Cargoshell Reefer awarded CSC certificate
Cargoshell BV has been awarded a CSC certificate from Germanischer Lloyd for its composite panel reefer container.

The Cargoshell dry container was CSC certified in 2012, and last month the Cargoshell Reefer was awarded the CSC certificate from Germanischer Lloyd at Drehtainer in Valluhn, Germany. The company claims it is “the first composite sea container to meet these strict standards”.
Dr.ir. Albert ten Busschen, who is responsible for the Cargoshell design, said it was developed with a clear set of criteria. “A new schedule of requirements was drawn up for the Cargoshell Reefer. This container had to have thermally insulated walls, it needed to be hermetically sealed and had to have an integrated refrigerator unit. Moreover, the design had to be suitable for mass production and capable of competing with existing containers in terms of price. The modifications entailed re-testing the strength of the prototype as well as all of its components.
“During the five-month research period and the seven-month manufacturing period, we conducted a variety of interim tests on the Reefer’s details and components as not a single part may fail the CSC test. For this purpose, we set up special tests, lots of specific details underwent FEM analyses and the results were fully documented. Only when these analyses had proven convincingly that the schedule of requirements would be met, could production be started,” Ten Busschen said.
As previously reported in WorldCargo News, the Cargoshell reefer uses composite panels for walls, ceiling and door, together with its own design “T” panels for the floor. The composite panels are built “like an integral sandwich with reinforced outer skins and an insulating inner layer” in a single manufacturing process. This, the company claims, eliminates problems with delamination that occur in conventional reefers, where insulation is injected between steel panels. “What’s more, we also retain the other benefits of the material such as its lightness, strength, resistance to corrosion, hygiene and radio transparency,” added Ten Busschen.
Cargoshell uses fibre-reinforced plastic composite material. “The fibre reinforcement means we create a material that has great strength and low weight. The fibres can be built up and laid in different directions. In most of the parts, we use glass fibre; in the supporting columns and corners of the container we use carbon fibre, which, despite its low weight, has outstanding strength and rigidity. By making the supporting columns from carbon fibre, we were able to pass the stacking test, in which each of the corner posts is subjected to a compression force of no less than 85 tons,” said Ten Busschen.
Cargoshell BV does not intend to manufacture the container itself, and is looking for companies interested in acquiring its intellectual property.
