Abstract: A modular heating section for removing or preventing the formation of ice on the walls of navigation locks, loading docks, ferry slips, or the like. Ice formation on the walls of navigation locks is compressed by successive vessels to the extent that larger vessels are unable to enter the locks. To avoid this happening, ice is chipped from the walls of the locks, which is time-consuming. As well, chipping of the ice results in damage to the concrete walls which must then be repaired. To overcome this problem, the present invention proposes the use of a modular heating section comprising a rigid panel having means for securing the section to a navigation lock wall, loading dock, or the like at a location where ice formation occurs, the panel being made from a heat conducting material. The panel includes heater means situated therein, the heater means adapted to distribute heat throughout the modular heating sections.
