Although the Nanol and Norsepower case stud- ies sound similar, NAPA's advanced statistical analysis specialists have delivered very different studies to verify each technology. Each started with measurement before the application of the technology to get an accurate baseline of consump- tion, performance and operational pro•le. For Nanol, the fuel saving under analysis was likely to be small and only within Nanol's optimal performance range for engine load. The analysis developed, therefore, took into account fuel calori•c value, operating conditions and typical engine load range over several months to provide a highly accurate view of the impact when the additive was present in the vessel's lube oil. Norsepower's technology provides an assist to vessel propulsion using the power of the wind. It was vital to take into consideration any resistance factors that were changing the power output required by the engine without the propul- sion assist. A less advanced process could have been easily led astray by weather conditions that changed the required power output. NAPA's system incorporated weather data and measured onboard data to take into account factors such as wave and wind resistance, propeller ef•ciency and the effect of different drafts and tide conditions. The testing design also incorporated randomized trialling to ensure that the results were statistically signi•cant. Using this ensured that the saving was veri•ably attributable to the Rotor Sail. Each veri•cation project has its own speci•c challenges, whether posed by the vessel's route, the data or the technol- ogy itself. The one thing that they all have in common is a commitment to accurate veri•cation with proven, third- party results that are crucial to commercial success. Recipe for Success The certainty that a technology's output is in line with the promises made provides investment clarity and reduces the risk associated with innovation. Despite the current market situation, new technologies are being unveiled on a regular basis, designed to transform vessel operations, crew produc- tivity or the environmental impact of a ship. But "challeng- ing the status quo" and "disrupting the market" isn't easy. The decision to change can be dif•cult. Business as usual has a known outcome for all stakeholders; following a dif- ferent route often doesn't. The ability to communicate cred- ibly and accurately the potential of a technology to clients and investors alike is the core of third-party veri•cation. For these nascent businesses, real-time monitoring and analysis can provide a very real chance to differentiate their claims and establish themselves as a respected and proven manu- facturer. ST partnership with the vessel's char- terer, Transfennica, commissioned NAPA to conduct a study to verify that Nanol's additive could make a signi•cant difference to the fuel consumption of a vessel. Advanced statistical analysis by NAPA veri•ed that Nanol's prod- uct delivered a 2 percent reduction in fuel consumption on MV Seagard, an operational Ro-Ro cargo vessel. This has led to a promising relationship between Nanol and Trans- fennica, with Transfennica continuing to use Nanol on the vessel, as well as considering extending its use to other ves- sels in its Œeet. The fact that Nanol's claims were supportable and backed up by impartial and clear data analysis has also secured Na- nol the opportunity to present to more than 100 venture capitalists at an exclusive event for technology start-ups to support its future growth. Creating the Winds of Change Norsepower has also proven its technology through third-party veri•cation and reaped the commercial bene•ts. When the wind conditions are favorable, Norsepower Rotor Sails allow the main engines to be throttled back, saving fuel and reducing emissions while providing the power needed to maintain speed levels and retain voyage time. Early in 2016, NAPA was able to con•rm this fuel saving, verifying a fuel consumption reduction of 2.5 percent from a single Ro- tor Sail installation on Finnish shipowner Bore's 9,700-dwt Ro-Ro carrier Estraden. As a result of the proven effectiveness of this technol- ogy, Bore installed a second Rotor Sail on the same vessel; the •rst commercial order of Norsepower's technology. After this second installation, NAPA's software was able to con- •rm that the two Rotor Sails are now delivering fuel savings of 6.1 percent, more than doubling previous savings. This data analysis and veri•cation has been fundamental to Norsepower's business development by proving the effec- tiveness and applicability of its technology on operational commercial vessels. A syndicate led by Power Fund III, a clean tech venture fund managed by VNT Management, has now invested €3 million to support Norsepower's growth and market expansion. Tuomas Riski, Norsepower's CEO, has been vocal in support of the importance of third-party veri•cation, publicly stating how vital it is to have objective data to substantiate the achievable fuel savings, and how instrumental this has been in supporting business growth. In addition to the expanded market potential offered by the •rst commercial purchase, this evidence has also helped Norsepower increase its enterprise value and protect the ongoing commercial activities of the company. Process and Implementation Each solution available to the market presents its own speci•c measurable data, and the varying conditions faced by each vessel present unique variables that need to be taken into account or •ltered. Internationally trading ves- sels are now very complicated; the various power demands, fuel consumption and even the energy conveyed by the fuel can vary after each bunkering. Achieving an accurate and clear understanding of the impact of one speci•c technol- Jouni Salo is the product manager of shipping solu- tions at NAPA.
