Wärtsilä has secured a contract to deliver propulsion packages for 24 new vessels being built at the Chengxi and Zhejiang Ouhua shipyards in China for Singapore-based operator China Navigation (CNCo).
Engines to be fitted on China Navigation’s vessels are being built by Wärtsilä licensee Hudong Heavy Machinery (HHM), based in Shanghai, China.
Under the deal, all the vessels will be equipped with electronically-controlled two-stroke main engines, fixed pitch propellers (FPP) and seal and bearing systems from Wärtsilä.
Additionally, there are options to equip 12 more multipurpose vessels (MPVs) to bring the total number of fitted vessels to 36.
CNCo’s 24 new vessels include four Chief class MPVs, with an option for another four, as well as eight S-Class MPVs, all designed by Neptune Shipdesign, Rostock, Germany.
The S-Class vessels will have a length of 199m, beam of 28.2m, depth of 15.5m and will be capable of carrying 31,000dwt on a 10.5m draft at a design speed of 15.5kts, with a fully loaded vessel reaching a top speed of 18kts.
Chief class vessels will have a length of 175.1m and will be able to carry 22,000dwt on a 9.5m draft at a design speed of 15.5kts with a maximum speed of 17.5kts when fully laden.
Both vessel types will be fitted 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.
Designed for transporting containers, general cargo, project cargo, steel, timber, agricultural products and dry bulk cargo, the Chief class and S-Class MPVs will be operated in CNCo’s Pacific Liner trades.
Deliveries have already begun from the Zhejiang Ouhua yard, with the first S-Class series ‘Shansi’ in March 2013 to be followed by sister ships Shantung and Shaoshing.
The remaining 12 newbuilds are W-Class Handysized bulk carriers, plus eight options, based on Finnish designer Deltamarin’s B.Delta37 concept.
The vessels will also be built at the Chengxi shipyard and will be powered by 6,050kW RT-flex50 version B main engines.
The W-Class Bulk Carriers, which also feature cranes to increase their cargo handling capabilities, will be trading worldwide in CNCo’s Swire Bulk dry bulk division.
The first in class ‘Wuchang’ has been launched and is scheduled to be delivered in September 2013.
Wärtsilä Ship Power director of sales 2-stroke Rolf Stiefel said, "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."
