浮标辅助定位导航系统是一种新技术。我公司今年四月至六月与埃索石油公司合作,用此系统为埃索石油公司完成了数千公里的三维地震工作,结果令双方十分满意。此项工作原定103天完成,实际只用了63天,提前了40天,节约了大笔开支。导航精度方面,此系统的综合误差(浮标自身误差与无线电定位设备的误差)不大于4米。施工区域的水深约100米,施工期间遭遇两次七级以上大风,波浪高达5米以上,但自始至终连续开机,整个系统都保持正常状态,并取得了较高的精度。因此,浮标辅助定位导航系统很有推广使用的价值。
Buoy assisted positioning navigation system is a new technology. Our company cooperated with Esso Petroleum Corporation from April to June this year and completed the three-dimensional seismic work for Esso Oil Company for thousands of kilometers. As a result, both parties are very satisfied. This work was originally completed 103 days, the actual only 63 days, 40 days in advance, saving a lot of expenses. Navigation accuracy, the system’s overall error (buoy own error and radio positioning equipment error) is not more than 4 meters. The water depth in the construction area is about 100 meters. During the construction period, two gales of more than seven degrees are encountered and the wave height is more than 5 meters. However, the system is continuously powered on from start to finish, and the entire system maintains normal condition with high precision. Therefore, buoy assisted positioning navigation system is very useful to promote the use of value.
