A Russian AS-28 mini-sub with a 7 man crew is trapped on
the sea floor
200 meters below the surface after becoming entangled in an abandoned
fishing net. The vessel carries only enough air for 24 hours. Japanese
rescue ships are on the way but aren't expected to arrive in time. Russia
has asked for
help from the
US Navy's Deep
Submergence Unit which will attempt to air lift in the Super Scorpio ROV
on an Air Force C-5 in time to free the sub from the net and save the
crew. The Super
Scorpio robot can reach depths of 5,000 feet and
includes a cable cutter that cuts up to 1 inch steel cable. The ROV
also includes two manipulator arms capable of lifting 250lbs. The NavSource
Submarine Photo Gallery includes several photos of the
Super Scorpio ROV. For updates on the story, see Google
news.
As of 9am central time the sub is still stuck. The Russians have
managegd to attach lines to the sub and drag it about 60 towards shore
but it's still too deep. A Russian ROV has obtained video and it turns
out the sub is not caught in a fishing net but on antenna cabling that's
part of Russia's coastal monitoring system. A second Super Scorpio ROV
was sent from the UK and arrived a couple of hours ahead of the US Super
Scorpio. Both ROVs have arrived and were being offloaded to ships at
the last report. There are several conflicting reports from the Russians
on how much air is left in the mini-sub.
The British Super Scorpio ROV arrived on the seen a couple of hours
before the US Navy's Super Scorpio. The ROV successfully cut the sub
free of the cables it was tangled in. The sub was brought to surface and
the crew are all okay. There are still conflicting reports about what
exactly the sub was tangled in. First it was a fishnet, then a Russian
antenna cable system, then it was fishing line but no fishnet, and I've
seen several more recent reports saying it really did turn out to be a
drifting fishing net.
