Abstract:
1. A hydrocarbon drilling tubulars storage and handling system, said system comprising: first and second rotary storage racks, each rotary storage rack being rotatable about a vertical axis and having storage slots for storage of multiple tubulars in each rotary storage rack in vertical orientation, the first and second rotary storage rack each including a drive to rotate the storage rack about the vertical axis of the storage rack, a tubulars racking device positioned between the first and second rotary storage racks, said racking device including a rotary structure that is rotatable about a vertical axis of the rotary structure, the rotary structure supporting at a first side thereof a first tubular racker assembly and at a second side thereof a second tubular racker assembly, each tubular racker assembly including one or more gripping members adapted to grip a tubular, and a drive to rotate the rotary structure about said vertical axis of the rotary structure thereby simultaneously rotating the first tubular racker assembly and the second tubular racker assembly about said vertical axis of the rotary structure, wherein in a first rotary position of the rotary structure the first tubular racker assembly is operable to place a tubular in and remove a tubular from the first rotary storage rack, and the second tubular racker assembly is operable to place a tubular in and remove a tubular from the second rotary storage rack, and wherein in a second rotary position of the rotary structure the first tubular racker assembly is operable to place a tubular in and remove a tubular from the second rotary storage rack, and the second tubular racker assembly is operable to place a tubular in and remove a tubular from the first rotary storage rack.
