A contract has been awarded to MAN Energy Solutions for the supply of four dual-fuel MAN B&W 6S60ME-GI (gas injection) engines for two new-build hybrid ro-ro vessels currently under construction for CLdN.
Each ro-ro vessel will have a hybrid-propulsion system which features two ME-GI engines (2 × 11MW) along with a MAN Energy Solutions’ EGR (exhaust gas recirculation) emissions system. Two 6MW electric propulsion motors will also be fitted to each ship, enabling a service speed of 16-17kts when operating in a fully electric mode. Each of the ship’s electric propulsion systems will be accompanied by two 678kWh batteries.
Furthermore, each ro-ro will be provided with a shore connection to enable zero emissions when in port and each MAN engine will be equipped with a power take off, with each of the vessels’ respective shafts equipped with a clutch ready to deliver a PTH of 6MW.
The diesel principle of the ME-GI engine provides high operational stability and efficiency, but also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts, states MAN Energy Solutions. The ME-GI engine is said to be capable of a seamless changeover between gas operation and diesel operation.
Compared to the largest vessels currently in service with CLdN, the new-build vessels will further reduce carbon intensity by 40% while being NOx Tier III-compliant.
“In 2021, we were announced as top performer among our ro-ro shipping peers in Northwest Europe for CO2 emissions per ton of freight carried,” said Gary Walker, COO shipping, CLdN. “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 minimizing 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-fueled, low-speed prime movers due to their low methane-slip and high fuel efficiency.”
“This order features a technologically advanced propulsion train and having the ME-GI engines at its heart makes it a truly futureproof solution,” explained Thomas Hansen, head of promotion and customer support, MAN Energy Solutions. “ME-GI engines offer the industry’s lowest CO2 and methane-slip emissions for LNG-fueled 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.”
The 234m-long vessels will have a lane capacity of 8,000m and are both scheduled for delivery in the first half of 2025.
