Wärtsilä to supply engines and other systems for Viking Line’s newbuilding

The Helsinki based technology group Wärtsilä will supply the engines, the navigation system, and a broad scope of other products and systems for a luxury and environmentally friendly ferry being built for the Finland based operator, Viking Line. The ship is being built at the Xiamen Shipbuilding Industry yard in China and there is an option for a second vessel. The order with Wärtsilä was booked in October 2017.

Six Wärtsilä 31DF dual-fuel engines running primarily on liquefied natural gas (LNG) will provide the propulsion and power for the vessel. The diesel version of this same engine has been recognised by Guinness World Records as being the world's most efficient 4-stroke diesel engine. This will be the first marine application for the dual-fuel version. The combination of high efficiency, low fuel consumption, and the reduced level of exhaust emissions from operating on clean burning LNG, is expected to create low operating costs and a minimal environmental footprint.

Wärtsilä will also supply its LNGPac fuel storage and supply system and an advanced Compact Silencer System (CSS), high quality bow thrusters, the ballast water management system (BWMS), and its Nacos Platinum integrated navigation system. The Nacos Platinum system integrates various functions into a single system, allowing the vessel to be navigated, controlled, and monitored from several onboard positions, thus providing unequalled flexibility and convenience. The Wärtsilä BWMS is designed to render the ballast water discharge harmless of invasive species. Legislation making this compulsory came into effect in September 2017.

The recently launched Wärtsilä SmartPredict system is also included in the overall scope. This innovation is designed to provide ships with greater safety and more efficient operations by displaying the vessel's predicted future position and heading. It evaluates the wind and sea forces affecting the vessel to provide advanced motion prediction and has a configurable prediction time display.

"A new era in ferry operations was established in 2013 when Viking Line's 'Viking Grace' with Wärtsilä dual-fuel engines became the world's largest RoPax ferry to operate on LNG fuel. This latest Viking project represents another milestone as it will be the first vessel fitted with the highly efficient Wärtsilä 31DF engines. Both cases highlight the value our know-how and technology brings to our customers," says Roger Holm, President, Wärtsilä Marine Solutions.

"The value of operating with Wärtsilä engines fuelled by LNG has been well established through our experience with the 'Viking Grace'. Furthermore, the LNGPac fuel system provides the necessary safety and non-stop operation required, so we had no hesitation in once again specifying Wärtsilä for this project," says Jan Hanses, President and CEO, Viking Line.

Commencing in early 2021, the new vessel will operate across the Baltic Sea between Turku, Finland and Stockholm, Sweden. The ship is the first LNG fuelled ferry of this size and standard to be built in China.

Aboa Mare has Provided the First Basic and Advanced Level IGF Course in Turku, Finland to ESL Shipping

Liquefied natural gas (LNG) is a new, more environmentally friendly fuel for the maritime industry, as LNG does not emit soot or other particles during combustion.

It is cost-efficient in marine transport over long distances. Aboa Mare has met the maritime industry’s training needs and offers Basic and Advanced training for mariners working on board vessels subject to the Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code). Aboa Mare is the first Maritime Academy in Finland, offering Basic (A-V/3, paragraph 1) and Advanced (A-V/3, paragraph 2) training for personnel on ships subject to the IGF Code.

The Finnish Maritime Authorities approve that the required 30 sea days on board an IGF ship, including three LNG bunkering operations for the Advanced certificate STCW Regulation V/3 [8.2], can be substituted with a separate IGF simulator course. The IGF courses are a result of the cooperation between Aboa Mare, Meriturva, Wärtsilä Land and Sea Academy, ESL Shipping and the Finnish Maritime Authorities.

The International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code) entered into force on January 1st, 2017. The IGF Code addresses ship design, construction and equipment, as well as operational and training concerns (

Aboa Mare offers comprehensive Basic and Advanced level training including practical fire-fighting exercises subject to the IGF Code. Aboa Mare’s Basic and Advanced IGF Code courses also comply with the requirements laid down in the International Convention on Standard of Training, Certification and Watchkeeping for Seafarers (STCW).

The Basic level course intends to provide Basic training for seafarers responsible for designated safety duties associated with LNG fuel care, use or emergency response on board ships subject to the IGF Code. The Advanced level course intends to provide Advanced training for masters, officers and all personnel with immediate responsibility for the care and use of fuels and fuel systems on ships subject to the IGF Code.

– This course is an excellent example of seamless cooperation needed between different stakeholders, when introducing new environmentally friendly technology and solutions. We have been very satisfied with the course syllabus, organizer, facilities and flexible service received from our partners on this project, says Mikko Rausti, Sea Personnel Manager at ESL Shipping.

DNV GL line optimization brings 10% fuel savings for Hapag-Lloyd Cruises’ new expedition cruise vessels

Design changes made as a result of working with DNV GL has resulted in projected annual fuel savings of more than10% 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.”

After the initial assessment, the efficiency of the hull form was optimized within the given constraint set using DNV GL’s unique formal optimization approach. During this phase, another 10,000 hull designs were analyzed, 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,” adds Juryk Henrichs, Senior Project Engineer, DNV GL – Maritime. “With roughly 7,000 CPUs doing the heavy lifting, our unique form-parametric hull model was able to identify the optimal design to meet Hapag-Lloyd Cruises’ specifications.”
