DNV GL announced in a statement, that its cooperation with Hapag-Lloyd Cruises, has resulted in design changes which are expected to save more than 10% fuel for Hapag-Lloyd Cruises’ passenger expedition ships.
The two vessels, HANSEATIC nature and HANSEATIC inspiration, are currently under construction at the Vard Shipyard in Romania and Norway and are expected to launch in April and October 2019.
At first, DNV GL created numerous hull variations in order to show Hapag-Lloyd Cruises and Vard how the interactions between the hull form, the initial general arrangement and stability requirements would impact fuel consumption.
Finally, the stern was designed in a way that could enhance passenger’s comfort by minimizing impact from slamming.
After that, the efficiency of the hull form was optimized, DNG GL said. To achieve this, another 10,000 hull designs were analyzed, with the most promising candidates undergoing high fidelity computational fluid dynamic (CFD) analysis to confirm the results.
“The design concept for the two new ships was inspired by nature. The vessel interiors have been created to reflect the environments our passengers are experiencing inside the ships. But these are also sensitive environments, so reducing the environmental impacts of our vessels is an integral part of the design concept. Working with DNV GL has allowed us to significantly reduce fuel consumption, which also decreases our overall emissions,” says Dr. Henning Brauer, Head of New Builds, Hapag-Lloyd Cruises.
Lastly, Juryk Henrichs, Senior Project Engineer, DNV GL – Maritime, noted that because of these vessels’ ice class, PC6, fuel consumption is an essential factor in their economic feasibility.
