On any type of vessel (large ships, cargo, cruise, yachting) CO.GE.MA. can coordinate, manage, and directly perform the entire set of operations related to the installation of propulsion devices:
We are able to provide a complete and rapid service for all the following types of intervention:
- flattening of reducers and engines base-plates,
- boring of internal and external stern tubes,
- insertion of propeller shaft bearings
- alignment of the whole propeller lines performed with specialized laser systems.
The know-how and the tools available at CO.GE.MA. allow to accomplish with the highest degree of efficiency any kind of adjustment and repair. For example, propeller lines can be checked and aligned with dedicated laser systems without drawing off the shafts, and boring of the stern tubes can be performed on floating ships.
CO.GE.MA. has a remarkable experience in the maintenance of Wartsila engines (170, 20, 22, 38A-B, 46, VASA 32, 32LN, 32GD, 32LNGD,32DF and new generation MAK 20/32/43) and is able to coordinate and perform all the maintenance requested by the manufacturer, as well as specific servicing as – for example – the complete restoration of contact planes on the engine block, always respecting the running parameters and allowances specific to each engine model.
