Spanish engineers design a new model of slope marine dock

01.07.2008
It prevents docks from breaking in the face of heavy swell

Scientists from the UGR have designed a new “model” of slope marine docks, more resistant and prepared to reduce risks for ports, promenades or beaches, as well as the costs derived from their maintenance and repair. The design minimizes the risk of breaking of slope docks as they are more resistant against swell energy.

Marine docks construction has traditionally encountered problems derived from swell-produced breking, especially in the event of great storms. The economic spending to repair the damage is very high and it affects ports, promenades or beaches. The most recent case in Spain was the storm of March 2008, which caused considerable material damage in the coasts of the Bay of Biscay.

A new design will permit to build slope marine docks with less risk of damage, in order to reduce the costs of construction, maintenance and upkeep of such maritime structures.

“We have designated this new structure ‘S”, says María Clavero Gilabert, a member of the Group of Dynamics of Environmental Flows in the Andalusian Centre for Environmetal Studies (CEAMA-University of Granada, Spain), supervised by Dr. Miguel Losada Rodríguez.

According to the researcher, this study “is focused on the optimization of the typology of slope marine docks in order to lessen their main damage, the extraction of pieces from the external layer (loss of the blocks which Project the dock against swell).

At present, these structures have been designed in such a way that there may be serious damage in case swell grows stronger than that predicted in the design. Thanks to the results of this work, it is possible to design slope docks which remain absolutely steady up to the design swell and, in case of stronger swell, it i sable to adapt and therefore they do not suffer this problem”. It is possible for docks to reduce swell energy without breaking, with the consequent benefit for the areas to be protected.

Swell Canal

The research work to improve maritime structures has been developed from the tests carried out in the Swell Canal of the CEAMA. It was necessary to “construct slope docks to scale with homogeneous pieces of concrete cubes and carry out tests with incident swells and growing waves, so that the dock became distorted until a balance or stable profile for such wave height was reached”, says María Clavero.

The Swell-Current Canal of the CEAMA, which allows to carry out experiments on a large scale, is one of the most important in Spain; it is 23 metres long, cashiers are one meter high and it is 0.65 metres wide. This “laboratory” has been used quite often and allows to carry out the tests of the research groups specialized in Mechanics of Structures and Hydraulic Engineering. Such tests have been applied to research and technological development agreements with the port authorities of Gijón, the Bay of Cadiz, Almería-Motril, the State Coastal Office of the Spanish Ministry of the Environment, companies such as Consultoría Ibérica de Estudios e Ingeniería S.A, Dragados S.A. or EGMASA, etc.

The study by Clavero Gilabert has been funded by the Spanish Ministry of Education and Science and has been carried out in the last five years. Different papers in International conferences have been fruit of this research; one might mention the 29th and 30th International Conference on Coastal Engineering held in Lisbon -2004- and San Diego -2006-, respectively).

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
