You can, if you're feeling brave, add some propane to the air intake
stream, which should - in theory - reduce the amount of diesel used (the
engine's governer will take care of it), but it's not an exact science,
and would very likely void the engine manufacturer's warranty...

You can't remove the diesel entirely, since you need something to ignite
the propane - compression alone won't do it.

Good way to blow up a perfectly good diesel engine.... Just look at what
the cause was of the Gulf Oil Spill on the Drilling Vessel. They had a
High Pressure (20K PSI) Natural Gas Blowout. That could have been
contained, except for, all that NG spread over then ship, and then got
into the Air Intakes for the BIG Diesel Gensets, that supplied ALL the
power for the ship, disaster, and Fire Pumps, and the Ship and Drill
Rigs Control and Computer Systems. The Gensets engines Ran Away, due to
over-fueled condition and destroyed themselves, and in that process they
blew every light bulb and motor on the Ship. When the Lights around the
Drill Rig exploded, it lit off the NG, causing the fire, and with no
Power to run ANYTHING onboard, there wasn't a thing that the crew could
do, but get off. The fire, ultimately, sank the ship, which caused the
Pipe to break off, and with no control over the BlowOUT Preventer, and
all that pressure coming up, the then, broken pipe, lots of Petroleum
products went into the water, and still is....

Our Capt. Tyler represented south coast fishermen during the dungeness
crab price negotiations this year for the first time. It was crazy. The
big buyers sent professional negotiators with lawyers and teams of people
while we had like five captains from up and down the coast. They did all
they could do to pressure and screw us over for a few extra pennies a
pound knowing that we couldn't hold out because a lot of boat owners had
payments to make and mouths to feed. It was pretty insane to see how
that process works when big money goes against small individual
businesses.

I believe that is why cooperatives, Blue Diamond and Sunkist come to mind, are
formed. No one should get screwed out of a living, but isn't likely that what
the fisherman saved by not having lawyers was more costly in the end?


However, I still do recommend the Honda Generator -- made by a giant
corporation :)

I am one of those retired local government workers you are talking about. My
retirement was financed both by taking money from my pay, and by direct
contribution from the city budget; BUT WHO CARES?. If you stop to think about
it, it really makes NO DIFFERENCE if they go through the accounting excercise of
putting the money in my pay account and then taking it out to finance the
pension, or just putting that same money straight into the pension plan. Either
way, IT IS THE SAME MONEY, and it is/was part of my compensation. I spent 38
years working for the taxpayers at less than the going market pay. Part of the
deal that kept me there was the promise of a modestly secure retirement. Unlike
many governments, my pension was fully funded and "in the bank" the day I
retired. The city's only future expense is if the pension fund's investments
happen to go bad.

I am shocked that some governments do not fully fund their pensions, leaving the
debt for future generations to pay, but let's not blame the workers for that!
Put the blame where it belongs, on the way us voters allow our local governments
to be mismanaged, and on our constant demand for for the impossible combination
of lower taxes (now!) combined with higher services (now!) and damn the future!

Ok guys, I checked out the Northern Lights generators.
I'd like to have one but I want $10,000 more. The one I'd
want is $15,000, I'm looking at spending $4 to $5,000.
So I see the Honda 6500 watt for $3,400.
I decided gas will not be a problem, we have warning
about hurricanes, my wife always fills up the vehicles,
So there's 70 or 80 gallons, (4 cars) I have a 70 gallon
stainless steel tank if I decided to put it to this use.
The Honda is a generator inverter, (more stable). That
was not my concern, even though I have 4 computers, I
could probably make it a few days without computer time.
My teen son, hmm. :)
My question is would the inverter (electronics) vs
a straight (mechanical) scare you away?
I'm thinking a Honda would be dependable either way.

Yep, that actually works. But seldom actually done.
Drain the carb bowl
Some engines these days have a special drain in the float bowl to help you do
that. Read the manual. There may be other storage instructions. Honda tells
you to put a tablespoon of oil in the cylinder and pull it through a few times
to fog the engine with the oil. Then replace the spark plug and pull the engine
through until you feel compression, now you know that both valves are shut!
and it'll start the next year.

Like I said, following the storage instructions works!

I use Stabil and usually keep the gas about 18 months (Through two hurricane
seasons) After that, I burn it in my Accord and it always runs fine. Always
write the vintage date on the can so I don't screw up. However...I found a
5-year-old can of treated gas hiding in the back of my shed. More than a gallon
had evaporated, but the rest ran just fine in my lawnmower.

