Final night time, the Carnival Magic dumped a considerable amount of poisonous emissions residue collected from the vessel’s so referred to as “Superior Air High quality System” into the water in Grand Turk because it was getting ready to proceed on its cruise within the Caribbean. A number of passengers aboard the Carnival cruise ship, who had been apparently confused with what they noticed, mistakenly referred to as the scrubber discharge a “big oil slick” or an “oil spill.”
Carnival stated in a press launch, printed by the favored Cruise Radio and the Cruise Hive cruise fan websites, that the unintended discharge was the results of what it’s calling a “soot discharge” from the ship’s “Exhaust Gasoline Management Programs (EGCS).”
Carnival’s EGCS are generally referred to as “scrubbers” that are used to try to take away non-combustible particles equivalent to soot, incompletely burned oil, and ash, from its emission stacks. A scrubber works by spraying alkaline water (normally seawater) into the vessel’s exhaust stacks, which is designed to scale back carbon, sulfur oxide (SOx) emissions, and non-combustible particles from bunker gasoline from the ship’s engine exhaust gases. Carnival has determined that it’s cheaper to make use of such programs relatively than buy dearer low sulfur gasoline.
Carnival closely promotes using scrubbers all through its fleet together with ships operated by its quite a few manufacturers. It euphemistically calls scubbers “A Clean Solution for Air and Water.“
The pollution which scrubbers take away from the air are referred to as “scrubber sludge” or just “sludge,” that are correct descriptions of the poisonous mixture of metals, equivalent to lead, nickel and zinc, in addition to hydrocarbons, sulfur, and nitrogen compounds. Within the “open loop” programs generally utilized by Carnival, the poisonous and acidic sludge is then dumped again into the ocean.

Many individuals name scrubbers “emissions cheat” programs that are designed to keep away from the delivery business having to purchase cleaner, dearer gasoline. The Guardian newspaper referred to as them an “environmental dodge.” In probably the most used system, often called “open loop,” the waste water is discharged into the ocean. “Scrubbers successfully flip air air pollution into water air pollution,” says Kendra Ulrich, of environmental group Stand.earth.
This isn’t the primary time that we now have seen scrubber sludge dumped from a Carnival Company-owned cruise ship. In August of 2018, Princess Cruises’ Star Princess cruise ship discharged sludge from its exhaust system scrubbers within the port of Ketchikan, Alaska in accordance with the town of Ketchikan, as initially reported by KRBD Community Radio. KRBD additionally reported that the town obtained complaints by the general public of an earlier comparable discharge from the Golden Princess whereas in Ketchikan. We wrote about the dumping of scrubber sludge from the Carnival Company-owned ship on the time.
Princess Cruises responded to an article in Travel Weekly in regards to the disgusting incident in Alaska by claiming that what’s proven within the images was simply “sea foam discolored by pure microorganisms equivalent to algae within the seawater.”
When Carnival Company and its subsidiaries had been beneath probation for felony air pollution crimes from 2016 to 2021, the Court docket Appointed Monitor submitted a number of reviews to the senior federal decide that Carnival was routinely violating probation by its discharges of wash water to the ocean from its “Superior Air High quality Programs.”
The irony is that though this incident was apparently inadvertent, Carnival routinely dumps this nasty sludge into the water around the globe. It’s my impression that most individuals who cruise should not conscious of those environmental cheat units utilized by Carnival (and different manufacturers) to proceed to burn cheaper, excessive sulfur fuels, nor are they conscious that cruise ships routinely discharge poisonous waste water residue from scrubbers because the ships sail. What occurred yesterday on the Carnival Magic was clearly an accident to the extent that a lot sludge was dumped without delay within the water at port versus being slowly discharged at sea and away from shore the place it might not be noticed so readily.
.Within the Journey Weekly article cited above, the journal reported that cruise ship scrubbers “produce a shocking quantity of waste: A mean seven-day cruise on a giant ship can yield two to 5 tons of scrubber sludge, stated Brian Salerno, senior vp for maritime coverage at CLIA.”
There’s a noticeable distinction in slowly emptying the scrubber sludge tanks over the course of every week lengthy cruise within the Caribbean earlier than returning to port in Florida and inadvertently dumping 5 tons of sludge unexpectedly at a port earlier than a boatload of friends with iPhones.
