A decision-making tool for port operations based on downtime risk and met-ocean conditions including infragravity wave forecast
Costas Gómez, Raquel; Carro Fidalgo, Humberto; Figuero, A.; Peña González, Enrique; Sande, José (MDPI, 2023)[Abstract:] Port downtime leads to economic losses and reductions in safety levels. This problem is generally assessed in terms of uni-variable thresholds, despite its multidimensional nature. The aim of the present study ... -
Application of an Analytic Methodology to Estimate the Movements of Moored Vessels Based on Forecast Data
Sande, José; Figuero, A.; Tarrío-Saavedra, Javier; Peña González, Enrique; Alvarellos, Alberto; Rabuñal, Juan R. (MDPI, 2019-09)[Abstract]: A port’s operating capacity and the economic performance of its concessions are intimately related to the quality of its operational conditions. This paper presents an analytical methodology for estimating the ... -
Conversion of Vertical Slot Fishways to Deep Slot Fishways to Maintain Operation during Low Flows: Implications for Hydrodynamics
Pena Mosquera, Luis; Puertas, Jerónimo; Bermúdez, María; Cea, Luis; Peña González, Enrique (MDPI, 2018)[Abstract:] Deep slot fishways (DSF) are similar to vertical slot fishways (VSF) except that a sill has been placed at the base of the slot, and thus require a lower discharge to operate. The conversion of a VSF to a DSF, ... -
Deep Learning-Based Wave Overtopping Prediction
Alvarellos, Alberto; Figuero, A.; Rodríguez-Yáñez, Santiago; Sande, José; Peña González, Enrique; Rosa-Santos, Paulo; Rabuñal, Juan R. (MDPI, 2024-03-20)[Abstract]: This paper analyses the application of deep learning techniques for predicting wave overtopping events in port environments using sea state and weather forecasts as inputs. The study was conducted in the outer ... -
Dynamic calculation of breakwater crown walls under wave action: influence of soil mechanics and shape of the loading state
Maciñeira, Enrique; Peña González, Enrique; Sande, José; Figuero, A. (MDPI, 2019)[Abstract:] As a consequence of the action of waves on rubble mound breakwaters, there are loads—both on the vertical and horizontal sides of the crown walls—which modify the conditions of their stability. These loads ... -
Dynamical Study of a Moored Vessel Using Computer Vision
Figuero, A.; Rodríguez, Álvaro; Peña González, Enrique; Sande, José; Rabuñal, Juan R. (Springer, 2018)[Abstract]: Wind and wave effects have a major impact on the design of mooring and anchoring systems, whose purpose is to prevent the movement of the cargo and the moored ship while optimizing the operations which have to ... -
Editorial—Physical Modelling in Hydraulics Engineering
Peña González, Enrique; Anta, Jose (MDPI, 2021)[Abstract] Note: In lieu of an abstract, this is an excerpt from the first page: Laboratory experiments and field works play a crucial role in hydraulic research, development, and design as many hydraulic processes elude ... -
Field measurements of angular motions of a vessel at berth: Inertial device application
Figuero, A.; Rodriguez, Alvaro; Peña González, Enrique; Rabuñal, Juan R. (Romanian Soc Control Tech Informatics, 2018)[Abstract]: The study and characterization of the oscillations of a moored vessel has a major importance in port operational efficiency, not only in the design of mooring and anchoring systems, but also in order to prevent ... -
Integrated Approach to Assess Resonance Between Basin Eigenmodes and Moored Ship Motions With Wavelet Transform Analysis and Proposal of Operational Thresholds
Costas Gómez, Raquel; Figuero, A.; Peña González, Enrique; Sande, José; Santos, P. Rosa (Elsevier, 2022)[Abstract] Waves with periods between 25 s and some minutes can amplify the motions of moored ships, which may result in terminal downtimes and compromise safety. The purpose of this work is twofold: (i) studying infragravity ... -
Machine Learning Based Moored Ship Movement Prediction
Alvarellos, Alberto; Figuero, A.; Carro Fidalgo, Humberto; Costas Gómez, Raquel; Sande, José; Guerra, Andrés; Peña González, Enrique; Rabuñal, Juan R. (MDPI, 2021)[Abstract] Several port authorities are involved in the R+D+i projects for developing port management decision-making tools. We recorded the movements of 46 ships in the Outer Port of Punta Langosteira (A Coruña, Spain) ... -
The influence of infragravity waves, wind, and basin resonance on vessel movements and related downtime at the Outer Port of Punta Langosteira, Spain
Costas Gómez, Raquel; Figuero, A.; Sande, José; Peña González, Enrique; Guerra, Andrés (Elsevier, 2022)[Abstract:] The coupling of low-frequency oscillatory modes of a harbor with horizontal motions of moored ships can amplify the latter, causing operational and safety problems. The objectives of this study were to analyze ... -
Two-Dimensional Dam-Break Flood Analysis in Data-Scarce Regions: The Case Study of Chipembe Dam, Mozambique
Álvarez, Manuel; Puertas, Jerónimo; Peña González, Enrique; Bermúdez, María (MDPI AG, 2017)[Abstract:] This paper presents the results of a modeling study of the hypothetical dam break of Chipembe dam in Mozambique. The modeling approach is based on the software Iber, a freely available dam break and two-dimensional ...
