Abstract
A marine gas storage and transport system formed of small diameter steel pipe, which is coiled and stacked in a specific manner. The system is suitable for use on top of a barge or inside the holds of a ship, when contained within a secondary containment system. The specific manner in which the pipe is coiled is such that about 97% of the total length of pipe coiled may be described by constant curvature or pure circles. Additionally these circles lie directly on top of one another about 94% of the time and vertical stacking stresses are minimized. Only about 6% of the pipe is involved in crossover geometry. This method, of about 97% circular coiling, combined with about 3% transitional coiling results in a continuous length of pipe that nests easily, provides greatly reduced contact stresses and is very economic to construct due to its ease of nesting and it's long lengths of constant curvature. Descriptions of the marine transport system or the coil containment system are not included since they are described in related patents.
