Application of microbial remediation in the treatment of offshore oil pollution

With the development of offshore oil industry, the pollution caused by frequent oil spill accidents has brought great pressure to marine ecology. How to repair the oil polluted sea area economically, efficiently and safely has become an urgent problem to be solved in marine ecological environment protection. In this paper, the main factors affecting the bioremediation of marine oil pollution are the polluted sea environment, the physical and chemical properties of oil and the types of microorganisms. The research progress of marine ecological restoration at home and abroad and the main research direction of marine oil pollution ecological restoration technology are summarized. The possible problems in the repair application are analyzed, and the further research direction is proposed.

Analysis and Suppression of Harmonics Generated on Offshore Oil Production Platform

With the continuous development of offshore oil industry, an increasing number of offshore oil production platforms will appear in different large sea areas. For the offshore oil production platform grid, which is an independent and small power distribution system far away from land, its power quality is extremely crucial. Various kinds of electrical and instrumental equipments have increasingly higher demand on the security and reliability of the power distribution system’s operation. However, when some nonlinear electrical devices and high capacity equipments start, they will generate a great amount of harmonic in the power distribution system on the platform and bring hidden trouble to various kinds of electricity load operations. Since this issue has aroused wide attention, the present paper takes the power distribution system of a central offshore oil production platform in an area of China’s sea as an example. First, it discusses the harm of harmonic in the power distribution system on the offshore oil production platform. Then, it proves the effect of harmonic suppression on the basis of a combination use of passive power filter (PPF) and active power filter (APF).
