On October 9, 2023, the Ocean Navigator
passenger vessel owned by Victory Cruise Lines
00:06.039 –> 00:09.600
began a 10 night cruise from Montreal, Canada
to Boston,
00:09.680 –> 00:15.250
Massachusetts with 128 passengers and 82 crew
members aboard.
00:15.939 –> 00:20.139
9 days later at about 7 a.m., the vessel was
docked in Portland,
00:20.219 –> 00:25.889
Maine when a fire broke out in the engine room.
The NTSB released a report this week that
00:25.889 –> 00:29.690
traced the fire to debris in the engine’s lube
oil system,
00:29.899 –> 00:35.020
which led to a catastrophic mechanical failure
in the #2 auxiliary diesel generator engine.
00:35.380 –> 00:39.919
The fire injured a crew member, but it itself
extinguished after the crew ventilated the
00:39.919 –> 00:45.259
engine room.
Still, the incident caused some $2.4 million in
00:45.259 –> 00:48.500
damage.
Just before the fire, two crewmen were
00:48.500 –> 00:53.060
performing maintenance in the engine room when
they discovered a small lube oil leak on the
00:53.060 –> 00:54.619
number two auxiliary engine.
00:55.080 –> 01:01.139
The 3 engineer told the NTSB, quote, The bolt
was loose as we could see it turning.
01:01.349 –> 01:06.190
The pair ran to get tools to tighten the bolt,
but when they returned and sat beside the
01:06.190 –> 01:12.260
engine, it exploded and fire immediately spread
across and above the generator.
01:12.470 –> 01:18.269
The fire set the motorman’s coveralls on fire,
and he suffered burns to about 40% of his body.
01:18.580 –> 01:21.260
Third party technicians were brought in
following the fire.
01:21.540 –> 01:24.580
Tear down the engine and they found significant
damage.
01:24.769 –> 01:29.440
NTSB investigators determined that the debris
in the engine lube’s oil system,
01:29.650 –> 01:35.489
which caused the engine failure was possibly
caused by the crew exceeding manufacturer
01:35.489 –> 01:39.040
recommended intervals for changing the lube oil
and oil filter.
01:39.209 –> 01:44.930
The crew last changed the entire quantity of
lube oil for the engine in September 2022,
01:45.050 –> 01:47.860
about 13 months before the engine failure.
01:48.379 –> 01:52.989
However, the engine operated for more than 5000
hours with this lube oil,
01:53.260 –> 01:56.809
5 times longer than the manufacturer’s
recommendation.
01:57.139 –> 02:01.980
Since the filter was changed in May 23, the
engine had run more than 3000 hours,
02:02.449 –> 02:04.959
3 times longer than recommended.
In the reports,
02:05.110 –> 02:10.940
the NTSB said, quote, manufacturers provide
maintenance recommendations and intervals to
02:10.940 –> 02:12.899
ensure equipment operates safely.
02:13.434 –> 02:18.994
Optimally and reliably throughout its service
life, NTSB did note that the crew’s quick
02:18.994 –> 02:24.395
action prevented the fire from spreading.
The 300 ft long passenger vessel was originally
02:24.395 –> 02:29.304
built in 2004 at Atlantic Marine Shipyard in
Jacksonville, Florida.
02:29.634 –> 02:32.315

This is manufacturing now.
