发明名称 Blowout preventer and guideline handling
摘要 Apparatus and method are provided for handling guidelines for an ocean drilling platform rig. A cart for guiding the lines rides on a track and can be moved away from a drill well when a blowout preventer is moved into place over the well on its own cart. When the load of the blowout preventer is transferred to a drilling string, the blowout preventer support cart is moved away from the drill well and the guideline handling cart is positioned over the well. The guidelines are then attached to a guideline frame on the blowout preventer.
