The CEO of Paris-based OceanWings, Emmanuel Schalit, explains to ship.energy why his company’s ‘passive’ wind-assisted propulsion systems (WAPS) are suited to the gas carrier segment, and how the failure to adopt the International Maritime Organization (IMO) Net Zero Framework last month makes wind propulsion even more important. OceanWings has recently worked on a case study with France LNG Shipping regarding the retrofit of wind-assisted propulsion system (WAPS) technology throughout its gas carrier fleet. What are some of the main challenges – technical or financial – that are specific to these kinds of vessels compared with other vessel segments, such as […]

UK-based Anemoi Marine Technologies has installed five of its 35 metre-tall rotor sails on NS United Kaiun Kaisha’s (NSU) 400,000 DWT ore carrier NSU TUBARAO. In a statement sent to ship.energy today (12 November), Anemoi said that the vessel, which is chartered by the mining company Vale International, is expected to reduce its fuel consumption by 6-12% annually through using the wind-assisted propulsion system. The NSU TUBARAO is the fourth Vale-chartered very large ore carrier (VLOC) to be retrofitted with Anemoi rotor sails. The rotor sail installation on the five-year-old vessel was completed during scheduled drydocking in October at the […]

Wind-assisted ship propulsion company (WAPS) BAR Technologies has announced that its P-Wind methodology – the approach used to quantify the power delivered by its WindWings installations – has been independently reviewed and approved by Lloyd’s Register. In a statement issued today (11 November), UK-based BAR Technologies said the confirmation means its computational fluid dynamics (CFD)-based model now aligns fully with International Maritime Organization (IMO) guidance (MEPC.1/Circ.896) and ITTC verification standards. ‘This approval from Lloyd’s Register moves the conversation from promise to proof,’ said John Cooper, CEO of BAR Technologies. ‘It shows that our modelling delivers decision-grade numbers trusted by class, and […]
