The type approved Optimarin Ballast System is based on filtration as pre-treatment and high doses of UV irradiation for inactivation of marine organisms, viruses and bacteria, without affecting the normal operation of the ship. Ballast water is UV treated both during ballasting and de-ballasting to ensure the dual UV effect. Ballast water is only filtered during ballasting.
The OBS is one of very few treatment options that does not use or generate chemicals or biocides in its treatment or cleaning processes. It is based on the idea that such systems should be environmentally sound, simple, flexible and easy to install, and capable of operating on both newbuilds and existing vessels.
The Optimarin Ballast System is easy to install on board existing ships (retrofit) as well as on newbuilds. The modulized system is very flexible, with a relatively small footprint and weight, and will fit vessels of all kinds and sizes. The OBS can be delivered as a complete skid or as a customized solution. It accommodates a wide range of ballast water capacities and can handle flows up to 3.000 m³/h (or higher upon request).
The Optimarin Ballast System is normally installed in the pump or engine room and in close proximity to the ballast pumps. The OBS can be delivered in a container, on a skid or in separate pieces to allow for easy installation in most any available space. The equipment can be installed horizontally, vertically, on or suspended below deck, along the ship’s side or in several separate locations. It is relatively low weight and adds no extra noise. The OBS utilizes every square meter and does not require much space, this makes it a cost-efficient solution.
