摘要

If LNG tankers could travel underwater, they could transport natural gas from Arctic regions year-round. General Dynamics has designed just such a tanker - a 140,000-m/sup 3/ submarine with a methane-fired steam-propulsion system that uses recirculated exhaust gas injected with oxygen to sustain combustion. (Nuclear power would be cheaper but might not be practical if new regulations are imposed.) Developed from parametric variations in cargo capacity, hull material, and ballasting, the design identifies such ship characteristics as length, beam, depth, cargo-system arrangement, speed, and ship control. An economic analysis indicates the concept's competitiveness with both pipelines and icebreaking tankers.
