The author:(作者)delvpublished in(发表于) 2014/1/2 8:46:33 Programme of rescue the Russian ship Snow Dragon， determined that 52 passengers will travel by air transfers
January 2, according to the State Oceanic Administration Web site message, carrying 74 people of Russia, "Shao Kaliski, academician of" passenger ship trapped in Antarctica has been 7 days. At present, the "Snow Dragon" preliminary rescue package--will be spent on the ship "Snow Dragon" on board "Ka-32" helicopter rescue. Apart from the 22 crew members remain in the plan, "Shao Kaliski academicians", remaining 52 passengers will take a helicopter to the "Snow Dragon" vessel.
January 1, Beijing time, Australia "Aurora" ships arrived in the Russian ship trapped near the sea, from the "Snow Dragon" boat only about 4 nautical miles, will complement the "Snow Dragon" vessel to complete the rescue.
Since the beginning of December 25, continuous strong southeast winds will continue to blow to the Russian ship open pack ice in the waters of trapped water. Affected by this, the ice floes in the sea is also constantly squeezing, tightening, ice, sea ice density continues to increase, and forms a ridge, "Shao Kaliski academicians" ice rescue has been difficult to achieve.
On December 31, Russia stranded vessel "Shao Kaliski, academician of" Captain formally to request a letter of "Snow Dragon" ship helicopter rescue, 30th Antarctic scientific expedition in China set up a working group on sea ice. Working Group will mainly carry out rescue equipment and material planning, liaison with the Russian side, ice reconnaissance, selection of helicopter landing sites, set the waiting area and the boarding area, boarding, inventory of foreign personnel working in the command. At the same time, the "Snow Dragon" the medical team on board working group has also been active with logistic and life.
Provisional party for the 30th Antarctic expedition by China and Russia, "Shao Kaliski academicians" number, the Australia Centre for search and rescue "and" Aurora "Quartet deliberations to finalize the" Snow Dragon "vessel" Ka-32 "helicopters to transfer the trapped crew of the Russian ships.
In accordance with the agreed rescue plan, the "Snow Dragon" will send the ship "Ka-32" helicopter "Shao Kaliski, academician of" safe ice trapped near the passenger ship to rescue personnel.
Apart from the 22 crew members remain in the plan, "Shao Kaliski academicians", remaining 52 passengers will take a helicopter to the "Snow Dragon" vessel. For the "Snow Dragon" vessel with the "Aurora" common retreated to the Clearwater area, trapped people by boat from the "Snow Dragon" ship to "Aurora" aboard the ship.
Take off time, the expedition team provisional Party Secretary, team leader Liu shunlin said, the weather is still not suitable for helicopters to take off. In order to ensure that personnel and flight safety, helicopters will choose a good weather for flying, in addition, the "Snow Dragon" also will be sent in advance to the boat trapped Russian ships near the ice surface for landing site selection, prospecting and laying of Kosovska Mitrovica and other works.
According to Liang Gaosheng pilot introduction, minimum landing conditions required for helicopters: wind and wind speed not exceeding 15 metres per second switch, no more than 10 meters per second crosswind, not more than 8 meters per second wind, visibility is not less than 2 kilometres, cloud base height of not less than 150 metres, landing site area of no less than 22 m × m.
According to the "Snow Dragon" marine weather forecast of the security unit, the cyclone-affected, the current "Snow Dragon" boat sea wind is relatively large, up to grade 7, and visibility was poor.
It is reported that "Ka-32" helicopter "Snow Dragon" used in the ship's engineering machines, usually used to hang and shipments. Except for pilots and aircrew, a total of 12 seats.
During waiting for better weather to prevent trapped by sea ice, the "Snow Dragon" kept the ship maneuvering, expanding the work surface, and looking for a safe stop.
"At present, we are where sea ice density is too high, ice must be to prevent blocked by ice. "" Snow Dragon "ship's captain Wang Jianzhong said," Snow Dragon "ship is driven by inertia speed, coupled with its own gravity, ice breaking. When faced with thick pack ice, icebreaker to go back about 3 hull in order to speed up, thereby creating the right kind of collision force, breaking the ice, "now we can only refund up to two hulls, plus the ice is very thick, so ice is very hard. ”
Ship is a certain risk in ice, especially the "Snow Dragon" ship in ice density reached to 10, this was a severe test for the driver.
