ABSTRACT:
Apparatus is provided for lifting equipment or tubulars below the deck of a platform or a drilling rig. Lifting force is monitored with a load cell. A portable platform is added above the deck of an offshore platform to allow running or retrieving a string of tubulars through the deck, thereby avoiding the need to deploy a workover or drilling rig to the platform.
