Carnival Corporation has released the results of an independent, two-year scientific wash-water study, which has concluded that the company’s scrubbers are in compliance with the International Maritime Organization’s 2020 requirements.
The study also concluded that the wash-water samples from scrubbers were below the limits set by several major national and international water quality and land-based water discharge standards.
The study comprised 281 wash-water samples from 53 Carnival Corporation ships equipped with the systems.
The samples were analyzed for 54 parameters by independent laboratories accredited by the International Organization for Standardization (ISO), using standardized EPA methods, said Carnival. The laboratory test data was also independently reviewed, comparing the results with major point source discharge limits and water quality standards.
The study confirmed results from previous studies showing the quality of the water used in the process was far below the IMO monitoring limits for polycyclic aromatic hydrocarbons (PAHs) and the annual limits for nitrates.
Mike Kaczmarek, senior vice president for marine technology for Carnival Corp, said that “we are pleased to see the positive results of this multi-year study, which included in-depth analysis and review from respected independent experts, demonstrating the overall quality of our Advanced Air Quality Systems wash water and further confirming the IMO’s acceptance of these systems for 2020 regulatory compliance,” adding that “based on extensive emissions testing, we know that our Advanced Air Quality Systems in some ways outperform marine gasoil (MGO) in providing cleaner air emissions. And although we have known for a long time that the quality of water being returned to the sea is at a high level, based on our years of development of this data set, it was important to release the findings publicly as the latest scientific evidence showing the actual water quality. This is completely consistent with the commitments we have made to our sustainability goals, and to protecting the ocean environment and the destinations we visit around the world.”
Meanwhile, France-based shipping company CMA CGM has announced that it will be levying low sulphur surcharges for containerized shipments passing through north Europe’s emissions control area (ECA), which covers Scandinavia, Poland and Baltic and onwards to the west coast of South Africa, east coast of South Africa, French West Indies, French Guyana, east coast Central America, Caribbean and Guyana in north Brazil.
Starting from April 1st, shipments to west coast South America, east coast South America, French West Indies, French Guyana, east coast Central America, Caribbean and Guyana that originate from the north Europe ECA will be subject to a surcharge of €13 per TEU. Shipments from Scandinavia, Poland and the Baltic region to these areas will be required to pay a low sulphur surcharge of €26 per TEU. The associated basic freights and other bunker-related surcharges, terminal handling charges (origin and destination), peak season charges and safety and security-related surcharges may also apply.
