发明名称 SYSTEMS AND METHODS INCLUDING INTEGRATED HOISTING SYSTEMS
摘要 This disclosure includes systems and methods for hoisting and/or lowering oil and/or gas well-related loads. Some systems include first and second hoisting systems and a load sharing device configured to be coupled to each hoisting system such that, when a well-related load is coupled to the load sharing device, each hoisting system supports a portion of the weight of the well-related load. In some systems, each hoisting system includes a frame, a crown block coupled to the frame, a travelling block coupled to the crown block via a drill line, and a draw-works coupled to the drill line such that actuation of the draw-works moves the travelling block relative to the frame, and the load sharing device is configured to be coupled to the travelling block of each hoisting system. In some systems, each hoisting system is associated with a respective well operation center of an oil rig.

主权项 1. A system for hoisting and/or lowering an oil and/or gas well-related load, the system comprising: first and second hoisting systems, each having: a frame;a crown block coupled to the frame;a travelling block coupled to the crown block via a drill line; anda draw-works coupled to the drill line such that actuation of the draw-works moves the travelling block relative to the frame; and a load sharing device configured to be coupled to the travelling block of each of the first and second hoisting systems such that, when a well-related load is coupled to the load sharing device, each of the first and second hoisting systems supports a portion of the weight of the well-related load.
