MAN Propulsion System For New Gefo Tanker

Order represents breakthrough for 32/44CR series in small, twin-hulled tanker sector

Posted on June 23, 2014

MAN Diesel & Turbo has supplied a complete propulsion system for a new chemicals tanker operated by Gefo Gesellschaft für Öltransporte mbH.

MAN’s scope of supply comprises a 7L32/44CR engine, Renk gears and an Alpha adjustable controllable pitch (CP) propeller The 7L32/44CR engine, built at MAN Diesel & Turbo’s plant in Augsburg, Germany, has an output of 3920 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 9%, saving both fuel and costs as well as reducing emissions, the company said.

The gears also have a pinion shaft that 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 said this configuration ensures a high level of reliability and cost-effectiveness.

The tanker, christened the Fidelio, can transport 260 types of (petro-) chemical materials, from vegetable oil to sulfuric acid. While the vessel’s main routes will be in northern Europe, the tanker is also equipped for worldwide operation and complies with the strict U.S. coastal emissions regulations. The chemicals tanker was built at the Tersan shipyard in Yalova, Turkey, and is currently on its maiden voyage from Israel to the Netherlands.

MAN said the Fidelio is the first in a series of three new designs featuring the MAN drive train: the Othello and the Traviata are due to be delivered in the summer and fall of this year.
