Japan's boxship giant ONE is joining forces with Singapore's PSA to operate a terminal.

The joint venture at Pasir Panjang in Singapore will start operations in the first half of 2019.

It will offer four mega-containership berths with a combined capacity of 4m teu.

"The terminal will deliver reliable and efficient terminal services to ONE, securing best-in-class services for its fleet with this long term strategic partnership," the companies said.
