PURPOSE: A liftable hydrophone apparatus for a drillship is provided to increase the space utilization of the drillship by simplifying the hydrophone apparatus. CONSTITUTION: A liftable hydrophone apparatus for a drillship comprises a trunk(1), a pipe(2) for lifting a hydrophone(4), a wire rope(3), and the hydrophone. The trunk penetrates through the upper deck and the bottom of the drillship. The pipe for lifting the hydrophone is inserted into the trunk to be lifted. A pulling ring(21) and a pulling ring coupling hole(22) are formed in the upper part of the pipe for lifting the hydrophone. A hydrophone coupling hole(23) is formed in the lower part of the pipe. One side of the wire rope is coupled to the pulling ring, and the other side thereof is coupled to a crane. The hydrophone is coupled to the hydrophone coupling hole. An electric cable(41) wired to the outside of the trunk through the pipe for lifting the hydrophone is installed in a predetermined position. |
