KNUD E. HANSEN DESIGNS THE 5TH GENERATION OF RO-RO VESSELS FOR GRIMALDI. WITH HYBRID PROPULSION (WITH BATTERIES THAT CAN BE RECHARGED WITH SOLAR ENERGY) AND HELMET AIR LUBRICATION SYSTEM.
At the beginning of this month of May, the Grimaldi Group signed the agreement to build six new Ro-Ro vessels within its expansion and modernization program of its fleet. Valued at more than 400 M $.
They will be built in the Nanjing Jinling Chinese shipyard and will be delivered in 2020. They will be 238 m long, 34 m wide, 64,000 gt, 7,800 m load (equivalent to 500 trucks). This cargo capacity is double that of the largest ship that currently operates this company. At the same speed they will consume the same amount of fuel, which means a 100% increase in efficiency when measured in terms of consumption / t of cargo transported.
The design of these new buildings, called GG5G (Grimaldi Green 5th Generation), will be carried out by the Danish firm Knud E. Hansen in collaboration with the Technical and Energy Saving Department of the Grimaldi Group.
They will be hybrid Ro-Ro vessels, which will burn fossil fuels during navigation and electricity while they remain in port, thanks to the fact that they will be equipped with lithium batteries that will be recharged during the periods of solar navigation (600 m 2 of solar panels will be provided by these vessels) and / or generators. Another of the technical innovations to be highlighted in these new constructions is the air lubrication system under the keel to reduce friction and aerodynamic drag and consequently the reduction of emissions and fuel consumption.
The helmet will be covered with non-toxic silicone paints characterized by their low surface roughness and will not release substances into the environment. Regarding sulfur emissions, special systems installed on board will allow the sulfur emitted when mixed with salt to convert it into gypsum for later reuse or discarding in nature. Three of these six new vessels will be directly operated by Grimaldi in the Mediterranean. The other three, ice class, will be for the Finnlines Group (of which Grimaldi shares) by the Baltic Sea.
