In collaboration with Bolier, EMHA carried out a combination of inspection, damper replacement and alignment aboard the ferry Lobo Marinho. This work was aimed at optimising the vibration isolation and alignment of the main engines. The result is a more stable installation with improved operational reliability.
Situation
The vessel Lobo Marinho, operating on the daily connection between Madeira and Porto Santo, is equipped with two MAK 16 M32C main engines connected to the foundation via vibration dampers. Over time, insight was needed into the condition of the alignment and the functioning of the existing dampers.
The client’s objective was to:
- Check the current alignment of the main engines
- Assess the condition and functioning of the RD114 dampers
- Take measures where necessary to optimise vibration isolation and alignment
Approach
EMHA started with an inspection on board, assessing both the alignment of the engines and the condition of the dampers. Based on the measurement results and reporting, it was decided to replace the existing dampers.
- Alignment inspected on both MAK 16 M32C main engines
- Technical assessment carried out of the existing RD114 dampers
- New dampers supplied and installed in Viana do Castelo
After installation, our engineers precisely realigned the main engines according to specifications, ensuring optimal power transmission and effective vibration isolation.
Result
After the work, the vessel has an optimised engine configuration with improved vibration isolation and precise alignment.
- Reduced vibration load thanks to new dampers
- Precise alignment of both main engines
- Reliable and stable propulsion installation
Thanks to this targeted intervention, the operational reliability of the installation has been increased and the vessel is optimally prepared for continuous and comfortable use in ferry service.
