Heat barrier components and improved thermal insulation techniques are provided for an external tank insulation system of ships carrying liquefied natural gas, propane, ammonia, etc. Reduction of liquid boil-off rate or initial cost of insulation through the reduction of radiant heat leak is accomplished by a composite insulation system including a high reflectance component material on the external surface of insulation and/or interior surface of the ship facing the tank. Further, refrigeration in tank boil-off is used to cool a radiation shield located between the tank insulation and surrounding enclosure, and to cool the skit support.
