In the early years of North Sea development, torque tools used in factories, refineries and offshore or subsea operations were generally modifications of standard models. It wasn’t long before specific oil and gas torque tools were brought to market, with Norbar one of the pioneers.
Nowadays, a wide variety of torque tools are used for actuation and measurement at offshore and subsea locations, frequently manipulated using remote operated vehicles (ROVs). Robotics has revolutionised the range and scope of projects that can be undertaken in a hostile deep water environment, such as the challenging undersea terrain encountered in the construction of the Langeled pipeline which links the Norwegian Ormen Lange gas field to the UK.
There are a number of issues surrounding the use of torque multipliers in deep sea applications. The first issue is robustness. With Langeled, for example, the fasteners securing the pipe sections had to be tightened to a precise torque using a calibrated instrument ...
