| Abstract | Pipeline play vital role in the delivery of the oil and gas. The accidentally damage of pipeline will create the major impact in oil and gas operation and cons equence a significant amount of loss. Therefore, subsea pipeline has to be protected from accident. The behavior of slender dropped object was suited thru small scale experiments. Four type of slender object, Drilling Collars (DC), 7- inch Casing (7C), 9-inch Casing (9C) and 13- inch Casing (13C) and four different drop heights, 25 mters,20 meters, 15 meters, 10 meters were selected The data recorded by high speed camera and calculated for motion path, incident angle and kinetic energy. The resu lt shows that in different drop height give the different incident angle and motion path. Th e velocities remain constant after reach the terminal velocity. The kinetic energy distributions were compared with DNV RP F-107 and considered the risk assessment for assess ing pipeline protection against external loads by this experiment and DNV RP F-107. All of the results of this study can be use for planning the lay out, loading area and the protection design under operati onal requirement with satisf actory safety level. |
