Hapag-Lloyd has received energy efficiency design index (EEDI) certification from Germanischer Lloyd for its 8,750 TEU container ship Vienna Express.
The certificate was issued in accordance with voluntary EEDI guidelines set out in a circular from the IMO’s Marine Environmental Protection Committee.
The EEDI, which will likely become a future mandatory newbuilding standard, compares theoretical CO2 emissions and transport work of a vessel (gCO2 / (t*nm)), which will then be benchmarked against an IMO-set requirement.
The vessel, delivered by Hyundai Heavy Industries, has improved fuel consumption technology and its main engine performance, originally designed for 68,640kW, was reduced to 51,480kW.
The ship also has a variable exhaust gas bypass for the turbocharger, which is regulated by the electronic engine control, according to marinelog.com.
The overall lower fuel consumption increases the vessel’s endurance to 27,700 nautical miles from 23,300.
