VCI was tasked with performing vibration analysis, using a mix of online and offline hand-held data collection techniques, on over 100 assets on-board a cargo vessel as part of an ongoing monitoring programme.
After overhauling the main engine turbochargers during dry docking, the vessel exited the yard and, upon reaching full speed, one of the turbochargers went into an alarm condition on the VCI asset protection system.
VCI engineers swiftly reacted to the alarm to determine the cause of the increase and immediately contacted the vessel’s crew and asked them to inspect the turbocharger for signs of oil starvation.
The vessel’s crew discovered that on the run-up to full speed, a structural securing bolt within the turbo had fractured and blocked the supplying oil gallery. Due to the early detection, the damage was limited.
Following VCI’s review, the turbocharger manufacturer issued a worldwide bulletin informing all service teams and end users of issues surrounding sub-standard bolts being used during turbocharger overhauls. The estimated cost avoidance of preventing a catastrophic turbo failure was reported as $224,320 by the cargo vessel operator.