Frankly I doubt what you say, if for no other reason then that the
guys most intimately involved, the drillers and the floor crew are all
well aware of what will likely happen to them in the event of a blow
out. And it did.

Another point is that before drilling in U.S. waters there a lot of
regulations that must be complied with: Here is a part of a e-mail I
received from a friend who is a Rig Supervisor (company man) in the
off shore drilling business:

quote:

Any oil company operating in the USA deals with governmental
regulations, similar to Indonesia but much more strict. They have to
be a bona fide company to acquire a lease to explore on. PT
Holeinthewall would definitely get turned down. Then before they
drill, they have to submit their plans to a government body called MMS
(Mineral Management Service). It used to be the USGS (United States
Geological Service) but MMS was created about 1982, when I was in the
US taking some seminars in Texas and Louisiana. Although they have a
lot of dead beats working for them, much like any government
department, that drilling program is well screened and scrutinized
before an oil company can start drilling. Any changes to that drilling
program have to be approved first. During the drilling, MMS does
'surprise' helicopter trips to rigs to check to see if the required
casing, BOP, drilling equipment has been tested before it's tested
expiry dates. They are serious! I did a well control school in
Lafayette and a lot of the questions on the exam pertained to US rules
and regulations. Didn't mean anything to me because I was never going
to work in the USA, but I had to memorize them to pass.

Unquote:

You will notice that there has been no mention of the MMS in the
president's news announcements.

This is not to say that there were no mistakes but I doubt that it was
the drilling crew that deliberately made them and the government was
responsible for oversight, and likely did carry out the inspections
that were required.

It doesn't seem to have gotten much mention but the US does have an
organization that regulates and controls oil drilling. Called the
Mineral Management Service you can goggle it at
http://en.wikipedia.org/wiki/Minerals_Management_Service among other
spots.
The section titled "Role in 2010 BP oil spill" is quite enlightening,
considering the presidents publicity campaign.

I worked in the business for quite a few years and you need to
remember that anything in and on the well is a certified device that
meets some standard, whether government or certifying society. Thus
casing, well head devices whether christmas tree or BOP all must be
made to the same standards and there are relatively few companies in
the business so prices are much the same no matter which make is
selected.

The US government MMS (Mineral Management Service) also approves the
individual items that go into the well. The whole business, in the
U.S. is highly regimented and controlled by the MMS. Well schedules
approved, surprise inspection visits conducted, inspection of both rig
equipment and materials used in the well.

Reads like a lot of wild speculation. Engines trip on overspeed long
before they tear themselves apart. That shuts off all the fuel. Many
such large engines also have air intake shut offs that trip shut to
prevent run-away on lubricating oil, so they would also shutdown on NG
at the intake. Such trips are designed to prevent the engine from
'tearing itself apart'.

Replace all the fuel oil supplying an engine (by tripping the fuel
racks) with a very improbable 'perfect mix' of NG and air and you get
less power, not more.

In order to 'destroy' all the motors on the rig, you would have to
provide voltages several times their rating. Even a run-away engine
can't do that generator regulators are better than that. At most you
might get 120-140% of rated voltage.

In real life when you apply overvoltage to an incandescent light it
doesn't explode in a shower of sparks like the movies, it just gets
brighter, flashes and goes out.

Much more likely the gas explosion is what stopped the engines. The
reports of survivors was that they felt/heard the explosion and that's
when the lights went out. No one reported lights blowing out before the
explosion.

There have been several insights into the failure of the blowout
preventer, none of which hinge on your 'loss of power' statements. The
wrong diagrams and some change that caused the test ram to activate
instead of the correct one.

Where did you get this 'scenario'? Sounds like you just made it up.

The same goes for social security, Many, many retires collect 3, 4, 5 and
more times money than they ever paid in,
When social security started the average life span was 63 and benifits
started
ar 65, that systen worked, now we live till 75. The system no longer works.
Also many retires paid only 3.25% of their wages when they started, today
it's double at 6.2%. I'm self employed and pay 12.4% + 2.9% medicare. 15.3%
of
my money goes into the system to pay those that didn't pay enough to cover
their retirement. My money is not being saved for my retirement. I can't
imagine my children paying double what workers pay to day when they
are nearing retirement tp cover me. That would be 12.4% with their employer
paying the other 12.4%. If they're self employed that would
be 24.8% + medicare of 5 8% for a total of 30.6%. The system is
broke and a some point it will collapse. Oh and don't forget regular
income taxes on top of that .Government needs to let the people
take care of themselves.

