What’s more, this brings Maersk Minder in line with the International Maritime Organisation’s (IMO) recent Tier III emissions standards, even though they are only recommended for vessels built after 2021.
Protecting Marine Wildlife
The final major upgrade was the installation of a Ballast Water Treatment System (BWTS), designed to remove biological organisms from ballast water and prevent accidentally carrying and introducing aquatic invasive species into new waters. This particular BWTS uses a two-step process, first filtering the ballast water through a miniscule 20µ filter (i.e. twenty hundredths of a millimetre), then using UV light to eradicate any remaining hitchhiking aquatic lifeforms including bacteria, microbes, small invertebrates, eggs, cysts and larvae of various species. This cleansing process fulfils yet another IMO requirement and is critical to protecting marine ecosystems, by preventing the spread of invasive species that can out-compete their native counterparts.
