Does the driller have an adequate unobstructed view of the drilling area on drill floor, including the derrick, drilling equipment and pipe-handling equipment?
The driller's cabin should be designed so the view to the drilling area from the DC is free of obstructions to for instance the top drive, racking arms, cat-walk, iron roughneck, personnel etc. It is often seen that the view is obstructed by beams that support the driller's cabin structure.