"Snow Dragon" boat marine rail of elders and Wu Jian, sailing on the ice to pay special attention to two points, the first is to prevent the rudder was jammed by ice, is to prevent the propeller into ice in the second. "Once the rudder broke, meaning ' Snow Dragon ' boat lost directional control. Propeller snaps into ice, can also be easily inside the shaft is damaged, causing the propeller does not work, the ship lost power, the very serious consequences. "And Wu Jian said.
(Edit: SN091)January 02, 2014 China News Network(雪龙号救援俄船方案确定 52名乘客将乘机转移|雪龙|直升机|乘客_新闻资讯
中新网1月2日电 据国家海洋局网站消息，载有74人的俄罗斯“绍卡利斯基院士”号客船在南极被困已7天。目前，“雪龙”船初步确定了救援方案——将动用“雪龙”船上的“ka-32”直升机进行救援。除计划中的22名船员继续留守之外，“绍卡利斯基院士”号其余52名乘客将搭乘直升机前往“雪龙”船。
北京时间1月1日15时30分，澳大利亚“极光”号船抵达俄船被困附近海域，距离“雪龙”船仅4海里左右，将配合“雪龙”船共同完成此次救援。
自12月25日开始，连续的强东南风将开阔水域的浮冰不断吹向俄船被困海域。受此影响，该海域原本就存在的浮冰也在不断地挤压、收紧，冰情加剧，海冰密度不断加大，并形成冰脊，对“绍卡利斯基院士”号破冰救援已经难以实现。
12月31日，俄罗斯被困船只“绍卡利斯基院士”号船长正式来函请求“雪龙”船提供直升机救援，中国第30次南极科学考察队成立了海冰工作组。工作组将主要开展救援设备和物资准备、与俄方联络、勘察冰面、选择直升机降落场地、设置等待区和登机区、指挥登机、清点外方人员等工作。同时，“雪龙”船上的医疗小组和生活小组等也积极做好后勤保障工作。
经中国第30次南极考察队临时党委与俄罗斯“绍卡利斯基院士”号、澳大利亚搜救中心及“极光”号四方商议，最终确定用“雪龙”船的“ka-32”直升机对被困俄船上的人员进行转移。
根据商定的救援计划，“雪龙”船将派出“ka-32”直升机前往“绍卡利斯基院士”号客船附近安全冰面对受困人员进行救助。
除计划中的22名船员继续留守之外，“绍卡利斯基院士”号其余52名乘客将搭乘直升机前往“雪龙”船。之后，“雪龙”船与“极光”号共同退至清水区，受困人员再通过小艇从“雪龙”船转至“极光”号船上。
至于起飞的时间，考察队临时党委书记、领队刘顺林表示，目前天气仍不适合直升机起飞。为确保人员和飞行安全，直升机将选择一个良好的天气进行飞行，此外，“雪龙”船还将提前派人前往被困俄船附近冰面进行降落场地的选择、勘与察铺设等工作。
据飞行员梁高升介绍，直升机最低起降条件要求为：开关车逆风风速不超过每秒15米，侧风不超过每秒10米，顺风不超过每秒8米，能见度不小于2公里，云底高不低于150米，降落场地面积不低于22米×22米。
据“雪龙”船气象保障组的预报，受大气旋影响，目前“雪龙”船所在海域风力比较大，达7级，且能见度较差。
据悉，“ka-32”直升机是“雪龙”船上的工程用机，平时主要用来吊挂和装运物资。内部除驾驶员及机组人员以外，共有12个座位。
在等待天气转好期间，为防止被海冰困住，“雪龙”船始终保持机动，不断扩大作业面，并寻找安全停靠点。
“目前，我们所在的海域海冰密度太高了，必须要进行破冰以防止被冰卡住。”“雪龙”船船长王建忠称，“雪龙”船主要靠惯性速度，加上自身的重力，将冰破开。在面对较厚的浮冰时，破冰船一般要后退大概3个船身才能将速度提上去，从而产生合适的冲撞力，进而进行破冰，“现在我们最多也就只能退两个船身，加上冰又非常厚，所以破冰非常艰难。”
船舶在冰区航行是有一定危险性的，尤其是“雪龙”船目前身处的冰区密集度达十成，这对驾驶员来说也是一个严峻的考验。
“雪龙”船轮机长老轨吴健指，在冰区航行有两点要格外注意，第一是防止舵被冰卡住，二是防止螺旋桨里卡入冰块。“一旦舵坏了，就意味着‘雪龙’船失去了方向控制。螺旋桨内卡入冰块，也容易把里面的轴损坏，造成螺旋桨无法工作，船就失去了动力，后果非常严重。”吴健说。
