Feature 4 | SHIPBOARD WATER TREATMENT Korean’s top-up the BWTS market
With the Ballast Water Convention ratification getting nearer, more ballast water treatment solutions have come on to the market in the last couple of years. Further development of those treatment systems will cater for more vessel types.
K
orean-based Techcross and Panasia offer ship owners two different solutions for the
ballast water convention conundrum, but both claim that their ballast water treatment system can meet ship owner’s requirements. NK, also a Korean ballast water
treatment manufacturer, highlighted the financial issue faced by the ballast water market as the convention lingers on without being ratified. “According to IMO MEPC 55/2/4 document, there will be 1740 new build vessels in 2012 and all existing vessels by 2017 will be expected to have ballast water treatment systems installed. In addition, in June 2007, according to data released in the UK by class society Lloyd’s Register, the system and installation cost shows a difference from US$250,000 to US$2.3 million. If the average price is US$500,000 including installation costs, we expect the size of ballast water treatment market to be worth US$870 million in 2012, US$3.37 billion in 2015 and US$8.97 billion in 2017”, says N J Lee of NK. However, the pressure is still building on
ship owners to adapt to the new regulations and to come to a decision on what type of
ballast water treatment system to install. Techcross has highlighted the features of an electrolysis system. “Regarding UV technology, it’s very safe, compared to the other systems using chemicals. It’s not dangerous to the environment, ship, crew, and ballast tank. And what’s more, its sterilising power has already been proved through various experiments”, states Ahmi Mun of Techcross.
Techcross opts for an electrolysis system. NK’s ballast water treatment for ships. With concerns over certain forms
of treatment systems that use filters as Wilhelmsen withdraws its Unitor system, Panasia still believes that the technology can still work. Its latest product the GloEn patrol GII has a large capacity Multi-cage type filter that has a patent and PCT applications, which has been completed for 14 different countries. It has a reduced footprint and will take up less space in a vessel. Techcross also claims that it is highly efficient at back flushing by increasing the working pressure of individual parts and reducing the loss of pressure within a vessel, allowing for minimum back flushing discharge. Techcross has also highlighted that:
“Type Approval demonstrates a system’s suitability and efficacy, not a performance guarantee. Therefore, the owner and operator are responsible for compliance of the performance standard defined by the IMO (International Maritime Organization) throughout
the vessel’s
life because Type Approval should not be considered as an indication that a given system will work on all vessels in all situations”, says Mun. NA
The patented Vacuumarator™ pump is the most compact, effi cient and reliable vacuum generator available for vacuum toilet systems.
