Abstract
A pipeline segment, used for the manufacture of a thin-walled underwater pipeline. Terminal pipe sectionsare at either end of main pipe section. Terminal pipe sectionsare thick-walled or otherwise resistant to collapse due to external pressure. A pressure isolation devicemaintains an internal pressure in main pipe sectionabove a shut off pressure. A pressure compensation systemcan protect main pipe sectionfrom collapse due to external pressure. Pipeline segmentscan be manufactured by connecting and winding stalksonto storage deviceforming main pipe section. Terminal pipe sectioncan be connected to the lead end of main pipe section, and main pipe sectioncan be unwound from storage devicewhile towing.
