The invention relates to the technical field of ocean engineering, and discloses medium-deep water suspended subsea pipeline semi-flexible dynamic positioning throwing and filling equipment which comprises a semi-flexible guide structure, a storage barrel used for storing the semi-flexible guide structure and a positioning traction device connected with the end of the semi-flexible guide structure. The semi-flexible guide structure comprises guide cylinders, lock holes are formed in the upper portions of the guide cylinders in the circumferential direction and connected with lock chains, the lock chains comprise the first type of lock chains and the second type of lock chains, the first type of lock chains are welded to the corresponding lock holes in the guide cylinders, and the second type of lock chains sequentially penetrate through the corresponding lock holes in all the guide cylinders. The bottom ends of the chains are fixedly connected with the positioning traction device, and the top ends of the second-type chains are connected with the hydraulic capstan. The semi-flexible guide structure and the positioning traction device are arranged, the semi-flexible guide structure is not affected by the outside in the process of extending to a slinging site, the throwing site is accurately positioned under the traction effect of the positioning traction device, the operation depth is increased, and the operation range is widened.
本发明涉及海洋工程技术领域,公开了一种中深水悬空海管半柔性动力定位抛填装备,包括半柔性导向结构,用于收纳半柔性导向结构的收纳筒以及与半柔性导向结构端部连接的定位牵引装置;半柔性导向结构包括导向筒,导向筒上部周向设置锁孔,锁孔与锁链连接,锁链包括第一类锁链和第二类锁链,第一类锁链与导向筒上对应的锁孔焊接,第二类锁链依次穿过所有导向筒上对应的锁孔;锁链的底端与定位牵引装置固定连接,第二类锁链的顶端与液压绞盘连接。本发明通过设置半柔性导向结构以及定位牵引装置,半柔性导向结构在伸长至抛砂地点的过程中不受外部影响,在定位牵引装置的牵引作用下精准定位投放地点,提高了作业深度和作业范围。
