Q Did you ever use Lloyds?
2 A
Yes.
I an a little familiar with 3
Lloyds.
Yes.
4 C
Did you use Lloyds in-perf orming or 5
comparing the calculations with respect to the Shoreham 8
diesels?
7 A
In this case, we used the Gersan code.
8 0
What 's the case of the Ge rma n cod e ?
9 A
Well, it's a code which is used in --
10 inside of the German companies and which is accepted by 11 most o f the European companies.
12 0
What is the name of this code?
13 A
It has no special name.
14 Q
Just the German code?
15 A
It's a German code.
I can give you the 16 liters ture if you want.
17 Q
So you did not use --
18 A
It's published.
to C
You did not use Lloyds?
20 A
No.
21 Q
Did you use ABS rules?
22 A
No.
I followed up what has been done ALDERSoM REPORTING COMPANY,1NC.

Shoreham diesel engines, is it fair to say that you 2
relied on the German code and not on any of the other 3
classi fication society codes?
4 A
Not relied.
This is not relying, but it 5
is jus t -- you ask me for side calculations, and I said 6
we did this.
30t cur main task was to work through and 7
to arrive at a safe model of calculating.
For instance,
8 a crank shaf t at FAA.
This was done by FAA.
We 9
contributed scae ideas.
I think the final version cf 10 it, th e final results, we can back it up.
11 C
I'm just trying to understand. With 12 res par t to the anslysis calculations that ycu perforned 13 for the Shoreham engines, did you use the German ecde 14 rather than Lloyds, ABS, DEM A recommendations or any 15 other classification society code?
16 A
Well, this is just routine.
If we have 17 to dasion an engine or we have to assess an engine, by is routine, we have these codes and we do this.
19 Q
! understand.
Ycu don ' t -- I just want 20 to as:te sure I understand your answer.
21 Your answer is that you used the German 22 code?

Under the German code, do the Shoreham 3
diesel engines satisfy the requirements of the German 4
code?
5 A
It's just on the boundary.
If you ask me 8
tha t w ay, if I would design a crank chaft in Germsny for 7
this angine, it would be a little thicker.
8 C
A little thicker?
9 A
Not only of this engine.
Of others, 10 too.
It is a f act that is known in the -- well, under 11 engine manufacturers, this is a more conservative ccde.
12 Maybe it will be given up one day.
13 C
I understand you think the German code is 14 more conservative than any cther code.
15 A
It's a fact.
18 0
Dr. Pischinger, with respect to ycur use 17 of the German code, was it just with respect to the 18 crank shafts, the replacement crank shafts?
19 A
' Jell, this is one of the main topics.
20 Q
I understand.
My question is a little 21 b ro ade r.
I want to make sure we were on the same wave 22 lengen.
I asked if under the German code, the three ALDER 8cN REPORT 1NG COMPANY,INC.

different engine practices throughout the world.
2 C
Your calculations under the German code 3
with respect to the replacement crank shaf ts at 4
Shoreham, were those calculations performed at 5
horsepower rating cf 3500 kw?
6 A
Yes.
7 Q
Did you perfcra any calculations at the 8
3900 k w ra ting?
9 A
Yes, but this needs some input which we 10 had n' t had in this case.
11 Q
Let me ask ycu first --
12 A
We estimated it.
13 Q
With respect to your estimate at 3900 kw, 14 do the replacement crank shafts meet the German design,
15 cade?
16 A
No continuous ra ting at 3900.
It wculd 17 not be allowed.
to C
It would not be allovad?
19 A
No.
20 C
so, in other words, the code var not met?
21 A
No.
It was not met.
Yes, it was not me t.
22 Q
At 3500 kw, that's where, u er your AL.D074 tom PSPofmMG CCMPANY,INC.

