摘要

PURPOSE: A drilling ship having a gantry type derrick is provided to increase the load weight by the enhancing of the stability of a ship since the installation height of a derrick is low. CONSTITUTION: A drilling ship comprises a derrick(100) and a lift unit(105). The derrick is composed of a first column(101), a second column(102), and a horizontal beam(103). The first column is installed on the upper deck(21) of the ship. The second column is separated from the first column and is installed on the upper deck. The horizontal beam connects the upper part of the first column to the upper part of the second column. The lift unit is installed on the horizontal beam and lifts a pip member for a drilling operation. A setback area(106) is arranged in the first column. The pipe members are loaded on the setback area in a longitudinal direction.
