StatoilHydro's tensioner usage told in handbook

摘要

A free handbook depicts StatoilHydro's choice of Superbolt Supemut Tensioners as a recommended bolting alternative. "Reliable Securing" booklet indicates the tensioners are constructed such that standard nuts are replaced by "stretch nuts" with integrated jackbolts and washers. Their use can be very beneficial in terms of HSE because only hand tools are needed for fitting and dismantling. Rigging of heavy wrenching equipment and possibly use of sledgehammers during dismantling is avoided.
