Company

Background and current status

• Norsepower has brought to market the first proven auxiliary wind propulsion system

• The first Rotor Sail was tested on land during 2014

• The first commercial project with two Rotor Sails was delivered between 2014-2015 to Bore’s M/S Estraden

• Viking Line’s cruise ferry Viking Grace started Rotor Sail assisted cruises in April, 2018

• Maersk Pelican started Rotor Sail -assisted voyages in August, 2018

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

Bore, part of the Spliethoff Group since July 2016

• The Spliethoff Group

operates a large and

modern fleet of more

than 100 vessels

ranging from 2,100 to

23,000 tonnes

• The Spliethoff Group

is one of the largest

Rotor Sails on board M/S Estraden

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

Flashback: Stockholm in 1926 and 2018

• Anton Flettner’s Rotor ship ”Buckau” visited Stockholm in 1926

• The next Rotor ship in Stockholm was Viking Grace on 13 April 2018

”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.
