The continued importance of gas carriers has prompted Desmi to relaunch its range of cargo pumps, not only for enhanced safety and efficiency, but to cope with the various types of gas which will be a key factor in the green transformation and support the marine industry towards a greener future.

Martin Bro, Global Sales Manager Gas Systems, Desmi, said: “Our NDW range of cargo pumps is designed for LPG and LEG applications, but that’s just the start. The marine business is evolving fast: To reduce carbon emissions, many marine engines are already fuelled by LPG and LEG today, and we expect that this tendency will only increase in the years to come. We’ll probably see an increased need for liquefied CO2 transportation. The evolution of carbon capture and storage technology means that CO2 needs to be shipped to underground storage locations. So, both in terms of fuels and cargo, gas will change shipping, and our cargo pumps support this evolution: They will be developed to handle LNG, CO2, and other liquefied gases, and they can be adapted for use as gas fuel pumps. In short, they will be able to fulfil all future liquefied gas handling requirements.”

The new NDW range marks a return to the market of a proven pump range. For the relaunch, Desmi says it combines this experience with the company’s general expertise in marine pump design and adds a range of technological advances.

Bro continued: “Over the years, we have quite simply become much better at building pumps, and a new Desmi cargo pump is superior to an old one. To take just one example, our design processes have improved through the use of state-of-the-art design and calculation tools. With computational fluid dynamics and stainless-steel casting simulations, we have achieved a highly efficient pump design customised to our customers’ exact requirements. In fact, the efficiency of our centrifugal cargo pumps is approximately 80%.”

While the new cargo pumps are designed and developed at Desmi headquarters in Denmark, they are manufactured at Desmi’s Chinese production facilities – close to the shipyards where the pumps will be installed. This makes pump manufacturing fast and efficient, and since parts and complete pumps do not need to travel the globe several times before being installed, the process is more climate friendly, too.

Shipyards and designers can benefit from reliable long-shaft deep well cargo pumps that comply with all international marine regulations and requirements. Customers can expect full global support from the Danish pump manufacturer – from design, development, and manufacturing to delivery and aftersales service.

Bro added: “Not only is sea transportation of liquefied gas still important; it looks set to be an integral part of the green transformation. Our relaunched range of cargo pumps is ready to support companies now and in future – from LPG to LNG and beyond.”
