Touted as the premier gateway to the Asian maritime market, the biennial Marintec China provides a platform for suppliers to showcase their latest marine, ship design, offshore engineering and ballast water treatment technology. The event now attracts over 1,700 exhibiting companies from 32 countries around the world.
The 2015 installment takes place December 1 – 4 in Shanghai, and three of our partners will be exhibiting.
GEA will be in Hall N2, Booth D11-04. Visit them to see the Trojan Marinex BWT 250 unit.
Damen will be in Hall N1, Booth D49. Visit them to hear more about their one-stop-shop retrofit solutions.
Specs will be in Hall N1, Booth H61-10. Visit them to hear more about their ballast water treatment services and support.
Our ballast water treatment systems are part of Damen’s One-stop BWT Retrofitting Service – a comprehensive service that assists vessel owners in the selection, installation and service of ballast water treatment systems. From selection to surveying, all the way to installation, the holistic solution that they provide helps simplify the process for owners.
The advantage of the BWT Retrofit Service is that Damen can provide a true one-stop-shop. They have many yard facilities, including 40 dry docks, located around the world. So if a vessel is coming in for its special survey at the point that the installation of a BWT systems becomes mandatory, they can do both at once, providing a single turnkey solution.
Preparation is key for a successful retrofit project, and that’s why Damen is following a well-defined process which includes an on board survey, 3D scanning and engineering. The video below gives a great overview of these capabilities. In it you will see the Trojan Marinex BWT 250 installed in a horizontal configuration.
BWMTech conferences provide a platform for shipowners, ship yards, system manufacturers and government regulators to share ideas and strategies about ballast water treatment. The 2015 UK conference takes place December 8 – 10 at the Congress Centre in London.

Highlights From The 2014 Event
We attended the 2014 event, and found it to be quite insightful. Watch this video to hear what other attendees had to say.
With the wide array of ballast water treatment technologies and solutions on the market, not only should vessel owners assess a manufacturer’s ability to achieve United States Coast Guard (USCG) Type Approval, they must also carefully consider operational expenditure (OPEX).
Here are six questions and answers that should help as you continue to evaluate various ballast water treatment system suppliers.
1. How prominently should OPEX figure into the buying decision vs. capital expenditures (CAPEX)?
The answer depends on the expected operational life of the vessel. Annual operational expenses can range from 3% to more than 15% of the capital cost of the treatment equipment. A significant portion of these expenditures only occur in later years when replacement and maintenance of the equipment become necessary, so owners deciding to keep a vessel for more than 3 – 5 years should consider OPEX as an important factor.
2. What important advantages do various technologies provide that minimize OPEX?
All technologies have operational benefits that can minimize OPEX. For instance, Electrochlorination systems can be very efficient at delivering the necessary dose when ballasting seawater, and a few are designed to reduce electrode scaling by using triple tube electrode (TTE) technology to lengthen the time between cleaning. Alternatively, UV systems are not affected by salinity or temperature, which allows for consistent and reliable performance in all ports. Furthermore, the Trojan Marinex BWT system is equipped with TrojanUV Solo Lamp™ Technology. Typical medium-pressure lamps have a life expectancy of 4,000 hours. The Solo Lamp, however, has a life expectancy of beyond 10,000 hours of ballast water treatment operation, which is equivalent to 10+ years.
3. Compliance is the driving force for installing a ballast water treatment system. Are there specific compliance costs that shipowners should be aware of?
Compliance costs may include regular calibration of equipment sensors and recurring sampling of the ballast water discharge to evaluate the levels of active substances and disinfection by-products. The USEPA’s 2013 Vessel General Permit (VGP) specifies a monitoring schedule for residual biocides sampling of two to four times per year, tested independently, submitted as reported and not averaged, and annual calibration of monitoring equipment. This dual-compliance requirement for all active substance systems (biological and residual biocide monitoring) increases the cost of compliance over physical treatment methods (e.g., UV) and is an additional consideration when evaluating technologies.
4. Planned replacement of consumables or equipment is an important consideration when evaluating OPEX. How should a shipowner seek confidence that these expenses are accurate and representative?
Technology is best proven in the field, but the reality is that few ballast water treatment systems are currently in operation, and disclosure of any operational information has been limited. In light of this, relevant data should be provided by the manufacturer that demonstrates the system’s expected performance based on years of testing, experience during the Type Approval process, and track record in other applications. Life cycle testing of critical components is becoming standard practice in the marine industry, and many manufacturers may be able to share the degree of which they stress-tested their technology to support the proposed replacement schedule.
5. Unplanned maintenance can greatly impact OPEX. What are some risk areas that shipowners should be aware of?
Anticipating problems requires a degree of familiarity with the equipment and knowledge of what can go wrong. All systems attempt to remain clean during operation, but over time, scaling, biofouling, and sediments can accumulate on critical components and inversely affect performance or prevent treatment. Similarly, high concentrations of active substances can, over time, cause premature seal failure or adversely affect ballast tank coatings and ballast piping systems. A regular inspection program is necessary to identify early warning signs and resolve issues.
6. Periodic cleaning may be important to maintain the performance of a ballast water treatment system. What environmental conditions will impact the frequency of cleaning?
Similar to other marine equipment, periodic cleaning of the equipment may be necessary to maintain performance over the life of the system. Since ballasting rarely takes place in clear marine waters, systems will treat water with sediments, contaminates, and high organic loading that may exceed the capacity of the system. The combination of heavy sediment and biological material loading has been known to affect filters and disinfection equipment uptime, and should be considered when ballasting to signal potential problems.
Hopefully this Q & A was helpful. If you have any additional questions about OPEX, please do not hesitate to contact us.
