At Xiamen Shipyard in China, Siem Car Carriers has officially launched its two latest vessels, the ‘Siem Confucius’ and ‘Siem Aristotle’ which are the first, trans-Atlantic PCTCs (Pure Car Truck Carriers) to operate full-time on LNG and are both powered by MAN Energy Solutions ME-GI engines.

The vessels will transport cars for the VW Group between Europe and China.  Each features an MAN B&W S60ME-GI  dual-fuel, two-stroke main engine of 12,600kW with direct injection and exhaust-gas treatment to further reduce emissions. Each main engine is accompanied by two 9L28/32DF and one 7L28/32DF dual-fuel auxiliary engines. The vessels are driven by four-bladed MAN Alpha Kaplan-type fixed pitch propellers of 6.95m which were produced by Chinese licensee Dalian Marine Propeller.

MAN reports that these are the very first L28/32DF units approved for Tier III operation without SCR (Selective Catalytic Reduction), as well as being the first such units to be built by Chinese licensee, CMP. Furthermore, the 28/32DF engines are the first to be built in a 7-cylinder variant. All GenSets are turbocharged by individual MAN TCR 16  (for the 9L28/32DF units) or TCR 18  (for the 7L28/32DF units) turbochargers, with the entire set-up overseen by MAN’s SaCoS engine-control system.

Mikael Adler, VP and Head of Region Asia Pacific – Engines and Marine Systems, said: “I’m very happy to be here for what is the culmination of several years’ work. These vessels represent a new departure and a new ambition with their LNG-fuelled propulsion solution heralding a new era of diminishing emissions within trans-Atlantic shipping as well as within the global, car-manufacturing supply chain. This ties in perfectly with MAN Energy Solutions’ belief that it is time for a ‘Maritime Energy Transition’ to find clean, decarbonised solutions for seaborne trade and transportation.”

Bjarne Foldager, SVP Head of Two-Stroke Business, MAN Energy Solutions, said: “Our dual-fuel portfolio can rightly be considered as mature technology with references now in every major marine segment. With 2020 and the new IMO emissions legislation fast approaching, our dual-fuel engines continue to act as standard bearers for environmentally friendly, reliable propulsion technology with their seamless switching between fuels and elimination of methane slip. Furthermore, the ME-GI’s use of the Diesel combustion principle ensures that it can easily adapt to run on whatever fuels the industry may prefer in the future. With well over 400 sales already amassed by MAN Energy Solutions’ entire portfolio of dual-fuel engines – all running on clean fuels such as methanol, LPG or LNG – these car carriers mark yet another milestone in the development of the dual-fuel market segment and cement the success of the strategy MAN Energy Solutions has laid over the past decade. The machinery we have provided for these vessels also fits with our desire to increasingly become a supplier of complete propulsion solutions.”

VW stores its vehicles at Emmen, Germany, for transport to China. As the shipping of cars from one continent to the other contributes its fair share of emissions, VW – as one of the first OEMs – decided to significantly improve the environmental balance of its marine transport fleet by ordering the new car carriers.

Each of the newbuildings operated by Siem Car Carriers will be capable of carrying 4,700 vehicles. Both will be equipped with two 1,800m3 LNG tanks installed below deck. The vessels are replacing two of nine conventional PCTCs in Siem’s fleet. Each newbuilding is estimated to cut CO2 emissions by up to 25%, NOx by up to 30%, particulate matter by up to 60%, and SOx almost completely. With this new approach, VW is taking a step in cutting down emissions in its supply chain. The VW Group joined the Clean Shipping Network (CSN) at the beginning of 2014 and was the first German car maker to use its index for assessing the environmental impact of its marine transport.
