110 COLLAPSE OF TEXAS TOWER NO. 4 



B, taking the proper precautions and after considering our estimate of 

 cost, we submitted a tender. 



Senator Saltonstall. I am not informed what scheme B is, but 

 I assume that is what you have just described? 



Mr. DeLong. Scheme B is where we floated out the template in 

 upright position, which was all welded, and sank it down on the 

 ocean floor. 



Senator Saltonstall. I have one other question. Do I understand 

 from your testimony that the fault was not in the design, but in the 

 method of installation and that the resulting damage came from the 

 installation ? 



agreement with design 



Mr. DeLong. No, the principle of design is not wrong, the 

 K-bracing. 



Senator Stennis. It is right, you say? 



Mr. DeLong. The principle of K-bracing using a triangle struc- 

 ture in deep water is practically the only economical way to do it. 



Senator Saltonstall. So your criticism is in the method of in- 

 stallation rather than in the design ? 



Mr. DeLong. The method of pinning, the bracing versus welding, 

 and a tipping of the tower, and the exposure of bringing a big plat- 

 form into the sea and trying to fasten it on the legs and raising it in 

 the air. 



Senator Saltonstall. So you would only proceed under what you 

 call scheme B, and not under the scheme of installation that was 

 recommended ? 



]Mr. DeLong. That is correct. 



Senator Saltonstall. May I ask one more question on physics ? 



Will the strength of the waves in the Atlantic Ocean bring greater 

 pressure on a tower of this kind than the strength of the waves, say, 

 intheGulf of Mexico? 



Mr. DeLong. No, I would say they are somewhat comparable. We 

 have had 55 foot waves in the Gulf of Mexico and a 150 mile an hour 

 hurricane at the same time. 



Senator Saltonstall. Mr. Chairman, I have no more questions. 



Senator Stennis. Thank you, Senator. The Chair proposes, with 

 the consent of the committee, to let Mr. Bauer finish his statement 

 now. Then we sliall have questions, first by members of the com- 

 mittee and then counsel will close on any points that have not been 

 covered. 



Mr. Bauer, you may proceed. 



Mr. Bauer. Well, I think that it has been pretty well covered. 

 What I had started to do is compare the two methods, and I think that 

 has been pretty well covered. 



Senator Stennis. Well, were there other points that you had in 

 mind that have a bearing on this picture ? 



Mr. Bauer. No, I do not think so. I think I have completed my 

 statement. 



Senator Stennis. All right, then. We may now address ques- 

 tions to each of these gentlemen. Frankly, between them, they have 

 covered tlie points that came to my mind during this hearing, and I 

 think their testimony is much clearer than some of the high-powered 

 prepared statements that we sometimes had to wade through.
