Wärtsilä has announced that it is supplying propulsion packages for 24 new vessels being built in China for Singapore-based operator China Navigation Co. The engines are being built by licensee Hudong Heavy Machinery.

All of these vessels will be equipped with electronically-controlled two-stroke main engines, FP propellers and seal and bearing systems from Wärtsilä. Four are Chief class multi purpose vessels (MPV), with an option for an additional four, and a further eight are S-Class MPVs, all designed by Neptune Shipdesign, Rostock Germany. Both vessel types are to be equipped with RT-flex58T, version D engines, with 13,560kW-rated six cylinder versions for the S-Class vessels and with five cylinders and 10,000kW for the Chief class. Both ship types are being built at the Zhejiang Ouhua shipyard. The MPVs are designed to carry containers, general cargo, project cargo, steel, timber, agricultural products and dry bulk cargo. Deliveries have already begun, with the first S-Class series, Shansi, in March 2013, to be followed by sister ships Shantung in June and Shaoshing in July.

The other 12 newbuilds are W-Class Handysized bulk carriers, plus eight options, based on the B.Delta37 concept by Finnish designer Deltamarin. The vessels will all be built at the Chengxi shipyard and are all powered by 6,050kW RT-flex50 version B main engines. The first in class Wuchang has been launched and will be delivered in September.

"The propulsion system selected for our new S-class series fully meets our requirements. The first operational results from the Shansi have been very successful. They show that the Wärtsilä RT-flex common-rail engines enable us to operate the vessel very efficiently over a very wide operating range at different speeds. The fuel consumption of the S-class is even better than we expected in the design phase," said Martin Cresswell, fleet director at CNCo.

"These major orders represent clear evidence of the strong global confidence that the shipping industry has in Wärtsilä's propulsion solutions. The specifications called for operational flexibility to operate at different vessel speeds with high efficiency and with the lowest fuel consumption per tonne mile possible, and the choice of Wärtsilä main engines and propulsion machinery reflects these aims," said Rolf Stiefel, sales director two-stroke, Wärtsilä Ship Power.
