Cleanup, surveillance after blast at port; affected areas fenced off
DALIAN - Workers rushed to contain an oil spill covering up to 50 square kilometers from seeping further into the Yellow Sea on Sunday, two days after an explosion at an oil storage port in Dalian, Liaoning province.
An oil pipeline exploded at 6 pm on Friday near Dalian's Xingang Harbor, triggering another blast at a smaller pipe nearby, Xinhua News Agency reported.
Both pipelines, owned by China National Petroleum Corp (CNPC), caught fire. Firefighters put out the blaze at the larger pipeline at around midnight. But at least five subsequent explosions fueled the fire at the smaller pipeline.
More than 2,000 firefighters fought the blaze and most of the fire was put out on Saturday morning, 15 hours after the initial explosion, Xinhua reported.
The local fire department was still cooling down affected oil tanks on Sunday to prevent any further risk of fire.
No deaths were reported in the fires.
The first blast occurred on Friday evening when a Liberian oil tanker was offloading oil, Chen Zhigang, an officer with the frontier station in Xingang Harbor, told China Daily.
An inspection team was formed on Sunday morning to investigate the blast but the cause of the accident has not yet been determined, said Sun Benqiang, deputy chief of the municipal work safety bureau.
After the fires were extinguished, workers began using oil skimmers and dispersants to contain the oil slick from spreading beyond the port into the Yellow Sea.
By Sunday evening, about 7,000 meters of floating booms had been set up and at least 20 oil skimmers were working to clean the spill, the Liaoning provincial maritime safety bureau said.
The affected region is about 100 sq km offshore, bureau officials said.
Eleven square kilometers of the ocean in the area are "relatively polluted", Wu Guogong, deputy director of Dalian's environmental protection bureau, told China Daily.
CNPC vowed on Sunday to "do its best" to reduce the impact of the explosion. Oil has stopped leaking into the sea as a valve has been closed, it said.
Oil that spilled into the sea has been fenced off and contained, CNPC said.
More than 20 air surveillance points and 10 offshore surveillance points are also monitoring the situation, Wu said.
