MAN wins order for dual-fuel engines

In total, MAN will supply four dual-fuel MAN B&W 6S6OME-GI engines for two hybrid, 8,000 lane-metre Ro-Ro vessels for the Luxembourg-based shipping group CLdN.

The two newbuilds will have a hybrid propulsion system with each featuring 2 × ME-GI engines (2 × 11 MW) along with MAN Energy Solutions’ propietary EGR (Exhaust Gas Recirculation) emissions system.

Once fitted with their 6MW electric propulsion motors, which allow a service speed of 16-17 knots in full electric mode, each vessel will have two 678kWh batteries so that in port these can be used in zero-emission operations.

CLdN says that compared with its largest vessels currently in service, the new ships – the largest investment in its history – will reduce carbon intensity by 40% while being NO_x Tier III-compliant.

”At CLdN, we pride ourselves on minimising our environmental footprint and hybrid propulsion is an exciting step for us,” said COO Shipping, CLdN Gary Walker. ”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.”

“This order features a technologically advanced propulsion-train and having the ME-GI engines at its heart makes it a truly future-proof solution,” said Thomas Hansen, Head of Promotion and Customer Support, with MAN Energy Solutions. ”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 RoRo operators in the world, while pushing its ambition to further reduce its own carbon footprint.”

The diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts. Operational principles features a seamless change-over between gas and diesel operation.

MAN Energy Solutions has also developed an ME-LGI (-Liquid Gas Injection) dual-fuel engine that expands the company’s dual-fuel portfolio, enabling the use of sustainable fuels such as green methanol.

It has also announced the arrival of an ammonia-fuelled variant from 2024.
