Alignment services Marine alignment solutions Improving machine efficiency and up-time Shaft misalignment is an important cause of machinery failure. Generally, misalignment is caused by inadequate measurement techniques, an improper foundation, or degradation of the foundation. The alignment of a propulsion unit can also be influenced by deformations in a vessel’s engine room and hull, caused by changes in the operating conditions, working environment or the draft conditions of a vessel. An optimal shaft alignment increases the life of bearings, seals and couplings, but also reduces energy consumption, noise, vibrations and excessive wear. This reduces the chance of costly downtime. SKF is a specialist with decades of experience in solving alignment issues. SKF combines its ShaftDesigner software with a range of technologies to provide precision shaft alignment solutions. Measurements SKF performs include: • Dynamic alignment measurements (on vessels in operation) • Static alignment measurements • Geometric measure

Unique shaft alignment capabilities with ShaftDesigner software SKF performs dynamic, static and geometric measurements for the entire propulsion train, from the nozzle, stern tube bearings, intermediate bearings, through gearboxes, main engines, shaft generators, pumps, pod thrusters and auxiliary power systems, as well as other components of a ship such as the hull, cranes and winches. SKF has developed the innovative ShaftDesigner software package to perform propulsion shaft alignment and vibration calculations. Created in close cooperation with OEMs, classification societies and end-users,...
