Denmark-based marine pump specialist Svanehøj stated Wednesday it may well now supply a high-pressure pump resolution for two-stroke engines as demand for LNG-fueled vessels stays excessive.
The firm describes its resolution as a compact unit with three mixed chilly ends designed for optimum stream and longer service intervals.
High-pressure LNG engines supply decrease gas consumption and considerably lowered methane slips. This is driving a surge in demand for essential parts for LNG high-pressure gas provide methods, which Svanehøj is now prepared to fulfill, the corporate stated.
The Danish marine pump specialist has developed a high-pressure gas pump unit with a drive system and three mixed chilly ends designed for optimum stream and longer service intervals. The new resolution, referred to as “HPP Triplex Unit”, is pre-launched at Kormarine in Busan, Korea, this week.
“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, says Johnny Houmann, CSO in Svanehøj.
Svanehøj said it had designed the HPP Triplex Unit to meet the maritime industry’s demands for leak-free critical components with a long service life.
“The chilly finish consists of an progressive low-pressure sealing association that reduces friction, guaranteeing longer service intervals. To additional scale back upkeep prices, Svanehøj has developed a cartridge resolution for swift sealing substitute. To guarantee excessive effectivity and low-pressure drop, Svanehøj has additionally included a brand new inlet valve design,” the corporate stated.

“In the best situation, all ships would function on carbon-free fuels tomorrow. However, it can take a number of years to determine an infrastructure to fulfill the necessity for liquid renewable vitality. Transition fuels are important for a profitable vitality transition, and pure gasoline is by far the best choice – with vital environmental advantages. In Svanehøj, we’re dedicated to repeatedly innovating our product portfolio designs and repair fashions on the lowest potential environmental lifecycle price,” says Søren Kringelholt Nielsen, CEO at Svanehøj.
According to the corporate, the uptake of LNG has been excessive lately, particularly amongst new buildings.
According to the DNV database for various fuels, there at the moment are 431 LNG-powered ships in operation and one other 539 ships on order, bringing the whole rely near 1,000 vessels. In 2021 and 2022 alone, 462 LNG-fueled ships have been ordered, and within the first 9 months of 2023, an extra 104 ships have been added to the worldwide order e-book.
