Abstract
A member in the form of a ring connected by radial fins to central hub includes a heater at least for its lower surfaces so that in operation it melts the ice of the iceberg (starting from the top surface thereof) and sinks therethrough with the ice re-freezing above it. The member also includes a central tube removeably attached to the central hub. The tube is fed after the sinking member to provide a vertical shaft through the iceberg. The ring serves to remove a slab of larger diameter than the tube from the lower surface of the iceberg in order to receive a propulsion unit.
