The floor blast was scheduled to start 3-5-08, but was delayed due to cracks discover in weld seams in floor. This pushed the start date by to 3-11-08. Once ICC entered the tank it was discovered the original millage of the floor liner was not accurate. The original millage shown 15mln and the actual millage was 45mln. This change the process of blasting the floor and added 3 weeks duration to the overall schedule. The blasting was completed 4-15- 08. The tank was turned over to HMT on 4-28-08 (availability of manpower). The inspection was completed 5-22-08 due to the availabiltiy of manpower supporting for both A-416, F-502, and chasing pinhole leaks in floor of A- 416.The current path forward is to helium testing pontoons and PEI is working on repair plan.
