4,700 linear meters of rolling freight, 2,500 automotive equivalent units (CEU) and 2,000 TEU would be able to carry the new G5-class ships.

The ships will be an evolution of the previous G4 class, with a length of 250 meters, a beam of 38 meters and a deadweight of 45,684 tonnes, designed by the same shipyard and delivered to the Grimaldi group between 2014 and 2015.

The new units will have the same capacity for rolling freight compared to the previous G4-class vessels, while container capacity will double. Grimaldi said the concept is the product of a careful analysis of the group's and its clients' needs.

The NOx levels imposed by the Tier III regulation will be met by both the main engine and the auxiliary diesel generators, whereas the integrated propulsion system between the rudder and the propeller will mitigate vortex losses, maximize propulsive performance and reduce fuel consumption.

The vessels will be equipped for the supply of electricity to the shore at the berth.

In addition, the installation of variable frequency drive devices will reduce the electrical consumption of on-board machinery, while the application of advanced low friction coatings, according to Grimaldi, will reduce hull resistance.

Finally, combined exhaust gas cleaning systems for the elimination of sulphur and particulate emissions will be equipped for the boat.

Compared with other Grimaldi multipurpose ro/ro ships, Grimaldi says, the G5-class units will allow a reduction of CO2 emissions per tonne transported of up to 43 percent.

It is estimated that the six ships will be delivered between the first months of 2023 and the end of 2024.
