Dynaligner AB Unveils New Cost Saving Device

More than 20 percent of all machinery claims, as well as catastrophic failure, off-hire and repair costs are caused by misalignment – the cause of almost all propulsion train damages.

And it is even getting worse as modern ship design pushes the envelope. However, a Swedish and Dutch invention provides a total elimination of misalignment and a complete modernisation of today’s obsolete shaft alignment practice, said Dynalinger AB in its release.

The revolutionary device, the Dynaligner, guarantees troublefree operation of marine propulsion trains, irrespective of ship operation condition or hull deflections, etc.

As described by Dynalinger AB, the propeller shafting is correctly aligned at all times during ship operation in order to avoid any mechanical behaviour causing inappropriate bearing loads and wear/vibrations.

The patented invention particularly focuses on, protecting the engine/gear, intermediate bearings and the sterntube bearings.

The Dynaligner  replaces the traditional one-off procedure of manual shaft alignment at the shipyards. Instead, continuous and automatic adjustment of the bearings are performed during ship operation. The ingenious core of the whole invention is how to keep the bearing house solid to the foundation structure during adjustments. Controlling software is included.

The installation can be carried out on new builds as well as on existing vessels in service when the vessel is in dock for propeller shaft survey.

“For the ship owner, the most important economic advantage of using Dynaligners is saving all the costs brought about by misalignment, not least the class-required regular stops for tailshaft survey in dock. There are no delays during the new build phase due to shaft alignment procedure. The troublesome jack and sag&gap methods are not needed anymore. The propeller shafting can be installed before the superstructure is mounted on the hull, which will save a lot of time,” Dynalinger AB explained.
