Normal sailing ships and crossing ships shall communicate in advance to clarify the intention of both parties to give way (the figure below shows the correct route of ferry).
6 Circular of Changshu Maritime Bureau on implementing traffic control over water areas related to water survey and construction of Haitai river crossing channel, and carried out a series of remediation actions.
The personnel on duty shall immediately remind the incoming ship to adjust the course away from the construction ship, and dispatch the standby tugboat on emergency duty to control the incoming ship.
The sub division reminds the ship that the following behaviors shall not be allowed when sailing through the construction water area! The construction water area for deviation from the route shall not occupy the navigation water area of the North upward recommended route and part of the main channel, which compresses the width of the main channel and increases the channel angle accordingly.
At about 0200 hours on the 25th, the ship was stranded with the anchor chain of 13-1# pontoon in the construction area, so it was unable to untie the anchor chain by itself.
4 and No.
The on-site maintenance Coast Guard “06830” responded quickly and immediately reminded the ship to drive carefully through high frequency, requiring it to sail according to the specified route and strengthen lookout.
The law enforcement personnel immediately gave a warning through VHF.
According to Article 20 of the regulations on restrictions on ships in Jiangsu section of the Yangtze River (2021), ships that need to cross the traffic separation and recommended route shall pay attention to the channel conditions and surrounding environment, and carry out at a large angle with the traffic separation and recommended route as far as possible without hindering the safe travel of other ships.
After the “Sea Patrol 0639” maintained on site is found, it shall immediately remind it to control the speed and drive carefully in the waters near the construction area on the high-frequency vhf10 channel to avoid wave damage and affecting the construction operation.
A total of 40 boreholes are expected to be completed by the end of September.
Finally, before the ship arrived at the construction warning water area, the ship position was controlled, and the danger of a passing ship breaking into the construction site was resolved.
After the sea patrol boat “06830” was found, it quickly contacted the ship through high frequency and informed the ship to the command center of Changshu Maritime Safety Bureau.
After repeated unsuccessful contact, the law enforcement personnel intercepted the ships breaking into the operation warning area by taking “Haixun 06838”, the warning boat continued to perform the warning task, and the tugboat made emergency preparations.
