    Elomatic collaborates with NYK Group to create emission-free cargo ship


    Elomatic has partnered with Japanese shipowner NYK Group and NTK’s technology arm MTI to create the concept design for a futuristic emission-free pure car and truck carrier (PCTC), – the “NYK SUPER ECO SHIP 2050”. Compared to current vessels, the NYK SUPER ECO SHIP 2050 will reduce CO2 emissions by 100%. The energy-efficient vessel will also reduce energy derived from bunker fuels by approx. 70%.


    The concept design was unveiled by NYK Group in mid-November. Elomatic was responsible for the concept creation and visualisation. The development of NYK SUPER ECO SHIP 2050 is part of NYK Group’s “Staying Ahead 2022 with Digitalization and Green” medium term management plan.


    The NYK SUPER ECO SHIP 2050 is a follow-up from a project done in 2009 by the same parties, which culminated in the award-winning design of a container vessel for 2030, the NYK SUPER ECO SHIP 2030. Japan, Finland and its Scandinavian neighbours have long-standing innovation traditions in the maritime sector and NYK SUPER ECO SHIP 2050 is another step in maintaining this leadership position. All partners involved in the project have a vision of a carbon-free world. 


    The resistance of the vessel was reduced by 35% by remodelling the hull to decrease water friction, by reducing the weight of the hull, and by minimising air resistance. The improvements where validated with CDF calculations. Further improvements were made by introducing fuel cells for electric propulsion, relying on other highly efficient propulsion devices, and the generation of renewable energy on board the vessel.


    Energy demand reduced by almost 70%

    The energy demand of the vessel was cut by approx. 70% by eliminating energy and operational waste. The minimised energy demand enables truly emission-free operation. Instead of fossil fuels, the ship is powered by hydrogen produced from renewable energy sources. Some other futuristic elements in the concept include lightweight bionic design found in nature, the use of 3D printing for building materials, a digital twin of the vessel, and flapping foils inspired by dolphins to replace less efficient traditional propellers.


    “We are honoured that NYK Group have continued trusting in our ability to provide technical and technological solutions for a greener future. One of our core goals is assist our customers in their struggle against the most significant challenges of our time. The greatest of these are environmental wellbeing, resource sufficiency and questions related to technology upheaval,” says Elomatic CEO Patrik Rautaheimo.

    Indian Register of Shipping (IRClass) triples the solar plant capacity at its head office


    Indian Register of Shipping (IRClass), a leading classification society, has made a further investment in renewable energy initiatives at its head office in Mumbai.


    Following on from the adoption of two green initiatives at IRClass HQ last year, the classification society has now increased its solar power capacity from the existing 72 kW to 233 kW – tripling the installed capacity.


    The system is based on a unique OPEX/ BOOT model with an asset lifespan of 25 years. In environmental terms one-year operation of such a system is the equivalent of planting 450 trees saving CO2 emissions of approx. 128500 kgs.


    In 2017, IRClass introduced an in-house solar rooftop plant as well as a reed bed system to continuously improve the environmental sustainability of operations at its head office.


    Mr. B V Nargundkar, Sr. VP & Head Administration, HR & Legal said today ‘IRClass is committed to enhancing its efforts to build a clean and green workplace for its staff and the local environment. We will continue to take initiatives towards increased use of renewable energy in our offices’.

    Rolls-Royce receives Approval in Principle for hybrid tug propulsion system


    Rolls-Royce received Approval in Principle (AIP) from classification organization ABS for its novel hybrid propulsion system for tractor tugs.


    The AIP was granted following an evaluation of the world’s first hybrid tug, a unique vessel designed by Jensen Maritime and which Nichols Brothers Boat Builders will deliver to Baydelta Maritime LLC in February 2019. The vessel will be the first tug boat installed with the Rolls-Royce hybrid propulsion system.


    ABS considers the Rolls-Royce hybrid system is, in principle, compliant with ABS Rules for Building and Classing Steel Vessels Under 90m (2018); ABS Advisory on Hybrid Electric Power Systems (2017); and ABS Guidance Notes on Review and Approval of Novel Concepts.


    Griff Lane, Rolls-Royce SVP Commercial Marine, Americas, said: “Our long-standing partnership with Baydelta Maritime and close cooperation with Jensen Maritime, Nichols Brothers and ABS has paved the way for an innovative, environmentally-friendly hybrid tug capable of safe and reliable operation and maximum bollard pull. The Rolls-Royce hybrid system enhances the tug’s escort capability, providing unsurpassed assist support to the ultra-large containerships that operate from US West Coast ports.”


