Up to 50% Smaller Than Others

The Trojan Marinex BWT system is purpose-built for the marine environment and provides filtration + ultraviolet treatment in a single, compact unit. Our compact technology integration is unique. Others keep their treatment methods separate, which increases footprint and makes for cumbersome retrofitting.

Conventional Design vs. Our Design

Listen in as Andrew Daley (Trojan Marinex Product Specialist) chats with Marine Log Magazine about the importance of a compact ballast water treatment system and how, with in-depth research and rigorous product development, we were able to engineer a system that is up to 50% smaller than others in the industry.

Brian Petri, Research Director, Trojan TechnologiesTuesday, September 27, 10:55 – 11:55

Understanding the use of the MPN method in ballast water testing


  • How is the MPN method adapted to ballast water testing?
  • Understanding validation for methods used in the Environmental Technology Verification (ETV) Program protocol

Andrew Daley, Product Specialist, Trojan Marinex


Tuesday, September 27, 14:15 – 15:15

Manufacturers’ question time


  • Having heard about the key factors to consider in system installation, get to grips with the different systems available on the market. Each manufacturer will join your table for a 10 minute quick-fire discussion, so make the most of this opportunity. The discussion will then be opened out to the floor for a final Q&A.

We hope to see you in Miami!

Ballast Water Management: Getting Ready For September 2017

The ratification of the International Maritime Organization (IMO) Ballast Water Management (BWM) Convention has set the date in which the Convention will enter into force and, subsequently, when the standards in regulations D-1 and D-2 will begin being enforced under Port State Control (outside of the U.S.).

Starting September 8, 2017, vessels with greater than 400 gross tonnage will be required to manage ballast water by either installing a ballast water treatment system or performing ballast water exchange (BWE). All vessels must also maintain a ballast water management plan and record book.

  • Operations are more hazardous than normal port operations
  • Could result in lengthy delays
  • Operations may put the safety of the vessel in jeopardy; careful planning is required

What Is Ballast Water Exchange?

BWE involves the substitution of water in vessel’s ballast tanks in an effort to limit the probability of transferring and introducing aquatic invasive species into waterways. This substitution can be accomplished by utilizing one of three methods deemed acceptable by the IMO. These methods include sequential, flow-through, and dilution.


BWE is an interim requirement for existing vessels without a treatment system installed. Regulations state that exchange be conducted at least 200 nautical miles from land and in water at least 200m in depth, otherwise in water at least 200m in depth and as far from land as possible or in a designated BWE area. Upon a vessel’s first renewal survey after September 8, 2017, BWE is no longer permitted, as it is at this time that the vessel must begin complying with D-2 ballast water discharge standards.

BWE/BWMS Compliance Timeline

Three Reasons Why BWE May Not Be Appropriate For All Vessels

  1. The vessel’s ballast pumping and piping arrangement, and approved loading conditions may hinder or prohibit performing open-sea exchange
  2. The vessel may not be able to conduct exchange because the route has insufficient distance or water depth
  3. Conducting exchange depends upon favorable weather and sea surface conditions

We encourage you to refer to the most recent regulations and guidelines on ballast water exchange, and promptly develop a ballast water management plan approved by the vessel’s classification society.


IMO Resolution A.1008(28)

BWM Convention Ratification

IMO BWM ConventionThe spread of aquatic invasive species is now recognized as one of the greatest threats to the ecological and the economic well-being of the planet. Today, with the ratification of the International Maritime Organization (IMO) Ballast Water Management (BWM) Convention, the global marine community has taken a significant step forward in its effort to mitigate this threat.

“This outcome was possible from the contribution of countless stakeholders around the globe who recognize the environmental and economic impact of this threat and continue to work toward global regulations that better serve the marine industry,” says Mark Kustermans, Market Manager at Trojan Marinex. “Trojan Marinex and our partners are steadfast in our support of these efforts and of our customers as we move forward.”

The BWM Convention will enter into force on September 8, 2017. The Convention states that all vessels will be required to manage their ballast water on every voyage by treating it using an approved ballast water management system. Discharge standards are set by IMO Regulation D-2, which establishes numerical limits for different size classes of organisms that may be released in specified volumes of water. You can learn more about these limits, as well as compliance dates, here.

The Trojan Marinex BWT product suite initially achieved IMO Type Approval in March 2014.

The Inline Lamp Driver – an Industry First

The Trojan Marinex Ballast Water Treatment (BWT) system (already up to 50% smaller than others in the industry), now includes inline lamp drivers, enabling a substantial reduction in cabling and electrical panels. With this innovation, total system footprint has been further reduced by up to 30%. The inline driver configuration of the entire Trojan Marinex BWT product suite, consisting of models ranging in flow rate from 150 m3/h to 1,500 m3/h, received International Maritime Organization (IMO) Type Approval by DNV GL on July 8, 2016. Both a 150 m3/h and 250 m3/h unit will be on display at SMM 2016 in Hamburg, Germany.

Inline Lamp Driver

Drivers are independently sealed at the factory and passively cooled during operation. Visual indicators enable crew to easily monitor lamp and driver status.

“Research and science, in combination with rigorous product development, enables continual, meaningful innovation,” says Mark Kustermans, Market Manager at Trojan Marinex. “We immediately recognized the synergistic advantages of connecting our UV lamp and drivers together. It’s an industry first which allows our system to provide consistently lower power draw in an even smaller footprint.”

Recent orders indicate that the system’s inline driver configuration has immediately resonated with shipowners and market needs.

The Trojan Marinex BWT system has maintained its purpose-built design and proven TrojanUV Solo Lamp Technology, but now integrates the inline lamp driver innovation to further reduce footprint while maintaining industry-leading low power draw. Footprint and power draw are two of the most critical parameters for the upcoming retrofit market.

“Previously, power draws for UV systems were quite high for vessels with larger flow rates,” says Kustermans. “However, with our low-energy solution, larger vessels are no longer forced to use a chemical-based system – they can now utilize and benefit from UV technology. For example, our 1000 m3/h system has a maximum installed power requirement of 44 kW. This enables larger vessel owners to readily install the system within the available power on a vessel.”
