结伴航行保间距，两船相吸需警惕

船吸导致的碰撞事故

一 What the type of casualty ？

Very serious marine casualty : Foundering due to hull-to hull interaction

非常严重的水上交通事故：由于船体碰撞导致船舶沉没

二 What happened ?

An 11 m work boat was acting as the lines boat assisting the berthing of a 68 m, 1,000 GT motor tanker. With the ship underway, the work boat was manoeuvred close in to the ship's bow in order to retrieve a mooring line. In this position, the hull-to-hull interaction forces caused the work boat to turn across in front of the ship's bow. The resulting collision capsized the work boat. Both occupants made it safely clear and suffered only minor injuries.

一艘11米长的工作船作为带缆船正在协助一艘68米长、1000总吨的油船靠泊。在油船航行过程中，工作船驶近油船船首的位置回收系泊缆。在此位置，两艘船的船体发生碰撞，导致工作船在油船船首部发生转向，由此产生的碰撞造成工作船倾覆，幸运的是两名船员均安全撤离，只是轻微受伤。

三 Why did it happen ?

The work boat was manoeuvred in very close to the moving ship to aid the retrieval of the mooring line. In this position, close to the ship's hull, the coxswain of the work boat underestimated the interaction forces acting between the two vessels.

工作船紧挨着航行中的油轮行驶，以便收回系泊缆。在靠近船体的位置，工作船的舵工低估了两艘船之间的相互作用力。 

四 What can we learn ？

● Interaction forces between two moving vessels can be sufficiently large to seriously affect the manoeuvrability of either or both vessels. This is particularly important for small vessels when manoeuvring close to a larger vessel, as the forces can quickly cause a dangerous situation to arise.

● Masters and coxswains of all vessels, including port service vessels and work boats, should be fully aware of and trained in the dangers associated with hull-to-hull interaction.

1. 两艘航行中船舶之间的相互作用力可以大到足以严重影响其中一艘或两艘船舶的操纵性能。这点对于小船在靠近大船航行时尤为重要，因为这种作用力可以迅速导致紧迫局面的出现。

2. 包括港口服务船和工作船在内的所有船舶的船长和舵工，都应充分认识到船体间的相互作用所带来的危险，并接受相关的培训。

五 Who may benefit ？

All vessel crew members including port service providers.

包括提供港口服务在内所有船舶的船员。
