Classification society ABS has been selected by SEACOR Marine to class the first hybrid offshore support vessel (OSV) in the Gulf of Mexico (GOM) with the BATTERY-Li notation. 

The SEACOR Maya OSV, currently operated by Mantenimiento Express Maritimo (MEXMAR) a SEACOR Marine’s joint venture in Mexico, will be upgraded to use lithium battery power with modifications expected to be completed in May 2018.

“ABS recognises the economic and environmental benefits of hybrid powered vessels to reduce fuel consumption and emissions in the marine and offshore industries,” said ABS Director for Offshore Support Vessels, Dr. Wei Huang.

“This milestone reinforces our safety mission and promotes development of alternative power applications and energy storage systems that optimise efficiencies.”

Additionally, SEACOR has engaged ABS to provide the optional BATTERY-Li notation on three OSVs operated by MEXMAR which are planned to upgrade to a similar battery system.

The conversion to hybrid power for SEACOR Azteca, SEACOR Warrior and SEACOR Viking is expected to be completed in July 2018.

“The hybrid power solution on the SEACOR Maya has the potential to significantly reduce fuel consumption by as much as 20%,” said SEACOR Manager of Engineering, Tim Clerc.

“Integrating new technologies is complex. To help SEACOR realise the benefit of using cutting-edge hybrid power, we partnered with ABS, to class the lithium battery system, to help validate its reliability.

“The operational savings gained from a hybrid power solution will also reduce emissions and facilitate our compliance to strict environmental regulations.”

Exclusive: Anemoi lays out financial and environmental benefits of Rotor Sails

UK-based Anemoi shared with Manifold Times financial benefits from reduced bunker fuel consumption when utilising wind-propulsion technology and its long-term environmental benefits.





Exclusive: Anemoi lays out financial and environmental benefits of Rotor Sails

Anemoi Marine Technologies, a UK-based Rotor Sail developer, wrote an exclusive editorial contribution for Singapore-based bunkering publication Manifold Times exploring the financial benefits from reduced bunker fuel consumption when utilising wind-propulsion technology while also highlighting the long-term environmental benefits of the technology for ship owners: 

As the global shipping industry ramps up decarbonisation efforts, modern cargo vessels are striving for energy efficiency, guided by the International Maritime Organization's (IMO) regulations.  The IMO’s 80th meeting of its Marine Environmental Protection Committee (MEPC 80), which took place in July 2023, spotlighted vessel efficiency, emphasizing a review of energy efficiency design requirements, including the Carbon Intensity Indicator (CII) and the Energy Efficiency Existing Ship Index (EEXI).

In pursuit of the IMO's net-zero target of 2050, ship owners are embracing low and zero-carbon technologies. Among these, innovative propulsion options like Flettner Rotors, or Rotor Sails, are gaining traction. These advanced sails, inspired by history but technologically superior, offer auxiliary propulsion to vessels to enable them to maintain their speed but with reduced fuel usage, which can in turn significantly reduce carbon emissions.

Rotor Sails are particularly popular for their retrofitting potential, allowing easy installation on existing vessels in port or dry dock.  With wind power abundant on many trade routes, ship owners are embracing these modern solutions to drive efficiency and cut emissions.


Rotor Sails are genius in their ingenuity. They harness the “Magnus Effect”, rotating within airflow to produce forward thrust perpendicular to the wind. This additional thrust can enhance speed or reduce engine power, dramatically cutting fuel consumption and emissions. Versatile and simple to install, they are suitable for various vessel types. Each sail can be swiftly fitted, even during dry dock or while berthed, making them ideal for rapid retrofits. Moreover, they are portable assets, and can be transferred between ships as required. With their uncomplicated design and swift installation, Rotor Sails offer a rapid and efficient solution for reducing emissions and enhancing efficiency in the maritime sector.

Rotor Sail placement and design on vessels must carefully consider safety and efficiency, ensuring no hindrance to cargo handling. Anemoi Marine Technologies, a leading developer based in the United Kingdom and with a world-class production facility in China, retrofitted three 24-m Rotor Sails on the Kamsarmax bulk carrier TR Lady in June 2023 at Chengxi Shipyard in China. Despite the challenge larger bulkers face in meeting efficiency targets, Rotor Sail technology is ideal due to their ample deck space and predictable wind patterns.

TR Lady's trial voyage from China to Australia yielded positive results and annual savings of 10% in fuel consumption and emissions are expected. The sails, which are installed on Anemoi’s transverse rail deployment system, can be moved on the deck when berthed for cargo operations.

Anemoi's Chief Executive Officer, Kim Diederichsen, highlighted the effectiveness and cost efficiency of the technology in reducing emissions: “The installation of Rotor Sails on TR Lady and the results we have seen so far show how effective Rotor Sails are when it comes to reducing the fuel consumption and emissions of a vessel. Rotor Sails are a visible, viable and cost-effective decarbonisation technology.”

Diederichsen went on to say: “Our background equipped us with the knowledge of how to best adapt the technology for complex vessel operations. As a result, we developed a range of Rotor Sails with variable heights and, most uniquely, a range of deployment systems and mounting arrangements. This includes a standard fixed mounting; a folding deployment, which enables the cylinders to be lowered from vertical to enable the vessel to pass under low bridges and avoid impact to cargo loading and unloading; and finally our patented rail system that was used on TR Lady.”

Their technology, adapted for complex vessel operations, includes variable heights and deployment systems like folding and patented rail systems, ensuring adaptability and minimal impact on cargo operations.

Anemoi developed a Fuel Saving Assessment Model (FSAM) to accurately predict fuel and emissions savings. FSAM utilizes Rotor Sail performance, vessel data, route, and wind conditions to simulate historic voyages over five years, ensuring fair and transparent results accounting for additional drag and generator usage.

Forward Thinking

Anemoi already has a number of projects underway with some of the industry’s biggest names, including Vale and Berge Bulk to install Rotor Sails onboard vessels over the coming months and, in February, it received funding from the UK’s Clean Maritime Demonstration Competition to develop a new diameter of Rotor Sail and innovative drive system. Buoyed by its success on bulk carriers, Anemoi has also signed a deal with Hudong-Zhonghua Shipbuilding Group to develop Rotor Sail designs specifically for LNG vessels.

As per the UK’s Clean Maritime Plan, the wind propulsion technology market, including Rotor Sails, is expected to soar to GBP 2 billion (USD 2.5 billion) annually by 2050, a substantial rise from the projected GBP 300 million in the 2020s.

This growth is directly tied to the credibility of Rotor Sails as a decarbonisation technology.  As alternative fuels and other eco-friendly innovations become market-ready, auxiliary wind propulsion methods can be used in tandem to garner even more environmental benefits for the shipping sector.
