2. Background Joint project with system integrator NES:
Our first electric propulsion case for direct-drive PMMs
First genset case and first case for a large commercial fishing vessel
Owned by France Pélagique, part of the Cornelis Vrolijk Group
Pelagic trawler – replaces outdated vessels in service since the 80s
Design & construction: Havyard Ship Technology, Norway, & ASD, Denmark
Vessel delivery: 2019

3. Challenge Fleet modernization to meet growing demands
EU demands power-management systems aboard ship
Europe’s ports increasingly concerned about who they want quayside
Catching fish requires speedy, maneuverable trawlers
Together, propulsion and generators normally mean noise or vibration – a problem for crew and fish
Short delivery time

4. Solution
Two The Switch permanent magnet propulsion motors (2,250 kW); and two permanent magnet gensets (3,055 kW)
PM gensets have less structural noise
The PM machines feature an extremely compact size and low weight, while maintaining high efficiency
Weight savings from just the 2 propulsion motors is more than 35 tons
Auxiliary generators onboard operate at variable speeds, cutting fuel use
On propulsion motors, the competitors were offering conventional-type (asynchronous) machines, which had more than double the weight, thus making the weight saving just from the two propulsion motors to be more than 40 tons.

5. Results
Fully optimized motors and generators delivered in a very short time
One of the most modern fishing trawlers with reduced emissions 
Noise levels brought below DNV GL regulations
50% more compact solution than competing arrays; by cutting the vessel weight by 35 tons, this allows 35 tons of fish more in each haul
2–4% better efficiency over conventional motors at the nominal point
This results in significant fuel savings over the vessel lifetime
Excellent reliability as the rotor is very simple  low risk of failure
Higher maintenance savings with brushless PM machines
Fuel-efficiency testing raised eyebrows.
 Instead of having the generators running at full speed constantly, these ones will be able to vary the speed and power output to what is actually required, so no excessive waste.
PM machines need minimal maintenance as basically the only wearing parts are the bearings and cooling fan motors.
Motors tested well for thermal behavior and exceeded expectations.
