Measurement fasteners for offshore use
Extending the life of offshore oil and gas platforms beyond their original design spec through a combination of ‘permanent’ repair work, upgrading existing infrastructure and the development of new and complex strengthening systems, is reported to have resulted in RotaBolt measurement technology being adopted across a number of major projects.
James Walker RotaBolt supplies a range of its measurement fasteners to offshore contractors for use on clamping systems, flanges and jacket reinforcement designs. These vary from M24 bolts on clamps of less than half a metre in diameter, up to M90 bolts that are 3.5m long being used on cable stay clamps that are 130t.
RotaBolts have been used in offshore applications, including subsea, since the mid 1980s. Bolting materials have changed over time in the quest for increased corrosion resistance, but the original technology that assures the correct tension is being achieved has remained unchanged.
