The world's first wind powered oil tanker completed the test

After a one-year test period, Maersk pelican, the world's first oil product ship to install wind power energy technology, has achieved a remarkable result of reducing fuel consumption by 8.2% after installing the norsepower windmill The Maersk pelican is a 109647 DWT LR2 product tanker owned by Maersk oil tanker, and the largest ship in the world to install the spiral sail. In August last year, two Flettner windmills from norsepower, Finland, were installed on the Maersk Pelican. The test period starts on September 1, 2018 and ends on September 1, 2019 Recently, norsepower confirmed that in the 12-month test, the rotary sail saved 8.2% of the fuel consumption of Maersk pelican, which is equivalent to about 1400 tons of carbon dioxide According to the explanation of norsepower, the cost saved by the cyclone sail is confirmed by comparing the detailed performance information data with the baseline level obtained from the comprehensive measurement and calculation analysis of the ship before the installation of the cyclone sail.

Norsepower said that the independent experts of LR ship performance team have analyzed and verified the performance data during the project to ensure fair evaluation, and the technical and operational insights of performance research will also be released "During the 1-year test period of Maersk pelican, the crew and operators gave a positive evaluation on the availability, safety and performance of the cyclone sail in any case," said Tommy Thomassen, chief technical officer of Maersk "We believe that wind energy technology can bring us a real breakthrough in reducing carbon dioxide emissions and help us achieve the goal of reducing carbon dioxide emissions by 30% by 2021," Thomas Sen said It is understood that the project is supported by Maersk, norsepower, the British Energy Technology Institute (ETI) and shell shipping company, funded by the British Energy Technology Institute and sponsored by Maersk and norsepower. Shell will act as project coordinator, providing operational and terminal port consulting services to the project team, and Maersk will provide technical and operational analysis norsepower windmill has been applied to three different ship types.

It is understood that norsepower windmill is designed by German engineer Anton Flettner. Each windmill is made of the latest intelligent light composite sandwich material, which will provide a simple but solid high-tech solution. When the wind conditions are met, the main engine can adjust the throttle to decelerate, providing net fuel cost and emission cost savings, at the same time, it will not affect the heading plan norsepower's Flettner rotary sail is a large-scale cylindrical mechanical sail. Its rotation produces a pressure difference (Magnus effect), which pushes the ship forward. This technology provides auxiliary wind propulsion for ships, so as to optimize energy efficiency and reduce energy consumption In theory, norsepower's Flettner sail can be used for oil tankers, bulk carriers, large ro ro passenger ships and passenger ships, and can be used for global navigation. Including "Maersk Pelican", norsepower's rotary sail is currently installed on three ships, including "estraden", a RORO cargo ship operated between the UK and Belgium and "Viking grace", a LNG powered cruise ship operated by Viking line in the Baltic Sea camp Tuomas riski, CEO of norsepower, previously introduced that as early as 2014, norsepower had applied the produced rotary sail to a 9700 DWT ro ro ro ship "estraden" owned by bore, a Finnish shipowner.

The two smaller rotary sails installed on the ship were proved to reduce fuel oil consumption by about 6.1%, which is equivalent to saving 400 tons of fuel per year Feed oil. According to the data provided by estraden, norsepower expects fuel oil savings of up to 20% for a single vessel under the combined effect of favorable air flow, large enough rotary sail and proper speed In April 2018, norsepower also applied the spinning sail technology to a LNG powered cruise ship "vikinggrace", making it the first LNG / wind powered hybrid cruise ship in the world, and one of the most environmentally friendly cruise ships at present. It is estimated that due to the intervention of rotary sail technology, the carbon dioxide emission of Viking grace will be reduced by about 900 tons / year, which is equivalent to an average annual saving of about 300 tons of LNG According to Tuomas riski, CEO of norsepower, the three ships use norsepower's rotary sail for daily commercial operation. Three cases represent three completely different ship types and operation conditions, showing a wide range of opportunities to utilize wind energy through the rotary sail Earlier this year, norsepower's rotary sail has obtained the type approval design certificate of auxiliary wind propulsion system for the first commercial ship issued by dnvgl. Obtaining this certificate means that ships operating through norsepower's rotary sail power plant are technically able to navigate safely "under all operating and environmental conditions".
