Pulling structures into water
A structure such as a pipeline bundle is pulled into or through shallow water, for example, when launching the structure, by applying a tensile pulling force to the structure through rigging that extends to the structure from a winch of a first vessel. The pulling force is at least partially reacted through a pennant line that extends from the first vessel to a second vessel and that hangs between the first and second vessels to engage the seabed soil frictionally. The vessels can also self-propel to contribute their thrust to the pulling force. The pennant line includes a clump weight such as a bundle of chains that can be repositioned easily for additional pulls by being lifted between the vessels before being lowered to the seabed at a new location.

A river vessel pushing connection locking device
This invention relates to the field of ship docking technology and discloses an inland waterway vessel push-connection and locking device, including a push-boat and a barge. A push-mounted frame is fixedly connected to the side wall of the push-boat, and a positioning groove is provided on the inner wall of the barge. The outer wall of the push-mounted frame is slidably connected to the inner wall of the positioning groove. A placement groove is provided on the inner wall of the barge. When the electric telescopic rod is activated, it retracts, causing the sliding plate and sliding disc to rise, thus raising the positioning rod. Through the support assembly, the arc-shaped support block contacts the positioning hole of the push-mounted frame. Through the insertion assembly, the positioning rod moves in multiple directions, so that multiple arc-shaped support blocks simultaneously contact the positioning hole of the push-mounted frame. Through the application of the above components, the positioning rod can be quickly and accurately inserted into the positioning hole, effectively preventing the positioning rod and positioning hole from being difficult to align due to the swaying of the push-boat and barge, thus making docking difficult. This reduces the difficulty for operators to repeatedly fine-tune the position of the push-boat and shortens the docking time between the push-boat and the barge.
