Metalships chooses VULKAN couplings for ship hospital "Esperanza del mar"
The couplings assembly was a solution specially studied and adopted for this ship, minimizing their assembly costs
VULKAN Española is proud to have been chosen, both by the Repair Division of the Vigo shipyard Metalships & Docks SAU and by the Owner (Social Institute of the Navy) as the supplier of 2 main couplings VULKAN RATO R + G2F2M with nominal torque 36.0 kN · M between 2700 kW @ 750 rpm MAK 9M25 drive motors and REINTJES WAF 4545 reducers. These couplings have been classified by Lloyd's Register.
The selection of these couplings was supported by the corresponding calculation of torsional vibrations (TVC), carried out by Vulkan, and reviewed and accepted by the Classification Society (Lloyd's Register).
The RATO R + is a highly elastic coupling specially developed for use in drive installations with high torsional demands and good misalignment properties, among many other qualities. The thermal resistance and the reduced aging effects of the elastomer guarantee a long service life and Vulkan Española ensures the availability of spare parts for this ship in the following years.
It is important to highlight that the assembly of the couplings was a solution specially studied and adopted by the Vulkan technical department for this ship, minimizing their assembly costs, since the axles of the reduction gears of the old couplings, greatly simplifying the replacement work of the old ones with these new Vulkan’s.
Likewise, it should be noted that with this solution, it was not necessary to move any of the main equipment’s that interconnect, that is, motor and reducer, since they have the same packaging as the old ones. This ability to find technical solutions tailored for each installation and / or case characterizes Vulkan, saving considerable costs for the shipyard and ship owner. Therefore, Vulkan has been, is and will always be the world's leading and reference brand in elastic couplings.
