MIURA's ballast water management system HK is the first in Japanto have obtained USCG type approval for its filtration method with
UV treatment
MIURA CO.,LTD. (Head Office: Matsuyama, Ehime; President & CEO: DaisukeMiyauchi), Japan's leading manufacturer of industrial boilers, on October 28, 2019,became the first manufacturer in Japan*1 to obtain the type approval certificate from theUSCG*2 for its ballast water management system HK that uses the filtration methodwith UV treatment.
The USCG type approval certificate is required for any vessel that enters a U.S. harborby the ballast water treatment regulations of the United States Coast Guard. Ballast
water treatment system manufacturers around the world today seek to obtain this
USCG type approval. Because using the filtration method with UV treatment does notentail the use of harmful substances in the treatment process, it offers the strong pointof producing treated water that does not have an impact on the organisms in the area
where water is discharged. MIURA uses this environmentally friendly method.
Japan has one of the largest maritime business clusters in the world. MIURA's marine
businesses have won praise for the results we achieved over the course of a half century.
Furthermore, we have obtained a certificate that has been expected among those whowanted to use equipment from Japanese manufacturers.
Also, our HK system developed in-house saves
space, conserves energy, and reduces labor needs.
It has been put into operation on more than 750 units
so far, and many customers are putting it to work.
Through our future efforts at manufacturing new
ships with the ballast water management system
HK, and retrofits*3 for existing ships, we will satisfy
the desires of our customers while we prove ourperformance in engineering, installation supports,
and trial cruises for different ship types.
Furthermore, as a company that will contribute tocreating a society that is environmentally friendly
and ways of living that are clean and comfortablethrough our work in the field of the energy, water,▲USCG type approval certificate:and environment, including through its efforts to162.060/23/0

help protect maritime environments around the world, we offer a variety of products inthis vein around the world.
●Target sales number of units:
1,200 units in total (end of fiscal 2020)*1: By MIURA's own research*2: USCG = An abbreviation for the United States Coast Guard*3: Retrofit: Installation of equipment in ships already in service

What is ballast water?
Ballast water is the sea water that a ship takes on board when it is unloaded or the load
it is carrying is light. Taking on an appropriate amount of ballast water in proportion toload weight makes it possible to maintain the propulsion efficiency of the propeller(s) andrudder efficacy, as well as guarantee an appropriate draft line (center of gravity) for safeand efficient navigation.

The ballast water problem
In recent years, there have been reports from around the world about damage toecosystems and economic harm caused by ballast water. Since ballast water basicallyis taken on board at the port of loading and discharged at the port of unloading, if thoseports are in different countries the aquatic organisms in the ballast water will be movingaround the world. Some put the volume at 3 billion tons per year, while others say it is
10 billion tons. The instances in which organisms that do not usually inhabit a particulararea are having an impact because of having been moved like this naturally are leading
more and more people to point out the environmental and economic risks that this is
expected to have in the future.
