Longmen port area of Taizhou Port is an important part of Taizhou Port “One-Port Six District”. In the scale and level restriction of the approach channel，most of in-and-out port ships need to wait for the tide. Therefore，when setting up anchorages in the Longmen Port Area，both of the number of anchoring points for waiting berth and the number of waiting for the tide need to take into consideration. There is no recommended method to calculate the number of tide anchorage and anchoring points in the industry. This paper studies the anchoring points in Longmen Port Area according to the relevant research and standard. Using the theoretical analysis method of queuing theory，the number of tide anchorage and the number of anchoring points in Longmen Port Area are comprehensively measured，and the setting scheme of the number of tide anchorages （waiting for tide or waiting for tide+waiting berth）is obtained. That is to say，under the condition of consistent assurance rate，the number of anchoring points can take the larger of the number of waiting berth and waiting for the tide.
