The invention discloses an offshore transfer trestle with active and passive wave compensation functions and a working method. The trestle comprises a trestle system, a landing device, a measuring system, a trestle wave compensation control system and a landing device wave compensation control system. The landing base is adsorbed to the lap joint area on the deck of the target ship through the electromagnetic chuck, so that the position of the center of the spherical hinge can be kept unchanged when the landing device lands on the lap joint area on the deck of the target ship only by controlling the landing device to actively compensate the interference of the six-degree-of-freedom motion of the target ship on the right end position of the trestle bridge body; and the trestle can passively rotate, stretch and pitch under the interference of the six-degree-of-freedom oscillation movement of the mother ship, the oscillation movement of the mother ship is compensated, and the control is simple. The freeboard difference between a mother ship and a target ship can be offset to a certain degree, interference of six-degree-of-freedom motion of the target ship on the position, connected to the front end of a trestle, of a landing device supporting table is compensated, power needed by the landing device is reduced, and energy consumption is reduced.

    本发明公开了一种具有主被动波浪补偿功能的海上换乘栈桥及工作方法,所述栈桥包括栈桥系统、着陆装置、测量系统、栈桥波浪补偿控制系统和着陆装置波浪补偿控制系统。本发明的着陆基座通过电磁吸盘吸附于目标船甲板上的搭接区域,因此,只需要控制着陆装置主动补偿目标船六自由度运动对栈桥桥体右端位置的干扰,就可保持着陆装置着陆于目标船甲板上搭接区域时球铰球心所在的位置不变,而栈桥受母船六自由度摇荡运动干扰可被动地进行回转、伸缩和俯仰运动,补偿母船这些摇荡运动,控制简单。本发明可一定程度抵消母船与目标船的干舷差,补偿目标船六自由度运动对着陆装置支撑台上链接于栈桥前端位置的干扰,降低了着陆装置所需的动力,降低了能耗。
