长江口是船舶进出长江和上海港及南北航行船舶的必经之道。目前定线制水域日均船舶流量超过1000艘次，航经该水域的船舶主要为进出南北槽船舶及南北线过境船，船舶种类多、船舶尺度大、抛锚船舶多、过境船舶多。由于长江口船舶定线制水域的船舶有东西向和南北向航行，加之进出锚地的抛起锚船舶，多船之间相互交叉的态势非常复杂。
通告目的
为防范化解长江口及其附近水域船舶交通事故风险，缓解长江口 A、B 警戒区通航压力，提升整体通航效能，保障海上交通安全、有序、畅通，根据《中华人民共和国海上交通安全法》和《长江口船舶定线制（2008）》，对长江口及其附近水域的船舶交通流引导分流，上海海事局发布关于进一步加强长江口及其附近水域船舶交通管理的通告。

长江口水域船舶交通组织示意图
1、南北向过境船舶推荐航路>>
南北向沿海过境船舶航行于长江口及其附近水域时，优先选用津广外航路（123°00′E经线的南北习惯航路或者分流水域（122°45′E经线至 122°50′E经线之间水域）航行。
2、吴淞VTS船舶交通组织>>
如安全可行，航经长江口 A、B 警戒区的船舶，优先考虑下列航行建议，并听从 VTS 现场指挥：
01
自长江口驶入长江口深水航道的船舶，可以使用长江口C1通航分道于长江口A警戒区转向，或者使用分流水域、津广外航路转向驶入长江口 A通航分道；
02
自长江口深水航道驶往长江口，拟转向北上或者南下的船舶，沿长江口A通航分道向东行驶，使用分流水域或者津广外航路转向；
03
自长江口驶入南槽航道的船舶，可以使用长江口C3通航分道于长江口B警戒区转向，或者使用分流水域、津广外航路转向驶入长江口B通航分道；
04
自南槽航道驶往长江口，拟转向北上或者南下的船舶，沿长江口B通航分道向东行驶，使用分流水域或者津广外航路转向；拟转向南下的船舶也可以在长江口B警戒区转向。
3、航行注意事项>>
船舶应当根据通航环境和水文气象条件，考虑渔船渔网分布、自身操纵性能、抗风能力等因素设计航线，服从VTS为确保航行安全和通航效率所采取的现场交通组织措施，并遵守《1972年国际海上避碰规则》和《长江口船舶定线制（2008）》等有关规定。
4、船舶锚泊要求>>
船舶要根据航行计划、船舶吨位等合理选择锚地，进出锚地时，与周围船舶统一避让意图。船舶不得在分流水域内锚泊，紧急情况下锚泊应当立即向海事管理机构报告。
5、南槽航行注意事项>>
航经九段沙警戒区至南槽航道大风浪进口引航作业区之间的船舶，要特别注意航道边界附近水域的水深变化情况。

Circular of Shanghai Maritime Safety Administration on Further Strengthening Vessel Traffic Management in Changjiangkou and its adjacent waters
(In case there is any discrepancy between the Chinese edtion and the English edition, the Chinese edtion shall prevail)
In order to prevent and reduce the risk of vessel collision accidents in Changjiangkou and its adjacent waters, relieve navigation pressure in the Precautionary Areas A and B, improve the overall navigational efficiency, and ensure the safe, well organized and smooth maritime traffic, in accordance with the Maritime Traffic Safety Law of the People’s Republic of China and Changjiangkou Ship Routing System (2008), the separation of ship traffic flow in Changjiangkou and its adjacent waters is guided as follows:
1. The pass-by vessels from south or north navigate in Changjiangkou and its adjacent waters shall prefer to choose the Tianjin-Guangzhou Outer Routing (the north-south customary route along the longitude 123 °00 ′E) or the diversion waters. ( between longitude 122 °45 ′E and 122 °50 ′E)
2. If it is safe and feasible, vessels passing through the Precautionary Areas A and B of the Changjiangkou Traffic Separation Schemes (CJK TSS) shall give priority to the following navigation suggestions and navigate under VTS’s organization:
2.1 Inbound vessels proceeding to Changjiangkou Deepwater Channel ( North channel ) from Changjiangkou waters shall take turns in the Precautionary Area A through the traffic lane C1 of CJK TSS, or turn into the traffic lane A through the diversion waters or the Tianjin-Guangzhou Outer Routing.
2.2 Outbound vessels sailing from Deepwater Channel to Changjiangkou waters, and intending to turn northward or southward, shall proceed eastward by TSS lane A, and take turns in the diversion waters or the Tianjin-Guangzhou Outer Routing.
2.3 Inbound vessels proceeding to South Channel from Changjiangkou waters, shall take turns in the Precautionary Area B through the TSS traffic lane C3, or turn to TSS traffic lane B through the diversion waters or Tianjin-Guangzhou Outer Routing.
2.4 Outbound vessels sailing from South Channel to Changjiangkou waters, and intending to turn northward or southward, shall proceed eastward by the TSS traffic lane B, and take turns in the diversion waters or the Tianjin-Guangzhou Outer Routing. Vessels intending to turn to south could also take turns in the Precautionary Area B.
3. Vessels shall make the voyage plan according to the navigation environment and hydro-meteorological conditions, taking into account their own manoeuvrability, performance of wind resistance, distribution of fishing vessels and fishing nets and other factors, comply with the on-site traffic organization measures taken by VTS to guarantee navigation safety and efficiency, and comply with the International Convention on the rules of collision avoidance by sea (1972) and Changjiangkou Ship Routing System (2008) and other relevant provisions.
4. Vessels shall reasonably select the anchorage according to the sailing plan, ship tonnage, etc. Vessels shall verify their intentions with other vessels to avoid collision when entering or leaving the anchorage. Vessels shall not anchor in the Diversion waters, and shall report to VTS immediately when dropping anchor in an emergency.
5. Vessels sailing through the Jiuduansha Precautionary Area to the South Channel Pilot Waters in strong wind and waves condition , shall pay attention to the water depth changes near the channel boundary.
