Kongsberg Steel Waterjet S-4L

Kamewa S-4L waterjet: High-performance propulsion for large vessels, offering superior manoeuvrability, durability, and efficiency. Precision manoeuvrability and reliability for large-scale vessels across all segments The Kongsberg Maritime Kamewa S-4L waterjet delivers exceptional efficiency and durability for high-performance vessels. Designed with advanced hydrodynamic technology, it ensures superior manoeuvrability and reliability in the most challenging conditions. The S-4L waterjet is part of Kongsberg Maritime’s steel series waterjets, engineered for vessels requiring robust propulsion and precise control. At its core is a fully duplex stainless steel mixed-flow pump, optimised through computational fluid dynamics (CFD) and extensive testing at our very own Hydrodynamic Research Centre. This combination ensures outstanding performance across a wide range of operating profiles. The S-4L features fully duplex stainless steel components, ensuring long service life and minimal maintenance. Built-in bearings maintain correct impeller positioning and tip-clearance, ensuring highest pump efficiency in the market segment. Our unique reversing bucket and steering nozzle design provide superior position keeping and handling at both low and high speeds, reducing fuel consumption and emissions during harbour manoeuvres while maintaining speed in high-speed turns. Our waterjet control systems range from standardised solutions to multi-station configurations and can be fully customised according to customer requirements. By choosing our control systems, we can guarantee safe and reliable operations with highest system performance.
