A catwalk apparatus for forming stands from individual tubulars comprises a frame having a top surface adapted to receive tubulars. The apparatus also includes a skate mechanism capable of pushing and pulling the tubulars once loaded on the apparatus. The apparatus is adapted to receive at least two tubulars in a coaxial arrangement. The apparatus includes a rotating means for oppositely rotating the tubulars along their longitudinal axes. The skate mechanism is used to advance the tubulars together during rotation so as to allow cooperatively threaded ends of the tubulars to engage thereby forming a stand. The skate mechanism is also used to urge the stand towards the drill rig for subsequent hoisting and orienting vertically. A method and system for forming tubulars is also provided.
