From what I can find, SS PHILIP SCHUYLER survived the war. The ship was constructed in 136 days between November 1941 (note: before the war began for the U.S.) and April 1942 by the Oregon Shipbuilding Company, Portland, OR. After the war she was likely placed in the reserve fleet ("mothballed") and probably never sailed again until being scrapped in New Orleans in 1967. See http://www.shipbuildinghistory.com/history/shipyards/4emergencylarge/wwtwo/koregon.htm (scroll to hull no. 184) and http://www.mariners-l.co.uk/LibShipsP.html (scroll to the name of the ship).
You may wish to obtain your father's complete military service record, which presumably would give his shipboard assignments. If you find he was aboard other ships you could research them as well, or come back here for questions. See http://armed-guard.com/searchmil.html, particularly section II.A.1 - Records of Individuals - U.S. Military. You will have to contact the National Personnel Records Center in St. Louis, MO and provide as much identifying information as possible.
If you're interested in a photograph of PHILIP SCHUYLER or any other ship, see this list of sources of photographs of World War II-era merchant ships: http://www.usmm.org/photosource.html. PHILIP SCHUYLER was a Liberty ship, so Mr. Hultgren, first name on the list, would be your best bet, in that his collection concentrates on Liberty ships. I know enough about his collection to know that he apparently has an image of PHILIP SCHUYLER. Mr. Hultgren has no e-mail or internet presence so send him an old-fashioned letter. He is quite elderly but at last report was still actively managing his collection. I understand he charges $10 for an 8x10 B&W copy.
