Introduction
Auxiliary Wind Propulsion
• Depending on wind conditions up to 50% of service power is replaced with wind propulsionHYBRID system
• Average savings depend on configuration and on the wind conditions of the route / route area
• Norsepower’s technology is well suited to:• Tankers• Bulk cargo vessels• Ro-Ro, Ropax, Ferries, Short Route Ferries• Cruise ships
• Compatible with all other ways to save fuel

Rotor Sail
Physics of the Rotor Sail: Magnus Effect explained
• When wind meets a spinning object, it results in a high and low pressure differential, which creates thrust at a 90 degree angle to the wind
• Flettner (DE) and Savonius (FI) discovered the fundamentals of a “Flettner rotor” in 1920s
• Norsepower has modernisedthe technology entirely by introducing high tech materials and automated operation

Approach
Start
Implement
Analyze
• Project schedule setup
• Identify wind conditions, based on historical
data for the sailing area!
• Install systems
-VFD, NAPA, Rotorsails
• Do reference period 3-6 months
• Do trial period 6-8 months
• Perform analysis of the fuel savings
Experiences from M/S Estraden
Technical performance
• Thrust performance as expected
• System availability exceeds 98%
• Noise and vibrations remain at low levels
• The automation system works as intended
• Less input power than calculated. Abt. 7%.
Operator experiences
• The rotor has a stabilising effect on the roll motion
of the vessel
• No recognisable effect on rudder angles or leeway
• The system is easy to operate and the crew is able
to use it after minimal training
Fuel saving results
• Independent research body (NAPA Oy from Finland) has
measured fuel consumption and propulsion power requirements
in different conditions
• Regression analysis shows, that during the analysis period the
Rotor Sail has reduced the propulsion power consumption
significantly
• While using two Rotor Sails, the net fuel consumption during
trail period was reduced in average by 6,1%,
equalling 400 t of fuel and 1200 t of CO2
• During the years, a net fuel saving of abt. 5 % has been
observed
• Payback period: <4 years (MGO, 650 USD/t)

Viking Grace project: phases
• One 24x4 Rotor Sail was installed as a retrofit onboard Viking Line’s Viking Grace in April 2018
• The installation of the foundation and cabling work were done during a docking in January 2018
• The performance measurement campaign was started on 10 April 2018

• Two Rotor Sail performance reports were ordered from independent third parties, and both of them have recently issued their final reports.
• In addition to this, Norsepower has conducted its own strain gauge analysis. Strain gauges were installed, calibrated and monitored by an external provider.

Maersk P-class tanker project
• Two 30x5 Rotor Sails were be installed in August 2018 as a retrofit on a Maersk P-class oil products tanker (109,647 DWT)
• The combined projected average fuel savings on typical global shipping routes are expected to be around 10%.
• Norsepower estimates that up to 20% average fuel savings are possible on routes with favourable wind conditions

”Bore Ltd has a great interest to reduce emission in shipping. Dispite the
relativly low output of BWind 2 (340 W@10 m/s) Bore is acctivly involved
in the developing and suporting the road towards BWind20, still beeing at
a kW range when propulsion today is at MW”
It’s our goal to find ways to establish sustainable shipping with
minimal impact on our environment.
