: Marine transportation is a critical component of global trade and commerce, with ports serving as key nodes for the movement of goods and people. However, navigating these ports can be hazardous, with the potential for accidents and incidents that can lead to loss of life, environmental damage, and economic disruption. This study investigates the impact of socioeconomic factors on the operational risk assessments and adoption of innovative navigational aids for better safety among marine pilots in Lagos ports. A mixed-methods approach is employed, combining surveys and in terviews to collect data from a sample of marine pilots operating in Lagos ports. The study focuses on the decision-making process of marine pilots in high-risk environments, exploring how factors such as education level, incom e, and experience might influence their risk assessments and willingness to adopt new technologies. The study's findings have important implications for policies and programs aimed at promoting safer navigation practices in Lagos ports and improving the overall safety of marine operations. The results can also inform the design of training and education programs for marine pilots, as well as the development of new technologies and tools to support safe navigation.

: The current spill response capability in Finland is built to respond to oil spills caused by heavy fuel oils and the most transported oil cargoes. However, the implementation of the Sulphur Directive in 2015 changed the fuel profiles of the ships: prior to the new regulation ships operating in the Baltic Sea mainly used heavy fuel oil (HFO), whereas now ships use marine gas oil (MGO DMA) or marine diesel (MDO DMB) known as marine distillate fuels. This paper reviews the effectiveness of the current recovery techniques in responding to spills of marine distillate fuels based on the oil recovery field tests. The results indicate that conventional recovery techniques are only partially applicable to marine distillate fuels, which calls for a reassessment of the marine oil spill response capability and further research. The use and availability of low ‐ carbon marine fuels will continue to increase as emission regulations become more stringent. This will require a continuous assessment of the oil recovery capabilities and the adaptation of spill response preparedness accordingly.

: The transition from conventionally manned to autonomous ships is accompanied by the development of enhanced Decision Support Systems (DSS) for navigators. Such systems need to consider interactions among hardware, software, and humans and their potential effects on system performance, which require rigorous testing to verify the system ʹ s safe decision ‐ making ability and operational limits. Testing requirements for verification are aimed at 1) assessing the system ʹ s reliability and failure handling performance, and 2) integration testing. This work uses the System ‐ Theoretic Process Analysis (STPA) to develop integration tests for a novel DSS. STPA is a structured methodology to identify hazards from multiple sources, including hardware or software failures, system interactions, and human errors. The objectives of the study are to develop and assess the feasibility of integration test procedures based on STPA. The stability monitoring subsystem from the DSS is analyzed as a case study. The results are used to suggest functional and performance integration test procedures.

: In recent years, 'weather routing' ha s been attracting increasing attention as a means of reducing costs and environmental impact. In order to achieve high- quality weather routing, it is important to accurately predict the ship's speed through ground during a voyage from ship control variables and predicted data on weather and sea conditions. B ecause sea condition forecasts are difficult to produce in-house, external data is often used, but there is a problem that the accuracy of sea condition forecasts is not sufficient and it is impossible to improve the accuracy of the forecasts because the d ata is external. In this study, we propose a machine learning method for predicting speed through ground by considering the actual values of the previous voyage’s drift speed for ships that regularly ope rate on the same route, such as ferries. Experimental results showed that this method improves the prediction performance of ship’s speed through ground.

: This article focuses on issues related to risk assessment when maneuvering a loaded bulk carrier in close proximity to a vessel performing underwater work at the time. It is based on a detailed analysis of an incident that took place in the Gulf of Gdansk. The write -up explains real turns of events, conditions and factors that contributed to the incident, but also its consequences are explained. Some other aspects of this article focuses on, are the processes of examination of the direct causes of the incident and identification not compliance with regulations, requirements, or procedures that help to find out the human, technical, and organizational errors. The authors of this text indicate the safety guards that have failed, give the reasons for their fail ure and, where it was possible, point out the safety guards that should or must be established . The article does not take into account theoretical models for the described accidents, but only practical aspects, human errors and applicable local and interna tional laws and regulations. Particular attention was devoted to the analysis of human errors made by officers maneuvering the surface vessel in the close vicinity of divers perfo rming underwater works.
