Heh. Check out their latest groundless claims: '1,200 "Palestinians"

That could be the case.

Obviously training altered slightly after PA but the basics were
proved to be correct and quite a few people owed their lives to those
boring hours in the swimming pool.

One of the guys I work with was on Cormorant Alpha when it had an
unplanned shut down and he reckons he was going up a ladder as fast as
he could when the gas plug (1) that failed went screaming past him at
one hell of a rate of knots.

Apparently everyone was waiting patiently on the operations deck when
a series of loud bangs that shook the deck were heard and at that
point they all piled onto the helicopters as fast as possible. North
Sea rumour (2) has it that one of the evacuees was told to get out of
the seat he was sitting in on a helicopter and when he refused he was
told by the co-pilot that it wouldn't fly if the co-pilot was standing
up.

(1) Supposedly a safety measure implemented after PA. The person who
told me the story also reckons the overtime earned on this work paid
his mortgage off 10 years early.

(2) The same person that had the plug overtake him.

 

Moving water mixes. Water (pure) is at its densest at +4C, so what
floats is either warmer or colder. If the surface is colder and the body
of water is moving, then the motion will bring warmer water up to the
surface.

 

I've seen an experiment done on the TV Christmas lectures. (OK I know
it's for kids but they're good to watch.) They took some 'super clean'
water down to well below 0 deg C and it hadn't frozen.

The guy then struck the side of the glass beaker and you could watch it
freeze in a couple of seconds.

 

Having spent quite a long time bobbing up and down in the North Sea in
conditions that the Met Office, Inshore Waters Forecast, calls Calm
Smooth Slight, I would not like to jump into anything rougher.

Mmm? I watched that programme too.

It went something like:

Those who didn't follow the evacuation procedures to go to the
evacuation points survived. They realised that, that would take them
into further danger and looked for an alternative escape route.



[1] *WARNING ANECDOTAL / HEAR SAY COMING UP*

From when I lived near the ports and having known a few of the people
working on the cross channel ferries, who also have to do in pool and in
sea training. I was told by them:
"After the 7 danger signals, don't necessarily go to a muster station.
If you see a member of the crew running like mad putting on a life
jacket, follow him. He knows the fastest safest way off of the ferry."

 

Another neat trick - take a cup of water/ice slush at 0C,
stir in a couple of teaspoons of salt, and watch its temperature plummet.

But back in the real world where water is not so pure,
fresh water freezes at 0C and sea water freezes at -2C,
whether it's moving or not.

Roger.

 

Eventually, yes. But moving water takes a lot longer to freeze. So it's
perfectly possible for a fast flowing salt water river to drop well
below the freezing point of still water, & not have time to freeze
before the temp goes up again.

I've seen something weird like that happen once. I'd put some cans of
Red Bull in the freezer to cool them down quickly, then forgotten about
them. A few days later when I remembered, I got them out of the freezer,
opened one and poured it into a glass. It went in as a normal looking
clear liquid, but by the time I'd finished pouring the glass it had
transformed into a gloopy, slushy puppy like, sludge.

 

You'll need to provide some evidence for that if you expect anyone
except Tim to believe you.
Got any URLs for dodgy science sites?

 

I'm sure you know how to Google - plenty of sites out there saying the
movement causes the molecules to break apart, delaying the formation of
ice until the flow's slowed down enough.

To take it to extremes, are you saying that a 1000 foot waterfall would
instantly turn to ice as soon as the water temp hit 0C?

A different case entirely. Ice and water (fresh) coexist at 0C.
You need to take a lot of heat energy out of the water at 0C to get ice
at 0C.

 

You could start here http://www.weather.org.uk/resource/ukswxfaq.htm as
well as anywhere else.

A large body of water has a lot of stored heat to get rid of before it
freezes.

And this eventuality isn't covered in the basic off shore training?

 

Of course it is that's why they survived.
They thought outside the basic rigid rules.
They knew what the best option was because they understood the layout of
the rig and how they could survive. All part of their training but not
following the rules.

 

No they didn't.

You've let yourself be influenced by a BBC programme but one very
telling point is that said programme has no part in offshore training.

I can't be bothered trying to find documentation to prove to you
exactly what all staff are told to do in an emergency but nobody is
told to go to one place no matter what happens.

 

OK I accept what you say. My only source of information is from a BBC
programme, a channel 4 thing and a Sky TV at disaster programme which
all said the same thing, they were told to go to the drop boats or to
the heli deck. This is not to say the programme is correct, being
produced by the TV system they probably based each programmes content on
what the other programmes said.

 

But weren't the engine fire control switches linked to tthe wrong engine on
that plane? I seem to remember the "Hero - oops - dickhead" routine was
followed by some mention of the switches not doing what they should.

It's rarely otherwise.

I did the same with some 1664 lager years ago. A small amount of liquid
came out before the slush. The very alcoholic liquor tasted quite nice. The
slush was horrible. I let the other 3 cans thaw out and gave them to my
teenage foster brother...

 

A local pub near me had my favourite beer, but it wasn't the local
beer and I was the main culprit for drinking it. So it sat in the
fridge longer and they had the fridge temperature set so low it was on
the edge of freezing. The beers looked fine until you opened the
bottle and the sudden pressure drop meant when the impact of pouring
meant I ended up with a beer slushy 50% of the time and they had to
get me another one. It took a quite a few months of wasting beer
before they turned the fridge up by 1°C to prevent it happening.

On the same theme, I seem to recall when doing my dive training that
we were told that seawater wouldn't go below 4°C. After that it needs
an energy loss to do the phase change to ice. I remember talking to a
guy who was going to Antarctica to dive and he asked around and said I
was right. This was in the early 80s. Has there been a change of
theory or am I mixing up seawater and fresh water?

 

Reading reports of this in the weekend paper, I eventually found out
about the Ditch Button. I didn't realise it was all so easy - no
power, losing altitude, over water, press Ditch Button and hey presto!

I also liked the letter in Saturday's Indy (c&p):

"The Government now has an obvious solution to the intractable new
runway problem. Immediately west of the two existing runways at
Heathrow are three very large reservoirs. Now that Capt Chesley
Sullenberger has demonstrated the feasibility of landing on water in a
built-up area, there can surely be no reason to press ahead with new
tarmac.

Instead, simply build a couple of terminals capable of handling
seaplanes next to the reservoirs and convert about a third of major
airlines' fleets. Lots of jobs, without the destruction of villages and
livelihoods. The leisure craft that currently use the reservoirs will
have great fun dodging incoming aircraft as well."