calculations, the replacement crank shafts f all on the 2
bounda ry of satisf ying th e requirements of the German 3
codes is that correct?
4 A
Yes.
5 2
Have you, since performing your calculatien--
6 A
I have to say, with regard to side 7
calculations, if I would have really designed the 8
change, then I would put a lot more work in it.
It was 9
the first information we had f rom here, we did these to calculations, only some prelisinary calcula tions.
11 You cannot -- you should no te this.
You 12 ca nno t take this as a final statement here.
13 Q
Cid you ever perform the final calculations 14 under the German code for the replacement crank shaf ts ?
15 A
No.
16 Q
Why not?
17 A
Because we pursued this way which is a 18 lit tle scre elaborate and takes into secount -- it 19 takes into account the situation in Shoreham.
20 It's a unique situation.
You have failures 21 of three cranks shaf ts af ter a given time, and this is 22 a unique situation to use the knowledge of these l

weightier crank shaf t?
2 MR. STROUPEs You asked a sinimum, I believe.
3 Q
An I misstating what you told me earlier?
4 A
Maybe according to the German codes the S
shape of the crsak shaf t would be a litt e different, 6
but it would still be 13 -b y -11.
7 Q
13-b y -127 8
A 13-by-12.
We are tricking ourselves with 9
these flouces.
10 Q
Would it be a heavier crank shaft under the 11 German code that you'd want to see?
12 A
Not heavier.
13 Q
When you say the shape would be different, 14 how would the shape be diff erent?
15 A
Well, the German crank shafts usually have 16
-- it 's du e to the special code -- a little thicker 17 webs.
It means even smaller bearinos.
1a Q
Now, th e repiscemen t crank shaf ts were 19 designed by TDIS is that correct?
Do you know?
20 A
Yes.
They have been existing fo several at times before they were now installed in the Shoreham 22 plant.

I think we just talked on this topic.
2 Q
Can you tell me what was the Tn value you 3
use d?
4 A
You mean the tangen tial force?
5 3
Yes.
6 A
I do not kncw it by heart.
7 Q
Do you know if the values were supplied to 8
you or FEV by the Failure Analysis Associates or by TDI?
9 A
What I can tell you is that values which are to used in the report, final report by FAA, values which 11 are ve ry reasonable, which we can back up.
12 3
You used the values which were in the crank 13 shaft report?
Is that what you're saying?
14 A
I do not know if at that moment -- because 15 we did these side calculations, preliminary side 18 csiculations at an earlier stage.
17 So, in this stage we used some estimates.
18 Q
Did you use any German Tn values?
19 A
Well, if you are designing an engine, a
comple te new design, and you have no measured values, 21 the only, possibility is to make guesses.
And there are some rules for such guesses.

Dr. Pischinger, is it f air to say that these S-areas regarding fretting of the piston skirt and 6
scuffing of the piston rings and any recessendations 7
which you or Emilure Analysis Associates might have in 8
this regard, will be set forth in some later report?
9 A
Yes.
10 Q
When do you expect the release of that 11 report?
12 A
I think very soon.
13 Q
Dr. Pischinger, let me.1ust make sure I have 14 an unterstanding which is correct.
15 During depositions, other depositions in 16
.this rase, some individuals have noted th a t 17 prelim inarily you concluded, that the cyclic stress for 18 the re placement crank shafts were too high.
19 A
What stresses?
20 Q
The cyclic stresses.
21 A
Cyclic?

5 Q
This is an area,I believe we talked about 6
earlie r today.
7 A
Yes.
8 Q
What you told me is that you have not e
performed any final calculations in this regard?
10 A
No.
11 Q
Is it still your conclusion, Dr. Pischinger, j
12 that ander the German code, the cyclic stresses for the l
13 repiscenent crank shaf ts are too high?
l 14 A
Yes, if I regard it as a new design.
But 15 the situation here is completely different.
You have 16 here a designed crank shaft, the 11-by-13, which she wed 17 clearly pronounced f ailure at a time which can be 18 af fixed very exactly.
This gives you a base for a much 19 secura calcula tion of a new crank shaft.
20 You unually do not have this base if you 21 design a new engine.
Then you have to take a 22 conservative approach.

Q Are you saying design codes are only useful 2
when there is a new design?
i 3
A I wouldn't say only, but I say are used fer l
4 a new design.
That's the main purpose.
The main
(
purpose for a new design where you have no tests, no 6
strain gauge measures, nothing.

Are you saying, Dr. Pischinger, that when 8
you ha ve an engine which has operating experience, the 9

Cf course.
The most accurate way of 12 assessing design is to measure the physical design and 13 p ra cti c e.

Does the operating history of the 15 Transamerica Delaval R-48 engine provide you comfort 13 with respect to reliability and adequacy of the engine?
17 A
We dis =ussed this also with TDI people and 18 v e go t a list of generator, diesel generator sets all 19 over tree world.
Also figures on running hours of these 20 sets.
21 There are certain, rather bread background 22 for this type of crank shaf t and this type of engine.
