This is a late entry from last Friday. We have removed the relay tube between HAM5 and HAM7 and replaced it with the adapter/viewport assembly on the HAM5 side. The assembly is being pumped down independently by a small turbo/aux cart. The GV should not be opened until the pressure in the viewport assembly is approximately the same as the corner pressure and the aux cart is valved out.
The adapter's isolation valve was opened, then the adapter was leak checked, no leaks were found. Adapter and accessories will remain until we are given the OK to remove them.
