The scheduled date for moving the Structural Support from its existing storage position to the barge was given as December 7,1980, and this has now been accomplished.

The repair work is as described in our Specification 2BVS-45, dated October 10, 1980, and an uncontrolled copy of this Specification has been transmitted to Mr. Mattia via Mr. Varela in order that your office may establish the scope of the work involved and perform any initial review required.
