三、抛锚定位漂浮在动荡水面的钻探船，受水流、潮涌、风力的影响很大，为使钻船上的天车、迴转器中心与设计在水底的钻孔中心能保持在一条直线上，必须根据不同情况、按照不同要求设置简单、可靠的锚泊系统。浙江水文队的拖航式钻探船在近海施工时，锚泊系统由主锚、边锚、锚绳、锚链、锚浮标和绞锚机组成。主、边锚均选用山字型锚，钻船前后各布两个主锚，锚绳夹角90°，单锚重250—500公斤。锚绳为
Third, anchor positioning Floating in the turbulent surface of the drilling vessel, subject to water, tidal, wind a great influence, in order to make the crane on the boat, the center of the rotor and the design in the bottom of the drilling center can be maintained in a straight line, Must be based on different situations, in accordance with the requirements set simple, reliable anchoring system. When the Zhejiang Hydrographic Department towed drilling vessel is in offshore construction, the anchor system consists of main anchor, side anchor, anchor rope, anchor chain, anchor buoy and anchor winch. Main and side anchors are selected mountain-shaped anchor, before and after the drill two cloth anchor, anchor angle of 90 °, weight 250-500 kg single anchor. Anchor rope for
