120 DECOMPRESSION COMPLEX 



The PTC was completed and shipped via truck on July 23. The DDC was completed and 

 shipped via rail on July 29. 



Upon arrival of the PTC and DDC at Long Beach, a number of modifications were made. 

 The emergency release mechanism was tested and, after slight modifications, found satisfac- 

 tory. No need was found for its actual use during operations. 



The decompression complex was then installed aboard the support vessel and final check- 

 out tests performed. 



During decompression of the three teams, the only unusual operation occurred during the 

 decompression of Team 3. At a depth of 23 ft Master Diver Sheets reported pain in one leg. 

 Subsequently, Captain Bond entered the chamber via the outer lock, inspected Sheets, and re- 

 turned. Hospital Corpsman Manning thereupon entered the DDC, to stay with Sheets during his 

 decompression. The other nine aquanauts were moved into the 6-ft outer lock to continue de- 

 compression to the surface at 6 ft/hour. Sheets was "sent back down" to 60 ft, given O2 treat- 

 ment, and decompressed at a linear rate of 4 ft/hour.
