Abstract
PURPOSE:To save expenses required for hull's shot blasting and contrive reduction of resistance to the hull by means of applying shot blasting only on the shell plating at lower level than the load water line for the range as far as the hull's shell plating asperity covers almost one fourth of the ship's length from the bow end which greatly contributes to the hull's resistance. CONSTITUTION:Shot blasting is applied only on the shell plating at lower level than the load water line for the range 2 as far as it is approximately one fourth of the ship's length from the bow end which is part of the hull recognized as that the hull's shell plating asperity greatly contributes to the increased in the hull's resistance, and the shot blasting is not applied for other hull's parts. Thus, necessary expenses for applying the shot blasting can be widely reduced to approximately one fourth, and approximately 43% of the increase in the hull's resistance can be lessened. Further, as to the range not alone at the bow part but also as far as it is approximately one fourth from the stern, if the shot blasting is applied, the increase in the hull's resistance can be reduced as much as approximately 70%.
