Describes the design and construction of an LNG (Liquefied natural gas) unloading terminal, the largest in the U.S. and second only to one in Japan, nearing completion at Cove Point, Md., on the Chesapeake Bay. Tankers will be unloading Algerian LNG at offshore berths from where it will be piped to shore, still as a liquid at -260 degrees F through a mile-long sunken-tube tunnel. This is the first such application of tunnel construction for carrying LNG. The original terminal design had provided for a conventional pile-supported trestle with pipeway and roadway from the offshore berths to the onshore storage and regasification plant. However, in view of the situation of the terminal in a relatively unspoiled, recreational area, and, particularly of the wetlands area with its value to the over-all local ecology, objections were raised by environmentalists resulting in the substitution of the tunnel for the more visible trestle.
