As demand for LNG-fuelled vessels remains high, Danish marine pump specialist Svanehøj is offering a high-pressure pump solution for two-stroke engines.
The pump, designated ‘HPP Triplex Unit’, is a compact unit with a drive system and three combined cold ends designed for optimal flow and longer service intervals. High-pressure LNG engines offer lower fuel consumption and significantly reduced methane slip. This is driving a surge in demand for crucial components for LNG high-pressure fuel supply systems, which Svanehøj says it can now meet.
Svanehøj CSO Johnny Houmann said: “It is evident that more integrators of fuel gas supply systems are taking on a progressively substantial role in designing fuel supply systems, especially for LNG-powered vessels. Therefore, they increasingly require critical components specially designed to operate under extremely low temperatures and high pressures. Based on decades of experience in low-pressure fuel and cargo pumps for LNG, we made a strategic decision to extend our scope and include a larger part of the LNG fuel supply system by developing a high-pressure pump unit, exclusively designed for maritime purposes.”
Svanehøj has designed the HPP Triplex Unit to meet the maritime industry’s demands for leak-free critical components with a long service life. The cold end includes an innovative low-pressure sealing arrangement that reduces friction, ensuring longer service intervals. To further reduce maintenance costs, Svanehøj has developed a cartridge solution for swift seal replacement. To ensure high efficiency and low-pressure drop, Svanehøj has also incorporated a new inlet valve design.
Svanehøj CEO Søren Kringelholt Nielsen said: “In the ideal scenario, all ships would operate on carbon-free fuels tomorrow. However, it will take several years to establish an infrastructure to meet the need for liquid renewable energy. Transition fuels are essential for a successful energy transition, and natural gas is by far the best option – with significant environmental benefits. In Svanehøj, we are committed to continuously innovating our product portfolio designs and service models at the lowest possible environmental lifecycle cost.”
