    Znaczenie prób obciążeniowych układów wyciągowych urządzeń wiertniczych i eksploatacyjnych

    Mast and drawworks system for running and pulling drill string, holding it at drilling, casing and tubing running operations influences on mast/derrick load value. Additionally high load of drawworks can be exerted during rig up operation. Load tests of mast and drawworks performed give impact of loading forces on mast framework behaviour, eventuality of design defects and critical deformations. Load tests decrease risk for implementation of systems uncomplying with basic safety requirements.
