“雪龙2”号极地考察船月池系统的设计与应用

Design and application of moonpool system in polar icebreaker Xuelong 2

  • 摘要:
    目的 在极地密集浮冰区极地考察船通过舷侧投放和回收科考探测及采样设备的作业模式受限,因此,为顺利获取极地密集浮冰区内数据和样品,需在“雪龙2”号极地考察船舯部设计月池。
    方法 结合我国多年极地科学考察的经验,充分考虑极地冰区作业的特点,合理设计可在舷侧与月池作业切换的动线方案,使用创新的水压密月池底盖、特殊的轨道对接方案、低温环境下活动关节除冰等针对性设计,并经过南极考察现场作业的检验。
    结果 结果表明,该设计方案可有效开展极地密集浮冰区内科考调查设备的投放和回收作业。
    结论 所设计的月池系统能够较好地适用于我国极地考察船的实际需求,形成了与“雪龙2”号船破冰能力相匹配的密集浮冰区调查取样能力。

     

    Abstract:
    Objective In the polar regions, the operation mode of launching and recovering detection and sampling devices for scientific research by shipside is limited due to dense ice floes around the ship. To achieve the smooth acquisition of data records and samples in densely packed ice floe regions, a square-shaped moonpool system was designed in the midships of the Xuelong 2 icebreaker.
    Methods Benefiting from the accumulated experience of decades of polar surveys, and taking ice zone operation characteristics into full account, the design option of a reasonable switching process between shipside and moonpool operation was put forward. Specifically, innovative techniques such as the watertight bottom cover of the moonpool, special track docking plan and deicing of movable joints in low temperature environments were implemented.
    Result Field tests in the Antarctic area have demonstrated that the proposed scheme can effectively deal with the problem of launching and recovering scientific survey devices in densely packed ice floe regions.
    Conclusions The proposed moonpool scheme meets the actual needs of Chinese polar expeditions by increasing the sampling capability of Xuelong 2 in densely packed ice floe regions and matching the icebreaking capacity of the ship.
