Abstract:Excessive vibration can cause fatigue failure in structure which may lead to serious structural integrity, operational and safety concerns in oil and gas facilities. Piping vibration at an offshore facility has resulted in several welding failures at its small-bore connection. Vibration measurement on the piping system classified it as severe risk according to recognized international standard and guideline. There are several methods to resolve the piping vibration issue by transferring the load to the structure. Consideration was made on factors such as the effect to the existing structure due to rectification work, construction complexity and cost. Viscous dampers were proposed to be installed asit transmits less vibration to the structure, thus minimising structural modification. This paper presents a case study on the impact of piping vibration to steel structure and its effect after viscous dampers installation.
