Largest gas pump to date

Svanehoj to develop a tailored LPG/ammonia solution for land-based terminal in the U.S.

A landmark order for a major onshore project not only marks Svanehoj’s first large-scale entry into the U.S. land-based terminal market. It also involves the delivery of the largest cryogenic pump in the history of the company. This development further strengthens Svanehoj's position as a trusted global partner for both marine and onshore solutions.

As the marine and energy industries prepare for the transition to green ammonia and other climate-neutral e-fuels, the storage and transportation of liquid energy is facing unprecedented demands.

Based on decades of experience in deepwell pumps for liquefied gas, Svanehoj has been selected to deliver a tailored in-tank pump solution for a new 100.000 m3/hour cryogenic storage tank at a land-based storage terminal in the U.S.

This landmark order is particularly noteworthy because the pump will be used to handle both LPG-and ammonia, and it will be the largest gas pump ever developed by Svanehoj. This project requires further enhancements of existing designs, with work currently underway and delivery planned for the fourth quarter of 2026.

“This project requires a significant upscaling in both size and capacity. A unique combination of our robust deepwell gas pump-design and the patented foot valve system from our fuel pumps have led to the success of winning this onshore contract”, says Claus Mark Hyttel, Sales Manager for Energy at Svanehoj.

Efficient onshore solutions based on advanced harsh environment marine expertise

For this project, the customer required a high-capacity pumping solution capable of handling both LPG and ammonia, prioritizing high levels of safety, efficiency, and reliability.

To meet these requirements, Svanehoj is upscaling its proven deepwell gas cargo pump design, resulting in a record-breaking pump with an 1800 cbm/hour, even larger than the ultra-large units previously delivered for marine applications. This development highlights Svanehoj’s unique ability to adapt advanced marine expertise to the complex challenges of land-based storage facilities.

A key factor in securing this project was Svanehoj’s patented foot valve technology, originally developed for the deepwell fuel Pump with caisson-footvalve pump retraction system, now adapted for the much larger gas cargo pumps to be used in this installation. The foot valve can be activated from outside the tank. In the event of a service requirement, the foot valve system utilizes containment and tank pressure to safely isolate the pump, allowing for quick and efficient extraction. This design not only ensures operational continuity but also meets the highest safety standards, a crucial consideration for facilities located near populated areas.

We think beyond the tank

The pump solution for the U.S. terminal installation will initially handle LPG but is fully prepared for ammonia. With the pump’s motor safely located outside the tank and a state-of-the-art closed sealing system that minimizes the risk of emissions, Svanehoj is providing a solution that adheres to the highest safety and environmental standards. The proven DWG design, with all critical components positioned outside the tank, ensures safe and easy access for maintenance. This not only enhances operational safety but also simplifies servicing and reduces long-term maintenance costs.

”We think beyond the tank, pushing design boundaries to develop more innovative and safer solutions for the future energy infrastructure”, says Claus Mark Hyttel.

With delivery scheduled for 2026, Svanehoj remains committed to pushing boundaries, driving innovation, and partnering with customers worldwide to shape a safer, cleaner, and more efficient future for liquid gas handling worldwide.

With over 14,500 DWG deepwell cargo pumps for marine and onshore applications on reference, this landmark order represents a strategic breakthrough in the U.S. onshore market. It’s the result of more than 15 years of development during which Svanehoj prepared its technologies for a seamless transition from ship to shore.
