本发明公开了一种适应钻井船的浮式钻井水下设备布置系统及作业方法,其中布置系统包括LMRP、BOP、采油树、BOP移运小车、采油树移运小车、BOP葫芦吊和采油树葫芦吊,LMRP储存在主甲板上,BOP储存在月池甲板上,BOP移运小车包括BOP移运小车车体、液压马达顶升装置和升降锁紧装置,所述液压马达顶升装置和所述升降锁紧装置分别与所述BOP移运小车车体固定连接。本发明可实现BOP组在BOP移运小车内的升降和锁紧,能充分利用月池区域上部受限空间;采用小型的BOP葫芦吊和采油树葫芦吊代替门型吊车,节约占用空间,降低设备成本;将LMRP和BOP分别储存在不同的甲板上,减少对整体空间的占用要求。

    The invention discloses a floating drilling underwater equipment placing system suitable for a drilling ship and an operation method. The floating drilling underwater equipment placing system suitablefor the drilling ship comprises an LMRP, a BOP, a Christmas tree, a BOP mobile trolley, a Christmas tree moving trolley, a BOP chain block and a Christmas tree chain block, wherein the LMRP is storedon a main deck; the BOP is stored on a moonpool deck; the BOP mobile trolley comprises a BOP mobile trolley body, a hydraulic motor jacking device and a lifting locking device; and the hydraulic motor jacking device and the lifting locking device are correspondingly and fixedly connected with the BOP mobile trolley body. According to the floating drilling underwater equipment placing system suitable for the drilling ship and the operation method, the lifting and locking of a BOP group in the BOP moving trolley can be realized; the upper limited space of a moonpool area can be sufficiently utilized; by using the small-sized BOP chain block and the Christmas tree chain block to replace a gantry crane, the floor space is saved, and the equipment cost is reduced; and as the LMRP and the BOP are correspondingly stored on the different decks, the occupation requirements on the integral space are reduced.
