Scour is a process that is occurring by reason of disturbed flow conditions in the case of existence of submarine pipeline on the seabed. When pipelines are placed on the erodible seabed changing flow (wave/current) conditions cause scour around pipes and this leads the system to stability problems. Geotextiles are permeable textiles which are produced as either woven or non-woven and used in lots of industrial areas. They also have a wide usage in coastal engineering such as for coastal erosion control and in reefs, breakwaters, revetments. In this study, it is aimed to determine the effect of usage of geotextile material for scour protection of submarine pipelines experimentally. In this context, scour is examined in the wave flume by using two pipes and placing geotextile material under regular wave conditions.

An investigation of two-phase slug flow in inclined pipelines Bağcı, Ali Suat (Informa UK Limited, 2004-06-01) Two-phase slug flow in inclined pipelines can cause significant practical operating problems. When slugs flow in an inclined pipeline that contains sections of different inclinations, they undergo a change of length and slug flow characteristics as the slug moves from section to section. In addition, slugs can be generated at low elbows, dissipate at top elbows and shrink or grow in length as they travel along the pipe. A mathematical model and a computer program were developed to simulate these phenomena. ...
An Investigation of the Ground Motion Scaling Procedures for the Nonlinear Seismic Analyses of Concrete Gravity Dams Soysal, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (2019-07-03) Seismic assessment of gravity dams is generally carried out using time history analyses. Scaling of the motions is commonly used; however, in contrast to buildings, the performance of scaling procedures at predicting the mean and reducing the dispersion in engineering demand parameters (EDPs) is not known. The main goal of this study is to assess the performance of different scaling procedures in predicting seismic demands on dams. The performance regarding the prediction of the damage and the required numb...
A study on dam instrumentation retrofitting Yanmaz, Ali Melih; ARI, Onur (2011-02-01) Continuous monitoring and inspection of large dams would provide means for proper rehabilitative actions to be taken on time which intend to maintain the desired safety throughout the physical life of dams. Comprehensive inspections can be carried out using a number of instruments. An ideal dam instrumentation system should provide time-dependent information about critical parameters so that possible future behaviour of the structure can be predicted. Numerous of the existing dams do not have adequate instr...
Evaluation of limestone incorporated cement compositions for cementing gas hydrate zones in deepwater environments Hıdıroğlu, İnanç Alptuğ; Parlaktuna, Mahmut; Yaman, İsmail Özgür; Department of Petroleum and Natural Gas Engineering (2017) One of the potential problems which must be overcome during oil or gas exploration in deepwater environments is to complete the drilling operations without decomposing the gas hydrates. Gas hydrates remain stable as long as the thermodynamic conditions are not changed. But, especially by increasing temperature during drilling operations, there is always a possibility of change in thermodynamic conditions, which will cause decomposition. Another factor which may disturb the thermodynamic conditions is the ev...
A preliminary study on the use of reservoir simulation and coal mine ventilation methane measurements in determining coal reservoir properties Erdoğan, Sinem Setenay; Okandan, Ender; Kracan, Cevat Özgen; Department of Petroleum and Natural Gas Engineering (2011) This thesis investigates methane emissions and methane production potentials from abandoned longwall panels produced or emitted due to mining activities either from coal seam or any underlying or overlying formations. These emissions can increase greenhouse gas concentrations and also pose a danger to the underground working environment and to miners. In addition to the safety issues, recovery and utilization of this gas is an additional source of energy. In this study, methane concentrations measured from ...
