The waste heat recovery system will each be powered by a power turbine generator (PTG) and installed in 8,800 teu container vessels, ABB announced.
“The high efficiency of ABB's turbochargers gives customers not only the option of a waste heat recovery system in the first place, but also the possibility of using this system at lower loads,” said Oliver Riemenschneider who heads up ABB's turbocharging business.
The employment of a waste heat recovery system to increase energy output onboard ships is becoming an increasingly viable means of reducing fuel costs, according to ABB.
In marine propulsion plants, around 50% or more of the energy from fuel is lost to heat when converted to mechanical work by the main engine. By supplementing a ship's main propulsion plant with a waste heat recovery solution, up to 4% of the lost fuel energy can be recovered and converted into electricity. More efficient energy use also reduces carbon dioxide emissions in relation to the engine’s mechanical power output, ABB said.
Among the 14 containerships to use ABB's technology, the first seven post-panamax vessels will be built at Dalian Shipbuilding Industry Co (DSIC) and the other seven vessels at New Times Shipbuilding Co for China International Marine Containers Group Co and Mediterranean Shipping Co (MSC).
When delivered between 2015 and 2016 the ships will serve under a long term charter agreement to MSC.
