Hapag-Lloyd cruise ship optimisations cut fuel spend
Line optimisation by DNV GL resulted in more efficient hull forms for Hapag-Lloyd's new cruise ships
Hapag-Lloyd Cruises’ new expedition ships will burn 10% less fuel as a result of design changes made after optimisation work with DNV GL.
The HANSEATIC nature and HANSEATIC inspiration are currently construction at Vard shipyards in Romania and Norway and are expected to launch in April and October 2019. During the initial design and conception phase, DNV GL experts created and explored more than 100,000 hull variations for the vessels.
Henning Brauer, head of new builds, Hapag-Lloyd Cruises, said: “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.”
The efficiency of the hull form was optimized using DNV GL’s unique formal optimization approach. Another 10,000 hull designs were analysed, with the most promising candidates undergoing high fidelity computational fluid dynamic (CFD) analysis to confirm the results. Finally, the stern was optimized for passenger comfort by minimizing impact from slamming.
“Because these ships will have the highest ice class possible for passenger vessels, PC6, fuel consumption is an essential factor in their economic feasibility,” added Juryk Henrichs, senior project engineer, DNV GL – Maritime.
Knut Ørbeck-Nilssen, CEO, DNV GL – Maritime, said: “We are very pleased to have been able to offer an optimisation solution that demonstrates that efficiency and sustainability can go hand in hand. These results show that by bringing greater computing power and smart software to the ship design process we can help to unlock efficiencies for our customers.”
