Himalaya Shipping to fit 12 bulkers with ABB shaft generator solutions

Himalaya Shipping has chosen to fit twelve of its ultra large bulk carriers with shaft generators with a Power-Take-Off (PTO) solution from ABB.

The shaft generator solutions will comprise new drive systems and permanent magnet technology, improving the energy efficiency of these vessels by up to four per cent while enhancing operational flexibility.

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 International Maritime Organization (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.

The possibility to choose the most efficient operational option from several alternatives allows reducing fuel costs by 3-4 per cent, while the footprint of the equipment package is approximately 20 per cent smaller compared to equivalent units featuring synchronous excitation machines. In addition, higher power density enabled by ABB’s solution allows reducing fuel consumption and emissions.

“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 utilising this energy-efficient system, it will also help us to develop the capability of building an energy-efficient and environmentally friendly future.”
