Abstract:To ensure the integrity of offshore jack-up rigs, a novel torque transducer has been developed through 18-month-long joint collaborations cross industries globally.A medium size offshore jack-up rig uses a set of fifty-four units of AC-driven jacking systems to jack the platform up and down. Due to inevitable manufacturing tolerances and poor correlation between motor current and its torque at standstill and near-zero speed, the synchronization and even load distribution among the fifty-four climbing pinions o… Show more
