Residual stress measurement in an extra thick multi-pass weld using initial stress integrated inherent strain method

Residual stresses existing in a multi-pass butt joint with a thickness of 70 mm, using a flux-cored arc welding process, were measured by an inherent strain method (ISM). Since such a thick plate before welding contains a large amount of initial residual stresses (−300 to +100 MPa), the initial stresses were integrated with conventional ISM in order to determine the total residual stresses in a welded joint. Two methods named as initial stress integrated ISM and initial inherent strain integrated ISM were suggested for the consideration of the initial stress distributions through the thickness of base plates. The results show that there is a significant difference between the integrated ISM with initial stresses or initial inherent strain and the conventional ISM without initial stresses. The residual stresses measured by any of the initial stress integrated ISM and initial inherent strain integrated ISM agreed well with the neutron diffraction measurement. Thus, the proposed initial stress integrated ISM is a proper destructive measurement method in the case of thick weld joints.

ISM Code implementation: an investigation of safety issues in the shipping industry

Acknowledging that shipping safety continues to be a major topic of interest in the maritime community, the present study attempts to identify the critical factors of International Safety Management (ISM) Code implementation, to identify the dimensions that describe whether the ISM Code has fulfilled its intended purpose as well as to assess their interrelationships. Moreover, the present study aims to explore whether the fulfillment of the Code’s intended purpose is associated with accident reduction. Evidence was drawn from a sample of 63 masters and chief officers who have hands-on onboard experience on ISM Code implementation and data were analyzed through the use of Exploratory Factor Analysis (EFA), correlation analysis, and binomial logistic regression. Findings indicate that the critical factors of ISM Code implementation can be categorized in the crew-related and the company-related dimensions. Also, the fulfillment of the intended purpose of the ISM Code consists of the factors of safety management system efficiency and increased safety, which were also found to be significantly associated with the crew-related dimension of ISM Code implementation. Finally, results showed that both safety management system efficiency and increased safety increase the probability of accident reduction at the highest level.     

British Shipping and World Competition[1] revisited

The object of my book British Shipping and World Competitionwas to answer the question: 'Why has the tonnage of ships registered in the United Kingdom declined from over 45% of the world total in 1900 to about 16% of that total in 1960?'. There was never any normative element to this question, a point which has been much misunderstood. In answering the question, two different methodologies were used. Chapters II through VIII are industrial economic history, whereas Chapters IX through XIV are applied economics. When the two groups are thought of as siblings, not as Siamese twins, it can be seen that the first group has worn rather well, but that the applied economics chapters have a distinctly dated air. Most of this article is concerned with the applied economics chapters, where I try to examine what is said in the book in the light of my subsequent experience and thinking. There is one absolutely gross error in the material. Unfortunately, this is implicitly reflected in the Code of Conduct and in the EC Maritime Regulations. The original answer to the question has been rephrased in the article; I hope this will put to rest the idea that the question was normative in intent. The rephrasing does not alter the answer: the decline which needed to be accounted for can be explained solely in terms of internal constraints. The remainder was a 'natural' result of changing international patterns in resource allocation.     

Maritime safety and the ISM code: a study of investigated casualties and incidents

In 1993, the International Maritime Organization adopted the International Safety Management (ISM) Code which requires all shipping companies operating certain types of vessels to establish safety management systems. Nevertheless, two decades later, maritime safety remains a concern. This article studies 94 maritime cases investigated by the Maritime Accident Investigation Branch in the UK. By providing an analysis of reported casualties and incidents, it highlights current challenges in maritime safety. For each casualty and incident, the study reviews the underlying causal factors. These causal factors are then coded according to the functional sections of the ISM Code, covering various aspects of safety management. To investigate human and organizational factors involved in the casualties and incidents, the human factor analysis and classification system (HFACS) is applied to code the same data. Finally, the relative seriousness of casualties and incidents is considered to discuss the findings from ISM Code and HFACS reviews. The study found that the main challenges pertain to the development of plans for shipboard operations, local shipboard management, and the ability of the company to verify when such practices deviate from best practices or required standards.     

