It is entirely possible for there to be two (or more) ships of the same name.
As noted elsewhere in this thread, there was a ship that carried the name EXAMINER between 1928 and 1941, at which time she was renamed EXCELLO. She was sunk in 1942.
But see http://shipbuildinghistory.com/history/shipyards/1major/inactive/bethquincy.htm and scroll to hull number 1484. This ship was also named EXAMINER. She was a class C-3 cargo ship, built in 1941 and scrapped in 1970. So, obviously, she was not the EXAMINER/EXCELLO that was lost in 1942 and may very well have arrived in New York in 1943.
It is possible that the second EXAMINER was owned by the same company that owned the first ship of the same name. The first EXAMINER was renamed in 1941, which often happens when a ship is sold. So, to speculate, the shipping company may have sold the first EXAMINER in 1941 (at which time the new owner renamed her) even as a replacement ship was being built for the first company. I find many examples in my research of a given shipping company owning two or more ships of the same name over time, although obviously not at the same time.
Or the fact that two ships had the same name might be coincidental.
See http://en.wikipedia.org/wiki/Type_C3_ship and http://www.usmm.org/c3ships.html for general information about class C-3 cargo ships.
Hope this was helpful.
