تاثیر ابعاد هندسی بدنه سکوی پایه کششی در پاسخ سازه تحت اثر امواج
Tension leg platforms are compliant structures for oil extraction in deep water consisting of hull, deck foundation, tendons and risers. The hull is very important part of a TLP from functionality, weight and cost point of views that is made of vertical column and horizontal pontoon with circular and rectangular sections. The hull geometry plays very important rule in optimum action of the stru...
متن کاملبررسی آزمایشگاهی ارتفاع بهینه تیغه بر روی میزان عبور امواج از موج‌شکن‌های شناور پانتونی تیغه ای
In the present paper optimum height of skirt of Skirt Pontoon Floating Breakwater are reported by physical model. 54 tests on 3 types (skirt heights : 8,16 and 24 cm) of skirt pontoon floating breakwater is conducted in the wave flume of Soil Conservative and Watershed Research Center. Hydrodynamical and geometrical parameters were analysised. In this research optimum height of skirt to water d...
متن کاملبررسی آزمایشگاهی تاثیر آبخور، جرم و ارتفاع تیغه موج‌شکن شناور پانتونی تیغه‌دار بر میزان ضرایب انتقال و بازتاب در معرض امواج نامنظم
In this research study, effects of the draught and sheet height in pontoon floating sheet-breakwaters on the transmission and reflection coefficients against irregular sea waves was investigated. The project has been carried out using an experimental method within a wave flume of Soil Conservation and Watershed Research Institute. The incident waves were irregular and the wave spectrum was JONS...
متن کاملStudy on Connecting Method of Box Pontoons
Due to a lot of limited conditions, a large box type floating structure is inevitably constructed by connecting many pontoons. When a floating structure is made with concrete, concrete shear key with saw-teeth shape is often used to carry shear force. Match casting for the shear key and precise construction on a sea are very important for making separated two pontoons as one body but those are ...
متن کاملStress Patterns in Single Deck Floating Roofs Subjected to Ground Motion Accelerations
This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...
