ABB is to deliver an integrated scope of solutions with permanent magnet shaft generators at its core for twelve 210,000 dwt bulk carriers owned by the Bermuda-based Himalaya Shipping. The technology will improve the energy efficiency of the vessels by up to 4% while saving about 20% of space on board compared to a conventional solution. In addition, higher power density enabled by ABB’s solution allows reducing fuel consumption and emissions.
ABB’s equipment package for Himilaya Shipping’s ultra large bulk carriers will feature innovative shaft generators with a Power-Take-Off (PTO) solution, comprising new drive systems and permanent magnet technology. ABB’s full scope of supply for the Himalaya Shipping vessels also includes low-voltage drives and transformers, as well as engineering, project management and commissioning services.
The ships’ energy systems align with goals set out in the IMO Energy Efficiency Design Index (EEDI) and Carbon Intensity Index (CII).
Shaft generator performance gains exploit the inclusion of permanent magnet technology and new ACS880 single drive systems from ABB, the drive system delivering greater responsiveness for the changing power needs of a bulk carrier depending on the speed, bulk freight weight, and electrical load changing.
“ABB’s latest series of shaft generators support our initiatives to ensure optimised ship efficiency, reduce CO2 / NOx emissions and deliver maximum performance using less power in a package that is compact, robust and easy to maintain,” said Jan Andersson from SeaQuest, Himalaya Shipping consultant.
“We are honoured to build these innovative dual-fuel bulk carriers,” said Qiaohua Dong, Deputy Director of Ship Design Institute of Jiangsu New Times Shipbuilding. “With more strict emissions regulations and requirements, our shipyard should also adapt to new technologies and solutions. It is the first time for us to install ABB’s latest shaft generator system. By utilizing this energy-efficient system, it will also help us to develop the capability of building an energy-efficient and environmentally friendly future.”
“This contract marks a significant milestone for our new generation of permanent magnet shaft generator-based solutions, with improved energy efficiency,” said Michael D. Christensen, Global Segment Manager Dry Cargo, ABB Marine & Ports. “The solution offers a range of benefits to help shipowners and operators enhance efficiency and reduce emissions without the need for additional investments compared to a standard synchronous excitation machine. Furthermore, the ABB ACS880 drive system ensures supreme performance and the very best uptime in class.”
