Shaft Generator Solution News

ABB secured orders from shipbuilders in China and South Korea to equip 18 and 12 liquified natural gas (LNG) carriers, respectively, with permanent magnet shaft generator technology. The ships are due for delivery between 2028 and 2030.ABB’s permanent magnet shaft generator system is aimed to boost fuel economy compared to solutions where power is provided by auxiliary engines. By avoiding starting up high-speed, fuel-intensive auxiliary engines during a voyage, ship operators can achieve significantly greater fuel efficiency.

WE Tech Solutions informs it has received an order from Sirius Shipping for a hybrid electric system for their new chemical tankers. For this order, WE Tech Solutions will provide the Solution Four for the tanker pair. This solution is based on a battery hybrid shaft generator solution. The solution makes it possible to run the main motor at variable speed, and the propulsion machinery can be operated at optimal duty points at all vessel speeds. The electrical network is also generated by the shaft generator. Therefore, there is no need to run auxiliary engines and generators when sailing.

WE Tech won additional orders in South Korea to supply its permanent magnet shaft generator solutions to four LPG Carriers to be built by Hyundai Mipo DockyardThe shaft generator solution comes with frequency drive technology and is designed to produce all required electrical power needed for the vessel over a wide main engine speed range, aimed to deliver substantial fuel savings and reduction of maintenance cost by reducing auxiliary generator operation. “Our solution is compact and fits perfectly to this type of gas carriers.

ABB said it has won an order from Korean shipbuilder Samsung Heavy Industries to equip two new 125,000 DWT shuttle tankers contracted to the world's largest offshore operator Statoil ASA. Ordered by petroleum and chemical tanker owner and operator AET and scheduled for delivery in 2019, the vessels will transport oil from the Statoil fields on the Norwegian and U.K. continental shelves to land-based terminals. The two twin-skeg specialist DP2 offshore loading shuttle tankers will feature a range of ABB’s power and automation solutions, including the power distribution system Onboard DC Grid.

WE Tech Solutions said it has received an order to deliver its permanent magnet shaft generator solution to two new 18,600 dwt chemical tankers with an option for another two. The tankers are built by China State Shipbuilding Corporation (CSSC) Chengxi Shipyard for the Swedish ship owner Ektank AB. WE Tech’s equipment delivery to Hudong Heavy Machinery Co., Ltd. will commence in October 2017. WE Tech’s solution is based on variable frequency drive technology (WE Drive) and the direct drive Permanent Magnet Shaft Generator. The solution allows the main engine to run at variable speed while the electrical network is generated by the Shaft Generator. Therefore, there is no need to run the auxiliary engines or generators when sailing.

Corvus Energy Inc. has announced  that it has been selected as the supplier of the lithium ion based energy storage system (ESS) for a new hybrid chemical tanker being built for Rederiet Stenersen AS of Norway. The chemical tanker will be the first vessel of its kind to utilize an ESS for propulsion. Corvus Energy will supply its next generation Orca Energy ESS solution to integrate with WE Tech Solutions’ propulsion system, which will deliver industry environmental performance for this new vessel.

Since it started publishing in 1939, Maritime Reporter & Engineering News has recognized excellence in ship construction. The Switch has been engaged in the maritime industry for only three and a half years, but it already has approximately 20 ships in its reference list, including the first, the 15,000 dwt M/T Ternsund  (featured on this month’s cover) owned by Terntank, which is a fourth generation company that in 1958 was a one ship company, and today is an operator of ten modern chemical/product tankers in the range from 8,000 to 15,000 dwt.

WE Tech Solutions (WE Tech), an energy efficiency solutions provider in the marine industry, and The Switch, a technology specialist of permanent magnet machines for advanced marine drive trains, have been chosen to deliver their permanent magnet shaft generator solution to Australian Toll Shipping for a series of two 12,000 dwt RORO vessels. The Sinotrans & CSC affiliated Jinling Shipyard in China will build the ships. Delivery of advanced equipment solution from WE Tech and The Switch will commence in August 2017.

WE Tech said it has received an order to deliver its permanent magnet shaft generator solutions to a series of four fuel efficient ROPAX ferries, with an option for another four. The vessels are to be built for the Swedish shipping company Stena RoRo at AVIC Weihai Shipyard Co., Ltd. in China. The four initial vessels will be operated by Stena Line within its route network in Northern Europe. “WE have developed the most energy efficient shaft generator solution to reduce the fuel consumption, operational costs and environmental footprint.

Energy efficiency solution provider WE Tech Solutions said it has received an order to deliver its direct-drive permanent magnet (PM) shaft generator solution to a series of two 17,500 DWT IMO class II chemical tankers, with an option for two more. The Switch, a technology specialist of megawatt-class PM machines for advanced marine drive trains, will deliver the PM shaft generators to be used in the solutions provided by WE Tech. The tankers will be built by the Chinese shipyard Taizhou Kouan Shipbuilding Co., Ltd. for Bergen-based Norwegian shipowner Rederiet Stenersen AS.

WE Tech Solutions (WE Tech), an energy efficiency solutions provider in the marine industry, has received an order to deliver its direct-drive permanent magnet shaft generator solution to two new 25,600 dwt dual-fueled handysize bulk carriers, with an option for two more. The Switch, a technology specialist of megawatt-class permanent magnet (PM) machines for advanced marine drive trains, will deliver the PM shaft generators to be used in the solutions provided by WE Tech. The vessels are owned by the Finnish ship owner ESL Shipping Ltd.…

Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special applications like elevators, cranes, hybrid vehicles or renewable energy, permanent magnet machines have already become the preferred technology. In the marine sector, they are now starting to be the main competitor to mainstream solutions. The development of permanent magnet materials has progressed quickly during the past few decades.

The Switch, a supplier of megawatt-class permanent magnet (PM) generator and full-power converter packages for wind power and other renewable energy applications, received another order to deliver two PM shaft generators to WE Tech Solutions of Finland. At the end of February 2015, WE Tech Solutions placed another order for two PMM 1000 M shaft generators from The Switch with the option for an additional two to be used in future WE Tech Solutions projects. WE Tech Solutions utilizes the PM machine both as generator and motor in their direct-drive permanent magnet shaft generator solution.
