What is the anchor Specific Operation and Command Method

Choice of anchorage : the choice of anchorage will directly affect the effectiveness of anchoring and the safety of the ship.The following aspects should be considered:

(1)Anchor meteorological conditions: listen to local meteorological reports in a timely manner and pay attention to weather changes;Choose anchor according to wind direction, wind speed and other weather conditions to avoid being attacked by wind and waves.Especially in the typhoon season, more attention should be paid.

(2) water depth and bottom quality: it is advisable to choose a place where the current is not too fast or there is no backflow, flower-water phenomenon and the seabed is relatively flat.According to the draft of the ship should choose the appropriate depth, generally not less than twice the draft (if you can choose).The sediment quality directly affects the holding power of anchor, the best holding power is clay, the second is silt.For example, the sea bottom slope is very steep or the bottom material is gravel, small stones, shells, rocks and other areas with poor grasping force, which is generally not suitable for anchoring. The water depth is more than 70 meters, which is generally not suitable for anchoring, because the anchor is not easy to be twisted.

(3) surrounding environment.The anchor shall have sufficient position for the convenience of the vessel in anchoring and lifting the anchor, and shall not interfere with the navigation of other vessels as far as possible. There shall be no reef or shoal around it.Shelter anchorage should be covered by suitable land or island.If the anchorage is open to the sea, the wind should be blowing from the shore to the sea.Since this wind cannot cause swell, in case of anchor, the ship will be blown to the sea, otherwise the ship will be blown to the shore.
