Especially considering the engine itself and auxiliaries were intact enough to start back up and propel her slowly in to port. But being 37yrs old you’re right, it’s a numbers game at that point and the book value of the vessel was maybe less than the repair cost of fire damage to electrical wiring, the overhead gantry, areas of possible metal fatigue, a new turbo, and smoke and water damage.
An interesting read though. They don’t mention when the next turbo service interval was but that it had just over 12k hrs since the last. Most turbos I’ve seen have a maintenance due around 12k hrs.
