Marelli Motori is supplying electrical generators for two new vessels designed for exploring polar waters.

This is one of the largest investments in the Norwegian shipbuilding industry in the last century, extremely significant considering the current marine industry outlook.

a leading company for energy

 

This project is particularly important considering that the vessels are built by one of the largest Norwegian shipbuilding groups and were supplied through our customer Rolls-Royce Marine.

Rolls-Royce has a world leading range of capabilities in the marine market, encompassing vessel design, the integration of complex systems and the supply and support of power and propulsion equipment. We are proud to partner with leaders in mission-critical systems for offshore oil and gas rigs, offshore, merchant and naval vessels.

the challenge

These are the first two generators for a project including other two explorer vessels that will bring travellers to unique and exclusive destinations in the world.

The challenge was to design and build technologically advanced electrical machines, which are also environmentally friendly.

the solution


The alternator design has been developed with special attention to any possible static and dynamic structural aspect involved, as well as the clear objective to improve the machine power/weight ratio.

From the start our focus was on getting optimum interface with the structures and propulsion elements with which the alternators will be coupled on board of the vessels. 

Marelli Motori manufactures electric rotating machines for all marine applications where power is required
