ARCO Oil and Gas Co. recently installed a 20,000-ft submarine gas pipeline between seep containment structures in the Santa Barbara Channel and the Ellwood onshore facility. ARCO selected corrosion-resistant materials for the pipeline in view of an anticipated 9% to 11% carbon-dioxide content in the seep-gas stream. The major innovations were: Adapting a multiwall pipe material to standard installation procedures for submarine procedures for submarine pipelines. Featuring a fiberglass reinforced thermoset inner pipe which does not exhibit structural shape change under external pressure and allows the use of the cement as a second defense corrosion-control system. Development of a joining system to economically and efficiently connect multiwall pipe.
