A new analysis takes a look at what the authors say is the environmental impact of the first - ever tumble of a new kind of marine fuel oil . The fuel was develop in response to regulations intended to lour sulfur emanation from thedirty shipping industrybut is leaven more environmental question as it ’s more wide adopted .
The study , put out Tuesday in Marine Pollution Bulletin , looks into fuel spilled during the clank of the bulk carrier MV Wakashio , which ran aground on a coral reef off the Mauritanian coast in July of 2020 . About a calendar month after the collapse , the Wakashio beganleaking fossil oil from crack in its hull . Satellite imagesshoweddark plumes of fuel ballooning out into the quartz glass blue Mauritanian coastline , which is home to a blanket variety of marine lifetime living on its coral reefs and in mangrove forest . Two weeks after the crash , the government declared a “ state of environmental emergency . ”
Since the clangour , there has been heavy speculation that the Wakashio , which had 4,000 tons of fuel aboard , was carrying a new type of fuel that ’s causing business concern among the environmental community . The government activity of Mauritus’smurky responseto the catastrophe include no analyses of the type of oil spill , which fire more surmisal .

The new study confirms that a sample of residue from the coastline taken 5 miles ( 8 km ) from the wrecked ship was fuel from the ship and that it was the newfangled type of low - sulfur fuel . “ Since the foundation of the Wakashio on a coral reef , there has been much guess in the media about what petroleum was spill , including headlines about so - called ‘ Frankenstein fuels ’ , so we require to obtain a sample distribution for inquiry and depth psychology , ” the study ’s booster cable source , Alan Scarlett , a inquiry associate at Curtin University ’s School of Earth and Planetary Sciences , said in anews release .
While it may go like a cinematic exaggeration , “ Frankenstein fuel ” are a growing business concern among those keeping an eye on the shipping industry ’s environmental impact . The phrase was coined as a derogatory term to refer to what ’s known as Very Low Sulfur Fuel Oil , or VLSFOs , a comparatively raw type of fuel blend that ’s derive swelling in ship across the domain .
In January of 2020 , the International Maritime Organization ( IMO ) establish new regulations that required shipping companies tosubstantially low the amount of atomic number 16 in their fuels , to assay and make out merchant marine ’s whopping contribution to air defilement around the world . The industriousness began to quickly favour VLSFOs , thanks in large part to theirlower price pointcompared to other options . VLSFOs , as the name suggest , have far less atomic number 16 than the fuel traditionally used in merchant marine , and thus it fits the IMO ’s new guidepost .
But since they ’re such a new form of fuel , VLSFOs have raised a whole host of other chemic questions — and may help the shipping diligence cut down on sulfur emissions while up other harmful side effects . The Clean Arctic Alliance , a coalition of nonprofits that includes Greenpeace , Friends of the Earth , and the World Wildlife Foundation , hassounded the alarmthat heavy manipulation of VLSFOs could make black carbon emission from the cargo ships sphere even more pronounced . ( dark C , also known as unmixed quondam soot , is a greenhouse gun that expert say is improbably prejudicious to sensitive environments — specially the Arctic — over the myopic term . )
The conversation around VLSFOs reached a top dog last August when the wreck of the Wakashio began leaking in Mauritius , and the young subject provides some much - need answer . First , some preliminary good news show about this particular spill : in the sample of VLSFO collect from the ship ’s shipwreck , researchers found low stratum of toxins dangerous to maritime mammals than are usually present in traditional cargo ships fuels with gamey concentrations of sulfur . Thus , “ the impacts on marine organisms from picture to toxic compounds in the oil may be less severe than with previous spills that involved older types of marine fuel oil , ” Scarlett said .
But because VLSFOs are so raw , Scarlett caution that this sampling could n’t paint a whole picture of the entire fuel class . “ When we analyze several other Low Sulfur Fuel Oils , we notice some contained high concentrations of toxic components than the oil discharged in the Mauritius spillway , so more inquiry will be involve before we can conclude that all the oil types within this new course of instruction pose less of a threat to marine ecosystems than intemperate fuel oil colour , ” he said .
Ultimately , it ’s all important to explore the shock of this fuel on marine environments as well as air defilement , as more and more ships utilize VLSFOs in accord with the raw standards .
“ unluckily , oil wasteweir from ships carry on to be a frequent occurrence , so it is potential we will see further spills involving Very Low Sulfur Fuel Oils , ” Scarlett suppose .
