PURPOSE: A full guiding system for risers of a drillship is provided to stably move the risers because the risers are fully guided from the inside of a cargo hold to a riser transfer part. CONSTITUTION: A full guiding system for risers(110) of a drillship comprises a gantry crane part(121), an elevation part, and a riser transfer part. The gantry crane part is installed inside a cargo hold to transfer the risers loaded inside the cargo hold to a parking position and has a winch(122) and a riser clamp(123). The elevation part is installed outside the cargo hold right above the parking position and has a winch and a riser clamp to lift the risers positioned in the parking position to the outside of the cargo hold. The riser transfer part transfers the risers lifted by the elevation part to a drill floor. |
