Hapag-Lloyd and Seaspan Corporation have partnered up to retrofit and convert five 10,100 TEU container ships powered by conventional MAN S90 engines to dual-fuel engines capable of operating on methanol. Following the engine retrofit, the vessels will continue to be on long-term charter from Seaspan to Hapag-Lloyd.

Dr. Maximilan Rothkopf, Hapag-Lloyd’s COO, states: ‘The methanol retrofit project is a further step in our ambitious sustainability agenda, which aims to achieve the decarbonisation of the entire fleet by 2045. By enabling these vessels to use green methanol as of 2026, we will meet our customers’ growing demand for green transportation solutions.’

‘Collaboration between strong and like-minded partners, Hapag-Lloyd and Seaspan, drives innovation. Retrofitting must be an integral part of the strategy if the container shipping industry wants to deliver on its decarbonisation targets,’ adds Torsten Holst Pedersen, COO of Seaspan.

To achieve its strategic decarbonisation goal, Hapag-Lloyd’s investments are not only focused on newbuildings or retrofits (dual-fuel propulsion) and the optimisation of the efficiency of its existing fleet (Fleet Upgrade Programme), but also on covering the exploration and sourcing of green fuels. Green methanol is thereby emerging as one of the low emission fuels of the future.

USD 120 million investment

The vessels scheduled for retrofits are the Seaspan Amazon, Seaspan Ganges, Seaspan Thames, Seaspan Yangtze and Seaspan Zambezi. The retrofit is expected to take approximately eighty to ninety days per vessel starting in the first quarter of 2026. The total investment is estimated at around USD 120 million for the five units.
