A Comperative economical analysis on the design of berm breakwater: case study on Ordu-Giresun airport berm breakwater

Atak, Doğukan
Berm breakwaters can be alternatives to the conventional rubble mound breakwaters as they can be designed for high stability, low wave overtopping rates and economic viability. However, fully and partly reshaped berm brekwaters require optimization of design and construction parameters which requires physical model experiments. In this study, Ordu-Giresun Airport Berm Breakwater and 4 alternative crosssections of fully and partly reshaped berm breakwaters were tested for stability and wave overtopping. Analyses of all sections were executed to compare their performances. The experiments were conducted in the Coastal and Harbor Engineering Laboratory of the Middle East Technical University, Civil Engineering Department. Models were constructed using different ranges of stone sizes with a model scale of 1:32.86. It was concluded that both fully reshaped and partly reshaped cross sections can be designed to provide the specifications of the project. In the final part of study, cost analyses of the sections we re carried out using two approaches: (a) unit prices listed by the government, (b) the implementation of the contractor. It is shown that construction of the alternative berm breakwaters to Ordu Giresun Airport that ensures stability and wave overtopping conditions could be more economical.


A Comparative study on stability and overtopping performances of reshaping berm breakwaters

Berm type rubble mound breakwaters are preferred by engineers due to their relative advantages in economy and implementation compared to conventional rubble mound breakwaters. In this study, a previously constructed hardly reshaping berm breakwater protecting a filling area used as an airport between Ordu and Giresun cities in the Black Sea Region is compared to several alternative reshaping (partly or fully) models under the same stability and serviceability conditions by physical model experiments. In the...

Rubble mound breakwaters are one of the most common coastal defense structures constructed around the world. Hudson (CERC, 1977; CERC, 1984), Van der Meer (1988) and Van Gent et al (2003) are the major stability formulas that are used to find the armour stone weight of rubble mound breakwaters. In the first part, a comparative study on major stability formulas is carried out to discuss the discrepancies in application of these design formulas. A computational tool Design Armour Stone (DAS) is developed with...
An evaluation of seismic hazard and potential damage in Gaziantep, Turkey using site specific models for sources, velocity structure and building stock

Assessment of potential seismic risk and losses in urban environments is necessary for several purposes ranging from risk mitigation to city and regional planning. It is well known that loss estimation should be performed within an interdisciplinary setting involving earth sciences and engineering. Field experience from recent events worldwide shows that the spatial variability of seismic damage is due to the combined effects of earthquake source properties, local site conditions and structural characterist...
A Comparative study of cuttings transport performance of water versus polymer-based fluids in horizontal well drilling
Allahvirdizadeh, Payam; Parlaktuna, Mahmut; Kuru, Ergun; Department of Petroleum and Natural Gas Engineering (2015)
High drilling fluid circulation rate is often needed for effective transportation of cuttings in horizontal and extended reach wells, which may not be always achievable due to the risk of fracturing the rock by increased bottom hole dynamic pressure and also limit of pumps capacity. Keeping the bottom hole pressure low enough while increasing the flow rate is, therefore, a major challenge in horizontal well drilling operations. A potential solution to this problem would be to use drag reducing additives in ...
A Material Perspective on Consequence of Deformation Heating During Stamping of DP Steels
ŞİMŞİR, CANER; Cetin, B.; Efe, Mert; Davut, K.; Bayramin, B. (2017-07-06)
Recent studies showed that, during stamping of high strength steels at industrially relevant production rates, local temperature in the blank may rise up to 200°C – 300°C due to deformation heating. Moreover, die temperature may also rise up to 100°C – 150°C for progressive stamping dies. Based on the common assumption that the blank softens as the temperature increases, thermal softening creates a margin in Forming Limit Diagram (FLD) and therefore the FLD determined at room temperature can safely be used ...
