An assembly process of a helideck of an offshore platform includes the steps of 1, building the helideck on a flat ground by means of inversion, transporting the helideck to a painting shop, and performing overall sand-blasting painting; 2, transporting the helideck to an offshore platform assembly site; 3, hooking two cranes rested on two sides of the helideck; 4, lifting the cranes to raise the helideck to a set height; 5, lowing a hook of the crane on one side slowly, and stopping forward moving when the helideck turns to a set angle; 6, lowering the hood until that the helideck is turned to 100 to 120 degrees; 7, interchanging a deck top and an oblique support until that the helideck is turned; 8, lifting the helideck to the offshore platform. Since the upper surface of the helideck is flat, the helideck is inverted and built; building efficiency is greatly improved, and operating is safer and better in quality.
