DRILLSHIP OF DUAL FUEL ENGINE TYPE

摘要

According to the present invention, an oil drilling ship, propelled with dual fuel, is capable of simplifying the design of the oil drilling ship, thereby reducing the size of the drilling ship and satisfying a DP2 condition by simply arranging pipes and devices while minimizing a change of the arrangement of an existing oil drilling ship when applying a dual fuel engine, using gas fuel as main fuel, to the oil drilling ship. Moreover, the present invention is capable of enhancing the safety and convenience of supplying fuel to the dual fuel engine as well as reducing fuel costs through gas fuel, and easily satisfying fuel gas emission regulations for ships. The oil drilling ship comprises: an engine room installed in a hull of the oil drilling ship, and including an engine; a fuel oil storage tank storing fuel oil to be supplied to the engine; and a gas fuel storage tank storing liquefied gas fuel to be supplied to the engine. One of the gas fuel storage tank and the fuel oil storage tank is placed between the engine room and the stern of the hull, and the other one is placed between the engine room and a moon pool.
