The Optimarin Ballast System effectively cleans ballast water, dramatically reducing the threat posed by invasive aquatic species.
About 80 per cent of world trade is transported by ship, according to the International Maritime Organization (IMO). Each year, this results in ships transferring 10 billion metric tons of ballast water between oceans or regions, with 7 000 species transferred every hour.
Ballast water is essential to safe, efficient shipping, providing balance and stability to unladen vessels. It is, however, a means of spreading invasive aquatic species – one of the greatest threats to the world’s oceans.
The Optimarin Ballast System uses filters and UV treatment to kill or inactivate marine organisms, viruses and bacteria in ballast water. No chemicals are used or harmful residual products left behind.
The system features a pressure flow valve for full control of both flow and pressure, as well as a touch screen interface for easy control of operation.
The system was approved in 2009 in accordance with Guideline 8 for the implementation of the International Convention for the Control and Management of Ships’ Ballast Water and Sediments.
In 2016, it became the first ballast water treatment system to be approved by the US Coast Guard.
It also complies with the requirements of the EU’s ATEX Directive on equipment for potentially explosive atmospheres and is approved for use in Zone 1.
The Optimarin Ballast System is highly effective, removing more than 99.9 per cent of certain species of plankton. It requires minimal maintenance and is self-cleaning, with no moving parts.
The system can be installed on both newbuilds and retrofits, and tailored to user needs.
As of June 2021, there were over 55 000 ships in the world’s merchant fleets. There are no signs that the demand for ballast water treatment systems will be slowing down any time soon.
In 2000, Optimarin installed the world’s first ballast water treatment system on board the cruise ship Regal Princess, and has since sold ballast water treatment systems to more than 1 200 vessels.
