DNV GL已向芬兰Norsepower公司研制的旋筒风帆风力推进技术（auxiliary wind propulsion system Rotor Sail Solution）颁发型式认可证书。
Norsepower表示，旋筒风帆装置（Rotor Sail Solution）是首个获得型式认可的商船用风力推进系统。
DNV GL对Norsepower制造的尺寸为30米*5米的旋筒风帆进行了设计评估，并于2019年2月颁发型式认可证书。此前已有两台旋筒风帆安装在马士基LR2油轮Maersk Pelican号上。
Norsepower公司CEO Tuomas Riski表示：“获得型式认可证书对我们非常重要。”
DNV GL公司船级与技术指导主管Geir Dugstad补充说：“我们需要多种燃料和技术来减少航运业带来的环境影响，因此我们很高兴Norsepower公司能邀请我们加入这个极具创造性的风力推进项目。”
DNV GL Certifies Norsepower’s Auxiliary Wind Propulsion Solution
Ship classification society DNV GL has issued a type approval design certificate for Norsepower’s auxiliary wind propulsion system Rotor Sail Solution.
As noted by Norsepower, Rotor Sail Solution is the first auxiliary wind propulsion system onboard a commercial ship to receive the certificate.
The approval was issued by DNV GL in February 2019 after a design assessment of Norsepower’s 30-meter by 5-meter rotor sail, two of which have been installed onboard the Maersk Pelican LR2 tanker.
The certification means that vessels operating Norsepower’s Rotor Sail Solution are technically capable of safely navigating ‘all operational and environmental situations’.
Norsepower’s Rotor Sail Solution has already been installed on three vessels and has achieved over 35,000 hours in operation, saving more than 4,500 tonnes of CO2 in the process. The solution has delivered independently verified fuel savings with potential of up to 20%, according to the company.
“Having a type approval design certificate is very important to us,” Norsepower CEO Tuomas Riski said.
“Clearly, it [the type approval design certificate] provides shipowners, operators, and charterers with a level of assurance when investing in the Rotor Sail Solution, but in the long term, it removes yet another hurdle to the realisation of renewable wind energy propulsion systems at a scale that supports shipping’s transformation to a low carbon transport sector.”
“To help reduce shipping’s environmental impact we will need many different fuel and technology options, which is why we were very pleased that Norsepower asked us to be part of this innovative wind propulsion project,” Geir Dugstad, director of ship classification and technical director at DNV GL, added.
