"Offshore oil 720" operating in Arctic waters.
Original title: Geophysical ships successfully completed seismic exploration in Arctic waters for the first time, China jobs
In the Green online news (China Youth reported ? in the Green online reporter Cui Li) August 9, China Sea oil its in the sea oilfield service Corporation (Xia said in the Sea oil clothing) most advanced of 12 cable geophysical ship "marine oil 720" lasted 100 days, successfully completed Arctic Barents Sea two a block job, fill has China on Arctic waters implementation three dimensional earthquake exploration of blank, while created the ship three dimensional earthquake collection job per month 1820.58 square km of record, this is China three dimensional earthquake collection per month highest records.
According to reports, the operating area in the Northern Barents Sea in the Arctic Circle, more than 75 ° latitude, deep inside the Arctic Circle 900duoqianmi hinterland, the insurance industry found latitude 70 ° above as a high risk area. This was China's first in ultra high latitudes and frigid area of three-dimensional seismic exploration acquisition, "offshore oil 720" is China's Ministry of transport has recorded the first aircraft arrived at the Chinese boats in the area, currently only a handful of geophysical companies have in their ability to work in the area.
Area of the complex of the Northern Barents Sea, sea water for glacier water, even in the heat of July, sea water is still hovering around zero degrees Celsius. "Offshore oil 720" fleet manager Chen Zhiwei said, "the job without any experience in the Arctic, and low temperature operation, journeyed long and when the window is short on personnel and exploration equipment, a new and unprecedented challenges."
In the Arctic seas, due to the cold weather, only rare 4-5 months of the year operating window. In order to quality for a limited time to complete homework, "offshore oil 720" fleet all weather operation modes, overcome journeyed to the physical and mental effects of the crew; they continue to optimize the ship's turning radius and turning, using 24 hour seamless maintenance and replacement underwater equipment, improve work efficiency and quality, geophysical seismic acquisition, China July refresh monthly highest on record.
"Marine oil 720" is Asia first ship most new deepwater three dimensional earthquake geophysical ship, is China independent built of first ship large deepwater geophysical ship, is China design and built of first ship meet PSPC standard (protection coating performance standard) of marine engineering ship, is China first ship by wood electric advance system drive, and can sailing Yu global I class unlimited airlines district of 12 cable double source large geophysical ship, for International Geophysical ship mainstream ship type and technology representative.

中国物探船完成首次北极海域地震勘探作业|物探船|北极海域_新闻资讯
“海洋石油720”在北极海域作业。
原标题：中国物探船圆满完成首次北极海域地震勘探作业
中青在线讯（中国青年报·中青在线记者 崔丽） 8月9日，中国海油旗下中海油田服务股份有限公司（下称中海油服）最先进的12缆物探船“海洋石油720”历时100天，圆满完成北极巴伦支海两个区块作业，填补了中国对北极海域实施三维地震勘探的空白，同时创造该船三维地震采集作业月产1820.58平方千米的新纪录，这是中国三维地震采集月产最高纪录。
据介绍，此次作业工区位于北极圈内的巴伦支海北部，纬度达75°以上，深入北极圈内900多千米腹地，保险业界认定纬度在70°以上即为高风险作业区。这是中国首次尝试在超高纬度和极寒海域进行三维地震勘探采集作业，“海洋石油720”是中国交通运输部有记载以来首艘抵达该海域的中国船只，目前全球仅有少数几家地球物理公司具备在该海域作业的能力。
巴伦支海北部海域工区状况复杂，海水多为冰川水，即便是在炎热的7月，海水仍在零摄氏度左右徘徊。“海洋石油720”船队经理陈志玮称，“此次北极作业无任何经验可循，低温作业、极昼持续长以及作业时窗短是对人员和勘探设备的一次前所未有的考验”。
在北极海域作业，由于气候寒冷，一年仅有难得的4-5个月作业时窗。为了能在有限的工期内高质量完成作业，“海洋石油720”船队采用全天候作业模式，克服极昼对船员身心带来的影响；他们不断优化船舶转向半径和转向时间，采用24小时无缝隙维修更换水下设备，提高了作业效率和质量，7月刷新了中国物探三维地震采集月产最高纪录。
“海洋石油720”是亚洲首艘最新一代深水三维地震物探船，是中国自主建造的第一艘大型深水物探船，是中国设计和建造的第一艘满足PSPC标准（防护涂层性能标准）的海洋工程船，也是中国第一艘由柴电推进系统驱动、可航行于全球I类无限航区的12缆双震源大型物探船，为国际物探船主流船型和技术代表。
