Abstract
The present invention is embodied in shipboard apparatus for heat-treating pieces of wood or wood products, such as logs, lumber wood chips or wood strands with steam or hot water to kill any plant pests present in the wood or wood products. The pieces are loaded into a hold of a ship. The ship is equipped with a heater or boiler for producing steam or hot water, and piping and associated equipment such as nozzles for introducing the steam or hot water into the hold. In some embodiments, the ship is also equipped with piping for recycling the spent steam or water back to the heater or boiler for producing the steam or hot water. As the steam or hot water is introduced into the hold, the wood pieces are contacted with the steam or hot water to raise the temperature of the pieces to a sufficient level for a sufficient period of time to kill any plant pests that might be present.
