Tanker Ships Set Sail for Greener Future with Wind-Powered Technology
Tyler Durden

Ever seen a massive tanker ship...with wind sails? You might soon.

That's because the Sohar Max, a 400,000-deadweight-ton vessel, was just retrofitted with five 35-meter rotor sails at China's COSCO Zhoushan shipyard, according to Bloomberg. The purpose is to reduce fuel use by 6% and cut annual carbon emissions by 3,000 tons. 

Bloomberg reported that the shipping industry already faces regulatory pressure to reduce emissions. Rotor sails remain uncommon, and the adoption of wind technologies hinges on cost savings. Their appeal may grow as shippers transition from oil to pricier, cleaner marine fuels, the report says.

Nick Contopoulos, chief production and partnerships officer at Anemoi Marine Technologies, said: “There’s definitely an uptick in the adoption of wind propulsion and not just rotor sails, but other technologies too.”

California, for example, just expanded its emissions regulations at its port, DNV wrote last month. Starting January 1, 2025, California will expand its emissions regulations for vessels at ports.

Initially introduced in 2007 for container, passenger, and refrigerated-cargo ships, the rules now include Ro-Ro and tanker vessels. Ships must control emissions of NOx, PM 2.5, and reactive organic gases by connecting to onshore power, using approved exhaust capture systems, paying into a remediation fund, or adopting alternative fuels.

Tanker vessels face phased compliance, starting with the ports of Los Angeles and Long Beach in 2025 and all California terminals by 2027.

Most other emissions standards are "primarily governed by the International Maritime Organization (IMO)" and "require ships operating in designated Emission Control Areas (ECAs) to meet stricter sulfur fuel limits and engine emission standards".

our method: pseudonymous speech...
Anonymity is a shield from the tyranny of the majority. it thus exemplifies the purpose behind the bill of rights, and of the first amendment in particular: to protect unpopular individuals from retaliation-- and their ideas from suppression-- at the hand of an intolerant society.

...responsibly used.

The right to remain anonymous may be abused when it shields fraudulent conduct. but political speech by its nature will sometimes have unpalatable consequences, and, in general, our society accords greater weight to the value of free speech than to the dangers of its misuse.

Though often maligned (typically by those frustrated by an inability to engage in ad hominem attacks) anonymous speech has a long and storied history in the united states. used by the likes of mark twain (aka samuel langhorne clemens) to criticize common ignorance, and perhaps most famously by alexander hamilton, james madison and john jay (aka publius) to write the federalist papers, we think ourselves in good company in using one or another nom de plume. particularly in light of an emerging trend against vocalizing public dissent in the united states, we believe in the critical importance of anonymity and its role in dissident speech. like the economist magazine, we also believe that keeping authorship anonymous moves the focus of discussion to the content of speech and away from the speaker- as it should be. we believe not only that you should be comfortable with anonymous speech in such an environment, but that you should be suspicious of any speech that isn't.
