Efficient shaft generator for bulk carriers

The variable speed permanent magnet shaft generator solution consists of the variable frequency drive WE Drive and the direct drive permanent magnet shaft generator, which utilises an efficient generator type. The solution significantly decreases the vessels fuel consumption, operation expenditure and maintenance cost by turning off the Auxiliary generator during sailing. In Power Take Out (PTO) mode, electrical power is generated with shaft generator driven by the efficient two-stroke main engine, which also drives the main propeller of the vessel.

“It will bring significant changes from the traditional system, in terms of operation performance, fuel consumptions and environmental protection,” the general manager of Vulica Shipping, Atul Sabharwal stated. “This is the cheapest and quietest form of power generation on board and capable of carrying the full sea load of the vessel. The shaft generator is very steady within the designed rpm range.”

Lightweight

WE Drive has compact modular design and dedicated power management system. It can be operated alone or in parallel with auxiliary generators. The permanent magnet shaft generator contains Neodymium-Iron-Boron magnets with a very high flux density to make it more compact, lightweight and smaller in size.

Ireland and Donald M. James were constructed by Jiangsu Hantong Shipyard, China and delivered to US-headquartered Vulica Shipping in March and May respectively.
