MAN Energy Solutions has won an order for four dual-fuel MAN B&W 6S60ME-GI engines in connection with the construction of two hybrid, 8,000 lane-metre, ro-ro vessels for Luxembourg-based shipping group CLdN.
Both 234m vessels are scheduled for delivery in the first half of 2025. The two newbuildings will have a hybrid propulsion system with each featuring two ME-GI engines (2 × 11MW) along with MAN Energy Solutions’ propietary EGR (Exhaust Gas Recirculation) NOx reduction system.
Both vessels will be supplied with two 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 two 678kWh 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.
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.
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.”
Thomas S Hansen, Head of Promotion and Customer Support, MAN Energy Solutions, said: “This order features a technologically advanced propulsion train and having the ME-GI engines at its heart makes it a truly future-proof solution. ME-GI engines offer the industry’s lowest CO2 and methane slip emissions for LNG-fuelled vessels. The engines’ green credentials also boost CLdN’s current status as among the greenest ro-ro operators in the world, while pushing its ambition to further reduce its own carbon footprint.”
