Ballast Water Management System

MMC GREEN TECHNOLOGY MMC Green Technology is a relatively young company, established in 2010 as a spin off in the MMC group of companies. The mission was to establish a company focusing on environmental protective solutions for the maritime industry, the upcoming BWM convention and MMCs experience from water treatment systems was the main reason for the timing. MMC Green Technology consists of employees with very long experience from several other companies in the Norwegian Marite Cluster. By knowledge about the high demands in maritime operations we aim to give our customers the best service at all time.

Dedicated and trustworthy, based on feedback and focused on results!

A desire to travel and utilization of natural resources in a harsh environment have developed this maritime cluster into one of the strongest and most innovative clusters in the world, especially within offshore and fishing. The strength of the cluster lies within the many participants in all segments of the value chain – from shipowners to ship equipment suppliers.


= ONE World-class maritime cluster!

NORWAY, home for a tiny 0,1% of the world’s population, controls over 5% of the world’s merchant fleet and has the second largest offshore fleet in the world, after USA!

14 design companies 14 ship yards 18 ship-owner companies 172 equipment suppliers 22.500 employees 40% of the world’s modern fleet

-about the system


MMC BWMS is a state of the art ballast water treatment system. Compact design, intuitive operation, reliable performance and easy maintenance has been the most important design criteria. The ship operators best choice where limited space is available.

MMC BWMS - Filter MMC BWMS make use of self cleaning filters. This filter is the most recognized filter in the Ballast Water business today, and has by far most experience (longest reference list). The Filters consists of several filter candles made out of super duplex steel (chrome-nickel-molybdenum steel) with a filtrations degree of 40 micron Sacrificial anode in addition for even better corrosion resistance Backflush pump is standard configuration, ensuring efficient cleansing of the filter candles Fully configurational backflush setpoint Approximately 5-years service interval

4 power steps, controlled according to UV- light transmission. UV-lamp life time of more than 1000 hour (calculated to approx. 5-years operation on maximum power).

The UV-sensor is places in between the lamps, “looking 360 degrees” and sences all lamps simultaneously. The sensor will detect if a lamp needs to be replaced. Lamps and sensor is covered by the same quart sleeves, and is cleaned by an state of the art wiping mechanism.

UV- light has proved to be a very “clean” alternative to active substances (chemical agents such as chlorine, chlorine dioxide or ozone). Unlike these methods, UV does not produce any disinfection-by-products (DBPs).

MMC BWMS make use of the latest UV-technology commercially available today, based on medium pressure UV-radiation. This is the most efficient UV-technology for Ballast Water Treatment with a UV-radiation wave length of 200-400 nm.


MMC BWMS - CONTROL SYSTEM MMC BWMS make use of a state of the art Control System. Running on a modern industrial computer with an intuitive and user friendly graphical interface. Can be integrated in ships existing automation system (IAS) Easy possibilties for Remote Access Large screen for good overview Informal warnings and alarms Very reliable components Logs all operations, easy to export data, intuitive interface for browsing history Simulator for training purpose

MMC BWMS Type Approval

Germany & Holland Japan

MMC Green Technology has based the treatment system (MMC BWMS) on filtration (first stage) and UV irradiation (second stage). The filter mesh in the first stage is 40 microns. The UV irradiation in stage two damages the DNA structure in the organisms so that they can not reproduce. Systems approved on this basis needs to use both stages (filter + UV) on intake of ballast water, and only stage two (UV) on discharge of ballast water.



THE BALLAST WATER CONVENTION While ballast water is essential for safe and efficient modern shipping operations, it may pose serious ecological, economic and health threats. There are literally thousands of marine species carried in ships’ ballast water. These include bacteria and other microbes, small invertebrates, eggs, cysts and larvae of various species. In some cases, healthy, living fish have been found in ballast tanks. In February 2004, the International Maritime Organization (IMO) adopted the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (the Ballast Water Management or BWM Convention), to regulate discharges of ballast water and reduce the risk of introducing non-native species from ships’ ballast water. The Ballast Water Management Convention will enter into force 12 months after a total of 30 states, representing 35% of the world’s shipping tonnage, has ratified it. As of August 28, 2014, a total of 40 states had ratified the Convention, representing 30,25%.
