& prevents turbocharger damage
In October 2007 the German shipping company Hapag-Lloyd installed an advanced OPENpredictor™ condition monitoring solution on three 4,000 teu containerships in service since 2002: Dublin Express, Glasgow Express and Liverpool Express. The systems monitor both the vessels 9-cylinder Wärtsilä engines and their Napier turbochargers.
Hapag-Lloyd chose bearing wear monitoring from Rovsing Dynamics because it enables the crew to plan corrective actions in due time, and because it is more flexible than other solutions. It offers many expansion options like monitoring of other machinery and integration of predictive maintenance information with other systems.
Within 6 months this investment paid off, when OPENpredictor™ detected increased vibration level of one of the turbochargers at Glasgow Express. The warning was fortunately given in due time for the crew to replace the turbocharger’s turbine rotor. Thereby they avoided the risk of significant consequential damage, which could have resulted in significant repair or turbocharger exchange costs.
The OPENpredictor graph shows how the turbocharger's vibration level increased beyond the yellow alert level and the red alarm level.
Following the successful field test on the three vessels in service, Hapag-Lloyd decided to also equip their six new 8,750 teu containerships under construction with an OPENpredictor™ online condition monitoring solution for the 12-cylinder MAN B&W main engines. The objective is to save time, cost and manpower by avoiding open-up inspections.
