Norbulk first shipmanager to convert to EU eco-friendly reefer gas
LIVERPOOL's Oceanic Technical Solutions has converted refrigeration plants aboard a Norbulk-managed refrigerated cargo ship to run on refrigerant R407F.
The conversion, which follows the January 2015 European Union F-Gas ban on R22 refrigerant on all European-flagged vessels, is believed to be an industry first marine refrigerant conversion to eco-friendly R407F.
Prior to January 2015, operators like Bermuda-based Norbulk were still able to purchase recycled R22, but the ozone-depleting gas and other Hydrochlorofluorocarbons (HCFCs) are now banned across Europe.
Said Norbulk fleet manager John Taylor: "The success of the refrigerant retrofit has shown the industry that there is a commercially viable alternative. Since the conversion, we have reduced our impact on the environment without affecting cooling performance."
During a scheduled drydocking at a shiprepair yard in Klaipeda, Lithuania, the 6,120-dwt reefer plant aboard was shut down and the entire charge of R22 recovered.
Before the plant could be charged with the new gas, it was pressure tested for leaks, fitted with new gaskets, seals and oil filters, inspected and made leak-tight all pipe work and installed a fixed leak detection system - now a mandatory requirement under the F-gas Regulation (EU).
