DRILLSHIP WITH COMBINING FORM OF MOONPOOL STRUCTURE CONSIDERING ADDITIONAL RESISTANCE CONTROL

摘要

PURPOSE: A drill ship with a composite moonpool resistance reducing structure is provided to reduce the flow of seawater putting into a moon by deriving the moderate flow of seawater. CONSTITUTION: A drill ship with a composite moonpool(100) resistance reducing structure comprises a flow stabilizing section(110), an inclined part(120), and a sliding control deck(130). The flow stabilizing section is formed by inflow-processing a part of the bottom of a block(140). The block forms an wall side(100a) toward the stem of a moon pool. The inclined part is formed by processing the lower part of an wall side toward the stern(100b) to be downwardly inclined toward the stern. The sliding control deck is formed to be protruded from the wall side toward the stern. The sliding control deck restrains the seawater flow in the moonpool.
