Vale has been studying for the past few years the potential of wind-assisted propulsion for its vessels. They deployed the first test of the rotor sail technology in 2021 aboard the 325,000 dwt Sea Zhoushan owned by Pan Ocean Ship Management. The vessel was also fitted with five rotor sails which in that installation were built by Norsepower.
Earlier this year, Mitsui O.S.K. Lines announced plans to fit two rotor sails aboard an existing 200,000 dwt bulker. The installation is expected in the first half of 2024 on the vessel which also operates under charter to Vale. MOL and Vale have been studying rotor sail installations in a joint project that started in November 2021.
The new installation project involves SDARI (Shanghai Ship Design and Research Institute) and Lloyd’s Register as the classification society for the Sohar Max. Both organizations will work with Anemoi on the designs for the installation. Anemoi highlights that it has also established its supply chain in China partnering with CSSC Chengxi (China State Shipbuilding Corporation), Lianyungang Zhongfu Lianzhong Composite Material Group Co., CRRC Corporation, and SaierNico Electric & Automation. Anemoi will also support the installation on the Valemax vessel with a full array of technical services both pre- and post- delivery including the vessel integration design, support with plan approval, project management and onsite supervision, onboard training, and after-sales services.
Bulkers have been among the first vessels to deploy rotors and other forms of wind-assisted propulsion. Anemoi in June 2023 completed the installation of three rotors on a Tufton-owned bulker TR Lady (82,000 dwt). The vessel operates under charter to Cargill, another large charter of dry bulk carriers.
Other projects have installed the first rotors on large crude oil tankers. Anemoi also recently reported it was launching a study to explore installing rotors of large gas carriers.
