Finally!

For years I was trying to find proper professional naval English analog to Russian бухтиноватость and lo and behold, my love of the channel Battleship New Jersey delivered--it is Oil Canning! 

Here it is--not bubbling, not whatever else, but Oil Canning. Here it is on modern ships:
 

Here is Peter the Great showing oil canning. 

This is a feature, not a bug. Albeit naval architects do have distinction between low and high oil canningness. Here is USS Zumwalt showing a rather elevated level of oil canning. 

So, now I know and I thought I should share this happy fact with you.
