Shaft alignment and propulsion shaft bearings


Over the last decade, the shipping industry has encountered recurring challenges regarding propeller shaft aft bearing damage. Such damage runs the risk of diminished or total loss of propulsion capability, costly repairs, off-hire time and loss of reputation – and even increased insurance premiums and/or deductibles.

This makes a robust, well-aligned propulsion shafting installation key to safeguarding the functionality and reliability of the main propulsion, as well as the safe, efficient operation of your vessel.

DNV, leveraging its vast experience in this field gained over the last decades, strives to address the industry’s needs – meaning safe and reliable propulsion shafting with top priority on the propeller shaft aft bearing performance.

Discover how DNV assists you with a variety of class and advisory services, as well as research project results available below.
