WE Tech has received a new order from Hyundai Heavy Industries and Hyundai Samho Heavy Industries Shipyard to deliver direct drive permanent magnet shaft generators to eight new LNG carriers destined for long-term charter to Shell LNG. The order includes an option for six further LNG carriers.
The eight 174,000 cbm newbuilds have been ordered by Knutsen OAS Shipping, J.P. Morgan Asset Management and Korea Line Corporation.
The order is the third from a South Korean shipbuilder for WE Tech’s variable speed shaft generator solution since 2019, but the first for an LNG carrier. The preceding two orders were for LPG carriers.
The order comprises variable speed frequency drives, two sets of direct drive permanent magnet shaft generators and a dedicated Power Management System (DPMS). In PTO mode, the vessels’ electrical power will be supplied from the shaft generator alone via the WE Drive meaning the auxiliary generators can be stopped. Utilising the main engine for electrical power generation rather than the gensets results in fuel efficiencies and emissions reductions.
“Our state-of-the-art variable frequency drive technology together with permanent magnet generators which have the markets highest efficiency over the full speed and power range can fully satisfy gas carriers’ needs”, said Peter Lindstrom, Sales Manager of WE Tech Solutions, “with our solution, the energy efficiency of the machinery reaches unprecedented levels.”
The equipment is scheduled to be delivered to the shipyard from February 2021.
