Wärtsilä’s joint venture company CSSC Wärtsilä Engine has been contracted to supply engines for six 21,000 twenty-foot equivalent units (TEU) container vessels being built in China.
Under the contract, the company will deliver a total of 24 units of nine-cylinder Wärtsilä 32 Auxpac generating sets.
The Wärtsilä Auxpac 32 is the auxiliary engine version of the Wärtsilä 32 family, of which more than 1,200 engines are currently in service across the world, Wärtsilä said in a statement.
Said to be the most powerful Auxpac generating set of Wärtsilä, the Auxpac 32 is suitable for large container vessels that require auxiliary power ranging between 2,500kWe and 4,500kWe per generating set.
The embedded engine automation system includes serial bus communication interface to the alarm and monitoring system.
The Wärtsilä Auxpac 32 can run on different fuels, ranging from the lowest light fuel oil (LFO) viscosity of 2.0 centistokes (cSt) to a heavy fuel oli (HFO) viscosity of 700cSt (at 50 °C). The engine can also operate on low and ultra-low sulphur fuel oils.
Deliveries under the contract will begin next year.
Earlier in March, the engine was ordered for eight new CSCL container ships.
The same engines were also ordered for five new container vessels built for China Ocean Shipping Group (COSCO) and for another 11 new COSCO vessels last year.
Wärtsilä Marine Solutions engines vice-president Stefan Wiik said: "It is very clear that the Wärtsilä 32 Auxpac is the right choice for this segment of the market.
"Repeat orders are the most solid endorsement of this fact, and the engine is perfect for ships with an auxiliary power need in the 2,500kWe to 4,500kWe range."
