Description

DRILLSHIP {DRILLSHIP}

The present invention relates to a drill ship.

The drill rig requires a Derrick structure for drilling. Derrick usually has the same shape as a high tower. Because these deriks are quite high, drill rigs can be a major obstacle to passing through places with air draft limitations.

For example, in order to pass through the Panama Canal or the Suez Canal, it is necessary to meet the Air Draft required by the Flight Administration, as it may pass under certain bridges during canal passage.

Therefore, if the height of the derrick included in the drill ship does not satisfy this requirement, the drill ship may not pass through the Panama Fort or the Suez Canal.

Korean Patent Laid-Open Publication No. 10-2011-0013045 (2011.02.09, Derrick and drilling line including it)

The embodiment of the present invention is intended to provide a drill ship capable of adjusting the height of a drill derrick as required.

According to one aspect of the present invention there is provided a hull comprising a door hull, a drill that is installed on the drill floor of the hull and the lower portion is inserted into the interior of the door frame and can be supported inside the door frame, Is provided.

Here, a stepped portion protruding from the upper portion is formed in the interior of the door frame, and the sectional area of the doorway deriving portion is smaller than the upper opening area of the door frame and larger than the step opening area of the door frame.

The drill ship can be supported on the drill floor by the rotation of the drill derrick with the drill derrick raised and each corner of the drill derrick deviates from the opening of the portal.

The drill ship can be supported on the drill floor by turning the upper surface of the drum while the drill derrick is lifted so that each corner of the drill derrick deviates from the opening of the drum.

The drill ship can be supported on the drill floor by the support bar protruding from the opening face of the door frame with the drill derrick raised.

The elevating portion may include a crane installed in the hull.

Further, the elevating portion may include a jack-up device installed on the hull.

According to the embodiment of the present invention, since the lower part of the drilling deck installed on the drill floor can be inserted into the interior of the door, it is possible to realize a drill ship which can adjust the height of the drilling derrick if necessary.
