South Korea's HMM has moved staff into its new fleet control centre in Busan after it took delivery of the world's largest containerships.
The company said the facility is based at its research and development base in the city.
The centre will monitor and control the operation of HMM’s modern fleet, including 12 24,000-teu vessels and eight 16,000-teu ships.
The biggest containerships in the series have now all been handed over, while the smaller vessels will join the fleet in the second quarter of 2021.
