To optimize the cost-effectiveness of LNG transport, Moss-Rosenberg examined several options, including reducing boiloff by using better tank insulation, improving the shape of the ship's hull, and raising the efficiency of the propulsion machinery. Steam-turbine plants with reheat, combined with a low (0.11%/day) boiloff rate, represent a significant improvement over today's standard propulsion equipment. If fuel rates are considered, however, the large-bore diesel engine proves superior. A boiloff-reliquefaction plant driven by main-engine power would permit the use of this diesel prime mover. The most economic ship speed, according to Moss-Rosenberg, is 17-18 knots; the optimal speed increases slightly for longer roundtrip distances and for boiloff-burning ships not equipped for reliquefaction
