船舶附加水动力组合节能技术研究进展

Research and development of marine hydrodynamic compounded energy-saving

随着国际上石油价格飞涨,能源短缺,特别是MEPC第58次会议发布EEDI计算公式以及MEPC第62次会议正式通过《MARPOL73/78公约》附则Ⅵ修正案,世界各国都认识到了船舶节能减排的重要性。船舶节能技术得到广泛的关注。相比于节能新船型和新型高效推进器,附加水动力节能装置无疑是一种成本低廉、见效显著、安装方便的节能选择。通过合理搭配2个或多个不同附加水动力节能装置,充分利用各自的水动力特性可以得到更好的节能收益。本文主要介绍基于导管类的附加水动力组合节能装置、基于导流鳍的附加水动力组合节能装置、基于扭曲反应舵的水动力组合节能装置,并分析各节能装置的节能原理与节能效果等。

The countries all-around the world have recognized the importance of marine energy conservation, and the techniques of ship propulsion and its energy-saving has been widely focused during the up-trend prices of ship fuel oil, and the shortage of energy, especially the formula of EEDI was given in the 58th conference of MEPC, and the annex VI amendment of MARPOL 73/78 PROTOCOL was formally adopted in the 62nd conference of MEPC. Compared with new energy-saving type of ship and highly efficient propeller, hydrodynamic energy-saving appendages is undoubtedly a kind of low cost, effective significant, convenient installation energy-saving choice. We can get better energy-saving benefits by combining two or more different kinds of hydrodynamic energy-saving appendages. The research and development of the hydrodynamic compounded energy-saving device were introduced in this paper, such as the hydrodynamic compounded energy-saving device base on ducts, the hydrodynamic compounded energy-saving device base on fins, the hydrodynamic compounded energy- saving device base on twisted rudder, and then the principle and effect of the hydrodynamic compounded energy-saving device was analyzed.
