Voltaire Electric Yachts to launch sub-10m vessel


Voltaire Electric Yachts to launch sub-10m vessel

German/US startup Voltaire Electric Yachts has launched its 33 Sky model, a sub-10m vessel with a displacement of 4.7 tons, as pure electric and hybrid power continues to prove a growth area in the yacht industry.

Propulsion for the new craft will consist of two Torqeedo Deep Blue engines rated at 50kW each, with one in each of its catamaran hulls. The company noted this will afford a very tight circle.

The motors will be fed by a pair of 42.2kWh batteries sourced from BMW, originally intended for use in the i3 road car. These battery packs are increasingly popular with small electric boat builders, and Voltaire said they will come with a nine-year warranty.

Hybrid power revamp for offshore service vessel


Hybrid power revamp for offshore service vessel

When North Sea Giant was delivered to her Norwegian owner, North Sea Shipping, in 2011 she was the world’s most advanced offshore construction vessel. After an upgrade including the installation of triple-redundant battery banks, she can claim that title again, according to DNV GL, the maritime advisory specialists.

“She does all the high-end work, like spool installation and umbilical work,” says Sveinung Økland, operation manager at North Sea Shipping, about the company’s flagship. “She can install very large subsea components, and because of the large deck space she can perform two to three different tasks during a single deployment.” In 2011, the year of her delivery, the ship won Offshore Support Journal’s ‘Vessel of the Year’ award.

Norwegian electric cruise ship delivered


Norwegian electric cruise ship delivered

The Fjords cruise line has received its latest all-electric vessel, Legacy of The Fjords, which will join sister ships Vision of The Fjords and Future of The Fjords, cruising the west coast of Norway.

According to John Vonli, managing director of The Fjords, the delivery of the vessel marks an important milestone for the company. “Our mission has been to share the fjord experience with as many people as possible while reducing our impact on a fragile ecosystem,” he said.

Like Future of The Fjords, Legacy of The Fjords was designed and constructed by Norwegian shipyard Brødrene Aa.

Arriva Denmark receives five Damen zero-emissions ferries


Arriva Denmark receives five Damen zero-emissions ferries

The Damen Shipyards Group has delivered five of its 2306 E3 electric ferries to Arriva Denmark in Copenhagen where the company is operating the vessels on behalf of Danish public transportation agency Movia. The vessels are based on what Damen calls its ‘E3 philosophy’ – environmentally friendly, efficient in operation and economically viable.

Damen said that improving the efficiency and reducing the environmental impact of the vessels began at the earliest concept stages. For example, computational fluid dynamics (CFD) were applied to the hull design, minimizing resistance in the water, while extensive simulation was employed to optimize energy transfer between the batteries and motors.

Successful sea trials for solar yacht


Successful sea trials for solar yacht

The Solar Eclipse Aquanima 40 yacht, constructed by Azura Marine, has undergone a successful four-hour sea trial off the coast of Bali, Indonesia.

The boat’s builders stated that it achieved a maximum speed in excess of 8.5kts, but more importantly, was able to cruise at a steady 4.5kts, while consuming less power than was captured by its solar panel array. At this speed, it used 2kWh while the panels produced 8kWh. As a result, the vessel returned to its mooring with a fully charged battery. The company noted that throughout the sailing, navigation systems and domestic appliances were also consuming energy.

Affordable cathode materials breakthrough


Affordable cathode materials breakthrough

According to researchers at the University of Saskatchewan, the use of affordable materials in battery cathodes for large scale applications, including marine use, could soon become a reality.

“Cathodes represent 40% of the cost of the batteries that we are using in our phones right now. They are absolutely crucial to improve battery performance and reduce dependency on cobalt,” said Majid Rasool, lead author on a paper (PEDOT Encapsulated and Mechanochemically Engineered Silicate Nanocrystals for High Energy Density Cathodes) that investigates the use of iron and silicon for cathodes.

Both iron and silicon are abundant materials, hence why Rasool’s research team wanted to further investigate their potential in battery applications.

Penetration testing of a marine battery pack


Penetration testing of a marine battery pack

Marine energy storage supplier Sterling PBES has announced the completion of its most intense fire and safety testing to date.

The recent tests, the company said, validate the integrated liquid cooling, fire stop, and ventilation systems that come installed in its battery systems.

For the tests, a ferrous metal spike was driven through all plies of a cell in the battery, simulating catastrophic mechanical damage. Known as the most invasive and difficult test for a lithium battery, the nail penetration test simulates damage that may occur as a result of mishandling or impact from external forces.

Hybrid, boutique cruise ships commissioned


Hybrid, boutique cruise ships commissioned

A new generation of boutique cruise ships is set to emerge, with the luxury of a superyacht, the construction techniques and passenger experience of a cruise ship, and a close focus on the environment. So says hybrid and electric marine specialist Wärtsilä, which has signed a partnership agreement with architect and yacht designer Stefano Pastrovich for the design of innovative sustainable superyachts for the boutique cruise sector.

Precise details are still sparse, but Wärtsilä said the design will feature a fully integrated combination of hybrid propulsion and solar panels. The powertrain will be installed in a 60m-long catamaran with accommodation for up to 36 passengers.
