Four years after its market release in May 2008, the VTA reference list exceeds 100 entries, covering the TCR20, TCA55, TCA66, TCA77 and TCA88 turbocharger frame-sizes. As such, VTAs are installed on four-stroke gas engines and medium- and large-bore two-stroke diesel engines powering bulkers, tankers and container vessels to support ship operators’ part-load or slow-steaming strategy.
In recognition of this achievement, MAN Diesel & Turbo was awarded the prestigious Sea Trade Award for the VTA in the Protection of the Marine and Atmospheric Environment category in 2010.
The first unit delivered for commercial use has, to date, accumulated more than 20,000 operating hours running on HFO and confirmed its reliable operation as well as fuel savings of up to 5 g/kWh. In addition to the fuel savings, the VTA will also contribute to the reduction of the Energy Efficiency Design Index (EEDI) when it comes into force for ships built after 2013.
