06 Wallenius – a green pioneer Wallenius has a reputation for being one of the “greenest” shipping companies in the world. Jesper Lögdström, Design Manager – Stability & Hydrodynamics of Wallenius Marine, tells Report how going green involves more than painting vessels.


10 Integrated design approach helps reduce fuel consumption and emissions A number of design issues that can achieve fuel savings for new or for existing vessels are explored.


12 New Renewable ENergy Team (RENT) launches MARIN forms a new team of experts to answer your questions about advances


in the offshore renewable energy field.


13 Sustainability and renewable energy - a key focus MARIN applies its tools and experience to the design and hydrodynamic analysis


of water turbines.


14 Safety assessment for offshore wind farms with SAMSON MARIN examines the impact wind farms have on shipping.


15 SWAY’s special deep-water wind turbines Norwegian renewable energy company SWAY has developed a concept for wind turbines


that can produce power in deepwater locations. Report outlines a series of model tests.


16 Green energy from green water Wave energy represents a significant untapped energy source. MARIN looked at the


offshore industry for inspiration as to how it can be better utilised.


18 Exactly how foul is the fouling problem? MARIN grapples with slime to discover its impact on ship performance.


20 Tackling tug emissions with Green Tug and E3 projects


MARIN is working on several research projects that aim to reduce emissions from harbour tugs. Report outlines the projects.


22 Two new JIPs launch An update on two of the latest Joint Industry Projects, one investigating the mysteries of


the moonpool and the other, looking into the efficiency gains of two and three bladed propellers on slow-steamers.


23 Assessing the value of kite traction Pilot simulations get underway following increasing interest in kite traction.


24 VIRTUE boosts the role of CFD in ship hydrodynamics The work of the 6th-Framework EU project VIRTUE is highlighted.


26 Inland navigation plays an increasingly important role Report outlines MARIN’s intensified focus on the inland sector.


Dear Readers,


Welcome to the latest issue of Report, which as you will see has a clear green focus. As concern about climate change grows and the pressure to reduce greenhouse gases intensifies, many of you are working on initiatives designed to save fuel and cut back on CO2


emissions. Some interesting projects we are working on are outlined in this edition.


Report has also been fortunate enough to speak to one of the green pioneers of the maritime industry, Swedish shipowner, Wallenius. Jesper Lögdström, Design Manager – Stability & Hydrodynamics of Wallenius Marine, outlines the many initiatives the company has underway in a bid to improve the environment for now and for future generations. He shows that it is not necessarily easy being green, but it requires dedication and commitment throughout the organisation.


MARIN too, is addressing sustainability issues. Recently, we formed the dedicated Renewable ENergy Team (RENT). This specialist team will help clients that are interested in the offshore renewable energy field. We have already been involved in studies for more than 30 offshore wind farm locations. Our basins were also used to test SWAY’s deep-water wind turbines and this project is highlighted. Wave energy comes under focus when MARIN studies the possibility of getting energy from green water.


Several of the projects in this issue focus on ship resistance and propulsion and their impact on fuel efficiency, while reducing emissions in the towage sector is the main aim of Green Tug and E3


.


If you would like more information about any of the articles in Report, you are most welcome to visit us at several conferences and exhi- bitions coming up. Or at the Open Day this year at our Wageningen headquar- ters on October 10.


We do hope to see you all soon and look forward to dis- cussing your latest initiatives.


Arne Hubregtse President of MARIN
