Abstract

IN THIS RESEARCH, CURRENT AND WAVE, WHICH HIT THE RISER, ARE NUMERICALLY MODELED AND THE CYCLIC LOADS ON THE RISER ARE OBTAINED ON VARIOUS PARTS. TO ANALYZE THE FORCED VIBRATION, THE MODAL ANALYSIS APPROACH WAS APPLIED. FOR THIS PURPOSE, THE DOMINANT VIBRATION EQUATION WHICH INCLUDES ALL THE HYDRODYNAMIC AND STATIC FORCES, WAS SOLVED NUMERICALLY AND THE NATURAL FREQUENCIES AND RISER VIBRATIONAL MODES WERE COMPUTED. THEN, THE VIBRATIONAL MOVEMENTS OF RISER IN EFFECT OF EXTERNAL FORCES WERE OBTAINED. TO APPROXIMATE THE SOLUTION TO THE REAL SITUATION, THE RELATIVE SPEED BETWEEN FLUID AND VIBRATIONAL RISER WERE APPLIED IN SOLVING THE VIBRATION EQUATION.
