18 July 2017Stabbing board
A temporary platform erected in the derrick or mast some 20 to 40 ft (6-12 m) above the derrick floor. The derrickman or another crew member works on the board while casing is being run in a well. The board may be wooden or fabricated of steel girders floored with anti-skid material and powered electrically to be raised or lowered to the desired level. A stabbing board serves the same purpose as a monkeyboard but is temporary instead of permanent.
