MAN Energy Solutions has won the order to supply 18 × MAN B&W 9S50ME-C9.6 TIER II-compliant main engines for Naples-based Grimaldi Groups series of nine new 7,800 lane-metre ro-ro vessels intended for operation in the Mediterranean Sea.
The engines will be built by MAN Energy Solutions’ two-stroke licensee – Hyundai Heavy Industries, while Jiangsu Jinling Shipyard will construct the vessels in Nanjing, China. Delivery of the first vessels is expected in 2020. MAN will also supply an MAN TCA66 turbocharger for each engine.
The new ro-ros are the first examples of a new series of hybrid vessels, which will use fuel oil during navigation and lithium batteries in harbour, thus guaranteeing ‘zero emissions in port’ while still satisfying energy requirements at berth. The batteries will be recharged during navigation through shaft generators.
Bjarne Foldager – Senior Vice President, Head of Two-Stroke Business at MAN Energy Solutions – said: “The bidding process was very competitive but, happily, a clear preference was expressed for our engines. Our technology will play a crucial role in this innovative hybrid propulsion system that really points the way for shipping in the future. Along with MAN PrimeServ, our after-sales business, we thank the Grimaldi Group for its custom and look forward to powering these unique vessels.”
The new ro-ros are part of what Grimaldi calls its “Green 5th Generation” that represents a significant expansion and modernisation of the company’s fleet. They will have a length of 238m, a beam of 34m and a gross tonnage of 64,000 with a loading capacity double that of the Neapolitan group’s current, largest such vessel and triple that of its previous generation of ro-ros. The MAN B&W ME-C engines – as part of the hybrid propulsion set-up – will enable a 100% increase in efficiency when measured in terms of consumption/tonne of freight transported, compared to Grimaldi’s existing vessels.
