Designed to break

Designed to break James Walker RotaBolt has successfully developed the BreakBolt - a unique safety fastener that is designed to deliberately fail at a predetermined tension level. The new fasteners also incorporate the award winning RotaBolt technology, constantly and accurately measuring the tension across the bolted joint at the same time. The BreakBolts have been supplied to Vetco and are currently being used on specific offshore well head applications where a breakaway potential was required as a primary safety feature in the design of the riser system. The BreakBolt is engineered to fail at a pre-set ultimate tensile load and has a specially machined waist, which reduces the tensile stress area, allowing the bolt to shear once it has reached the required tolerance. The bolts are tested to destruction at an independent test house and are certificated to their desired break load. "Designing a RotaBolt that would perform a controlled break under set conditions seemed a relatively straightforward task to begin with," comments Rod Corbett, managing director of RotaBolt, "but it has been a major learning curve and has taken a great deal of research and development to perfect the procedure. We are delighted that the new BreakBolt not only incorporates all the advantages of our original technology so that it constantly monitors tension, but it also performs exactly as required, breaking away as specified under very challenging conditions." The bolts have been supplied by Vetco as part of wellhead applications in the North Sea and in Nigeria. Vetco's clients had requested that the umbilical riser systems should have a break safety feature built into the design.
