According to the Organization for Economic Cooperation and Development (OECD), ocean shipping carries around 90% of traded goods, with volumes set to triple by 2050. At the same time, shipping accounts for almost 3% of total greenhouse gas (GHG) emissions, which will also triple by 2050 if the industry takes no countermeasures.
It is well established that using the main propulsion engine to produce power for a vessel’s electrical network is generally more efficient than running auxiliary gensets. This is accomplished by mounting a generator directly onto the propulsion shaft. To take energy efficiency to the next step the conventional rotor winding arrangements of the shaft generator can be replaced with permanent magnets.
Permanent magnet (PM) shaft generators are smaller, lighter, and easy to install, making them a highly appealing technology for shipbuilders and system integrators. They can be used to equip new vessels to a higher standard or upgrade existing vessels with reasonable time and labour costs, while operators benefit from ongoing savings on fuel and maintenance.The improved energy efficiency, flexibility and lower emissions.
