The invention discloses a marine maintenance method for an outboard discharge short pipe of a ship, which is characterized in that when the outboard discharge short pipe leaks or is damaged, the outboard discharge short pipe is exposed out of the water surface by adjusting ballast water, and a damaged pipe section on the outboard discharge short pipe can be cut, replaced and maintained in a cabin. And then the tightness detection device is installed in the maintained exhaust outboard short pipe to carry out a tightness test, so that the problem that the risk coefficient is high when a frogman carries out underwater outboard maintenance operation is effectively solved, the tightness test can be completed in a cabin by only one sailor, a tug and the like do not need to be used in an auxiliary manner, the workload is small, and the test cost is low.

    本发明公开了一种船舶排舷外短管海上维修方法,该方法在排舷外短管出现渗漏或破损时,通过调整压载水的方式使排舷外短管露出水面,在机舱内即可将排舷外短管上的破损管段切割替换掉,对其进行维修,然后将密性检测装置安装在维修好的排舷外短管内对其进行密性试验,有效地解决了蛙人在水下船外维修作业所面临的风险系数高的问题,且密性试验仅需一个船员在机舱内就能完成,不需要辅助使用拖轮等,工作量小,试验成本低。
