Generation of H₂ on Board Lng Vessels for Consumption in the Propulsion System
(Sciendo, 2020)[Abstract] At present, LNG vessels without reliquefaction plants consume the BOG (boil-off gas) in their engines and the excess is burned in the gas combustion unit without recovering any of its energy content. Excess BOG ... -
Heat stress on board : risk and prevention
(Universitat Politècnica de Catalunya. Departament de Ciència i Enginyeria Nàutiques, 2020)[Abstract] The heat stress is the load of heat that a worker receives and accumulates in his body and that result of the interaction between the environmental conditions of the place where he works, the physical activity ... -
HTR-Based Power Plants’ Performance Analysis Applied on Conventional Combined Cycles
(Hindawi-Wiley, 2015)[Abstract] In high temperature reactors including gas cooled fast reactors and gas turbine modular helium reactors (GT-MHR) specifically designed to operate as power plant heat sources, efficiency enhancement at effective ... -
International regulations on labour health and safety applied to fishing and maritime transport sectors. Are maritime workers under-protected?
(Via Medica Journals, 2012)[Abstract] The work activity developed on board is of great importance in our nearby environment, and it has a series of peculiarities that determine the service rendering of sea workers. On the other hand, work at sea is ... -
Internet of Things in Energy-Sensitive Processes: Application in a Refrigerated Warehouse
(IEEE, 2024-05-29)[Abstract]: This article aims to address an existing research gap in the study of the most widely used mathematical procedures in the field of automatic control of energy-sensitive industrial processes. In these types of ... -
Investigación sobre técnicas docentes para marinos: Simuladores de sala de máquinas
(REDINE, Red de Investigación e Innovación Educativa,, 2020)[Resumen] En el año 2017 se inicio uno de los grupos de innovación educativa que, a nivel internacional, han llamado la atención por parte de las escuelas de Náutica y Máquinas. Dicho grupo de innovación se centra en la ... -
Legal gaps relating to labour safety and health in the maritime transport sector in Spain
(Via Medica Journals, 2011)[Abstract] Nowadays the labour sector is experiencing an important increase in the application of risk prevention policies. Although these policies are very significant due to their repercussions in the health of workers, ... -
Life cycle assessment of radioactive materials from a residential neighbourhood
(Elsevier, 2022)[Abstract] This study was carried out, with the as main purpose to evaluate the impacts of the energy mix on the radioactive material generated by a residential neighbourhood. To achieve this objective, the same neighbourhood ... -
Life Cycle Assessment of Waste Products of a Green‑Neighbourhood
(Springer, 2022)[Abstract] This research aims to quantify and to compare the effect of the energy mix of 150 countries on the waste products generated by an eco-neighbourhood. To perform this comparison, the same neighbourhood design is ... -
Methodological Design Optimization of a Marine LNG Internal Combustion Gas Engine to Burn Alternative Fuels
(MDPI, 2023)[Abstract] Marine emission policies are becoming more demanding; thus, ship propulsion and power generation technologies need to be adapted to current scenarios. LNG is already considered to be a transition fuel, and new ... -
New Climatic Indicators for Improving Urban Sprawl: A Case Study of Tehran City
(Multidisciplinary Digital Publishing Institute, 2013)In the modern world, the fine balance and delicate relationship between human society and the environment in which we exist has been affected by the phenomena of urbanisation and urban development. Today, various environmental ... -
New Tendencies in Wind Energy Operation and Maintenance
(MDPI, 2021)[Abstract] Both the reduction in operating and maintenance (O&M) costs and improved reliability have become top priorities in wind turbine maintenance strategies. O&M costs typically account for 20% to 25% of the total ... -
Noise Exposure and Mitigation on High-Speed Craft: Assessing Acoustic Environment and Regulatory Compliance
(MDPI, 2024)[Abstract] High-speed craft (HSC) present unique challenges regarding on-board noise levels, affecting crew safety, comfort, and operational efficiency. This study investigates noise exposure and mitigation strategies ... -
Novel Modeling for the Calculation of the Center of Lateral Resistance Position of Different Ships Making Use of a Full Mission Bridge Simulator and AI Tools
(MDPI, 2024)[Abstract] Ship maneuvering in ports is increasingly reduced because the increase in ship size is not proportional to the increase in port areas. Furthermore, the number of assisted vessels and the need for tugboats working ... -
On board LNG reliquefaction technology: a comparative study
(Walter de Gruyter, 2014)[Abstract] Reliquefaction technologies are being currently applied on board liquefied natural gas (LNG) carriers on the basis of economic criteria and energy efficiency. A variety of reliquefaction techniques have been ... -
Optimization of Ship’s Navigational Parameters to Improve the Stowage and Securing Criteria of Non-Standardized Cargo in Ships
(MDPI, 2023)[Abstract] General cargo ships are the most numerous in the merchant fleet. In these vessels, the stowage and securing of non-standardized cargo must be designed prior to being shipped. Furthermore, during sea navigation, ... -
Photovoltaic Power Prediction Using Artificial Neural Networks and Numerical Weather Data
(MDPI, 2020)[Abstract] The monitoring of power generation installations is key for modelling and predicting their future behaviour. Many renewable energy generation systems, such as photovoltaic panels and wind turbines, strongly ... -
Prediction of daily global solar radiation and air temperature using six machine learning algorithms; a case of 27 European countries
(Elsevier, 2022)[Abstract] The prediction of global solar radiation in a region is of great importance as it provides investors and politicians with more detailed knowledge about the solar resource of that region, which can be very ... -
Primary conversion in non-resonant wave energy converter with floating buoy
(Universidad de Catabria, Spanish Society of Maritime Research (SEECMAR), 2019)[Abstract] This paper studies one of the technical problems that occur in the process of moving from ”waves toelectricity” in floating wave buoys converters located near the coast: to maximize the product force bydisplacement. ... -
Proposal of a New Control System Making Use of AI Tools to Predict a Ship’s Behaviour When Approaching the Synchronism Phenomenon
(MDPI, 2024)[Abstract] In spite of the IMO’s efforts to improve the safety of intact stability on ships, synchronous rolling still causes large rolling angles, resulting in a very dangerous situation on board. The implementation of ...
