NOOR III SOLAR TOWER


Uarzazate, Morocco

The NOOR III phase of the Uarzazate Solar Power Station (Morocco) consists of a 250m tall central solar tower surrounded by a park of reflectors. Slender cylindrical structures, such as the NOOR III tower, are usually dynamically sensitive to wind and require special consideration.

Oritia & Boreas performed a full aeroelastic wind tunnel study of the central tower to determine the wind induced structural loading for design, along with an analysis of the aeroelastic stability of the tower up to and beyond maximum wind speeds expected at the site.

TUNED MASS DAMPER (TMD) ALMONTE RIVER BRIDGE

Cáceres, España

This study is a continuation of O&B involvement throughout the design and construction of the high-speed rail bridge crossing the Almonte River.

In this project, Oritia & Boreas collaborated with the constructor for assessing the design performance characteristics of a prototype TMD which was to be installed on the provisional cables used in the construction of the 350m arched span.

O&B designed and constructed a purpose built test-bench for capturing the response of the TMD to harmonic excitation, leading to an assessment of the TMD effective damping and design recommendations.

 

HISGAURA BRIDGE

Santander-Boyaca, Colombia

The 420m cable-stayed bridge is located at the border between the Santander and Báyaca departments, Colombia. The bridge crosses a valley of some 130m and is surrounded by relatively complex topography from all sides.

Section model tests were performed in the wind tunnel for assessing the equivalent static design loads and analysis of the aerodynamic stability.

HONDA BRIDGE

Tolima, Colombia

The Honda Bridge is located in the Tolima department of Colombia, crossing the Magdalena River. The central span of the cable-stayed bridge is 250m.

Oritia & Boreas investigated the aerodynamic stability and reported the equivalent static design loads of the bridge based on section model tests in the wind tunnel.

“ALGECIRAS SAFEPORT” METEO-OCEANIC RISK MANAGEMENT IN HARBOUR ENVIRONMENTS - PHASE I

Cádiz. Spain.

O&B was leader in an R&D project for developing a set of guidelines towards certifying the Harbour Meteorological-Ocean Risk Management System. The study was completed in partnership with the Environmental Hydraulics Institute of University of Cantabria (IH Cantabria); and the Harbour Research Laboratory (HRL) of the Polytechnic University of Madrid.


The project included the expansion of the ocean-meteorological monitoring network (wind, waves, agitation and currents) of the Algeciras Port Authority; development of wind/wave predictive modelling systems; a user orientated website of real-time publication of environmental data to aid in decision-making

WIND TUNNEL STUDY ON AERODYNAMIC OPTIMIZATION OF BRIDGE RAILINGS

 Constitution Bridge, Cadiz.

At deck height the cable-stayed bridge is exposed to relatively strong Atlantic winds, giving extra importance in the aerodynamic design of the lateral windshield railings.

Wind tunnel tests were performed on a large-scale section model to measure the static force coefficients on the railing system, combined with modal finite element analysis for providing wind loading and design recommendations.

FULL AEROELASTIC WIND TUNNEL STUDY OF CONSTITUTION BRIDGE


Cádiz, Spain.

Constitution Bridge is the longest and highest span cable-stayed bridge in Spain and the third largest in Europe, with a total length of 3082m, main span of 540m and deck height of 69m.

A full aeroelastic wind tunnel study was performed to examine the dynamic response and aerodynamic stability of the completed bridge, and to identify wind speeds associated to possible flutter instability and vortex shedding induced oscillations.

 

 


WIND TUNNEL STUDY OF TORRE CASTELLANA 77, MADRID


Madrid, Spain.

An additional four levels were added to an existing 97m tower located in the centre of Madrid (Paseo de la Castellana Nº77).

Pressure model tests were performed in the boundary layer wind tunnel for defining the structural loading distribution on the updated building design.

 


ENVIRONMENTAL MONITORING ON AN OFFSHORE SEAWALL


Algeciras Port Authority, Spain.

Expansion of the Algeciras Port Authority (APBA) environmental monitoring network with the installation of meteorological sensors on the Isla Verde offshore seawall.

Oritia & Boreas were responsible for the design, installation and maintenance of the new stations for real-time publication on the APBA and national port authority websites.