Critical factors for successful implementation of the ISM Code in some Pacific Islands states

Although the International Safety Management (ISM) Code was fully implemented from July 1st 2002, not all countries signatories to the Code, particularly developing countries such as Pacific Islands states, are successful in the introduction and implementation of the instrument. In this paper, we aim to determine factors that facilitate the successful implementation of the ISM Code particularly for the above-named region. Through a thorough literature review, a model of 11 critical factors for the Code implementation success was proposed. These factors were empirically tested using the triangulation of a survey of a group of maritime administration personnel and shipping companies in Fiji and two indepth interviews with senior officers in the Samoa Maritime Administration during the period June–August 2007. The proposed factors were verified by both survey respondents and interview informants, i.e., that maritime safety awareness rooted in a safety culture, senior management commitment and leadership across organisations and the industry, employee involvement and empowerment, enforcement capability of flag state administrations, application of quality management principles in safety management systems, rationalisation of documentation, among others, are essential to the successful implementation of the Code. This research hopes to contribute to the literature and to provide maritime administrations and shipping companies in the Pacific Islands states with additional reference and information that will help expedite the effective implementation of the ISM Code. The need for future research directions is expressed in this paper. Additional investigations, e.g., conducting the same research in other Pacific Islands states as well as in other developing countries in the Asia-Pacific region, would enhance the validity and reliability of this study’s findings.

An empirical assessment of ISM Code effectiveness on performance: the role of ISO certification

ABSTRACT

Although the introduction of the International Safety Management (ISM) Code aimed at increasing the safety standards in the maritime industry, several studies conducted so far argue for its inability to successfully fulfill its goals. The purpose of the current study is to evaluate the ISM Code effectiveness by drawing analogy from similar applications of ISO 9001 effectiveness in service companies. It also aims to determine its impact on firm performance and differentiate between ISO and non-ISO-certified shipping companies. Findings indicate that ISM Code effectiveness consists of two dimensions, namely continuous improvement and customer satisfaction focus, and the significance of its contribution on improving company performance is revealed, especially in the case of ISO-certified shipping companies. Moreover, the continuous improvement dimension was found to affect performance at a greater extent.     

Seafarers’ perceptions of competency in risk assessment and management: an empirical study

Past analysis of accident investigations suggest an absence of or inadequate practices of risk assessment and management on board vessels. Although the International Management Code for the Safe Operation of Ships and for Pollution Prevention (ISM Code) requires that the risk management process must not only be correctly formulated and implemented but also be periodically evaluated in order to verify that these objectives are attained, the correct and effective implementation and application of the process cannot be achieved without active involvement of competent seafarers on board. Due to the limited investigation of seafarers’ competencies in risk management, the reasons for the inadequacies in the process that are leading to accidents were not evident. Hence, using a survey, this paper conducted a pilot study investigating seafarers’ perceptions of competency in the various components of the risk management process conducted on board vessels. The findings of this paper suggest an overall satisfaction with the risk assessment process. However, there is certainly room for improvement as far as seafarers’ performance is concerned. The findings of this paper provided valuable insights into the current training regimes in the area of risk assessment and management paving the way towards enhanced safety procedures on board vessels.

Optimum throughput and performance evaluation of marine terminals

The performance of marine terminals has generally been evaluated by comparing their actual throughputs with their optimum throughputs. The engineering approach that generally has been used to determine optimum throughputs may be appropriate when terminals have natural hinterlands. In a deregulated (competitive) environment in which the natural hinterlands of marine terminals have become diffused, the economic approach for determining optimum throughputs should be condiered. In such an environment, marine terminals are not only concerned with whether they can handle a given amount of cargo but also whether they can compete for such cargo.     

The human talent and its role in ISM Code effectiveness and competitiveness in the shipping industry

The present study empirically evaluates the role of human talent in the effective implementation of quality management systems in the shipping industry context. Specifically, we analyze the relationships among top management commitment to quality, ISM (International Safety Management) Code effectiveness and competitiveness as well as we assess the influence of talent in these associations. We test our research hypotheses using a sample of 199 shipping companies located in Greece. The findings show that ISM Code effectiveness acts as a mediator between top management commitment and shipping company competitiveness, while the different talent philosophies were found to moderate this relationship.
