用于钻井船的移运系统及其吊车和月池台车
摘要：
本发明提供了一种用于钻井船的移运系统及其吊车和月池台车。所述吊车用于吊运防喷器或采油树，所述吊车包括主梁结构和两个主绞车，其中，在主梁结构上沿着主梁结构的长度方向设置有轨道，两个主绞车能够沿着所述轨道移动以调节两个主绞车之间沿主梁结构的长度方向的距离。通过本发明的各实施例，可以使得移运系统能够为防喷器和采油树共用，减小了对船体的占用尺寸，减轻了甲板负荷。
摘要（英）：

The invention provides a transport system, a crane and a moon pool trolley for a drilling ship. The crane is used for hoisting a blowout preventer or a Christmas tree, and the crane comprises a main beam structure and two main winches, wherein a rail is arranged on the main beam structure in the length direction of the main beam structure; and the two main winches can move along the rail to adjustthe distance between the two main winches in the length direction of the main beam structure. Through the arrangement of the transport system, the crane and the moon pool trolley for the drilling ship, the transport system can be shared by the blowout preventer and the Christmas tree, and thus the space occupied on the ship is reduced, and the deck load is reduced.