    The Rolls-Royce Hybrid Propulsion System consists of Power Take-In (PTI), electric motors, and main propulsion engines connected to Rolls-Royce azimuth thrusters, allowing vessel to operate in either a diesel-mechanical, diesel-electric or boost mode configuration.


    “The key benefit of a hybrid configuration is that it reduces the power requirement,” said Lane. “Typically, a tug the size of the Baydelta vessel would need a power output 2500kW. The hybrid arrangement allows operators to achieve the required bollard pull from a smaller engine. It provides greater operational flexibility which allows for the system to provide improved fuel efficiency, redundancy, and reduced emissions.”


    “ABS is an industry leader in providing guidance to support safe development and deployment of hybrid power across the maritime sector.” said Derek Novak, ABS Senior Vice President Technology and Engineering. “We are pleased to work with innovative companies like Rolls-Royce, Baydelta Maritime, Jensen Maritime, and Nichols Brothers aiding the development of environmentally friendly technologies,”


    Atle David Monsen, Rolls-Royce VP Sales, Integrated Ship Systems added: “Deep system integration between engines, electrical equipment, thrusters and automation systems is crucial in hybrid vessels. The Approval in Principle from ABS helps confirm the safety and functionality of the Rolls-Royce hybrid tug concept. With Rolls-Royce as a system integrator the risk and complexity for both owner and yard is significantly reduced.”


    Rolls-Royce will supply all electric motors, shaft generators and a power management and control system. The hybrid arrangement provides power to US255 azimuth thrusters with ducted fixed pitch propellers that can be rotated 360 degrees around the vertical axis. This arrangement optimises omni-directional thrust and manoeuvrability as well as providing improved crash stop capability.

    Rolls-Royce wins Propulsion contract for nine Ro-Ro vessels


    Rolls-Royce Commercial Marine has won a significant contract to deliver the propulsion system to nine vessels to be built by Nanjing Jinling Shipyard Co in China for the Italian Grimaldi Group.


    The nine 238 meter long vessels are so called Ro-Ro vessels (Roll-on-Roll-off) designed to transport over 7,800 linear meters of rolling units, equivalent to about 500 trailers. They are named the Grimaldi Green 5th Generation, and will be hybrid powered by combining use of traditional fossil fuels during operation and battery power when in port. The vessels are being designed by Knud E. Hansen in Denmark.


    Ottar Ristesund, Rolls-Royce, SVP Propulsion Sales – Commercial Marine, said: “We are very much looking forward to working together with the customer to deliver this large order in a timely manner. So far the cooperation between the yard, the owner and our involved team members in China, Italy and the Nordic countries has been excellent, a pivotal factor in both securing the deal and for the future success of the project.”


    The delivery from Rolls-Royce includes steering gears and the Promas system, which integrates the propeller and the rudder into a single system to optimise hydrodynamic efficiency. A special hubcap is fitted to the propeller and streamlines the flow onto a bulb that is added to the rudder, effectively reducing flow separation immediately after the propeller. The result is an increase in propeller thrust as previously wasted energy is recovered from the flow. The addition of the bulb on the rudder also streamlines the flow aft of the rudder, further reducing drag.


    Promas is a well proven a product developed and tested at the Rolls-Royce facility in Kristinehamn in Sweden. While the steering gear is produced at the company’s facility in Brattvåg, Norway.


    The contract value to Rolls-Royce Commercial Marine is close to 300 MNOK. Delivery of the propulsion products are scheduled from 2019 and onwards to the completion of the last vessel in the series in 2021.

    Wärtsilä achieves notable advances in automated shipping with latest successful tests


    The technology group Wärtsilä has successfully completed a further round of test procedures of its automated dock-to-dock solution. In an unprecedented operation, in the presence of the Norwegian Maritime Authority (NMA), the system was further tested on the ferry ‘Folgefonn’, this time for full dock-to-dock capability, with the autonomous operation being utilised uninterrupted for the entire route, visiting all three ports serviced by the ship.


    “This represents a huge step forward in validating automated shipping solutions, and an important progression within our Smart Marine programme. This emphasises once again Wärtsilä’s recognised position as the global technology leader in marine innovations. We continue to lead the way in developing the ‘intelligent’ products and systems needed to move the marine industry towards a new era of super-high efficiency, safety, and environmental sustainability,” says Joonas Makkonen, Vice President, Voyage Solutions, Wärtsilä.


