: Exhaust gas emissions from ships are an aspect of the global maritime industry which has been given great importance in recent years. Increasing the efficiency of maritime transport regarding fuel consumption and exhaust gas emissions is an ongoing effort which requires a detailed analysis of all ship systems that have an effect on the aforementioned issue. One aspect that can be analyzed in this regard are the various machinery faults which influence the ships exploitation efficiency. This paper will focus on the analysis of the two stroke slow speed diesel main engine with early and late fuel injection faults. This analysis is based on a set of data acquired from a simulation model of a LCC tanker vessel including fuel consumption and emission pollutants such as carbon monoxide (CO), sulphur oxides (SO X ) and carbon dioxide (CO 2 ) as a greenhouse gas with early and late fuel injection fault introduced to different number of main engine cylinders. This methodology of research has the advantage of analyzing various scenarios which are not as easily reproduced on actual vessels.

: This is a statistic study on the perceived quality of safety training. The study is based on respondents from the Swedish register of seafarers. The results show that the experience of safety training is generally positive among the seafarers. The level of positivity is influenced by personal circumstances (such as onboard position and age) and by external factors in the work environment (such as ship type, trade area and flag state). However, the effect of onboard position diminishes when age and external factors are controlled for. In this situa tion, only the positive effects for cabin crew and age remain with strength and significance. Most ship types show strong positive effect, except for road ferries and vessels for max 12 passengers. When it comes to trade area it is only sheltered trade tha t shows a significant positive effect. Moreover, a h omeland flag in the stern leads to a significant increase in the perceived quality of the safety training. These findings are discussed in the concluding part of the paper

: Ship maneuvering is a complex operation with inherent uncertaintie s. To express this complexity in system performance during the navigation process, an analysis model has been developed using Functional Resonance Analysis Method (FRAM) and Dynamic Bayesian Network (DBN). The functional level of dynamic work onboard is assessed and modeled using FRAM qualitatively, in which a key function and the function’s potential coupling for specific instantiation are identified. Further analysis is done by integrating the FRAM analysi s with DBN for quantification. The evolution of sy stem performance over time is determined through changes in the probability of function’s mode, namely strategic, tactical opportunistic, and scrambled. The model presented in this study concerns the fluctuation of ship officer performance to overcome the obstacles during the encounter event. As a result, the integration of FRAM-DBN shows promising usability to evaluate human performance. The essence of human adaptive capacity is also highlighted through system resilience potency, that is, the potency to le arn, respond, monitor, and anticipate. We also discuss how this finding contributes to enhance safety analysis, in specific, to provide explicit representation of the dynamic in human performance in ship navigation based on Safety-II idea.

: At the core of the shipping enterprise is the competence of the crew of the ships. For this reason, the international community (particularly as represented by the International Maritime Organization (IMO)) has always endeavoured to ensure that seafarer education and training is as optimal as can be achiev ed by the glo bal community of nations. A variety of elements are normally associated wit h such education and training. They include educational elements conducted ashore in maritime education and training institutions (classroom-based lectures, laboratory exercises and simulators, for example) as well as training conducted on board a ship in service. It has been well recognised that one of the most effective means of practical training for seafarers is the training conducted on board ships, so-called “onboard training”. There is, however, a wide range of approaches taken by different jurisdictions in their application of specific strategies for onboard training. The approaches may differ in timing (at what stage of the educational process onboard training is conducted) a nd duration (how long the training is carried out), for example. These diff erences exist even though onboard training itself may be argued to universally derive its primary philosophical basis from the learning theories of situated learning and cognitive apprenticeship. To identify the rationale and factors informing different approaches to the implementation of onboard training from a theoretical perspective (establish a theoretical framework), and thereby to set the stage for the interrogation of how thes e approaches will address the challenges of the future (arising, for exampl e, from the acceleration of technologically-mediated education and training), it is necessary to, first of all, examine how apprenticeship and on -the-job training have been perceived in the theoretical literature inside or outside the maritime domain and h ow the different approaches are informed by these theories. This paper, therefore, employed a systematic literature review to identify the theoretical foundation of on-the-job training and apprenticeship.

: This paper aims to cover a gap in maritime literature by analysing the performance of the international fleet through the BIMCO Shipping KPI System databases, and by highlighting the necessity for the adoption of Global Performance Indicators to serve the needs of a sustainable maritime industry. The paper investigates the complex interrelations of the various types of performance in shipping, consisting of 57,622 ships of all commercial types, operated from 26 countries, covering the environmental, health, safety management, HR management, navigational safety, operational, security, and technical performance. Results indicate that countries rank differently with regards to the aggregated performance of their respective shipping companies, signifying different managerial approaches. This paper contributes to the discourse of maritime governance, aiming to be of interest to all maritime stakeholders dealing with marine policies and institutional arrangements for the management and regulation of international shipping.
