how likely is it that a diver can cut an armored cable close to shore? without using explosives I mean...

Its quite easy with a Thermal Lance... http://en.wikipedia.org/wiki/Thermal_lance -- ~ Andrew "lathama" Latham lathama@gmail.com http://lathama.net ~
I'm trying to make sense of this.. - Welding Gear is expensive, underwater gear is insanely expensive. - Welding is pretty difficult.. - Underwater welding requires knowledge of SCUBA *AND* welding techniques under water. - There are 8 undersea cables located near the cable that was being cut. - There are a TON of EDFA's in the area, which are much easier to destroy. - Of the 8 undersea cables leaving Alexandria, only one was being tampered with? Does this not look like something that is either state sponsored, or someone trying to break a certain circuit? Obviously we won't know for some time what the circumstances were (if ever), but going after a specific cable with a welder sounds like someone had a real reason. And if this *WAS* state sponsored, I would be really curious as to why they did not use regular UDT guys with regular UDT stuff that goes boom under water. Not to mention the fact that they were using a welder, underwater, on a 15kV -48VDC fiber optic plant in dirty(ish) salt water - which sounds like a pretty bad idea.

Warren: I think I missed a step here. Where is the reference to the welding equipment coming from? The photos show three scuba tanks and a float. I don't see any mention of welding equipment in the NYT or Guardian pieces, or in the Egyptian Navy's statement or photos. -Bill

Thermal Lances can be started with various heat sources. Some are self contained for emergency use. On Mon, Apr 1, 2013 at 1:04 PM, Warren Bailey <wbailey@satelliteintelligencegroup.com> wrote:

either way, there's no mention of such a device in the reporting... or picts. right?

The oil services industry has rather frequent application for cutting metal objects under-water. http://www.csunitec.com/saws/reciprocating_hydraulic.html

sure, if you want to hang around and see the cut and perhaps do something about it... if you just want to drop-and-go... wrapping the cable in a pound/half-kilo of semtex/c4 will do fine. I'd expect 'alquaida' type folk to have easier access to explosives than a thermal lance as well. -chris
