ABB TPS50 Turbocharger Damage

ABB TPS50 Turbocharger Damage

Recently we were sent a turbocharger. The operators had reported a knocking noise, and they wanted us to have a look. As it turned out, the turbo had recently been overhauled by another company, and after the overhaul, it had only run for 20 hours before this knocking noise was heard. The video above shows a quick snapshot of what we found. As you’ll see, a large number of the components have been discoloured and damaged due to excessive heat...

Swing sets; not just for generator engine turbochargers

Swing sets; not just for generator engine turbochargers

At the end of last year, we started working with Maersk, the world’s largest shipping company, and we introduced them to the idea of “swing sets” for their generator engine turbochargers. Thought I’d share something that has been widely used on safety critical engines in the oil and gas market but is now being embraced in other industries.   With the swing sets in place, they saved over 68% on the overhaul cost of their turbocharger and...
