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 Sweden’s Dynaligner AB said, adding that the problem is getting worse as modern ship design pushes the envelope. However, a Swedish and Dutch invention aims to eliminate misalignment, modernizing today’s shaft alignment practice. The device, the Dynaligner, is said to offer troublefree operation of marine propulsion trains, irrespective of ship operation condition or hull deflections, etc.
