Rotor Sails News

Brazilian mining firm Vale will install five Rotor Sails from Anemoi Marine Technologies Ltd (“Anemoi”), a supplier of wind-assisted propulsion technology for commercial vessels, onboard a 400,000 dwt Valemax, the world’s largest ore carrier. The vessel is owned by Omani shipowner, Asyad.Five 35-meter-tall, 5-meter-diameter cylindrical sails will be installed on the Sohar Max VLOC. The Rotor Sails will be installed on Anemoi’s folding deployment system, whereby the sails can be folded from vertical to mitigate impact on air draft and cargo handling operations.

CLdN announced one of its RoRo car carrier vessels is ready for its return to service after being fitted with a rotor sail wind propulsion system.The Luxembourg based company is the latest in a string of ship owners and operators to have turned to wind propulsion systems as a means to reduce fuel burn and emissions amid its journey to improve operational efficiency and its environmental footprint.Now fitted with two 35mx5m rotor sails, Delphine is the first vessel in the CLdN fleet to be fitted with the system and will return to service from Zeebrugge…

The Liberian Registry has awarded an Approval in Principle (AIP) to Anemoi Marine Technologies for their Rotor Sail systems.Anemoi’s Rotor Sails are available with three deployment options - fixed to the deck, a folding type, and on rails that can be moved along or across the deck.According to a press statement released Tuesday, the folding and rail systems were validated on a Newcastlemax bulk carrier design from SDARI and issued an AIP by Lloyd’s Register.The Liberian Registry conducted a technical review of the documentation…

Based in the UK, GT Green Technologies said it secured grant funding from its Department of Transport following this year’s Clean Maritime Demonstration Competition Round 2 (CDMC2) for the company’s proprietary AirWing propulsion solution, currently in development. Patent-pending, AirWing is designed to help ships reduce emission while retaining a compact size and low-profile stowage functionality to ensure uninhibited loading and unloading of vessel cargo.Available as either a retrofit or newbuild option…

Singapore-based dry bulk owner Berge Bulk has signed a deal with wind-assisted propulsion firm  Anemoi Marine Technologies to supply and fit two vessels in their dry bulk fleet with Anemoi Rotor Sails.Rotor Sails are large mechanical sails that harness the renewable power of the wind to reduce emissions and fuel consumption on commercial ships when driven to spin. Anemoi predicts that the four-rotor system will save Berge Bulk 1200-1500 metric tons of fuel per vessel each year.The first vessel…

Global supplier of wind propulsion, Anemoi Marine, believes Rotor Sails - which are unique, tall cylindrical sails that can be installed on the deck of commercial vessels - offer an immediate and compelling solution for shipowners working to reduce vessel emissions.Anemoi estimates that a VLCC with six Rotor Sails would reduce fuel and emissions by approximately 14.9% (c.1,889 tonnes fuel and c.6,058 tonnes of carbon) per year, based on a Bonny-Ningbo round trip.When considering fuel savings for bulk carriers…

What: Natural Propulsion in Ship DesignWhen: November 16, 2021Where: Webb Institute, Glen Cove, NY (broadcast live)Hosts: Webb Institute, Marin Institute, and Wind Support NYCA new conference on the use of natural propulsion in the global shipping industry will take place in New York on November 16, 2021, hosted by Webb Institute in Glen Cove, NY, and broadcast live.The conference aims to introduce to the audience the design of hybrid merchant ships capable of harnessing free and renewable energies available onboard – wind…

Denmark-headquartered ferry operator Scandlines has opted to install a rotor sail on board a second vessel in its fleet after equipping the hybrid ferry Copenhagen with its first wind auxiliary propulsion unit in 2020.Berlin, a sister vessel to Copenhagen, also operates on the Rostock-Gedser route but, unlike Copenhagen, is flagged by Germany.Scandlines has had more than a year to collect data on how the Norsepower rotor sail works on Copenhagen, and what effect it has on the route.Scandlines’ COO…

TR Lady Shipping Ltd, a portfolio company of Tufton Investment Management Ltd (“Tufton”), signed a contract Anemoi Marine Technologies to supply and fit the bulk carrier TR Lady with three large Rotor Sails and Anemoi’s patented Rail Deployment System, a system designed to allow the Rotor Sails to be moved across the deck to minimize impact on port operations.TR Lady is a CS Marine design 82,000DWT Kamsarmax bulker, built in 2017 by Yangzijiang Shipbuilding Group, and managed by Tufton. TR Lady will be retrofitted with the Rotor Sails during scheduled dry docking of the vessel.

South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) received an approval in principle (AiP) from classification society DNV for the DSME Rotor Sail System for large oil tankers and liquefied natural gas (LNG) carriers.Desigend to provide eco-friendly auxiliary propulsion for ships, a rotor sail system incorporates the installation of cylindrical columns (rotors) on the vessel’s deck to generate additional power to propel the ship by using the force of the wind and column rotation during operation.“In this time of growing pressure to decarbonize…

The technology group Wärtsilä said it has signed a Memorandum of Understanding (MoU) tied to a License and Cooperation agreement with U.K.-based Anemoi Marine Technologies for the future sales and servicing of Rotor Sail solutions to the shipping industry.Rotor Sails, also referred to as Flettner Rotors, are comprised of vertical cylinders which, when driven to rotate, harness the renewable power of the wind to propel ships. These highly efficient mechanical sails capitalize on…
