Rolls-Royce Unveils New Podded Propulsion Range

Rolls-Royce has launched a new range of smaller, more compact podded propulsion systems: the ELegance pods – one with an open propeller, the other ducted.Per Nahnfeldt, General Manager Product – Electric Propulsion, Rolls-Royce, said, “For many years we have recognized the gap in the propulsion market for smaller pods, including ice-class, in the 1.5MW to 7MW power range. These new pods – based on our Permanent Magnet technology – complement our broad product portfolio and sit well with our range of frequency drives and electrical systems.

‘World’s Greenest Cruise Ship’ Construction Underway

Hurtigruten CEO Daniel Skjeldam pressed the button to officially kick off the construction of hybrid expedition cruise ship MS Roald Amundsen – “the greenest cruise ship the world has ever seen,” according to the ship owner. The new ship is the first of a new generation that will change expedition travel forever, Skjeldam said during the ceremony at Kleven Yards on the western coast of Norway. When launched in 2018, MS Roald Amundsen will be the world’s first expedition cruise ship powered by hybrid battery technology.

Polar Cruise Ships to Feature Rolls-Royce Green Tech

Norwegian explorer cruise line Hurtigruten is to build two new expedition ships using a new and environmentally sustainable hybrid technology from Rolls-Royce making fully electric propulsion on a passenger ship possible. The Rolls-Royce designed MS Roald Amundsen and MS Fridtjof Nansen, about to be constructed at Kleven Yard in Norway, will be packed with innovative Rolls-Royce technology. In addition to the hybrid power solution, the vessels will have the latest automation and control systems…

The Switch Acquires Wärtsilä Drives’ Products

The Switch, a technology specialist of advanced drive trains, announced its acquisition of Wärtsilä’s marine drives business that encompasses specialized megawatt-class power drives targeting marine applications. The Yaskawa-backed investment gives The Switch a stronger foothold in its growing marine business area. Together, The Switch and the Norway-based marine drives business aim to benefit from a number of inherent added-value synergies, including a stronger machine and drive package offering, a broader product range and a wider market access.

Norwegian Orders Rolls-Royce Propulsion Upgrade

Norwegian Cruise Line has selected a Rolls-Royce permanent magnet tunnel thruster to upgrade the propulsion package onboard cruise vessel Norwegian Epic. According to Rolls-Royce, the permanent magnet tunnel thruster offers numerous advantages over traditional tunnel thrusters including reduction in noise and vibration, an increase in power output of around 25% from the same size propeller, and is removable underwater eliminating the need for dry docking. The permanent magnet tunnel thruster design concept comprises a permanent magnet motor in a rim, which drives the propeller in the centre.

"The Switch" Passes Bench Test

The Switch, a specialist of megawatt-class permanent magnet (PM) machines and frequency converter packages for advanced wind and marine drive trains, has successfully tested its PM shaft generator in a rigorous bench test in Vaasa. The first pair in an order of four PM shaft generators is part of a complete system being delivered by WE Tech Solutions of Finland to Wallenius Lines of Sweden. The PMM 1000 direct-drive marine shaft generator certified by Lloyds marks the first of its kind to take advantage of PM technology, allowing ships to gain greater efficiency over the entire speed range.

Permanent Magnet Technology for Maritime Propulsion

Multipurpose vessels, especially those that operate primarily at part loads, have been facing pressure when it comes to making money in today’s business environment. Returning to times of big profit margins will not happen soon without finding a radically different approach. Using permanent magnet technology for electric propulsion systems is a bold and proven way to save ship owners money due to lower fuel costs, less maintenance and fewer failures. As cost pressures mount and environmental regulations become more stringent, the need for a novel and smarter approach is ever more apparent.

The Switch Inks Deal with WE Tech

The Switch, a supplier of megawatt-class permanent magnet generators, motors and frequency converters, received an order from WE Tech Solutions Oy of Vaasa, Finland for four permanent magnet (PM) shaft generators. Coupled together with WE Tech’s WE Drive, these PM shaft generators represent game-changing technology for merchant ships to allow them to significantly cut back on operating costs when powering their onboard electric networks. The deliveries will start later this year.

The Switch Lands First Marine PM Shaft Generator Order

The Switch, a leading supplier of megawatt-class permanent magnet (PM) generators, motors and frequency converters, say they have signed an agreement for the delivery of four direct-drive 1.5 MW PM shaft generators to WE Tech Solutions Oy of Vaasa, Finland, who will couple them their WE Drive system for marine use. According to the manufacturers, the order strengthens the position of The Switch as it uses its proven track record of applying PM generator technology successfully in the wind power industry now to a range of marine applications.
