Moby selects Kongsberg Maritime for emission-saving propulsion upgrade on five ro-pax ferries

Kongsberg Maritime has won a contract to upgrade the propulsion systems on five ro-pax ferries for Italian operator Moby. The vessel upgrades will together reduce CO2 emissions by more than 30,000 tonnes per year.

Moby operates a fleet of ro-pax ferries, operating in the western Mediterranean, including routes between the Italian mainland, Sicily, and Sardinia.

Three of the ships, the Moby Vinci, the Sharden, and the Moby Aki, will all receive a Promas Lite propulsion system, which combines rudder and propeller into one propulsion unit. Two further ships, the Moby Wonder and the Moby Tommy, will each receive re-bladed controllable pitch Kongsberg Kamewa propellers as part of their upgrade.

The Promas propulsion system integrates the controllable pitch propeller, hub cap, bulb, and rudder into one propulsive unit, increasing efficiency and manoeuvrability, and offering significant fuel savings without power losses. Available for either upgrades (Promas Lite) or for new build ships, Promas now has more than 200 references worldwide, across a range of ship types.

CEO of Moby – Achille Onorato, said: “This latest investment into upgrading our fleet demonstrates our continuing commitment to reducing the environmental impact of our operations and improving the overall service we can offer customers. By carrying out a programme of relatively simple upgrades to the propulsion systems, we can reduce our CO2 emissions by more than 30,000 tonnes per year. We’re pleased to be working with Kongsberg Maritime again on this latest project, as we draw on their expertise in efficient propeller design to transform our operations.

“We’re investing in new ships and new routes, innovative services and distribution as well as pricing strategies, a strict, quality-oriented hiring policy and uncompromising attention to safety and the environment”.

Executive Vice President, Global Customer Support, Kongsberg Maritime Jouni Raatikainen, Kongsberg Maritime’s Executive Vice President Global Customer Support, said: “This latest upgrade will deliver significant reductions in carbon dioxide emissions for the five ships, and we’re delighted that Moby has again selected Kongsberg to provide an upgrade solution that supports our common goal to pursue sustainability, reduced fuel consumption and CO2 emissions.

“The Promas Lite propulsion system offers a relatively quick upgrade solution, which delivers efficiency savings and rapid return on investment. Our team at the Kongsberg Hydrodynamic Research Centre, in Sweden, has worked closely with Moby to design propellers that match the operational profile of each individual ship”.

Kongsberg Maritime has provided propulsion equipment to Moby since its early days in the 1970s when the company first started operations, purchasing several ferries from Scandinavian owners. Since then, Moby has grown significantly and invested in its fleet, including the latest new build, the Moby Fantasy.

Kongsberg Maritime has equipment on most of the Moby fleet, suppling controllable pitch propellers, tunnel thrusters and steering gear to almost all their ships.

Updated: Hurtigruten matches modern values with Norwegian heritage

Between 1968 and 1982, Hurtigruten’s ‘Svalbard Express’ provided a vital connection for people and post between mainland Norway and the Svalbard archipelago. This year, the shipowner has revived the iconic route, but this time with a focus on cruising between Bergen and Longyearbyen, and an itinerary matched by both modern comfort and authenticity aboard the newly refurbished ship Trollfjord.

In the intervening 40 years, passenger shipping has changed significantly: today, in addition to different expectations on comfort, cuisine and shipboard services, sustainability is a factor in every decision. For Hurtigruten, upholding responsibility to the planet and its inhabitants has long been a principle for vessel design, construction, design and operation.

For guests, ‘the environment’ is already front and centre along the Svalbard Express route, where the rugged landscapes and rich heritage of the Norwegian coastline are experienced from the comfort of Trollfjord.

The principles of conservation and sustainability have been central to the design of Hurtigruten’s interior spaces. The owner’s objective is for Trollfjord guests to experience Norway not only through breathtaking views and unique excursions but also through the expertly implemented design elements that bring the vessel’s identity to life.

Tasked with conceiving and developing multiple spaces on board Trollfjord – including the main restaurants, cabins, and suites – YSA Design incorporated hard-wearing, responsibly sourced materials from the surrounding environment. The use of organic local resources also helps to establish a meaningful connection between the ship and its setting.

A prominent feature of Trollfjord’s design direction are the patterns, textures and artistic flourishes inspired ny the indigenous Sámi people, whose communities inhabit several parts of Scandinavia including much of the region covered on the ship’s sailing route.

Traditionally, Sámi manufacture items for everyday use from raw materials available in their surroundings, and in designing Trollfjord’s casual dining venue, Brasserie Árran, YSA echoed this approach through the use of natural elements like wood, leather and reindeer hide. These are complemented by woven textiles and traditional crafts, which add further detail and cultural significance to the space by telling stories of the region’s rich history.

Even while artfully paying homage to Sámi and Norwegian heritage, Brasserie Árran embodies the elegance of contemporary Scandinavian design: the space is uncluttered and yet intricately adorned; sophisticated yet cosy and familiar. With gentle lighting, earthy tones and subtle scents helping to transmit a sense of warmth and hygge, the interior is sharply juxtaposed with the vessel’s dramatic backdrop and the cool, bright light of the midnight sun.

