Structural Aspects

Ordu-Giresun Airport, which has been constructed recently, being an example of the aviation sector of Turkish transportation network, is a project having marine structural aspects due to the construction at the sea by filling and in this workout physical model experiments of the project are evaluated. 3000-meters-long runway and the other superstructures of the airport, the first example of construction of such a structure by filling in the sea in Turkey, is to be protected by a breakwater of 7435 meters long. ‘First Cross Section’ has been prepared by using experimental formulas and artificial neural network and ‘Second Cross Section’, being the alternative of the first one has been planned. Yet, both cross sections have similar characteristics, they have berm heights in such a manner that ‘First Cross Section’ enables the structure to be constructed from the sea, whereas ‘Second Cross Section’ makes it possible from the land. Both cross sections are aimed to be evaluated in terms of stability, wave overtopping and economy through the hydraulic model studies performed at the Hydraulics Laboratory of Turkish Ministry of Transportation, Maritime Affairs and Communication. Starting from design stage (computation of design wave characteristics, physical model experiment under different wave conditions on different structure alternatives) to construction stage the engineering studies is presented with comparisons and discussions.

The aim of this study is to develop a numerical tool that could be used to assess the physical stress levels associated with the vessel motions on board of fishing vessels of the Newfoundland fleet. A number of full-scale sea trials of typical fishing vessels of the fleet are underway to validate the numerical tool. Model experiments are expected to follow in the near future. If desirable correlations between the trials, model tests and the numerical results are obtained, simulations will be performed to obtain typical ‘motion stress’ profiles of various fishing boats over a typical fishing season. This paper presents the preliminary results obtained so far. Sea trials for a 35’ fishing vessel was conducted. Sample results presented in the paper. Motion Induced Interruption (MII), which will be used to assess the physical stress levels has been implemented into the numerical tool and few case studies performed for the 35’ fishing vessel. Results obtained so far seem promising.

Lift And Drag

A case study was conducted to investigate and quantify stabiliser fin-hull interaction using a combination of Computational Fluid Dynamics and physical model experiments. The fin-hull interaction was studied by comparing the lift and drag of a stabiliser fin in a free stream condition and when attached to a hull. The findings of this case study showed that using free stream fin characteristics to predict performance of a stabiliser fin fitted to the hull resulted in an over-prediction of drag by up to 46% and under-prediction of lift by up to 75% for the speeds and angle of attack analysed. These discrepancies are for this case study only and in practice will vary for different hull forms, fin types, fin location and angles of attack. However, the research highlights the limitations of using free stream fin characteristics to predict the performance of a fin fitted to a hull.
