Data driven design to save ten per cent on fuel for Hapag-Lloyd Cruises

A data analytics programme applied to the design of two new Hapag-Lloyd Cruises passenger expedition ships, currently under construction at the Vard Shipyard in Romania and Norway, has resulted in projected annual fuel savings of more than ten per cent, the company says.

{mprestriction ids="1,2"}DNV GL began working with Hapag-Lloyd Cruises during the initial design and conception phase for the two vessels, HANSEATIC nature and HANSEATIC inspiration, creating and exploring more than 100,000 hull variations for the vessels, applying the computing power of approximately 7,000 CPUs.

Analysis of the various hull forms, and of the impact on fuel consumption of interactions between the hull form, the initial general arrangement and stability requirements, was then applied by Hapag-Lloyd Cruises and Vard in choosing the optimal design for the new ships, which are expected to launch in April and October 2019.

After the initial assessment, the efficiency of the hull form was then optimised within the given constraint set using DNV GL’s formal optimisation approach. During this phase, another 10,000 hull designs were analysed, 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’,” said 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 impact 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.”{/mprestriction}

    The contract expansion will see another eight Klaveness vessels use Veracity. According to the companies, the pilot project, which began in 2019, indicated that a reduction in fuel consumption was possible by combining and visualising operational, positioning and engine data.

  • Wärtsilä Translink certified compliant with latest DNV GL cybersecurity rules

    Wärtsilä has been awarded a DNV GL type-approval certificate and cybersecurity certification by the International Electrotechnical Commission (IEC) for its Translink solution, part of the company’s connected ECDIS concept.

    The cybersecurity verification has been issued according to the updated DNV GL rules and the internationally recognised standard for cybersecurity for bridge and navigation systems, IEC61162-460.

    Translink is a system that comprises the hardware, router, and software components. Together, they ensure that data can be encrypted as it is transmitted across the network using the latest protocols of cybersecurity. The certificates validate that the Translink Gateway has the key components in place to ensure secure operations. They also denote Wärtsilä’s commitment to developing cyber secure products in support of critical infrastructure and operations.


    Wärtsilä achieved the certification after in-depth analysis by DNV GL, verifying that the system follows best practices on cybersecurity. The product is type approved and ready to be applied for vessels with the DNV GL Cyber Secure Class Notation, while the IEC reference aligns it with the industry prerequisites, as well as any regulatory requirements.


    “Digitalisation offers more efficient and better ways of operating and designing vessel equipment, such as integrated voyage planning including the remote update of ECDIS charts. With a 3rd party cyber verification, vessel owners can take advantage of such new technologies with assurance that it follows best practice cyber security design. Wärtsilä Voyage has achieved the first Cyber Secure Type Approval using the updated February 2020 Type approval programme,” said Jarle Coll Blomhoff, group leader Cyber Safety & Security, DNV GL.


    “Great work has been done to ensure that Wärtsilä Translink not only complies, but sets the standard for ship-to-shore data exchange through secure channels. The full compliancy with IEC61162-460 and DNV GL Cyber Secure rules takes Wärtsilä Translink to an unprecedented level of security, quality and trust,” commented Anton Karelskiy, solution manager, Wärtsilä Voyage.


    Following more than ten years of experience in connecting ECDIS with implementation and certification of four generations of cybersecurity solutions, Translink provides a cyber secure gateway for Wärtsilä Navigation systems to the outside world, including for connecting ports or revolutionising voyage planning with the new Wärtsilä Navi-Planner.

  • Anglo-Eastern extends DNV GL’s Navigator Port technology to fleet

    Ship manager Anglo-Eastern has completed the successful roll-out of DNV GL’s Navigator Port to its fleet of more than 600 vessels. 

    Navigator Port software is used onboard several thousand ships for management of port documentation, assisting seafarers in navigating the administrative and regulatory complexity of port clearance and passage through controlled waters.

    “One of the most time-consuming tasks onboard is preparing port documentation,” said Captain Pradeep Chawla, managing director, QHSE and training at Anglo-Eastern. “We have brought in Navigator Port to reduce the administrative burden and ensure quality of the reporting. This is especially important on ships where the port of call is not known well in advance.”

    “The addition of Navigator Port to our ships is part of our overall digital transformation effort across our fleet,” stated Capt. Bjorn Hojgaard, chief executive officer of Anglo-Eastern. “We are evolving our shipboard technologies for the future with smart solutions, and DNV GL’s offering complements our vision for a digitally enhanced fleet.”

    Navigator Port facilitates compliance with requirements from charterers and port authorities. Approximately 1,400 port clearance forms are automatically filled in with ship data, so the required paperwork can be prepared in a few minutes. The system reports directly to maritime authorities, such as the Electronic Notice of Arrival/Departure (eNOAD) to the United States Coast Guard, and the Electronic Pre-Arrival Notification (ePAN) to the Maritime and Port Authority of Singapore.

    In addition, Navigator Port includes a database of information about all the world’s ports and terminals based on publications and data from IHS Markit Ports & Terminals Guide, ADMIRALTY List of Radio Signals (Volume 6) and other sources. In all, paperwork can be reduced by up to 90 per cent.

    “We’re very pleased about the successful implementation of Navigator Port across the Anglo-Eastern fleet. Navigator Port makes it easier for the crew to report accurately and efficiently, which ultimately means that they can focus on their primary responsibility: safe and sound navigation,”  said Kenneth Vareide, CEO of DNV GL – Digital Solutions.