Providing a more exclusive and immersive dining experience, Trollfjord’s à-la-carte restaurant, Røst, at once celebrates Norway’s culinary excellence and mirrors its coastal setting. The venue’s carefully curated menu adds a contemporary twist to ingredients handpicked from the local environment, such as fresh seafood and seasonal vegetables. In a similar vein, YSA Design’s painstaking materials selection combines sophisticated modern touches with subdued natural tones reminiscent of coastal and underwater ecosystems. Seaweed not only features on diners’ plates but also influences the colour palette and décor: dark greens, organic textures and subtle patterns conjure images of a marine algae that grows abundantly along Scandinavia’s rocky shores.

At the heart of Røst is an open kitchen offering guests insight into the skill and creativity with which raw ingredients are transformed into culinary works of art. Opposite the galley are floor-to-ceiling windows granting unobscured views of either the Norwegian and Barents Sea or the country’s awe-inspiring coastline, depending on the direction of travel. When the curtains are drawn, the space is illuminated by copper pendant lamps whose metallic sheen enhances the refined contemporary aesthetic while offering a subtle nod to Hurtigruten’s nautical heritage.

Trollfjord’s combination of tradition, modernity and nature extends to the private suites. Here, the influence of Sámi artwork is evident in the furnishings and fittings. Materials including wool and wood emphasise the focus on sustainability, with earthy tones evoking the surrounding landscape and generating an elegant yet warm ambience. Again, decorative elements complement the overall aesthetic and bring to mind Norway’s seafaring culture and coastal landscapes.

Adjacent to the bedroom is a seating area complete with sofa, chairs and coffee table. If the comfortable furniture provides a homely feel, the unrestricted views from the bay windows remind guests that this is no ordinary setting for their morning coffee.

For Trollfjord, YSA Design has drawn on its considerable expertise to fulfil the expectations of the modern cruise audience; celebrate the culture and artistry of a local people; embody the sustainability values of the ship owner; and honour and revitalise an icon of Norwegian maritime history.

Elomatic chosen to improve the energy efficiency of Crown Seaways cruise ferry

The Denmark based transport and logistics company DFDS has selected Elomatic to develop and deliver its Elogrid solution on the Crown Seaways cruise ferry, to improve energy efficiency and reduce its carbon emissions. Crown Seaways ferry is a Ro-Ro passenger vessel which currently operates on the Denmark-Norway ferry route Copenhagen-Oslo.

DFDS will manage the installation of Elogrids during the annual drydocking at Fayard, which takes place in January 2024. Additionally, a specialist from Elomatic will supervise the operation on-site to ensure top-quality work and the smooth assembly of the complex structure.

The Elogrid tunnel thruster, which can be retrofitted onto a wide variety of vessels, reduces the additional resistance and, as a result, fuel consumption of ships. The solution will also help DFDS enhance the performance of its tunnel thrusters, resulting in better maneuverability. Additionally, it will reduce noise and vibrations throughout the entire vessel, meaning a better overall experience for passengers, a smoother journey, and an increased lifespan for onboard equipment.

Elogrid emphasizes how design expertise and resources are essential to tackling the decarbonization challenge. In general, the solution makes an immediate impact on the Carbon Intensity Indicator (CII) of vessels with fuel savings up to 4%, depending on the vessel design and speed. This also means a reduction in carbon dioxide emissions. Equipping tunnel thrusters with Elogrids typically repays itself within 6–18 months. Elogrid showcases Elomatic's profound expertise in flow modeling, serving as a prime illustration of our multi-disciplinary competencies across various sectors.

The partnership represents a major milestone in Elomatic’s strategic development. The Finnish engineering company is expanding its business by designing solutions that increase environmental and human wellbeing, whilst also improving the competitiveness of its customers.

“Our Elogrid solution significantly reduces water resistance and fuel consumption from ships, and demonstrates how even a small piece of equipment, developed using advanced modelling, can deliver a valuable impact on GHG emissions. It is an honor to have been chosen by DFDS S/A to support them on their energy efficiency and decarbonization initiatives, and we are confident that our partnership will continue to flourish in the near future," commented Guido Schulte, Sales Director for Elomatic’s Marine & Offshore Energy.

“We are committed to reducing our impact on the climate. In the short term, improving our existing fleet and making it pollute less and be more efficient is a focus area - even at smaller scales. To this end the Elogrid solution supports the efficiency of Crown Seaways and will reduce fuel consumption with around 1 % and hence support our green transition journey," says Moshe Poulsen, Superintendent and responsible for the vessel and the docking.

The Elomatic scope involves the design, manufacturing, and installation supervision of four grids for two tunnels on the Crown Seaways. This includes project management, concept design, performance analysis, basic design for authority approvals, when necessary, detailed design for manufacturing and assembling the Elogrids, procurement, overseeing the manufacturing process, coordinating the delivery of the Elogrids, and finally, providing on-site installation supervision.
