Two new marine geological research vessels under construction in China will feature a broad scope of Wärtsilä engines and propulsion equipment.
The new vessels are being built at the Shanghai shipyard of China State Shipbuilding Corp. (CSSC) and the COSCO shipyard in Guangdong, on behalf of the Qingdao Institute of Marine Geology and the Guangzhou Marine Geological Survey.
The first vessel for the Qingdao Institute of Marine Geology has a length of 79.8m and deadweight of 4400 ton. For this ship, Wärtsilä will supply four nine-cylinder and one four-cylinder Wärtsilä 20 engines, two transverse thrusters and two sets of Wärtsilä Enviroguard Seals and Bearings. Delivery to the yard is scheduled for July 2016.
The second vessel for Guangzhou Marine Geological Survey has a length of 75.8m and its deadweight is 3300 ton. Three six-cylinder Wärtsilä 26 engines, one four-cylinder Wärtsilä 20 engine, two WST-21 thrusters and two WTT-11 transverse thrusters will power this ship. Equipment delivery will commence in 2016 too.
Research vessels typically have different operating modes, thus requiring the propulsion machinery to have sufficient operational flexibility, Wärtsilä said.
The group has been able to demonstrate that its solutions meet this requirement. Furthermore, in order to make optimal use of the propulsion, Wärtsilä also supports the research Institutes by providing hydrodynamic model testing.
