At the end of March, 2019, the maritime sales team of RENK’s Rheine plant won the first new construction project for the maritime hybrid system MARHY.

This system enables ships fitted with 2-stroke engines to efficiently generate on board power supply by using the main engine (PTO-operation). In addition, a fully electric drive (PTH-operation) is available for areas with low emissions zones (port areas) and for emergencies.

The newbuild is a 30,000 cu m LNGC owned by Knutsen OAS. She is fitted with a 6,000 kW 2-stroke main engine.

RENK delivered a tunnel gearbox (type SHHII-1600), a fully-automatic PSC-85(propeller shaft clutch), elastic couplings, and, for the first time, key electric components, including a 1 MW generator/e-motor, as well as the corresponding frequency converter.

In addition, RENK was responsible for the system integration. After completion of the ship at the Hyundai Mipo shipyard, she will be stationed in the Italian Mediterranean Sea and will be operated by Milan-based Edison Energy.

This LNGC is part of an infrastructure strategy, which provides for the construction of several LNG depots along the Italian coast to provide a reliable energy supply.
