Affiliates of five companies are now building one of the largest single new natural-gas pipelines ever laid in the Gulf of Mexico. The High Island Offshore System (HIOS) will be the first subsea line to tap newly discovered gas reserves in the outer continental shelf in Texas waters. HIOS will lay 67 miles of 42-in., 26 miles of 36-in., and 110.5 miles of 30-in.-diameter pipe. The 42-in.- diameter pipe is the largest ever laid in the Gulf of Mexico. To complement this fact, the 42-in. line is being laid by one of the largest pipe-lay barges in the world -- Brown & Root's BAR 347. Certificated capacity of the system is 988 MMcfd less fuel used. This capacity is expandable to 2 billion cfd. Different stages in the pipeline's construction are detailed.
