The company, booked in June, sees the company also providing project management and commissioning of the systems.

The ships are being built at Oshima Shipbuilding Co., Ltd. in Japan for Tokyo based NYK Bulk & Projects Carriers Ltd. (NYK BP), a wholly owned subsidiary of Nippon Yusen Kabushiki Kaisha (NYK).

These are the first vessels owned or chartered by NYK Group having exhaust gas cleaning systems installed. By fitting the Wärtsilä system, the ships will be compliant with the IMO's SOx regulations, which come into force in 2020.

The Wärtsilä equipment is scheduled for delivery to the yard commencing in July 2018. The first vessel is due to be delivered to NYK in the 4th quarter of 2018, and the second in the 1st quarter 2019.
