3 Introduction to Norsepower 24/11/2017 3

4 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 in to Bore s M/S Estraden The results from M/S Estraden have confirmed the expected performance of the Rotor Sail Solution. Average fuel savings exceed 6% on the route between Rotterdam and Teesport (UK) Next delivery projects are ongoing 24/11/2017 4

5 Auxiliary Wind Propulsion Depending on wind conditions up to 50% of service power is replaced with wind propulsion HYBRID 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 24/11/2017 5

6 Physics: Magnus Effect (1/2) Visit to see the video Start from 00:20 Jump from 00:35 to 00:55 24/11/2017 6

7 Physics: Magnus Effect (2/2) When wind meets a spinning object, a high and low pressure differential is created, creating thrust at 90 degree angle to the wind Flettner (DE) and Savonius (FI) discovered the fundamentals of a Flettner rotor in 1920s Norsepower has modernized the technology entirely by introducing high tech materials and automated operation 24/11/2017 7

8 Norsepower Rotor Sails Main components Composite rotor Internal support steel tower Upper support main bearing Motor and drive for rotation Lower support rollers Foundation on ship s deck Properties Rotor heights 18m, 24m, 30m Rotor diameters 3m, 4m, 5m Weight 20 45t Revolution speed max. 250rpm Average El. consumption 15 35kW 24/11/2017 8

9 Rotor Sails on board M/S Estraden 24/11/2017 9

10 Experiences from M/S Estraden Technical performance Thrust performance as expected System availability exceeds 99% Noise and vibrations are on low level The automation system works as intended Operator experiences The rotor has a stabilizing effect on the roll motion of the vessel No recognizable effect on rudder angles or leeway The system is easy to operate and the crew is able to use it after a short training Average annual net savings: 6,1% (400 t of fuel and 1200 t of CO2) Payback period: 5 years (MGO, 400 USD/t) 24/11/

11 Maersk P-class tanker project Two 30 x 5 Rotor Sails will be installed in 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 24/11/

13 Maersk Tankers at a glance: +200 Customers as well as +60 partners 3100 Employees globally 9 Offices across the globe 1,664 Invested capital (USDm) 887 Revenue in 2016 (USDm)

14 We play a key role in the global energy value chain Our primary playing field Exploration & Production Shipping Crude Tankers Refining Shipping Product Tankers Distribution Retail We transport energy such as: gasoline and diesel for our cars jet fuel for the planes we travel in fuel for heating and when processed, a vital part of our clothes and mobile phones Global product freight of oil products in % tonnes per product type 19% 11% 8% 30% 32% Diesel Fuel Oil Gasoline Jet Naphtha Key products: Million tonnes/year Diesel Fuel Oil Gasoline Jet Naphtha Source: Wood Mackenzie

15 Reason for our technology interest We are today a leading product tanker company, operating the second largest fleet in the world. Through technology innovation, we want to continue being technology leaders, operating best in class, while simultaneously improve our green profile Desire to be a Technology leaders: Providing early learnings of integration, drive efficiency improvements along with collecting knowledge of optimal design for future newbuilds Potential of a large monetary gain: potential CO2 footprint & fuel saving reduction of 10%, not matched by other technologies on our radar. Proving our environmental image: Showing investors and industry an innovative and active Maersk drive in CO2 reduction through heathy business.

16 Adapting NP technology onto tanker vessels New technology with lots of new technical risks and challenges to understand and mitigate....with severe consequences to avoid Air draft and bride heights Blind angles COLREG and flag state exemptions Risk analysis & mitigation actions Operational constrains (visibility, ports etc.) ATEX approved design Foundation design & strength approval

17 A perspective of project scale Maersk pelical LR2 Tanker vessel: Adding 170 T of extra steel and composites onto vessel Increasing height with ~ 8 meters Potential of adding more than 5 MW extra thrust Rotors Air draught: m in ballast arrival Total height (from bottom): 57,6 m Big Ben 96 m (Clocks: 54,9 m)

18 The need of ETI to realize the technology Large investment with high uncertainties and risks New technology to Maersk as a non- R&D company High influence on current operational setup Need of external partner to realize the technology and make it commercial viable

19 Partnership learnings page 19 The project have required a complex partnership with both learnings and challenges to overcome. Broad leanings for all partners in the coorperation across countries and cultures. Joined spirit of wanting to coorperate and having the tehnology succed. Coorperation of several partners that are used to being the single point of control Many misallignments in objectives, processes and procedures.

20 Todays project status and achievements Main milestones achieved June 2017 LR facilitated HAZID workshop and risk assessment July 2017 MPA approval of application for COLREG exemption (visibility & line of sight) Sept Foundation design and load report finalized Sept Assembly of first rotor Nov CLASS approval of Electrical and structure finalized Nov Vessel drydocking and foundation installation
