Will the corporations who stand to benefit from LNG, take control in the Haynesville to limit or curtail development in the Haynesville?
Will they flood our markey to keep the price NG price low, so it is cheaper to import than to drill?
Will they CYA and their interests?
Would they buy interest in companies that drill here to slow them down as the partner that wants 'to wait'?
I read something, saying there is enough demand for the imports and drilling, is this true?
Do you have any further information on this event? Link, etc.? I recall reading articles in the general press when LNG tankers were first noticed out side of the industry In the early 90s? The articles always closed with comments about how much energy would be released if a tanker blew up. The magnitude of the potential explosion was always in the nuclear weapon range. After reading some of the information given at sesport's link, they must have arrived at the numbers based on the yield if all the LNG was vaporized and had an optimum air/fuel ratio mix. Still not pretty.
Mac, please just consider some of these mitigating factors:
- LNG tankers are not under pressure, so release rate is not the same as a pipeline rupture.
- LNG is a liquid so any spillage rate is slow and as vapors form they dissipate quickly.
- LNG tankers have double wall construction which is more protective than pipeline's construction.
- Methane is lighter than air as opposed to LPG which is heavier than air.
- The leakage is not in a confined space such as a house.
- Most LNG receiving terminals in the US are in remote areas away from population centers.
The industry recognizes the hazards which is the reason for rigorous safety standards for the design and operation of tankers and receiving terminals.
LNG tankers move and can hit rocks or other ships get caught in hurricanes, etc., so there's some risks that aren't present in a pipeline.
I'm not entirely convinced about the "lighter than air" argument. Yes, lighter than air is a good thing, but Nitrogen is 13% lighter than oxygen, but we don't end up with pure oxygen at the surface, and nitrogen aloft. Even though the methane will tend to dissipate upwards rather than run along the ground, won't some of it still be near the ground? Especially if the methane is coming from cryogenic liquid methane and is colder than air.
Spillage may be slow if there's a small leak, but not for a major rupture of the vessel. Also, there's a lot more methane in a given volume of LNG than for a given volume of gas from a pipeline. What happens if an LNG tanker sinks or rolls over and ruptures the tanks, and water gets in, boiling off some of the LNG, creating more pressure, squirting out quantities of liquid LNG into the water, where it will flash boil?
Remote area is nice, but they could be off-course due to storm or terrorism. I wonder if we have the gumption to sink an LNG tanker if it starts heading for a populated area by accident or unknown reasons. Suppose terrorists take over, and then claim that they're having mechanical trouble or simply don't respond. Do the LNG tankers pass close enough to get to a populated area before we'd decide to sink it?
Somalia shows us it's not that difficult to hijack a mega tanker.
I'm not really that concerned about LNG tankers. (Hey, I live 200 miles away from the ocean.) However, I have my doubts about some of the reassurances.
Mac, the bottom line - it is just not that easy to rupture or pierce into the actual LNG cargo container for the tanker because it is double-hulled plus has a lot of insulation space. Some heavy duty technical studies (Sandia Institute) concluded it would some type of rocket launcher to actual pierce a hole into the cargo. There would be no explosion but rather a small hole. Hence my slow leakage example.
Terrorists are far more likely to go after a crude oil, gasoline or LPG tanker or maybe a ship carrying fertilizer. Check Texas City disaster.
Thanks, Les B. lent me his "library card." lol My POV is that the HS play is going to influenced by local, national and global factors. I'm not an "expert" but I do try to take all influences into account.
Martin - I have to be honest here ... Les B. didn't actually "lend" me his card, I kinda "borrowed" it ... all right "hijacked" it. Geez, I put it back before he even noticed, not like I was going to keep it.
As exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond. This site was born out of these desires. Before we started this site, googling "shale' brought up little information. Certainly nothing that was useful as we negotiated a lease. Read More
