KNUTSEN LNG CARRIER TO USE RENK HYBRID DRIVE

Thursday, August 8, 2019 

Marine transmission company Renk of Germany has recently gained the first order for its MarHy hybrid drive system.

The system enables ships with two-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 zones with low emissions zones (port areas) and for emergencies.

The drive will be fitted to a newbuild 30,000m3 LNG carrier for Knutsen. It is equipped with a 6,000 kW two-stroke main engine. Renk's scope of delivery includes a tunnel gearbox (type SHHII1600), a fully-automatic PSC-85 (Propeller shaft clutch), elastic couplings, and, for the first time, key electric components. These include a 1 MW generator/e-motor as well as the corresponding frequency converter. In addition, Renk is responsible for the system integration.

After completion of the ship at the Hyundai Mipo shipyard in South Korea, it will operate in the Italian Mediterranean Sea for Milan-based Edison Energy. The LNG carrier 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.
