Finnish engineering company, Norsepower announced that it has received €3million in investment from a syndicate led by venture capital fund Power Fund III and has installed a second rotor sail on Bore’s Ro-Ro vessel MS Estraden. NAPA data analysis and fuel-saving verification leads to €3 million investment and first commercial order for a Flettner rotor.
A single Norsepower Rotor Sail was installed on the 9,700 DWT Ro-Ro carrier in early 2015. Although the weather conditions were largely calm over the three-month trial, data analysis from vessel performance monitoring and verification software, ClassNK-NAPA GREEN, demonstrated that the rotor sail delivered clear and significant savings of 2.5%.
Based on this evidence, Bore has ordered a second installation; the first commercial order for a Flettner rotor in shipping. Doubling the rotor sails has now proven to double fuel savings; NAPA recorded a 6.1% reduction in fuel consumption, avoiding 1,200 tonnes of CO2emissions annually.
Measurement, analytics and third-party verification has helped Norsepower evolve its rotor sail from an innovative system for trial, to a proven and marketable fuel efficiency technology with a clear business case. In addition to the expanded market potential, this evidence has also helped Norsepower increase its enterprise value and secure the future of the business. A syndicate led by Power Fund III, a Clean tech venture fund managed by VNT Management, has invested €3 million to support Norsepower’s growth and market expansion.
Tuomas Riski, CEO, Norsepower commented:
“Since delivering our first proven application with Bore last year, our business has grown from strength to strength. With this significant investment from VNT and our first commercial installation, we have now cemented our position as leaders in the growing wind technology market. Objective data and impartial verification of the fuel savings delivered by the technology has been absolutely critical to this evolution and will remain central to the way in which we work with shipowners and operators.”
Jouni Salo, Product Manager, Shipping Solutions, NAPA commented:
“Independent verification of Norsepower’s technology has required a significant and complex analysis process. The operating route of the vessel posed many challenges from differing wind conditions to varying sea depths, all of which impact fuel consumption and had to be accounted for with randomised trialling, robust data collection and advanced statistical modelling. The results, however, have made it all worthwhile. The two-sail installation is delivering the largest fuel saving of any efficiency technology NAPA has measured. We talk figures of Rotor Sails being effective 80% of sailing time, 460kW average propulsion boost and 1.5MW peaking for 10% of time. The fact that NAPA has not only proven this eco-efficiency technology, but also boosted Norsepower’s enterprise value through orders and investment really shows the power of big data when applied correctly.”
Victoria Stulgis, Senior Associate, Carbon War Room commented:
“It is great to see Norsepower, Bore and NAPA collaborating to pilot this technology and conduct rigorous data analysis. These first movers are key to demonstrating that efficiency technologies such as wind have proven savings, which can unlock new sources of investment for Flettner rotors and other technologies that can deliver significant efficiency gains.”
The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor – a spinning cylinder that uses the Magnus effect to harness wind power to propel a ship. When the wind conditions are favourable, Norsepower Rotor Sails allow the main engines to be throttled back, saving fuel and reducing emissions while providing the power needed to maintain speed and voyage time. Rotor sails can be used with new vessels or can be retrofitted on existing ships without off-hire costs.
