NYK Line has struck a 50-ship deal with Chinese repair yards to fit ballast water treatment systems and scrubbers to some of its dry bulk fleet.

The move comes as Japan’s big three shipping companies step up efforts to comply with IMO 2020.

It appears NYK, which controls 750 ships, is leveraging its considerable purchasing power to strike a price-competitive, all-­inclusive bulker deal with the ­unnamed Chinese yards at a time when dry-dock space is scarce.
