The work integrates the human error term in the broader concept of human performance analysis. The main issues associated with human error and human reliability are highlighted step by step, resulting from the review of literature, from the perspective of the relationship between risk and safety. To assess the risks arising from human error and to reduce vulnerability of work, methods derived from the probabilistic assessment of the work safety systems are used. To identify the risks caused by the human error, the authors propose the Fault Tree Analysis (FTA) method. The paper reveals the way the method is used for identifying the critical subsystems for the functioning of a given system and analyzes how unwanted events and their causes arise and occur. Also, a case study that is investigated throuhg the FTA method and that consists in the analysis of an accident that occurred in Evangelos Florakis naval logistics base from Cyprus, is presented.

The subject of this paper is to analyze the hydrometeorological parameters received on board during on route from Singapore to Santos (Brazil) between July 15th and August 4th, 2018 to optimize fuel consumption on board. The information was obtained daily, in real time, using on-board measurement tools and SPOS 8 Software provided by MeteoGroup, and those related to fuel consumption in the EcoVoyage program. General analyzes of hydrometeorological parameters were introduced as graphs, with more detailed values extracted from MSPS (Maersk Ship Performance System).

The purpose of this paper is to analyze the advantages of adjusting the navigational routes not only based on geographical hazards but also according to hydro-meteorological parameters with the purpose of creating a route with maximum efficiency. The Ship Performance Optimization System (SPOS) used by vessels is one of the best onboard weather routing systems. In a competitive market such as the one today, it is essential to use such software so that the ship's route can be optimized, taking into account sea conditions such as waves, current and swell, wind and other weather elements. Other benefits include a decreased risk of environmental pollution caused by ships unprepared for certain adverse weather conditions.
