Ensuring that port development does not compromise the integrity of the environment and instead fosters sustainable growth is of paramount importance. Recently green technologies conceders as important tool that support port sustainability and development. Design/Methodology/Approach: This study examines the deployment and influence of green technologies on port sustainability, using a quantitative analysis of survey responses collected among a varied array of stakeholders across Egyptian ports, survey questions verify green technology application, evaluate environmental consequences, operational costs, competitiveness, and obstacles, enhancing quantitative analysis with qualitative research insights; coupled with a detailed qualitative case study of the Port of Rotterdam, a port internationally known for its effective use of green technologies. The analysis underscores the transformative capacity of green technologies in attaining notable environmental improvements and enduring cost efficiencies, notwithstanding the challenges associated with initial investment hurdles. Findings: Drawing insights from the experiences of the Port of Rotterdam, the study brings to light the obstacles of intricate regulations and technological constraints, accentuating the need for simplified policy measures, consistent innovation, and an accommodating infrastructure. The study encourages a comprehensive strategy, dynamic stakeholder cooperation, and stringent scrutiny for the effective integration of eco-friendly technologies, offering valuable perspectives that can steer Egyptian ports and the broader maritime sector towards an ecologically sustainable future.

A general overview of the various analytical models and methodologies was given, outlining the key concepts behind each category, and choosing the HFACS-MA spell out to serve as a starting point for any research in this field. This particular model is a qualitative analytic model that examines both active and latent failures revealed in maritime accident reports. In this paper, a comparative study is presented among three versions of the HFACS-MA model; a benchmarking was made with a US government DoD-HFACS version in order to compare the codes inside each version to ensure the integration of all safety standards. Accordingly, the most suitable version was singled out. Design/Methodology/Approach : The modified Maritime Human Factors Analysis and Classification System (HFACS-MA) was carefully examined as a qualitative analytic model to evaluate active and latent failures stated in the contact accident report, identifying human error as the primary cause. This was done as an example of how the modified (HFACS-MA) may be applied to maritime accident analysis. Findings : The authors modified the HFACS-MA version developed by Kim et al. (2011) that was examined by Kang (2017b), and added one code to it, that is Equipment Design and Specification, code (i.9).

{"title":"Real Time Kinematic (RTK) heave as a replacement of Motion Reference Unit (MRU) heave in hydrographic surveying works","authors":"Mohammed Elmeligy, Saad Mesbah, Mohamed Mohasseb","doi":"10.21622/mrt.2023.02.1.070","DOIUrl":"https://doi.org/10.21622/mrt.2023.02.1.070","url":null,"abstract":"Heave is one of the major contributors to errors in water depth measurements. Motion Reference Unit (MRU) measures the heave signal with high-level accuracy as well as other ship motions. Unfortunately, MRU has been reported to have some of drawbacks such as; heave drift error, influence of ship motion dynamic, In addition to its very expensive price Real-Time Kinematic (RTK) GPS uses dual frequency receiver and carrier phase differential technique under kinematic solution and provides very accurate position in all three components in real time. In addition, RTK GPS also calculates the low frequency changes in water level such as tidal oscillation. This research is an attempt to investigate the possibility of using the RTK GPS data to deduce the heave signal from the GPS height (tides - heave) instead of heave from MRU to correct the water depth. Moreover, to examine to what extent, RTK heave can be used as a backup to satisfy the International Hydrographic Organization (IHO) survey order standards. A comparison between the extracted RTK heave and MRU heave signals revealed a good agreement with a strong direct correlation of 0.96. As shown in figure 1 RTK heave as a replacement for MRU heave in hydrographic surveying was statistically validated with the use of a lot of methods of analysis such as Test of the Normality, Paired Samples T Test, Wilcoxon Signed Ranks Test, Heave Signals Frequency Adjustment , Descriptive Statistics for the Two Heave Signals , Descriptive Statistics for Each Signal Individually , Correlation and Trend, Analysis Between the Two Signals, Scatter Diagram and Trend, Standard Deviation and Uncertainty for Soundings, Characteristics of the Difference between Two Signals , Comparing the Surfaces by TIN Model. The results of this analysis provided the possibility of using RTK heave as a replacement for MRU heave in hydrographic surveying. Therefore, RTK GPS is not only used to provide precise position or tidal oscillations but also based on this study, can be used to measure heave accurately to correct the depth satisfying IHO survey standards.
