The invention relates to the technical field of offshore anchoring systems, and discloses a multi-cylinder combined type suction anchor device and a construction method thereof. The multi-cylinder combined type suction anchor device comprises an auxiliary mechanism and a central suction anchor, the auxiliary mechanism comprises a connecting frame and auxiliary suction anchors fixed to the connecting frame in the circumferential direction of the connecting frame in an array mode, the central suction anchor is arranged in the middle of the connecting frame in a penetrating mode, and the central suction anchor comprises a central anchor cylinder and a ballast tank detachably installed on the central anchor cylinder; during anchor sinking, a whole formed by the auxiliary suction anchor and the connecting frame is vertically placed into water, water pumping and anchor sinking are conducted, the connecting frame is leveled, then the central suction anchor is placed, water pumping and anchor sinking are conducted, the suction force of the suction anchor device is increased and evenly distributed through the gravity of the ballast tank and the auxiliary mechanism, and the uplift bearing capacity and the anti-overturning capacity are improved; the system can better adapt to a severe deep sea environment, and the stability of an ocean development system is improved. The invention further provides a construction method of the multi-cylinder combined type suction anchor device.

    本申请涉及海上锚泊系统的技术领域,公开了一种多筒复合式吸力锚装置及其施工方法。提供了一种多筒复合式吸力锚装置,包括辅助机构和中央吸力锚,辅助机构包括连接架和沿连接架周向阵列固定于连接架上的辅助吸力锚,中央吸力锚穿设于连接架的中部,中央吸力锚包括中央锚筒和可拆卸安装于中央锚筒上的压载舱,沉锚时,先将辅助吸力锚与连接架构成的整体垂直放入水中,进行抽水沉锚并将连接架调平,然后再放入中央吸力锚并抽水沉锚,通过压载舱的重力和辅助机构增大并均匀分布了吸力锚装置的吸力,提升了抗拔承载力和抗倾覆能力,能更好地适应深海恶劣的环境,提高海洋开发系统的稳定性。还提供了一种多筒复合式吸力锚装置的施工方法。
