The invention provides an offshore dock for measuring underwater radiated noise of a ship. The dock comprises a dock shell and a dock gate, the dock shell is of a double-layer box type structure, thecross section of the dock shell is concave, the dock shell base enters the seabed, the top of the dock shell base is higher than the sea surface, the inner layer and the outer layer of the dock shellare both sound insulation plates and supported by a support, an air layer is arranged between the inner layer and the outer layer of the dock shell, and the dock door is a semi-cylindrical flow guideopening arranged at the middle portion of the head and tail ends of the dock and extending inwards an opening. According to the offshore dock for measuring underwater radiated noise of the ship designed from the acoustic perspective, the sound insulation performance and the water flow dredging capacity are fully considered in structure, necessary rigidity and stability are guaranteed, enough shipnormal operation space is provided, and a large test platform for acoustic diagnosis and evaluation is provided for ship design, construction and navigation.

    本发明提供的是一种用于船舶水下辐射噪声测量的海上船坞。包括坞壳和坞门,所述的坞壳为双层箱式结构、横截面为凹字形,坞壳基座入海底、顶部高于海面,坞壳的内外层均为隔声板、内外层之间支架支撑,坞壳的内外层之间为空气层,所述的坞门为在船坞首尾的中部向内侧开口延伸的半圆柱形导流口。本发明从声学角度入手设计的船舶水下辐射噪声测量船坞,在结构上充分考虑隔声性能和水流疏导能力,保证具备必要的刚度和稳定性,并提供足够的船舶正常运作空间,为船舶设计、建造及通航提供了声学诊断和评价的大型测试平台。
