超深水半潜式钻井平台总体噪声分析研究

Study on Global Noise of Ultra Deepwater Semi-submersible Drilling Unit

对第七代超深水半潜式钻井平台的主要噪声源进行了分析,通过建立统计能量分析模型对平台的总体噪声进行了预测。计算得到了平台各典型舱室的声压级水平,针对噪声超标房间给出了解决方案,并通过实际海试测试验证了方案的可行性,为后续半潜式平台噪声控制提供了参考。

The main noise sources of the seventh generation ultra deepwater semi-submersible drilling unit are analyzed. The global noise is predicted by establishing the statistical energy analysis model. The acoustic pressure levels of all typical cabins on the drilling unit are gained. The solutions are put forward for the cabins whose levels exceed the standards. The sea trial result proves the feasibility of the solutions. It provides a reference for the future noise control of semi-submersible drilling unit.
