Carrier Refrigeration

As the saying goes, "May you live in interesting times." Whether a blessing or a curse, it seems appropriate for the era we live in today. For the container shipping industry, overcapacity, coupled with the ever-present risk of low freight rates, continues to affect the major lines. Some of the largest carriers have disappeared over the last three years, primarily through mergers and acquisitions, which may ultimately result in helpful synergies and the elimination of excess capacity. Until then, shipping lines continue to contend with tight margins. Still, there are positive aspects to these interesting times we live in. One, in particular, is the pace of technological innovation that creates new opportunities for businesses to excel. For its part, Carrier Transicold has a lengthy track record of adding value for customers through innovation that delivers operational benefits, as discussed in several of this issue's stories. Seatrade, for one, has invested in new container ships as part of its fleet evolution. As told on page 8, Seatrade chose Carrier Transicold's most efficient container refrigeration unit, the PrimeLINE ® unit with EDGE technology, to complement these vessels. Seatrade knows that when less energy is required to power refrigeration units, less fuel needs to be burned by a ship's power plant, saving costly fuel while reducing emissions. The facing page salutes Maersk Line's addition of its first 100 NaturaLINE ® units, which offer a natural refrigerant- based route away from synthetic refrigerants with high global warming potential (GWP). The need to push toward low-GWP solutions is underscored by the recent Kigali amendment to the Montreal Protocol, which provides global timelines for the phasedown of hydrofluorocarbons, as we discuss on page 6. These are not just interesting times but exciting times with tremendous upside and opportunity. Living in Interesting Times Striving to further reduce the environmental impact of its global shipping operations, Maersk Line, the world's largest container shipping line, has added the first 100 of a total of 200 refrigerated containers chilled by the NaturaLINE ® natural refrigerant- based system. The highly efficient NaturaLINE is the first container refrigeration system to use the natural refrigerant carbon dioxide (CO2), which is a safe and non-ozone depleting gas with a global warming potential (GWP) of 1. There is no additional global warming impact resulting from any potential refrigerant leaks, as is the case with traditional systems, since NaturaLINE uses carbon dioxide repurposed from outdoor air. It is also unaffected by phasedowns of hydrofluorocarbon (HFC) refrigerants and is relatively inexpensive. It is classified as A1 for low toxicity and no flame propagation. "To meet our sustainability goals and stay ahead of the new EU legislation, Maersk Line is keen to carefully evaluate all alternatives to the current synthetic refrigerants," says Ingrid Uppelschoten-Snelderwaard, head of global equipment, Maersk Line. "The NaturaLINE system is an advanced technology with interesting potential for reefers. We chose it after laboratory testing of the unit's performance with perishable and frozen commodities and look forward to gaining further operational experience with the system." "We are pleased that Maersk Line sees potential in the NaturaLINE unit to help it achieve its ambitious sustainability goals," says David Appel, president, Carrier Transicold & Refrigeration Systems. Maersk Line Adds 100 NaturaLINE ® Units For Operational Testing " Carrier shares Maersk Line's goals of improving the efficiency and sustainability of global container shipping, which protects the world's perishable food supply and other goods as they move through the cold chain to the consumer." 2
