105 Silverstream The Silverstream System reduces frictional resistance between the water and the hull surface, reducing net fuel consumption and associated emissions by an average of five-10 per cent. The system is unique in that it is the only proven air lubrication technology that can be retrofitted in 10 days or less, as well as being applicable to newbuilds. It lasts the lifetime of the ship, is complementary to and can be used in conjunction with other clean technologies. Silverstream has successfully verified the savings that its technology creates through third-party assessment from organisations including Lloyd’s Register, HSVA and the University of Southampton. FEATURE Wärtsilä Wärtsilä’s advanced NextDF technology expands methane slip reduction capabilities for LNG-fuelled, 4-stroke dual-fuel engines and is currently available across three Wärtsilä engine platforms. The solution can reduce methane emissions down to as low as 0.9 per cent of fuel use across a wide load range, while maintaining high efficiency and performance across the load range. By optimising combustion, NextDF supports compliance with tightening regulations and enables lower lifecycle greenhouse gas emissions, providing a practical, scalable pathway to more sustainable passenger vessel operations. SGS SGS, the world’s largest testing company, supports the maritime industry with comprehensive exhaust emissions testing and monitoring services, helping operators comply with requirements including International Maritime Organization nitrogen oxide (NOx) regulations, EU MRV, MARPOL Annex VI, and California Air Resources Board (CARB) standards. From greenhouse gas and NOx testing to opacity measurements, sensor verification, and SCR efficiency assessments, SGS delivers the independent data and expertise needed to keep fleets compliant, efficient, and ready for the future.
