Abstract

The present invention relates to an apparatus and method for controlling an auxiliary apparatus of drilling equipment in a drill ship. According to an embodiment of the present disclosure, the apparatus for controlling an auxiliary apparatus of drilling equipment in a drill ship comprises: drilling equipment controller for transmitting a main apparatus execution command to a DC/AC converter in order to operate a main apparatus; and the DC/AC converter for transmitting an auxiliary apparatus execution command to an MCC in order to operate an auxiliary apparatus related to the main apparatus when receiving the main apparatus execution command from the drilling equipment controller, and operating the main apparatus when the auxiliary apparatus is normally operated, wherein the auxiliary apparatus is an apparatus to be operated in advance in order to operate the main apparatus.

Claims

1-56. -56. (canceled)

57. A ship including an apparatus for controlling an auxiliary apparatus of drilling equipment, comprising;

a drilling equipment controller sending a main apparatus execution command to the DC/AC converter to operate the main apparatus; and

a motor control center (MCC) operating the auxiliary apparatus,

wherein the DC/AC converter sends an auxiliary apparatus execution command to the MCC to operate the auxiliary apparatus in response to the main apparatus execution command sent from the drilling equipment controller and the auxiliary apparatus is previously operated for operation of the main apparatus.

58. The ship including an apparatus for controlling an auxiliary apparatus of drilling, equipment according to claim 57, further comprising:

an auxiliary apparatus-related instrument disposed around the auxiliary apparatus and measuring a condition of the auxiliary apparatus.

59. The ship including an apparatus for controlling an auxiliary apparatus of drilling equipment according to claim 58, wherein the DC/AC converter determines whether the auxiliary apparatus is normally operated in response to information regarding a condition of the auxiliary apparatus sent from the auxiliary apparatus-related instrument.

60. The ship including an apparatus for controlling an auxiliary apparatus of drilling equipment according to claim 58, wherein the auxiliary apparatus-related instrument is a pressure gauge provided to a pipe through which a refrigerant is supplied to the main apparatus and the MMC increases a speed of the auxiliary apparatus when the pressure received from the pressure gauge is less than or equal to a first threshold value, and decreases the speed of the auxiliary apparatus when the pressure received from the pressure gauge is higher than or equal to a second threshold value, the second threshold value being greater than the first threshold value.

61. The ship including an apparatus for controlling an auxiliary apparatus of drilling equipment according to claim 58, wherein the main apparatus is a top drive motor and the auxiliary apparatus-related instrument is a flow meter provided to a pipe through which water flows into the top drive driven by the top drive motor.

62. The ship including an apparatus for controlling an auxiliary apparatus of drilling equipment according to claim 58, wherein the MCC receiving information regarding the condition of the auxiliary apparatus sent from the auxiliary apparatus-related instrument and controlling the auxiliary apparatus based on the information regarding the condition of the auxiliary apparatus.

63. The ship including an apparatus for controlling an auxiliary apparatus of drilling equipment according to claim 57, further comprising:
