International energy efficiency solution provider WE Tech Solutions has received an order to deliver its Permanent Magnet Shaft Generator solution to two new 18600 dwt chemical tankers with an option for another two.
When the tankers are in the harbour, the solution allows the use of cleaner shore power. This versatile solution will save tons of fuel and reduce emissions both at sea and harbour environment.
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 this year.
'The solution from WE Tech is important for us to build the next generation chemical tankers, in terms of energy efficiency and sustainability. These vessels will meet all known future demands from governments, the industry and from our customers,' says Jörgen Johnsson, managing director of Ektank AB.
The solution is based on variable frequency drive technology and the direct drive Permanent Magnet Shaft Generator. It allows the main engine to run at variable speed while the electrical network is generated by the Shaft Generator.
As a result, there is no need to run the auxilliary engines or generators when sailing. This creates tons of fuel savings and reduces operational and maintenance costs. In the event that the main engine is out of operation, the solution uses the shaft generator as motor – a reliable and cost-effective Auxiliary Propulsion Drive (APD) to ensure the vessels’ safe return to port.
This solution also brings an efficient method to distribute power to bow thrusters and the cargo handling system of the tankers. The method is to connect these large electrical consumers’ inverter units to the common DC link of WE DriveTM. 'We… strongly believe that our innovative technology and reliable solutions are the future of the marine industry,' says Martin Andtfolk, sales manager of WE Tech.
