I have seen this in the Wartsila and have heard of it happening in a MaK 16M453
The exhaust of each bank consists of 4 manifolds exhausting into the turbine nozzles. 2 cylinders feed each exhaust and this all balanced to provide constant pressure at the turbine.
We all immediately think that barking is caused on the compressor side, but in this case it was not so. After literally looking at every head, the intakes, cooler, we were at a loss to what the cause was. We finally started looking at the exhaust manifolds. What we found was that the manifolds have expansion bellows. Inside these stainless steel bellows are sleeves, welded in place. These sleeves keep the laminer flow of the exhaust gases. One of the sleeves had the welds fail and it went down the pipe and was flattened. It cut off the exhaust gas flow to the turbine on one nozzle which changed the speed of rotation rapidly. The compressor started surging. This sleeve would fall down in the manifold as the pressure dropped and as it built again would rise and jam the exhaust again and the cycle would start over.
All the engineers who worked on these Wartsila engines really liked them I think it was because we burn MDO and that takes a huge amount of work out of the job!
Another Turbo issue. Same engines.
The TC compressor inlet is directly ducted to the exterior, 3 decks above the engine. Engines work great, until the ship hits the Arctic and temperatures dropped to between -30 and -40*C. The ship is breaking ice and one engine in particular starts having the turbocharger surging. It is intermittant and no cause can be found.
What do you think it is?
