A New Theoretical Dynamic Analysis of Ship Rolling Motion Considering Navigational Parameters, Loading Conditions and Sea State Conditions
(MDPI, 2022)[Abstract] Despite the IMO’s efforts and the large quantity of research carried out over the years concerning the sudden loss of stability in fishing vessels, and even the damage done to merchant fleets due to cargo shifting, ... -
Analysis of the Pre-injection Configuration in a Marine Engine Through Several MCDM Techniques
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2021)[Abstract] The present manuscript describes a computational model employed to characterize the performance and emissions of a commercial marine diesel engine. This model analyzes several pre-injection parameters, such as ... -
Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks
(Mathematical Institute, Slovak Academy of Sciences, 2022-01-01)[Abstract] The present work proposes several pre-injection patterns to reduce nitrogen oxides in the Wärtsilä 6L 46 marine engine. A numerical model was carried out to characterise the emissions and consumption of the ... -
Application of residuals from purification of bivalve molluscs in Galician to facilitate marine ecosystem resiliency through artificial reefs with shells – One generation
(Elsevier, 2023-01-15)[Abstract] The seas and oceans of the planet provide a wide range of essential resources. However, marine ecosystems are undergoing severe degradation due to the unsustainable exploitation and consumption patterns of the ... -
Assessment of the Materials Employed in Green Artificial Reefs for the Galician Estuaries in Terms of Circular Economy
(MDPI, 2020)[Abstract] To exploit marine resources in a sustainable way, efficient management systems must be used such as green artificial reefs (GARs). These reefs are mostly made up of renewable and organic materials. When adopting ... -
Configuration Methodology for a Green Variety Reef System (AR group) Based on Hydrodynamic Criteria – Application to the Ría de Ares-Betanzos
(Elsevier, 2021-05-05)[Abstract] For the evolution and development of artificial reefs to attain the expected results, hydrodynamics is emerging as a key factor that must be taken analyzed in detail. In particular, thanks to the hydrodynamics ... -
Definition of an Artificial Reef Unit through Hydrodynamic and Structural (CFD and FEM) Models—Application to the Ares-Betanzos Estuary
(MDPI, 2022)[Abstract] The application of hydrodynamics to the definition of artificial reefs is of great interest since the positioning of the artificial reef modules on the sea floor alters the water velocity field, causing an ... -
Design and Performance Analysis of a Formulation Based on SDBS and Ionic Liquid for EOR in Carbonate Reservoirs
(Elsevier B.V., 2022-02)[Abstract] A large proportion of extant crude oil is found in carbonate reservoirs worldwide. Alkylbenzene sulfonates are inexpensive anionic surfactants but they cannot be used in these reservoirs due to their incompatibility ... -
Economic Feasibility of Floating Offshore Wind Farms Considering Near Future Wind Resources: Case Study of Iberian Coast and Bay of Biscay
