The invention provides a launching method of an ocean platform on a slipway by using a 38000t semi-submersible barge. The method comprises the steps that: a platform reaches a launching state; a lowersliding way is laid; pulling and moving equipment is installed; platform pulling lugs correspond to semi-submersible barge pulling lugs one to one; an upper sliding way is laid on the lower sliding way; the platform falls on the upper sliding way; a steel wire rope penetrates through; the platform is pulled and moved; preparation before diving separation is carried out; diving separation is carried out; semi-submersible barge ballast water drainage and berthing wharf dragging are carried out; and platform launching is ended. According to the method, a 35t pulling winch arranged on the semi-submersible barge pulls a platform on a shipway to the semi-submersible barge through a pulling slideway under the traction of a steel wire rope, the platform is separated after the semi-submersible barge dives, and launching of the platform on the shipway is completed. The number of handles of a 350t five-handle pulley winding steel wire rope is selected according to the weight of the platform. Theslideway pulling launching solves the problem that platforms and ships built on a shipway are difficult to launch, and the pulling slideway, the pulling winch and other devices can be repeatedly used.

    本发明提供了一种海洋平台在船台建造利用38000t半潜驳船下水方法,包含平台达到下水状态,铺设下滑道,安装拉移设备,平台拉耳与半潜驳船拉耳一一对应,下滑道上铺设上滑道,平台落在上滑道上,穿钢丝绳,平台拉移,下潜分离前准备,下潜分离,半潜驳船排压载水,拖回靠泊码头,平台下水结束。该方法由布置在半潜驳船上布置的35t拉移绞车通过钢丝绳牵引将船台上的平台通过拉移滑道拉移到半潜驳船上,半潜驳船下潜后平台分离,完成船台上平台下水。根据平台的重量选择350t 5柄滑轮缠绕钢丝绳的柄数。滑道拉移下水解决了船台上建造的平台和船舶下水困难,拉移滑道和拉移绞车等设备可以多次重复使用。
