Volume 4, Issue 2 , June 2014, Pages 57-64

  This study aims to examine the performance of the rock materials in the protective layer of rubble-mound breakwaters in southern Iran, from Rostami Port in Bushehr Province to Beris Port in Sistan and Baluchestan Province. Field inspections were carried out on a great number of rubble-mound breakwaters ...  Read More

Effect of environmental parameters on the amount of scour in marine structures

M. Arabi; F. Azarsina

Volume 4, Issue 2 , June 2014, Pages 65-76

  Scour is a phenomenon that occurs as a result of natural erosion by ground water flow and transport of seabed material. In this research, scour around the legs of marine structures is simulated using the FLOW3D.V.9.3™ commercial software. The general scour model consists of two components, namely, ...  Read More

Seismic Behavior of Jacket Offshore Platform Subjected to Near and Far Field Ground Motions

K. Kashizadeh; A. Sarvghad Moghadam; F. Azarsina

Volume 4, Issue 2 , June 2014, Pages 77-88

  Offshore structures such as jacket platforms have to inevitably be designed against  sever  environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded  in recent earthquakes, including the 1995 Kobe, ...  Read More

Unsteady aerodynamic analysis of different multi mw horizontal axis offshore wind turbine blade profiles on sst-k-ω model

M. Abbaspour; A.R. Radmanesh; M.R. Soltani

Volume 4, Issue 2 , June 2014, Pages 89-100

  To indicate the best airfoil profile for different sections of a blade, five airfoils; included S8xx, FFA and AH series was studied. Among the most popular wind power blades for this application were selected, in order to find the optimum performance. Nowadays, modern wind turbines are using blades with ...  Read More

Analysis of liquids and chemicals costs in a sample port

N. . Allahyaribeik; S. Allahyaribeik

Volume 4, Issue 2 , June 2014, Pages 101-106

  In recent years, the application of Activity-Based Costing in Port industry has been deeply researched in theory and practice, but researchers only concentrate on the bulk and general cargo’s ABC in loading and unloading operations and there is little about the liquids and chemicals’. Based ...  Read More

Effect of pH and salinity on growth and bloom of Dunaliella sp. algae

M. Alipour; M. Fallahi; T. Valinassab

Volume 4, Issue 2 , June 2014, Pages 107-111

  In this study, effects of pH and salinity on growth and bloom of Dunaliella sp. algae were investigated. The algae were reared in different pH (6.0, 6.8, 7.0, 7.3, 7.6, 8.0, 8.6, 9.0, 9.7 and 11.0) and salinities (20.0, 31.6, 50.1, 79.4, 117.1, 125.9 and 200.0 ppt) at Inland Aquaculture Research Institute ...  Read More
