摘要

PURPOSE: A jig for testing the top driver torque of a drillship is provided to improve working efficiency by easily installing a jig for testing the top driver torque. CONSTITUTION: A jig for testing the top driver torque of a drillship comprises a drill pipe(10), a plurality of rod plates(20), an auxiliary plate(30). The drill pipe takes a role of a rotary shaft. The load plates are formed in the lower outer circumference of the drill pipe in all directions. The load plate has predetermined length along a longitudinal direction of the drill pipe. The auxiliary plate is installed in between the load plates. The auxiliary plate is projected to a transverse direction in the outer circumference of the drill pipe. Both end parts of the auxiliary plate are joined to the load plates.
