For the past three years we have been experiencing repeated failures of the main bearings on our two 5 RTA 58T-B engines, particularly in way of Main Brg #5(the middle bearing).
Does anyone else have such experiences and if so what have they found to be the problem/solution.
On our vessels we...
Does anyone have experience of cracking of the piston crwon on RTA 52-U engines, in way of the lifting bolt holes.
The material has been tested and is o.k. The radius of the holes has been checked and is o.k. Injector spray pattern is now under checking but the problem persists.
Any input and...
Our vessels are suffering from extensive pitting corrosion inside the inert gas scrubber tower.
The scrubber towers on these vessels are manufactured from Stainless grade AISI 316L.
We also have an older vessel with an inert gas system from the same manufacturer where there is no corrosion...
Would appreciate views and pointers to reference material/sites with respect to the use of inert gas - either from boiler flue gas or independent inert gas generators - to prevent/retard corrosion in the upper vapour space of the uncoated mild steel cargo tanks of ships carrying heated fuel oil...
I'd like some feedback and experience from all the marine/materials/corrosion engineers on the positive effects of the use of inert gas - either from boiler flue gas systems or from independent inert gas generators using MGO - to prevent or significantly slow down the rate of corrosion of the...