Actually this was all stated by the Chief Electronics Tech, who was on
the vessel at the time of the blowout. Most BIG Gensets do not have Air
Dams if they are 4 Stroke Engines Those are common on the Detroit
Diesel 2 Strokes, but they (Detroit Diesels) don't even come close to
the size of gensets onboard this vessel. LubeOil Runaway is a Two Stroke
Diesel Phenomenon, 4 Strokes don't do that.

Yes, but that has to do with *How Well* pensions are funded, not where the
actual dollars come from to do the funding. It really makes no difference if

pensions should be funded from TODAY's budget, not left for future generations

Any outside source of fuel may cause a diesel engine to run away.
Actually not unusual on drilling rigs, they get a little gas bubble
and the engines speed up and then go back to normal. Detroit Diesels
were famous for it, a blower seal would fail allowing lube oil into
the induction system and away they go. Whether the rack is open of
closed has no effect if the engine is running on an alternate source

No, what was said to happen was that the kick blew enough gas into the
engine room and mud pump room to make the diesel engines run away and
then burst. An instant loss of generators and electrical power.
Possible that started the fire and possible it was something on the
rig floor banged against something else and made a spark.
There have been several insights into the failure of the blowout
preventer, none of which hinge on your 'loss of power' statements. The
wrong diagrams and some change that caused the test ram to activate

I believe that the BOP had two different systems, electrical and
hydraulic as well as several redundant systems. BOP's are normally
tested periodically and a record is kept of the results on most rigs.

And even if the rig crew were so slack that they didn't test the
system - which is pretty far fetched as the drilling crew is well
aware of what is going to happen to them (and it did) if they need the
BOPs and they don't work - the MMS makes frequent visits to the rig
and BOP checks are one of the things that they check for.

In addition all of the larger offshore rigs and probably most of the
small ones have real time video all over the place and certainly on
the rig floor and the home office does watch what is going on out
there. and calls up on the satellite phone to bitch about things.

Since, as far as I know, oil is flowing out the riser which means that
the BOP's probably didn't close, or only partially closed, and my
guess is that if they ever get the well killed that they will cut the
BOP stack off and recover it as if the BOP's themselves failed then
both the oil company and the drilling company will go after the people
that made the BOP's.

That's why I mentioned that I've seen many engines that have air-intake
shut-offs. When running on lube oil, tripping the fuel rack does
nothing, just as you say. But tripping the air intake shut starves the
engine of air and it would stall.
I don't believe anyone ever intimated that the "motors" failed. The

Well perhaps the statement 'blew every light bulb and motor on the

claiming the motors 'blew' in some way.

One article said that BP and the rig owner were arguing about the
diagrams and that some alteration had been made to the BOP. When they
connected to the BOP to activate the ram that would kill the flow, they
only activated a test ram that had little effect on the flow. Both
sides argue that the change shouldn't have been made without authorization.
http://www.mcclatchydc.com/2010/05/12/94067/oil-spill-bp-had-wrong-diagram.html

Another pointed out that at the extreme pressures involved, bits of rock
may have eroded the BOP plugs as they started to shut off the well,
causing them to leak.
http://www.theoildrum.com/pdf/theoildrum_6421.pdf

But I haven't found any article that blames the BOP failure on a loss of
power as '[email protected]' claimed. The articles I found agree with you
in stating that they have redundant power to operate (and both manual
and automatic shutoffs). Even after the initial explosion/fire, the
attempts to activate it directly from the sea floor failed. So the
scenario of losing the diesel generators prevented the BOP from
operating seems to be pure fiction on '[email protected]' part.

I'm looking for a real breakdown of diesel vs. propane, in the

some # of hours, below which propane wins and above that, diesel does.

I need to be able to quantify that. Has anyone seen a case study?

engine room and mud pump room to make the diesel engines run away and
then burst. An instant loss of generators and electrical power.
Possible that started the fire and possible it was something on the
rig floor banged against something else and made a spark.


I believe that the BOP had two different systems, electrical and
hydraulic as well as several redundant systems. BOP's are normally
tested periodically and a record is kept of the results on most rigs.

And even if the rig crew were so slack that they didn't test the
system - which is pretty far fetched as the drilling crew is well
aware of what is going to happen to them (and it did) if they need the
BOPs and they don't work - the MMS makes frequent visits to the rig
and BOP checks are one of the things that they check for.

In addition all of the larger offshore rigs and probably most of the
small ones have real time video all over the place and certainly on
the rig floor and the home office does watch what is going on out
there. and calls up on the satellite phone to bitch about things.

