When a US warship in Croatia needed ductwork to be cleaned in just six days, System Hygienics was able to help.
The USS Mount Whitney was dry-docked at Viktor Lenac Shipyard in Rijeka, Croatia, with two local companies contracted to complete the clean. However, the scale of the project and quick turnaround required led them to enlist the help of Irish ductwork cleaning company Jetvent, which in turn contracted System Hygienics to join the team.

System Hygienics and Jetvent each sent two supervisors to Croatia. They traveled by van over a period of three days, transporting the company's Jetvent cleaning equipment. According to Darren Ling, director of System Hygienics, the difficult part of the job was seeking the necessary documentation to comply with Croatia's customs regulations as its not an EU country, the job itself was fairly straight forward.

System Hygienics and Jetvent cleaned 4,000m of ductwork, about a quarter of the warship, while Navy personnel and civilians worked on board. As the ship was dry-docked, no one was living on board at the time.
