The invention provides a split-type drilling ship, and further provides a manufacturing method of the split-type drilling ship. The split-type drilling ship comprises two floating body ships, a drilling module base and a drilling module, wherein each floating body ship is provided with a power system, an anchor machine system and a ship navigation system; the drilling module base is provided with a structural base and is fixedly connected between the two floating body ships; the drilling module comprises a drilling platform and drilling equipment, the drilling platform is arranged on the drilling module base, and the drilling equipment is respectively arranged on the drilling platform and the two floating body ships; and the power system is respectively connected with the ship navigation system and the drilling equipment. The split-type drilling ship and the manufacturing method of the split-type drilling ship not only can solve the problem that the drilling equipment needs to pass through rivers and the like in enclosed sea areas and accordingly the drilling equipment can not freely come in and go out, but also can solve the defect that when a non-power platform such as a self-lifting-type drilling platform works, if the working position is changed, navigation must depend on tug, and also can avoid windstorm working conditions or other bad sea conditions.
