provides a Formal and systematic methodology to improve the Safety of lives, assets, and the environment. A bespoke application of FSA to mitigate accidents in marine seismic surveying is put forward in this paper, with the aim of improving the Safety of seismic vessel operations, within the context of developing an economically viable strategy. The work herein takes a close look at the hazards in North Sea offshore seismic surveying, in order to identify critical risk factors, leading to marine seismic survey accidents. The risk factors leading to undesirable events are analysed both qualitatively and quantitatively. A risk matrix is introduced to screen the identified undesirable events. Further to the screening, Fault Tree Analysis (FTA) is presented to investigate and analyse the most critical risks of seismic survey operation, taking into account the lack of historical data. The obtained results show that man overboard (MOB) event is a major risk factor in marine seismic survey operation; lack of training on safe work practice, slippery deck as a result of rain, snow or water splash, sea state affecting human judgement, and poor communication are identified as the critical risk contributors to the MOB event. Consequently, the risk control options are focused on the critical risk contributors for decision-making. Lastly, suggestions for the introduction and development of the FSA methodology are highlighted for safer marine and offshore operations in general.

  • Formal Safety Assessment of fishing vessels: risk and maintenance modelling
    Journal of Marine Engineering and Technology, 2014
    Co-Authors: A Pillay, T Ruxton, A Wall, Jin Wang, C. G. Loughran
    Abstract:

    Comparisons of the Safety record of the fishing industry with other industrial sectors indicate that it continues to be the most dangerous occupation by a significant margin. Satety data from fishing vessels are scarce and often accompanied with a high degree of uncertainty. For this reason the use of conventional probabilistic risk Assessment may not be well suited. This paper proposes two novel approaches for risk and maintenance modelling of fishing vessels. An approach using fuzzy set theory (FST) is developed to model the occurrence likelihood and consequences for the identified hazards on a fishing vessel. As the time between maintenance opportunities of a fishing vessel can vary considerably, it allows for failures on the machinery to propagate and lead to a catastrophic breakdown. A model using delay time analysis (DTA) is proposed to ascertain the optimal inspection period for fishing vessel equipment depending on the criteria selected. The two criteria modelled are down time and cost. As both these criteria may not be satisfied simultaneously, a best compromise is proposed. Test data from an ocean going trawler are used to demonstrate the two proposed approaches and the results obtained are discussed in detail.

  • incorporation of Formal Safety Assessment and bayesian network in navigational risk estimation of the yangtze river
    Reliability Engineering & System Safety, 2013
    Co-Authors: Di Zhang, Zaili Yang, A Wall, Jin Wang
    Abstract:

    Formal Safety Assessment (FSA), as a structured and systematic risk evaluation methodology, has been increasingly and broadly used in the shipping industry around the world. Concerns have been raised as to navigational Safety of the Yangtze River, China's largest and the world's busiest inland waterway. Over the last few decades, the throughput of ships in the Yangtze River has increased rapidly due to the national development of the Middle and Western parts of China. Accidents such as collisions, groundings, contacts, oil-spills and fires occur repeatedly, often causing serious consequences. In order to improve the navigational Safety in the Yangtze River, this paper estimates the navigational risk of the Yangtze River using the FSA concept and a Bayesian network (BN) technique. The navigational risk model is established by considering both probability and consequences of accidents with respect to a risk matrix method, followed by a scenario analysis to demonstrate the application of the proposed model.

  • Application of Formal Safety Assessment to Navigational Risk Evaluation of Yangtze River
    Volume 2: Structures Safety and Reliability, 2011
    Co-Authors: Di Zhang, Zaili Yang, Xinping Yan, Jin Wang
    Abstract:

    Formal Safety Assessment (FSA), as a structured and systematic risk evaluation methodology, has been gradually and broadly used in the shipping industry nowadays around the world. Concerns have been raised to navigational Safety of Yangtze River, known as China’s largest and the world busiest inland waterway. With the national development of the Middle and Western parts of China, the throughput and the passing ships in Yangtze River have been rapidly increasing during the past few decades. Meanwhile, accidents such as collisions, groundings, overturns, oil-spills and fires occur repeatedly, causing serious consequences. In view of this, attempts made in this paper are to evaluate the navigational risk of Yangtze River using the FSA concept and a Bayesian Network (BN) technique, so as to enhance the navigational Safety in Yangtze River.Copyright © 2011 by ASME

  • A decision-making framework to reduce the risk of collisions between ships and whales
    Marine Policy, 2019
    Co-Authors: Maxime Sèbe, Kontovas Christos, Pendleton Linwood
    Abstract:

    Ship strikes are one of the main human-induced threats to whale survival. A variety of measures have been used or proposed to reduce collisions and subsequent mortality of whales. These include operational measures, such as mandatory speed reduction, or technical ones, such as detection tools. There is, however, a lack of a systematic approach to assessing the various measures that can mitigate the risk of ship collisions with whales. In this paper, a holistic approach is proposed to evaluate mitigation measures based on a risk Assessment framework that has been adopted by the International Maritime Organization (IMO), namely the Formal Safety Assessment (FSA). Formal Safety Assessment (FSA) is "a rational and systematic process for assessing the risk related to maritime Safety and the protection of the marine environment and for evaluating the costs and benefits of IMO's options for reducing these risks". The paper conceptualizes the use of a systematic risk Assessment methodology, namely the FSA, to assess measures to reduce the risk of collisions between ships and whales.

  • Facilitating the treatment of uncertainty in marine Formal Safety Assessment
    2006
    Co-Authors: A. G. Eleye-datubo, A Wall, A. Saajedi, Jin Wang
    Abstract:

    In spite of progress made since the International Maritime Organisation's adoption of Formal Safety Assessments and their trial application to high speed passenger catamaran ferries and bulk carriers, the treatment of uncertainty is still a major barrier to successful implementation. Depending on the type of uncertainty experienced, a sound theoretical treatment can be applied via a risk-based modelling analogy in order to permit the inference process. The approaches available to tackle the different forms of uncertainty are those of probabilistic analysis, evidential reasoning and possibilistic analysis. In this paper, a Bayesian network is shown to realistically deal with those encountered random uncertainties in a typical FSA study whilst at the same time providing a powerful practical decision-support solution platform. The feasibility of the method is given for a marine evacuation scenario developed via a commercial computer tool.

  • Formal Safety Assessment of cruise ships.
    Tourism Management, 2004
    Co-Authors: Petros Lois, A Wall, J. Wang, T Ruxton
    Abstract:

    Abstract This paper examines the applicability of Formal Safety Assessment to the cruise industry. Formal Safety Assessment and its development in the cruise shipping industry are described. Cruise ship accident statistics are studied and discussed. This is followed by an analysis of cruise ship characteristics and a proposed Formal Safety Assessment methodology for cruise ships. A case study is carried out in order to demonstrate the proposed methodology. Further development in Formal Safety Assessment in the context of cruise ship Safety is finally discussed in detail.
