The Connecticut ne ticu necticut Build Build ild d Awards wards ward wards ad 2008 Winner: Large New Construction Project Yankee Gas Liquid Natural Gas Facility O&G Industries, Inc. Torrington, Conn. O&G Builds a Quadrant industry, teamed with O&G Industries, Inc. of Torrington to bid on this $108 million design/build job. “CB&I contacted us to take care of all the concrete work, the site and civil work and all of the ancillary buildings that were constructed at the facility,” says Jason W. Travelstead, assistant vice president of operations. That portion of the project was worth $19.4 million. The team won the project in 2004. The site had previously been used as a coal gasification plant, and another contractor came in to do the site remediation work before CB&I and O&G Industries took over. As CB&I began to build its portion of the tank, O&G began work on the site and civil work for the project, which included drainage, site sewer, and sanitary. They also built roads to the new tank site. Construction of the tank required careful coordination between the partners. Measuring 130 feet high and 158 feet in diameter, it was made of a steel liner encased in post-tensioned concrete. “CB&I first created an inner tank made of nickel steel that actually holds the LNG,” says Travelstead. Outside of that, CB&I built a steel tank, which served as one side of the concrete containment shell. “They would build that tank 50 feet vertically ahead of us, taking steel plate and welding it together. Then they used steel whalers to give the tank its shape,” Travelstead explains. O&G poured against that second steel tank, using a one-sided form with climbing scaffolding. “That one-sided form presents its own set of issues. It had to be Yankee Gas’ new Liquified Natural Gas (LNG) facility in Waterbury is the first of its kind in North America, with a tank capable of holding 14.6 million gallons of liquefied natural gas. LNG is natural gas that is imported to the U.S. by tanker ship, coming into the New England area via a port in Everett, Mass., and then traveling to the Waterbury facility via interstate pipelines or tanker trucks. The new storage facility allows Yankee Gas to buy LNG in the summer when demand and prices are lower and store it for peak winter days.
