冠诚挖泥船：
绞吸式挖泥船起源于美国。1884年第一艘绞吸式挖泥船在美国加利福尼亚州西部港市奥克兰使用。这艘绞吸式挖泥船装有液压绞刀头并被用于疏浚泥沙和岩石。其输泥管直径为500 mm，泥泵叶片直径为1.8 m。其设计的主要缺点是绞刀头易被堵塞。在19世纪末20世纪初，绞吸式挖泥船得到了发展。       如，1896年Beta 号绞吸式挖泥船是为美国芝加哥疏浚公司建造。这艘挖泥船吃水1.95 m，横梁长12 m，在当时是最大的绞吸式挖泥船。Beta 号具有两个独立的泥泵并配有直径为850 mm的吸泥管，每个吸泥管分为三段直径为500 mm的管子。在每个管口处垂直安装了一个直径为1500 mm的绞刀头。绞刀头转数为12 r/min， 绞吸式挖泥船的特性是：她属于静态挖泥船，安装绞刀头/绞刀作为挖掘工具，使泥土在切削后被吸入。在吸泥过程中，绞吸式挖泥船是以定位桩为中心通过固定在侧边绞盘上的锚缆按圆弧形旋转，绞吸式挖泥船非常易于与吸扬式挖泥船区分，因后者是没有定位桩系统的（但某些绞吸式挖泥船工作时是由缆绳定位的，而不是定位桩定位）

Crown-dredger:
Cutter suction dredger originated in the United States. In 1884 the first ship to use the cutter suction dredger in the western port city of Oakland, California. Aboard the cutter suction dredger and is equipped with a hydraulic cutter head for dredging sand and rocks. Its output mud tube diameter of 500 mm, mud pump blade diameter of 1.8 m. The main disadvantage of cutter head design is easily clogged. In the late 19th and early 20th century, the cutter suction dredger has been developed. For example, in 1896 Beta No. cutter suction dredger is built for Chicago dredging companies. Dredger ship draft 1.95 m, beam length of 12 m, at the time was the largest cutter suction dredger. Beta No. mud pump has two separate and with a diameter of 850 mm in the suction tube, suction tube is divided into three sections each having a diameter of 500 mm pipe. In each nozzle mounted vertically at a diameter of 1500 mm of cutter head. Cutter head rpm for 12 r / min, cutter suction dredger features are: She is a static dredger mounted cutter head / reamer as mining tools, so the soil in cutting after inhalation. In the suction process, the cutter suction dredger is positioned as the center of the pile on the side of the fixed anchor winch cable arc-shaped rotary press, cutter suction dredger is very easy to distinguish with suction dredger Young because the latter is no spud system (but some cutter suction dredger is done by cable positioning, rather than spud location)
