MAN Energy Solutions has won the order for 4 × dual-fuel MAN B&W 6S60ME-GI (gas injection) engines in connection with the construction of two hybrid, 8,000 lane-metre, ro-ro vessels for CLdN, the Luxembourg-based shipping group.
The two newbuildings will have a hybrid propulsion system with each featuring 2 × ME-GI engines (2 × 11 MW) along with MAN Energy Solutions’ proprietary exhaust gas recirculation emissions system. Both 234-metre vessels are scheduled for delivery in the first half of 2025.
They will also be supplied with 2 × 6MW electric propulsion motors that will enable the ships to maintain a service speed of 16 – 17 knots in full-electric mode. Additionally, each ro-ro will have 2 × 678 kWh batteries, and while the vessels will still have emissions during in/out port manoeuvring, shore connection is provided and will offer zero emissions in port. Furthermore, each engine will be equipped with a PTO, while the vessels’ respective shafts will come equipped with a clutch ready to deliver a PTH of 6MW.

The fifth and sixth vessels in the CLdN’s preceding LNG-ready Laureline series were powered by seven-cylinder S50ME-C-GI main movers.
CLdN reports that, compared with its largest vessels currently in service, the new ships – the largest investment in its history – will further reduce carbon intensity by 40% while being NOx Tier III-compliant.
CldN has gained experience with dual-fuel propulsion, having taken delivery of a quartet of LNG-ready ro-ro vessels from Hyundai Mipo Dockyard, and more recently ordered a pair of dual-fuel ro-ros.
Gary Walker, COO Shipping, CLdN said: “In 2021, we were announced as top performer amongst our ro-ro shipping peers in Northwest Europe for CO2 emissions per tonne of freight carried. By investing in technologically advanced ships and terminals, we enable our customers to improve their carbon footprint and support them at the same time in making their supply chains more efficient and robust. At CLdN, we pride ourselves on minimising our environmental footprint and hybrid propulsion is an exciting step for us. Picking ME-GI engines for these vessels was a natural choice as they have become the industry standard for LNG-fuelled, low-speed prime movers due to their low methane-slip and high fuel-efficiency.”
MAN Energy Solutions says its ME-GI engine has set a new industrial standard for two-stroke propulsion engines aboard – among others – ro-ro vessels, PCTCs, container vessels, bulk carriers, tankers and LNG carriers. The Diesel principle provides the ME-GI engine with high operational stability and efficiency and also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts. Furthermore, the ME-GI operational principles feature a seamless change-over between gas operation and diesel operation.
