Unforgettable 100 hours – Hanas HangYin Silver Line Yellow River running through work silhouettes
A HangYin silver engineering project as Ningxia Hanas 5 million tons of liquefied natural gas project integration base. It is a key project of the national natural gas and planning of Ningxia in 13th Five-Year plan. After the project was put into operation, the short board was filled to fill the Mongolia Ning natural gas transmission project. It is of great significance to realize the diversification of gas supply in Ningxia. It is an important foundation for increasing the proportion of natural gas consumption and promoting industrial transformation iteration. It will promote the development of related industries such as machinery, electric power, traffic and building materials along the line. The forward will bear Hanas Ningxia 5 million tons of liquefied natural gas supply base integration task. For energy conservation and emission reduction, “gasification Ningxia” to provide resource protection, economic and social benefits of great significance. At the same time, through the construction of HangYin silver, it will further improve the inter provincial natural gas pipeline network construction. We will implement the overall deployment of national oil and gas reform, and build a modern natural gas industry system that is well-structured, safe and reliable, and coordinated between supply and demand. It has a profound impact on the formation of inter regional interconnection.
The Yellow River directional drilling is the throat project of Hangzhou silver line project. It is the most important crossing point located in the Helan section of the mainstream of the Yellow River. East and west coast are belong to Ningxia Pingluo County and Helan County, crossing the length of 2700 meters, crossing the main diameter Φ711 Mm × 15.9 mm, the depth of 36 meters below the surface of the water, mainly through the formation of mud, sand.
In order to ensure the smooth implementation of the project through the Yellow River, Hanas project management company that the pipeline company with the construction unit to develop 100 hours security work plan, combat readiness. 100 hours continuous duty, keep the scene, protect the construction, protect the logistics. May 12, 2017 02:18 to 13 00:38, which lasted 22 hours and 20 minutes. The average speed of 125 meters / hour which the project successfully completed the drag back task and successfully across the Yellow River. Record of the largest diameter, the longest one-way, the fastest speed across the Yellow River! Now follow their footsteps and look back at the memorable 100 hours:
May 10 – 11, posted a bulletin, known to the surrounding masses
From May 10 to May 11, set warning signs across the perimeter to ensure the safety of pedestrians and vehicles in the past
May 10-13, day and night on duty, to ensure that prefabricated pipelines through regional personnel safety
May 11, to complete the construction of sending trench ditch, water, prefabricated pipe into the ditch, ready to go back to drag
May 12 at 01:30, to complete the preparation for the back-drag equipment installation
May 12 02:18, back to drag start
May 12 at 02:38, the pipe head is buried
May 12 09:28, tail pipe through the cement road
At 14:45 on May 12, along the pipeline back to check the situation
At 18:30 on May 12, the pipeline successfully dragged down 1748 meters
At 19:50 on May 12, check the resumption of work on all roads to ensure the safety of past pedestrians
At 23:45 on May 12, the pipeline successfully dragged back 2478 meters, close to the end of tube into the soil
At 00:38 on May 13, the pipe head was successfully unearthed and the drag was completed smoothly
On May 13 at 09:00, Ren Fenglan, vice president, condolences to construction, supervision, anti-corrosion and testing units on behalf of the Group,
09:30 on May 13, a big photo sharing the joy of victory
80 day and night fighting, 100 hours full protection, Hanas to dare to fight the tough quality, bravery, unity and cooperation of the Hanas spirit, the Yellow River across the smooth completion of the traversal for the entire trial put into operation on a solid basis. At present, the project Ningxia section has been completed more than half. Mongolia section has launched land acquisition work, sweeping line started. The project will be put into trial operation by the end of 2017!
