passenger list and ship name needed 1913

I need to find someone who knows the ship name and passenger list for a 1913 voyage from Bergen, Norway to NY. My relative Conrad Ole Hansen b- 11/1893 in Bergen, came here in 1913 and settled in Iowa. He married Edna Lizer in 1917. They had 3 children and lived in Iowa until WW2 when they moved to LongBeach, CA. He died 1973 in LongBeach, CA and is buried in Westminster Cemetery. I have a 1920 Iowa census showing his birth place, language, and his parents info all being from Bergen, Norway. It also shows he came here in 1913 through NY. Lisa in CA