    The success of these latest tests cannot be underestimated. Once the operator selected the next destination berth, the operation was started by simply selecting “Sail”, which authorises the autonomous controller to take control of the vessel. The ferry was able to leave the dock, manoeuvre out of the harbour, sail to the next port of call, manoeuvre through the harbour entrance, and dock alongside the terminal – all without human intervention. It is believed to be the first ever attempt at fully automated dock-to-dock operation, in complete hands-off mode, for a vessel of this size.


    Navigation of the vessel is controlled through the use of a series of tracks and waypoints, which guide the ship to the next destination. The autonomous controller, which is based on Wärtsilä’s existing Dynamic Positioning system, controls the vessel’s speed, position on the pre-defined track, and heading. GNSS is used as the primary sensor, while a Wärtsilä Guidance Marine CyScan AS is being tested as a secondary position sensor for the approach to the berth.


    “We were on site for three days as witnesses to these tests; the first full scale demonstration towards an autonomous operation of a vessel that we have seen. It was, to say the least, very impressive. There is no doubt that such technology can eventually increase the safety and overall efficiency of the docking and undocking operations for ships. Of course, further development work is still ongoing, but I am impressed by how stable the system already is at this stage,” says Nils Haktor Bua, Project Manager at NMA.


    The 85 metres long ‘Folgefonn’ is owned by Norwegian ferry operator Norled. It was used also for the initial testing of the Wärtsilä autodocking solution, which took place in the early part of 2018. The vessel is also equipped with hybrid propulsion with wireless shore connection capable of fully electric operation, and features numerous other Wärtsilä innovations, including its wireless inductive battery charging solution and energy storage systems.


    “We are pleased to cooperate with Wärtsilä in this exciting project. A fully autonomous dock-to-dock solution will provide us with considerable value-adding benefits in terms of better efficiency, greater safety, lower fuel consumption and, therefore, reduced exhaust emissions. We see the Wärtsilä solution as being a key support to the crew, enabling them to operate the vessel as effectively as possible,” added Sigbjørn Myrvang, Technical Manager at Norled.


    Innovation Norway, an investment fund, has provided grants to both Wärtsilä and Norled for the testing of the auto-docking technology.

    Rolls-Royce unveils new waterjet range for workboat sector


    Rolls-Royce unveiled a new range of Kamewa waterjets today at the International Workboat Show, in New Orleans, USA.


    Taking more than three-years research and development, the new A5 Series improves upon the popular FF range of Rolls-Royce Kamewa waterjets by providing greater thrust from a waterjet with a more compact inboard footprint.


    Geared towards smaller boats and craft up to 25m in length, the A5 series is manufactured from high-grade marine aluminium and available in seven sizes with power outputs between 100kW and 1230kW. The A5 will eventually replace the FF range and size 29 will be first to hit the market.


    Speaking at the A5’s official unveiling, Fredrik Appel, Rolls-Royce General Manager Product – Waterjets, said: “The A5 is a completely new product, which is developed on the same design principles as our renowned steel series. All aspects of the product are improved compared to our existing FF series. Overall pump efficiency is improved by 3%. Steering and reversing efficiency is improved by 8% and bollard pull is improved by 13%”.


    “Besides the propulsion improvements, we have reworked the mechanical design to gain the benefits of a harmonized series, and by this gaining more accurate performance predictions. We have listened to our customers asking for a smaller inboard footprint and adapted the design to meet this by reducing the space by 20%. However, we have also maintained an inlet waterway to accommodate the propulsion improvements.”


    Extensive Computational Fluid Dynamics (CFD) analysis and model scale testing at the company’s hydrodynamic research facility in Kristinehamn, Sweden, was involved in the A5’s development. Additionally, by incorporating elements from the proven S4 and S3/CA steel series of waterjets, Rolls-Royce has improved the axial-flow type waterjet to produce a smaller waterjet without the need for a comparative reduction in the power requirement.


    “Working with our colleagues in Finland and Sweden, we have produced an axial flow waterjet that has a smaller footprint yet delivers improved steering and reversing efficiency, higher thrust at low to medium speeds and increased bollard pull performance.”


    Shival Sapre, Rolls-Royce General Manager Sales, Americas, added: “The Rolls-Royce Kamewa A5 Series offers the best price per performance for vessels operating at speeds between 25 and 40 knots. The Kamewa A5 is a cost-effective waterjet solution for workboats, motor yachts, smaller passenger vessels, patrol boats and other high-speed, shallow draught vessels.


    Rolls-Royce has successfully carried out in-service trials of the new waterjet onboard its own demonstration vessel – a crew transfer/harbour patrol vessel operating in Kokola, Finland.


    An A29-5 unit, the first product in the series to be released, is exhibited at the International Work Boat Show on the Rolls-Royce booth 2501.
