The engines comprise a diesel electric propulsion system which powers the vessel, MAN Diesel said.
The German marine engineering giant said its four-stroke engines are capable of continuous operation at loads down to 20% and accept overloads of 10% in frequency variation.
Each engine is equipped with jet assist enabling a quick response to high and sharp load variations by directly injecting compressed air into the compressor wheels of the turbochargers.
The engines, which deliver 4,500kW at 720 rpm, also feature low lube-oil consumption of nearly 0.5 – 0.8 g/kWh, the company said.
The 32/40 type engines have been built with selective catalytic reduction (SCR) technology to meet NOx limits.
