MAN Energy Solutions has announced an order to supply 18 MAN B&W 9S50ME-C9.6 TIER II-compliant main engines for nine 7,800 lane-metre ro-ro vessels for Grimaldi, intended for operation in the Mediterranean Sea.

Grimaldi Group is based in Naples, Italy, and is said to be a leading operator within the ro-ro segment. MAN Energy Solutions’ two-stroke licensee Hyundai Heavy Industries (Engine & Machinery Business Unit) will build the engines in Korea, while Jiangsu Jinling Shipyard will construct the vessels in Nanjing, China. Delivery of the first vessels is expected from 2020. MAN will also supply a TCA66 turbocharger for each engine.

The new ro-ros are claimed to be the first examples of a new series of hybrid vessels, which will use fuel oil during navigation and lithium mega-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 adding the so-called peak shaving system.

Bjarne Foldager (pictured), Senior VP, Head of Two-Stroke Business, 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 fifth Generation' that represents a significant expansion and modernisation of the company’s fleet. They will have a length of 238m, beam of 34m and a gross tonnage of 64,000gt with a loading capacity double that of the group’s current largest such vessel and triple that of its previous generation of ro-ro ships. 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/ton of freight transported, compared to Grimaldi’s existing vessels.
