China’s first-ever cruise ships will use system for refrigeration of all food and beverages.
SWS is building two cruise ships that will employ GEA's transcritical CO2 system
German manufacturer GEA will be equipping two new Chinese cruise ships with transcritical CO2 refrigeration systems – the first two cruise ships ever built in China, the company says.
GEA has also supplied an ammonia/CO2 cascade system to a Dutch fishing trawler, the second largest in the world, according to the company.
In May 2019, GEA signed a contract for transcritical CO2 refrigeration technology with Shanghai Waigaoqiao Shipbuilding (SWS), China, a subsidiary of China State Shipbuilding Corp (CSSC). SWS is building the two cruise ships for the new Chinese brand CSSC Carnival Cruise Shipping Ltd.
The agreement between GEA and SWS provides for the supply of refrigeration and freezing for all food and beverage refrigeration equipment on two cruise ships. The first ship will be delivered in 2023.
"The cruise market is booming worldwide,” said Marc Prinsen, GEA’s head of application center utilitiesmarine. “In China alone, growth to 4.5 million Chinese cruise passengers is forecast by 2020. This will be the first newly built cruise ships to be equipped with this type of sustainable technology. This is a really important reference project and we believe it will lead to a major spin-off."

GEA signed a contract last year with P&O Cruises, part of Carnival Corporation & PLC, the world's largest commercial cruise ship operator, to supply its transcritical CO2 refrigeration technology; the system has already been installed on board the Arcadia, a 2,000-passenger ship from P&O Cruises, where it provides refrigeration for all the ship's food and beverage refrigeration systems.
GEA also signed a contract with UAB Atlantic High Sea Fishing Company, which is a subsidiary of GEA’s Dutch customer Parlevliet & van der Plas. Under this contract, GEA equipped the FV Margiris with an NH3/CO2 cascade system.
The use of CO2 technology is relatively new in the marine business as it is difficult to develop flexible CO2 cooling systems that can be safely installed in the confined and mobile environments of seagoing vessels, said GEA.
The modular transcritical CO2 systems GEA is supplying for vessels operate with multiple GEA Bock compressors. Redundancy is built into the system and “it can be tailored to almost any available space on board and are designed to operate safely, robustly and reliably even in difficult weather conditions,” GEA said.
