A Game-Changer for Dual-Fuel Engines
LiqTech International, a US-based leader in advanced marine filtration systems, has just secured supplier approval for its cutting-edge Water Treatment System (WTS) to be used in WinGD’s two-stroke dual-fuel engines. This partnership marks a significant leap forward for sustainable maritime technology, as the WTS will be integrated into WinGD’s engines operating in both gas and diesel modes.
The system’s standout feature? Its ability to recycle 80-95% of feed water, drastically reducing freshwater consumption and minimizing wastewater discharge. This innovation aligns perfectly with global environmental regulations, making it a must-have for eco-conscious shipbuilders and operators.
Silicon Carbide: The Secret Sauce
At the heart of LiqTech’s WTS lies its silicon carbide (SiC) ceramic membranes. Known for their exceptional hardness, thermal conductivity, and chemical resistance, these membranes are built to withstand the harshest marine environments. But that’s not all—they also deliver ultra-fine filtration, effectively removing contaminants, oil, and particulate matter from water.
This robust technology ensures that the WTS isn’t just a one-size-fits-all solution. Its modular design makes it adaptable for both retrofits and newbuilds, with the flexibility to scale up capacity post-installation. Whether you’re upgrading an existing fleet or building the next generation of ships, LiqTech’s system has you covered.
WinGD’s Dual-Fuel Dominance
WinGD, headquartered in Winterthur, Switzerland, is no stranger to innovation. Their portfolio includes low-speed engines and gen-sets powered by alternative fuels like methanol, ammonia, and liquefied natural gas (LNG). Their X-DF series, including the X-DF-A ammonia dual-fuel engine, has already garnered significant attention for its stellar performance and regulatory approvals from leading classification societies like Lloyd’s Register and Bureau Veritas.
The maritime industry’s shift toward dual-fuel engines is undeniable. According to Veson Nautical, 65% of 2024’s containership orderbook features vessels equipped with these engines—a dramatic increase from just 4% in 2018. With this surge in demand, reliable water treatment systems like LiqTech’s WTS are becoming indispensable, especially for exhaust gas recirculation (EGR) systems.
A Global Push for Cleaner Seas
LiqTech’s commitment to sustainability extends beyond its WTS. In July 2024, the company partnered with South Korea’s Danbee Marine to market its marine scrubber water treatment solutions. These systems not only meet but exceed the discharge limits set by the International Maritime Organization’s (IMO) Marpol VI regulation, setting a new standard for environmental compliance in the shipping industry.
With over 400 new vessels expected to adopt EGR solutions between 2024 and 2027, LiqTech’s technology is poised to play a pivotal role in shaping the future of maritime operations.
