Due to the interaction and corrosion of the seawater,submarine pipelines are easy to be broken to spill *** special environment of subsea restricts the technical development of pipeline ***,the study on the oil spilling model of submarine pipeline is very important for predicting the movement and diffusion of spilled oil,so that oil spilling traces and relating strategies can be *** paper aims to establish an oil spilling model of a submarine pipeline,study the movement characteristics of spilled oil in seawater by numerical simulation,and determine the traces,diffusion range,time to sea surface,***,the maximum horizontal migration distance(MHMD)with corresponding time are analyzed under different oil densities,spilling speeds and seawater *** show that the MHMD decreases first and then increases while the time to achieve the MHMD increases along with increasing oil *** MHMD increases while the time to achieve the MHMD decreases,along with increasing spilling *** the MHMD and corresponding time increase along with increasing seawater *** on numerical results,a correlation of spilling distance and spilling time is proposed to give fast and accurate *** the oil reaches sea surface,oil expansion and transport are ***-Lagrange method is used in the *** and non-dynamic factors are *** show that wind velocity and water velocity are dominant in dynamic *** they are large,spilled oil moves very fast with variable directions in complex flow *** factors such as evaporation,emulsion and solution mainly reduce the volume of oil *** almost do not affect the direction and displacement of spilled *** response should be made for large wind and water velocities when the placement of oil boom is *** the correlation and simulation,emergency responses can be guided effectively to reduce the impact of submarine o

Research Status of Technical Specifications for Bioremediation of Shorelines Polluted by spilling oil

引用

Meteorological and Environmental Research 2014年第1期5卷 62-64,67页

作者： Wu Liang Wang Xinxin Yang Yong Ocean University of China China Offshore Environmental Services Ltd. Tianjin University

Bioremediation of shorelines polluted by spilling oil has no secondary pollution and saves manpower and material resources, so it has a wide market. Standardizing the operation methods and materials used of the technology can improve its efficiency. Therefore, the research process of technical specifications for bioremediation of shorelines polluted by spilling oil at home and abroad was expounded in this study.
