A Response to my Crabbing Sub Article
How neat is this, I get a response to a blog article and no one tells me… sigh. Whatever happened to ‘hey, wrote a response to your blog’? Anyway, I would like to thank the author of the response… he made me consider a few things and I’d like to respond to some comments he made.
First, here’s the response: http://kodiakkonfidential.blogspot.com/2007/06/wanted-for-deadliest-catch-2020-rocket.html
For some reason, I’m reminded of the Gary Larson cartoon where two cavemen are watching a third try to start a fire. One comments to the other, “You know, if fire were so great, someone would have invented it already.”
“But it’s not really the kind of industry that attracts Ph.D’s.”
True, but I’ve seen a lot of local industry (Petrochemical here) that has increased in sophistication dramatically without the increase in degree level for the employees. Nowadays, you can get a good job at a refinery (controlling millions of barrels of oil) with just a two year degree. As long as your trained with the technology, you don’t have to be able to create it, just use it. It shouldn’t be that much more complicated than the current technology used on crabbing vessels. Of course, a submarine has it’s own issues, but if the Russians can do it, then a bunch of guys from Alaska surely could.
“He suggests launching crab pots out of the rocket tubes from old Soviet submarines to avoid the dangers of topside weather.”
This is the critical reason for my idea. In one episode I watched, they talked about several sinkings some with no survivors. These guys are risking their lives so we can have crab night at Red Lobster. I’d like to see them operate and be safer.
“Of course all this has to be done in the dark and by remote control. You’d think if remote control was available, they’d be doing from a surface ship.”
Again, one episode they were talking about -40F degree weather. The crew would have to break ice off of everything on the boat for 4 to 8 hours, then they could work, then they broke ice for another few hours and went to bed. The equipment is available to work under remote control, but it doesn’t work well at a temp of -40. Men work much better at those temps.
Underwater however, the temp is only about 33-35F. Most of the underwater equipment will work fine at those (non-freezing) temperatures. Many submarines (and I believe the Delta IIIs that I mentioned in my article) are perfectly capable of breaking through light pack ice to reach the surface.
According to wave theory you only have to be half as deep as the wavelength of the wave to have zero effects from the wave. Ocean waves average between 40m and 400m (yeah, I know huge difference). But that means that from 20m to 200m, there are no effects on a sub from any surface actions. It’s warmer and calmer, therefore safer.
BTW: It’s two blue paradise gouramis and 4 neon tetras. And my son loves them so there 🙂
