Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] Such as Figure 1 to Figure 4 As shown, the present invention includes a supply ship 101 and a supplied ship 113. A crane base 106 is installed on the deck of the supply ship 101. The crane can realize a larger operating range, facilitate the completion of cargo replenishment between ships, and save the supply ship 101' of deck area. A boom 107 is installed on the base 106, and the boom 107 is rotatably connected with the base 106 by a hinge, and the other end of the boom 107 is equipped with a crane head 201, such as figure 2 As shown, the first guide wheel 104 and the second guide wheel 109 are installed on the crane head 201 .

[0037] Such as figure 1 As shown, a measuring winch 108 is installed on one side of the boom 107, and a compensation winch 105 is installed on the other side, as image 3 As shown, the measuring winch 108 includes an encoder 301, a se...

Abstract

The invention discloses a ship crane heave compensation system, a compensation method and an operation method. The ship crane heave compensation system comprises a supply ship and a supplied ship, wherein a base is mounted on the supply ship; a suspension arm is mounted on the base; a measuring winch is mounted on one side of the suspension arm; a compensation winch is mounted on the other side of the suspension arm; a first guide wheel and a second guide wheel are mounted at the end part of the suspension arm; a first steel wire rope is connected between the first guide wheel and the compensation winch; the first steel wire rope penetrates through the first guide wheel; a lifting hook is arranged at the tail end of the first steel wire rope; a second steel wire rope is connected between the second guide wheel and the measuring winch; the second steel wire rope penetrates through the second guide wheel; and a measuring hook is connected to the tail end of the second steel wire rope. According to the ship crane heave compensation system, the compensation method and the operation method, an encoder is adopted to measure the relative heave motion speed and acceleration of the two ships, the compensation winch is adopted to perform active heave compensation motion on the cargo lifting hook, accurate and timely heave compensation motion can be guaranteed under severe sea conditions and under the condition that the two ships swing indefinitely, the construction cost is low, and the ship crane heave compensation system, the compensation method and the operation method are suitable for popularization.

Description

technical field [0001] The invention relates to a heave compensation system, a compensation method and an operation method, in particular to a heave compensation system, a compensation method and an operation method of a marine crane. Background technique [0002] With the continuous development of marine resources, marine cranes are an indispensable and important tool for replenishment, salvage and rescue at sea. When the ship crane is operating at sea, due to the influence of wind and waves and the hydrodynamic interference between the two ships, there will be more severe swaying motion than that of a single ship, which will affect the safety and efficiency of the operation. The existing marine crane with wave heave compensation can realize the cargo transportation between the ship and the fixed offshore platform (offshore platform) or fixed offshore platform under harsh sea conditions, and ensure efficient and safe cargo transfer The mission, however, does not apply to c...
