November 10, 2017 - Design changes made as a result of working with DNV GL has resulted in projected annual fuel savings of more than ten per cent for the new 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.
Brought in during the initial design and conception phase, DNV GL experts first created and explored more than 100,000 hull variations for the vessels. They worked to give Hapag-Lloyd Cruises and Vard an idea of the technical possibilities of various hull forms and how the interactions between the hull form, the initial general arrangement and stability requirements would impact fuel consumption.
“The design concept for the two new ships was ‘inspired by nature’,” says Dr. Henning Brauer, Head of New Builds, Hapag-Lloyd Cruises.
“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.”
“We are very pleased to have been able to exceed Hapag-Lloyd Cruises’ expectations and offer an optimization solution that demonstrates that efficiency and sustainability can go hand in hand,” says Knut Ørbeck-Nilssen, CEO DNV GL – Maritime.
“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.”
