MS Konningsdam cruise liner fuel package

On behalf of our client we travelled to Barcelona cruise liner port to investigate vibration and pulsation on the MS Konningsdam cruise liner fuel package supplied by Alfa Laval.

We were asked to investigate the operation of the fuel dampers. We connected our Hydac HMG into circuit to measure the system pressure and pulsation / damping effect. It was found that on three of the dampers the pre charge pressure was low and the damper was having no effect on the system.

The ship requested that we fit new in stock dampers and check the pre charge. Once installed and the fuel package operational we measured the damping / pulsation and it had reduced massively due to the new Hydac dampers and correct pre charge.
