        Abstract:Dropped objects may cause fatalities and serious injuries in the offshore oil and gas industry. Objects may accidentally fall down from offshore platforms during lifting or any other offshore operation. In this presentation, an open-access database, named Potential and Actual Dropped Object Incidents and Statistics (DORIS) will be firstly introduced. DORIS provides a visual method of recording and presenting real dropped object incidents. Secondly, the current industrial guidance or classification rules about dropped objects in offshore operations will be addressed, including “Guidance Notes on Accidental Load Analysis and Design for Offshore Structures” by American Bureau of Shipping (ABS) and “Risk Assessment of Pipeline Protection” by Det Norske Veritas (DNV-RP-F107). Thirdly, a new three-dimensional (3D) theory of dynamic motion of a dropped cylindrical object will be introduced. It has been integrated into Dropped Objects Simulator (DROBS). DROBS is utilized to simulate the trajectories of dropped cylinders, and it is further used to derive the landing point distribution of dropped cylinder in currents based on Monte Carlo simulations. The overall landing point distribution plots can provide a simple way to estimate the risk-free zone. Finally, some ongoing research projects at University of New Orleans (UNO) will be briefly introduced.
