Tulsa-based Sheehan Pipe Line Construction Co. filed for chapter 11 protection on Friday in U.S. Bankruptcy Court for the Northern District of Oklahoma, the Tulsa World reported yesterday. Founded in 1903, the 113-year-old pipeline construction company's functions have expanded to include hydrostatic testing, valve changing and pipeline rehabilitation, but the company's focus is still primarily on laying infrastructure. The company's chapter 11 filing lists both estimated assets and liabilities as being somewhere in the $50 to $100 million range. The company's estimated number of creditors are listed as in the range of 200 to 999.
