TLDR
In this article, a pull test system of a pipe-laying ship is described, where a detachable deflecting pulley device is used to replace a traditional fixed lifting lug and is provided with a universal traction connector applicable to tubes of different diameters through refit.Abstract:
The invention discloses a pull test system of a pipe-laying ship. The pull test system of the pipe-laying ship comprises a guide pulley, a tooling steel cable, a triangular plate, a traction winch cable, a universal tube connector, a tensioner, a traction winch and a pipe, wherein the triangular plate is connected to the traction winch through the traction winch cable, the universal tube connector is connected to the pipe penetreating the tensioner, the traction winch cable penetrates the universal tube connector, the guide pulley is fixedly connected to a fixed base, the tooling cable is wound through the guide pulley to be connected to the triangular plate and the universal tube connector respectively, and the universal tube connector comprises a hauling eye plate. The invention further discloses a pull test method of the pipe-laying ship. The pull test system of the pipe-laying ship uses a detachable deflecting pulley device to replace a traditional fixed lifting lug and is provided with a universal traction connector applicable to tubes of different diameters through refit, thereby greatly reducing the occupation space of the pull test system, improving the efficiency and solving the problem of the conflict of the guide pulley located in the middle side of the ship with other equipment.read more
