What is the potential consequence of improper torque tightening of bolts on a WEC?

Improper torque tightening of bolts on a Wave Energy Converter (WEC) can lead to several potential consequences. Undertightening bolts can result in loosening due to vibration and dynamic loading, which is typical in the harsh marine environment. Loose bolts reduce the clamping force, causing the joint to weaken and potentially leading to slippage, fretting, and eventual failure of the connection. This can result in structural instability, misalignment of components, and even complete separation of parts. Overtightening bolts can cause the bolt to yield or fracture, reducing its load-carrying capacity and potentially damaging the connected components. Overtightening can also strip the threads in the bolt or the tapped hole, rendering the joint unusable. In addition, improper torque tightening can lead to uneven stress distribution across the joint, which can cause premature fatigue failure. Therefore, it is crucial to use calibrated torque wrenches and follow the manufacturer's recommended torque specifications when tightening bolts on a WEC to ensure the structural integrity and reliability of the device. Applying the correct torque ensures the joint is properly preloaded, providing adequate clamping force and preventing loosening or failure.
