Abstract

Given the large number of recent terror attacks worldwide, there is a growing concern over the security issue in the maritime world. Aim of this paper is to address a scenario pertinent to the maritime security problem using the evacuation simulation software tool EVI. The vessel chosen for this case study is a 13-deck cruise ship. The scenario investigated deals with the evacuation of a large density populated area within the vessel, where an explosive device has been placed and assesses the potential loss of life, according to the distance of the agents relative to the explosion blast. Three different positions of the explosive device are examined in this study and for each position six different cases are examined, in which the effect of prior warning to the explosion is taken into consideration. In the first case, the explosion takes place at the beginning of the simulation (t=0) in order to replicate such a scenario in which those agents within the restaurant are un-alerted to the presence of the explosive device. In the rest of the cases the explosion takes place after warning times of 0.5, 1, 1.5, 2 and 2.5 minutes respectively in order to assess the sensitivity of the fatality rate and evacuation to prior warning time.

Abstract

Maritime transport has been striving to reduce ship accidents since its origins, which results in loss of lives or"br" properties and damage for the environment. Hence, a continuous effort to enhance safety is a crucial requirement"br" for the maritime sector, for which several approaches have been tried for the past years. This paper presents the"br" first results of a study which aim is to assess the factors affecting collision accidents in order to enhance safety and"br" resilience. This aim is achieved by using Fuzzy Cognitive Maps (FCMs) method, which consider and evaluates"br" importance of these factor by calculating and assigning individual weights to them. Moreover, FCM appears to be"br" a suitable approach since it can take into account both, fuzzy data and past accidents experiences. Hence, in this"br" paper with the help of FCM, past accidents from the Marine Accident Investigation Branch (MAIB) database"br" regarding collision are analysed to identify the contributors of collision accidents and their FCM weightings.

Abstract

In a global competitive world, the education progress from school to University and the continuous professional training is the key to enhance productivity, employability and social stability. Continuous education is a key issue for the evolution of human being, not only in the professional sector of life but also in the personal life, enhancing important elements of the character and personality for each individual. Furthermore, new technologies, regulations and policies in maritime industry reveal the necessity for additional educational schemes that will cover the market needs. Considering the growing challenges of port, shipping and logistics, TrainMoS II and On The MoS Way Network (OTMW-N) European projects aimed to the development of students and professionals skills and laid the foundations for a cross-European maritime educational system. TrainMoS II was the evolution of the TrainMoS project, improving the tools developed during the first phase and covering a whole new range of technical and operational topics, including alternative fuels and technologies, logistic issues (including Single Window Directive 65/2010), damage control (incl. IMO ‘Safe Return to Port’ concept) and evacuation/crisis management operations. TrainMoS II focused on the provision of professional training and vocational education activities to undergraduates and professionals who belong to different sectors in the multimodal transport chain. Individual Modules were open to attendance from students to require a Continuous Professional Development (CPD) certification. At the same time, OTMW-N covered the training needs in the use of alternative fuels in marine industry, such as LNG. OTMW-N was also offering professional training and vocational education through a series of activities in which students obtain the opportunity to enhance their academic background and to implement it in simulation programmes. The present paper presents the results and the contribution of these projects to the maritime community. Stakeholder needs from different sectors of maritime industry are examined and the outcomes of the aforementioned projects are presented and discussed. Document type: Conference object

Abstract

The correlated exploitation of heterogeneous data sources offering very large historical as well as streaming data is important to increasing the accuracy of computations when analysing and predicting future states of moving entities. This is particularly critical in the maritime domain, where online tracking, early recognition of events, and real-time forecast of anticipated trajectories of vessels are crucial to safety and operations at sea. The objective of this paper is to review current research challenges and trends tied to the integration, management, analysis, and visualization of objects moving at sea as well as a few suggestions for a successful development of maritime forecasting and decision-support systems.

Abstract

The fluctuation of fuel price levels, along with the continuous endeavour of the shipping industry for economic growth and profits has led the shipbuilding industry to explore new designs for various types of merchant ships. Moreover, the introduction of new regulations by the IMO has added further constraints to the ship design process. In this respect, proper use of modern CAD/CAE systems extends the design space, while generating competitive designs in short lead time. This study deals with the parametric design and holistic optimisation of a post-panamax containership. The methodology includes a complete parametric model of a containership’s external and internal geometry, as well as the development and coding of all tools required for the determination of both the design constraints and the efficiency indicators, which are used for evaluating the parametrically generated designs. The second-generation intact stability criteria are taken into consideration in the optimisation process. The set-up multi-objective optimisation problem is solved by use of the genetic algorithms and clear Pareto fronts are generated. Document type: Conference object

Abstract

This paper presents a brief summary of the work conducted by the MSRC at Strathclyde University in which the"br" effect of operational location on the estimation of a vessel’s survival probability has been investigated and new sfactor"br" formulations proposed. Further work is presented in which updated accident wave statistics have been used"br" in order to assess the impact of vessel specific data on the predicted survivability. A test case on a large container"br" ship has been conducted in order to gauge the effect of the new s-factor formula on the Attained Subdivision Index"br" and thus the vessel safety level with regards to collision damage.

Abstract

integrity management (AIM) is crucial at each stage of offshore energy development in order to maintain the integrity and enhance the safety of critical assets. Risk-based integrity is a widely used approach in AIM which aims to assess the potential risks of infrastructure damage, on the basis of likelihood of failure and magnitude of consequences. This paper develops a risk-based integrity model for offshore energy infrastructures with particular application to subsea oil and gas pipelines. The likelihood of failure is estimated using the Bayesian prior-posterior analysis as well as expert elicitation methods. The consequences associated with failures are also evaluated in terms of a 'cost' function which includes the costs of inspection, maintenance and repair. Our presented model is then applied to assess the potential risk of damage to an oil export pipeline. The results indicate that 'corrosion' is the most common cause of failure for pipelines, followed by external influences and human and operational errors. In accordance with the consequence analysis carried out, cost of inspection and preventive maintenance is evaluated to be significantly less than the costs associated with pipeline replacement. Finally, three mitigation strategies are suggested to minimise the risks of pipeline damage.

Abstract

When production facilities reach the end of their economic life in the offshore oil and gas industry, field owners must decide whether to replace, extend the life of, or decommission assets. The decommissioning of deep and ultra-deep water oil and gas pipelines has become a serious issue in recent years because it is a complex process and presents challenges to stakeholders. In this paper, we review the current practices of pipeline decommissioning in different regions of the world and then highlight issues and challenges related to such activities in deep and ultra-deep waters. These issues and challenges can be broadly categorised into technical (e.g., selection of appropriate decommissioning procedures for handling hazardous pipelines), financial or economic, health and safety legislation, environmental, and human or organisational issues (such as lack of requisite skills, knowledge and expertise). In order to address the challenges identified in the study, some directions for future research are suggested. [Received: December 7, 2016; Accepted: October 17, 2017]

Abstract

This article summarises related work undertaken by the EC-funded Research Project TARGETS, which focuses on assessing energy efficiency by a direct approach. Energy flows onboard ships are considered in the time domain for complete ship energy systems simulation, allowing for interactions at system and component levels and accounting for different configurations, operating profiles, itineraries and environmental conditions. The approach and tools form the basis for life-cycle energy management considerations, addressing design, operation and retrofitting. To demonstrate the methodology leading to the evaluation of performance-based energy efficiency and its anticipated impact on ship design and operation, a case study for containership was carried out. Results are presented and discussed, demonstrating considerable advantage in adopting a more systematic and scientific approach to address Energy Efficiency of ships. Document type: Article
