Korea's Hyundai Merchant Marine (HMM) is planning to double its capacity by 2022 as it plots its "resurgence".

CEO Yoo Chang-keun told staff in his new year message: "We have gone through a long tunnel, and see the light of hope at last."

Bouncing back from its restructuring in 2016, the company is now considering ways to increase the fleet size, "including the launching of mega-containerships as we deem the environmental regulations in 2020 as a golden opportunity for our resurgence," Yoo said.
