Chemical tanker has MAN Diesel & Turbo propulsion package

JUNE 23, 2014 — Recently delivered by Turkish shipbuilder Tersan, the 6,336 dwt chemical tanker Fidelio has a MAN Diesel & Turbo propulsion system comprising a 7L32/44CR engine, Renk gears and an Alpha adjustable CP propeller.

The order marks a breakthrough for the 32/44CR series in the small  double-hulled tanker sector of the market.

Built for GEFO (Gesellschaft für Öltransporte mbH) the Fidelio is a duplex stainless steel chemical tanker equipped with electric driven deepwell cargo pumps, nitrogen generator, cargo monitoring systems etc. It can transport 260 types of cargo – from vegetable oil to sulfuric acid. The Fidelio's main routes will be in northern Europe, however the tanker is also equipped for worldwide operation and therefore complies with the strict emissions regulations enforced in U.S. coastal waters. on its maiden voyage from Israel via France to the Netherlands.

The 7L32/44CR engine, built at MAN Diesel & Turbo's plant in Augsburg, has an output of 3,920 kW and drives a MAN Alpha Mark 5 adjustable propeller via a reduction gear unit from Renk. This combination boosts the drive system's efficiency by up to nine percent, 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). With this configuration, the propulsion system guarantees a high level of reliability and excellent cost-effectiveness.

The tanker is the first in a series of three GEFO vessels featuring the MAN drive train that also includes the Othello and the Traviata, set to be delivered in the summer and fall of 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 optimization with a MAN Alpha propeller played a key role in this," says Michael Blume, Technical Project Manager at GEFO. "As a long-established partner, we have already worked closely with MAN Diesel & Turbo during the planning phase".

"The order confirms our customer GEFO's confidence in us," says Klaus Deleroi, Head of the Medium Speed Business Unit at MAN Diesel & Turbo. "The MAN 32/44CR engine impressed GEFO with its high reliability, compact design, low running and maintenance costs and low exhaust and noise emissions."

The 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 highly efficient turbochargers, it combines all of the latest technologies available for large diesel engines. The common rail technology from MAN Diesel & Turbo supports parameters that permit the flexible adjustment of the injection point, duration and pressure. With its highly specific output with simultaneously low fuel consumption and reduced emissions, the 32/44CR is setting new standards in its engine class, says MAN Diesel