Since, as far as I know, oil is flowing out the riser which means that
the BOP's probably didn't close, or only partially closed, and my
guess is that if they ever get the well killed that they will cut the
BOP stack off and recover it as if the BOP's themselves failed then
both the oil company and the drilling company will go after the people
that made the BOP's.

That's why I mentioned that I've seen many engines that have air-intake
shut-offs. When running on lube oil, tripping the fuel rack does nothing,
just as you say. But tripping the air intake shut starves the engine of
air and it would stall.


Well perhaps the statement 'blew every light bulb and motor on the
Ship...' was misleading then. It sounded to me like the poster was
claiming the motors 'blew' in some way.


One article said that BP and the rig owner were arguing about the diagrams
and that some alteration had been made to the BOP. When they connected to
the BOP to activate the ram that would kill the flow, they only activated
a test ram that had little effect on the flow. Both sides argue that the
change shouldn't have been made without authorization.

Another pointed out that at the extreme pressures involved, bits of rock
may have eroded the BOP plugs as they started to shut off the well,
causing them to leak.

But I haven't found any article that blames the BOP failure on a loss of
power as '[email protected]' claimed. The articles I found agree with you in
stating that they have redundant power to operate (and both manual and
automatic shutoffs). Even after the initial explosion/fire, the attempts
to activate it directly from the sea floor failed. So the scenario of
losing the diesel generators prevented the BOP from operating seems to be
pure fiction on '[email protected]' part.

Yes, but that has to do with *How Well* pensions are funded, not where
the actual dollars come from to do the funding. It really makes no
difference if you first hand the money to the employee and then take it
back! I agree, pensions should be funded from TODAY's budget, not left
for future generations to pay.


Yes, but others die before they collect a dime. Properly designed,
everything is supposed to average out and the system is supposed to work.



I don't disagree, but the discussion was about local government pension
systems.


How far are you willing to go with that concept? Are you willing to see
retirees starving in the streets?

No but how many people were staring in the 50s, we had a lot less taxes
and
regulation.
Also if the government gets out of the way we have organizations that will
help the poor.
We would have more of these if the government didn't interfere, and they are
closer to
the situation, not just the government give your and my money to people who
don't deserve it.

We get the government we deserve. Ultimately, it is up to the voters, but
voters do not tend tp be long-term thinkers, so the politicians do what
gets them elected and keeps them in office. So we end up with the
government we deserve.

Did I remember to mention; we get the government we deserve?

Vauhn, I'm working hard to change what we have now. The leadership is
going down the road of European socialism. This is America, we are
different,
we believe the people give government power, not the reverse.
Our forefathers devised a great plan along with capitalism, that created
great wealth, the poor in America have cellphones and cable tv and drive
cars
the kids have video games and two tvs..
The poor in many countries have mud huts and lack of food.
Makes it difficult for me to feel sorry for poor Americans.
There is so much opportunity here that we can't keep people out!!!!
I'm married into a legal immigrant family. They came hear with nothing,
very little english, but here because there is oppurtunity. They have worked
hard for 30 yrs. My wifes brother and sister are millionares, another one
brother and
sister are doing good but don't have a million. Now their children 3
pharmasists,
at over $100,000 a year, one $175,000. One child is chemical engineer,
Don't know exactly but he just got a raise of $35,000, ya that's the raise
only.
He's well over $200,000 a year. There's more to tell but you get the point,
education was the key to all of the children. Hard work and many hours for
the parents.
I'm a bit jealous, but they deserve all they have because they worked and
earned it.
The freedom we have is slowly being taken away. Help save America.

If you want to worry about the poor, poor health is a reason to be poor,
My father had a bad heart attack at 43, It was tough and he had help,
but a healthy person can work and not be poor.

I see many people who would rather get a government check than work.
If they are healthy, they should be forced to work, at least to get the
check there
should be large room where they go 5 days a week for 8 hrs and sit. Then on
Friday, if they made all 40 hours they get there check. I bet welfare rolls
would
drop quickly. Another thing, unemployment, when the max benefit is six
months
amazing how jobs are found in the 5th month, when benefits are lengthened to
1 yr, jobs are found in the 11th month.
I know, it's human nature, government needs to be aware and design programs
that bring out the best in humans, not the worst.
End of rant for now, I have work to do, did I mention we are open 10 hrs, 7
days,
363 days a year. Well ya gotta rest sometimes. Thanksgiving and Christmas.
