Purging of the oil unloading pipeline at the dock
Thread Content
Has anyone encountered problems with the purging of oil unloading pipelines at docks? What solutions have been adopted? Previously, after draining the oil, it was sufficient to close the valve. . Now, due to environmental concerns, there is a fear that oil stored in pipelines might leak into rivers, so oil storage in pipelines is not allowed. . What methods is everyone using to get rid of them? We plan to purge with nitrogen and ball delivery/takeaway cylinders, but the problem is how to get the balls through the hoses. .
The pipeline cleaning in our ports here is usually done by ball blowing
How should the metal hose section be handled? Is it also cleaned with a ball?
Where is the flexible metal hose installed, and why are there problems? Generally, metal hoses are installed at the base of the storage tank; once the ball is passed to the manual valve, the valve is closed, and then the ball is removed or blown back in the opposite direction before being taken out again.
How should the metal hose section be handled? Is it also cleaned with a ball? The question is strange

In addition to the base of the storage tank, there are also hoses on the quay barges, mainly used to adjust the water level. . The main issue is dealing with the area from the river surface to the slope. . Includes metal hose.
That means there are hoses only at both ends, with none in the middle; a ball is passed over the hoses, and the oil from the front part is collected in barrels.
