MAN Diesel and Turbo has supplied a complete propulsion system for an ultra-modern chemicals tanker operated by Germany’s Gesellschaft für Öltransporte (GEFO).

The company says the order, comprising a 7L32/44CR engine, Renk gears and an Alpha adjustable CP propeller, represents a breakthrough for the 32/44CR series in the small twin-hulled tanker sector of the market.

Klaus Deleroi, head, medium speed business unit, MAN Diesel and Turbo, said: “The MAN 32/44CR engine impressed GEFO with its high reliability, compact design, low running and maintenance costs and low exhaust and noise emissions.”

Built at MAN’s plant in Augsburg, the 7L32/44CR engine has an output of 3,920kW and drives a Man Alpha Mark 5 adjustable propeller via a reduction gear unit from Renk. This combination is said to boost the system’s efficiency by up to 9%, helping to save both fuel and costs as well as reduce emissions.

The gears also have a pinion shaft which operates a Cummins generator to supply the ship’s power (PTO mode). The generator can also serve as an electrical motor to drive the propeller at reduced speeds and when the main engine is offline (PTH mode).

MAN’s 32/44CR engine was developed as a drive and auxiliary engine for use on ships, for the offshore industry and for stationary applications. With electrically controlled injection, variable valve control and efficient turbochargers, it combines all of the latest technologies available for large diesel engines.

The tanker, Fidelio, is the first in a series of three new designs featuring the MAN drive train, to also include the Othello and Traviata, which are due to be delivered later this year.

“We focused intently on the dimensioning and design of the tankers to achieve the best possible efficiency. The modern MAN Common Rail engines and propeller optimisation with a MAN Alpha propeller played a key role in this,” added Michael Blume, technical project manager, GEFO.

Fidelio has a DWT of 6,366 and can transport 260 types of petro-chemical materials. Fidelio’s main routes will be in northern Europe, but the tanker is also equipped for worldwide operation and so complies with strict emissions regulations enforced in US coastal waters.
