Sails on ships aren’t anything new. Heck, we’ve been following this “new” technology on cargo ships since 2005. It’s time for our almost annual check-in on how modern ships are using an old tech solution to improve their efficiency. Here’s some additional context for you:
It’s been neat seeing this develop over the last 15 years! The hybrid model is working out well and more companies are embracing it.
At the most recognisable end of the wind-assist spectrum are innovations in soft sail systems. The increasing sophistication of automation and route optimisation systems have revived interest in seafaring’s original power source, and there are now a growing number of examples of larger vessels using smart soft sails alongside auxiliary propulsion systems. In one notable development, French naval architect VPLP recently unveiled a design for a 121 metre long roll-on/roll-off (RORO) vessel that will be used to transport components of the Ariane 6 rocket from Europe to Guiana. The ship’s main propulsion system (a dual fuel LNG MDO engine) will be assisted by four Oceanwings; fully automated wing-sails which are each supported by a 30m high mast and measuring a total of 363 square meters.
It’s that time of year when people buy objects for others because of social obligations or religious practices. When purchasing goods we obviously need to think about the story behind the things being bought (who made it, where it comes from, etc.). If you’re buying stuff online then you should also think about shipping methods beyond the quickest. It turns out online shopping can be the greener option as long as you don’t use the fastest shipping option. Of course, like many environmental issues this one can also be solved by not buying useless stuff.
A 2013 study from MIT’s Center for Transportation and Logistics calculated that the carbon footprint of a traditional shopper purchasing a toy in a store is higher than that of someone who buys the same thing online with regular shipping (more about that later).
That’s because parcel carriers use a more efficient delivery system than you driving to the mall, and the carbon footprint of a website is smaller than that of a brick-and-mortar store.
The shipping industry recently agreed to care about the environment and this led the Guardian to examine how the industry will change. Here at Things Are Good we’ve been keeping an eye on old-school propulsion used on ships since 2005 and one difference now from over a decade ago is the efficiency of hybrid systems. Mixing solar, sails, and other kinds of enhancements with industrial shipping is being explored by all kinds of companies now. In another decade news that ships are more efficient than ever before will likely be standard news – stay tuned for 2028! In the meantime we can envisage what ships will look like and how they’ll reduce the carbon footprint of the shipping industry.
But much could be done more quickly by retrofitting existing ships with technology to cut their fuel use and hence emissions, according to the ITF. Here are just four:
Fitting ships’ bows with a bulbous extension below the water line reduces drag enough to cut emissions 2-7%;
A technique known as air lubrication, which pumps compressed air below the hull to create a carpet of bubbles, also reduces drag and can cut emissions by a further 3%;
Replacing one propeller with two rotating in opposite directions recovers slipstream energy and can make efficiency gains of 8-15%,
Cleaning the hull and painting it with a low-friction coating can deliver gains of up to 5%.
When climate conferences occur and parties sign on to legal agreements like the Paris Agreement some industries are excluded. Historically aviation and shipping have been left out from many climate change agreements which has resulted in both industries being behind the times, inefficient, and down right bad for the planet. Already, climate change is harming coastal nations and these coastal nations usually favour shipping. The impact of increasing water levels, storm surges, and more has led to those shipping-friendly nations to better regulate international shipping practices.
The result is a deal that shipping industry will finally address their greenhouse gas emissions by reducing their emissions by 50% by 2050 compared to 2008 levels.
Mr Paul added: “This is history in the making… if a country like the Marshall Islands, a country that is very vulnerable to climate change, and particularly depends on international shipping, can endorse this deal, there is no credible excuse for anybody else to hold back.”
The UK’s shipping minister, Nusrat Ghani, described the agreement as ” a watershed moment with the industry showing it is willing to play its part in protecting the planet”.
Kjell Inge Røkke made billions from running a shipping company and now he wants to give back to the very thing that made him wealth – the high seas. He has committed to giving away most of his fortune to better the world, and he just announced his donation to WWF Norway. His donation is specifically going to a research vessel that will provide scientists a great way to research the oceans. What’s more is that the same ship will be able to remove 5 tonnes of plastic from the ocean everyday!
Røkke, a former fisherman, said the oceans “have provided significant value for society” and directly to him and his family.
“However,” he noted, “the oceans are also under greater pressure than ever before from overfishing, coastal pollution, habitat destruction, climate change and ocean acidification, and one of the most pressing challenges of all, plasticization of the ocean. The need for knowledge and solutions is pressing.”
“The REV will be a platform for gathering knowledge,” Røkke told Business Insider. “I would like to welcome researchers, environmental groups, and other institutions on board, to acquire new skills to evolve innovative solutions to address challenges and opportunities connected to the seas.”
