2 MacGregor part of Cargotec Cargotec is a leading provider of cargo handling solutions. Our products are present in every major cargo hub worldwide. They are used in ships, ports, terminals, distribution centres, heavy industry and in on-road load handling globally. Cargotec's business areas MacGregor, Kalmar and Hiab are recognised market leaders in their fields. Cargotec Group Sales 2013: EUR 3.2 billion Approximately 11,000 employees Cargotec and its business areas have operations in more than 120 countries and in more than 750 sales and service locations worldwide With this unique global coverage, customers can be served locally ensuring the continuous operation of their products 16 September,

3 Kristiansand site: Advanced Load Handling & Offshore Service Cargotec acquired Hydramarine A/S in 2007, today forming MacGregor Norway R&D, Sales, Design, Sourcing, assembly, testing, installation, training center, service Employees: ~700 in Norway (~250 in Kristiansand) 16 September

5 Moving into a New Market Offshore Crane for wind turbine services 16 September

6 Moving into a New Market Offshore Crane for wind turbine services Current technologies for load handling to Offshore Wind Turbines Fendering systems (boat ramming into the foundation) Gangways (ship deck to platform) Relatively small compensated cranes Crane on hexapod with 6 DOF compensation system Etc. All compensated systems currently in service have a small payload and range Max payload ~0.5 6m distance The New MacGregor Crane for Offshore Wind Turbine Services beats this by a factor of 10! 3 DOF compensation system Max Payload: 5 25 m distance and 35 m above deck 16 September

Customer Request for Service and installation vessel for wind turbines Customer requirements Work in harsh weather and sea conditions (HS=3) Load: 5 ton, cubic formed container ~2.5x2.

7 Customer Request for Service and installation vessel for wind turbines Customer requirements Work in harsh weather and sea conditions (HS=3) Load: 5 ton, cubic formed container ~2.5x2.5x2.5m Fixed unloading platform Extremely small landing area, located well above sea level Resulting concept: Telescopic, slewing and luffing crane 360 slewing angle, 25m max outreach 35m lifting height 5 ton winch mounted on jib Snubber on crane tip Removes pendulum effects 3-axis motion compensation system Crane tower to be kept vertical and load kept at specified height 16 September

8 Why use a 3D compensation system? Disadvantages of alternative technologies Jack-up with fixed crane Vessels are often big and slow For small lifting operation the jack-up time is significant Energy And fuel consumption are high Etc. A standard offshore Crane without 3D compensation system The Lifting operation in question, can only work in good weather conditions High risk for crew handling the load High risk of damage to equipment in unloading area Etc. 16 September

9 Emerging Challenges Concept analysis Several design iterations were performed Simulation Model Comparison with test results DNV demanded a dynamic load factor of 2.7 Crane size increased from 1.6m tower diameter to 2.2m Weight of crane goes up All hydraulic and electrical components increases in size Paradigm: Design the compensation system for a worst case scenario: If the compensation system doesn t work! When the system works; some components only uses % of their performance Risk analysis Risk of heavy damage to material if essential components malfunctions Critical components are run through a self-test cycle before entering compensation mode Redundancy and double sensors circuits Test condition Not possible to test compensation system while crane was assembled on land, (would require an enormous hexapod) 16 September
