China's State Administration of Work Safety and Ministry of Public Security have released results of their investigations into the July 16 Dalian explosion. The report said that "workers from a third party service provider, employed by a oil cargo owner, continued to inject strongly oxidising desulfurizer into the pipeline after the 300,000-ton tanker had finished unloading its oil.
Following the explosion at Dalian, Chinese authorities have imposed temporary navigation control at Xingang area and restricted port operations at three of its oil berths.
The restrictions have all been lifted, except for the Port's No. 0 oil berth, which has a berthing capacity of 300,000 dwt.
The No. 0 oil berth is expected to resume operations in the near future.
