CO2 REFRIGERATION CONTRACT FOR GEA FROM P&O CRUISES

CO2 REFRIGERATION CONTRACT FOR GEA FROM P&O CRUISES

Tuesday, July 31, 2018  (Comments: 2)

GEA has signed a contract for its new transcritical CO2 industrial refrigeration technology with P&O Cruises, part of Carnival Corporation, the largest commercial cruise ship operator.

The green refrigeration technology has already been installed on board P&O Cruises’ 2,000-passenger ship Arcadia, where it will deliver energy-efficient cooling supply for all of the ship’s food and beverage refrigeration units. Discussions between GEA and P&O Cruises are ongoing with a view to rolling out the CO2 refrigeration plants to additional ships in the existing fleet, and installing the technology directly in new P&O Cruises ships as they are constructed.

Cooling systems that use non-polluting CO2 as an alternative refrigerant to chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are already in use in the retail sector. Developing flexible CO2 refrigeration systems that can be installed safely in the constrained, constantly moving environment of sea-going ships has up to the present been challenging. GEA harnessed more than 100 years of expertise in the design and construction of industrial refrigeration plants to develop the new transcritical CO2 technology specifically for use on ships.

The modular transcritical-type CO2 plants operate using multiple GEA Bock compressors, which are said to be suited to the high pressures of CO2 refrigeration systems. Redundancy is built in the plant, so that failure of one or more compressors will not cause the system to stop working. GEA solutions can be tailored to the available on-board space, and are designed to be safe, robust and reliable, however rough the voyage. Installation can be carried out while the ship is underway, without affecting continued use of the legacy system before switchover takes place.

“We are delighted to announce this major partnership for our groundbreaking transcritical CO2 technology, with P&O Cruises,” sais Marc Prinsen, Head of Application Centre Utilities Marine, GEA. “Every sector of industry is working hard to protect the environment, and that includes saving energy, reducing emissions, and switching to natural refrigerants. As one of the world’s leading technology developers and suppliers to a wide range of global industries, we recognize the key role that we can play by developing sustainable, green technologies, which can be used in challenging processes and settings. Having signed our partnership with P&O Cruises, we are also now in discussions with major international fishing fleets.”

I was fortunate to sail on the Blue Funnel Ship "Gorgon" in the early1960s. The refrigeration system for cargo spaces used CO2 compressors, three stage compressors if my memory serves me right. What's old is new again! Regards Bill Gillbard

CO2 as a refrigerant? I thought that it was no longer used because its critical temperature of 32 Centigrade fell into the zone of some tropical water in places around the world! No matter how high the compression of the gas it will not still not be able to return the CO2 to it's liquid form! I Regards : Jim Stitt
