Marubeni Corp is to trial wind-assisted propulsion on one of its panamax bulkers under a deal with Spanish company bound4blue.

The 84,860-dwt Crimson Kingdom (built 2016) will be fitted with four 26-metre-high suction sails in the first such trial by the Japanese trading house giant.

The vessel will be retrofitted in 2023/24 with what is expected to be the largest suction sail installation in the world and the first panamax bulker using suction sails.
