China Shipping Container Lines Co., Ltd. (CSCL), part of the China Shipping Group (CSG), has chosen Wärtsilä main engines for eight container vessels. The Wärtsilä engines for this order will be built under licence by Doosan Engine, Korea. Wärtsilä, the marine industry's leading ship power system integrator, will supply a package of support services for this order, which was placed in October. The ships are to be built at the Jiangnan Changxing shipyard in Shanghai.
"The low fuel consumption across many load parameters was the key technical reason to select the Wärtsilä common rail 2-stroke engine," said Li Xueqiang, deputy GM of CSCL.
The CSG fleet is largely powered by Wärtsilä engines, and currently has more than 310 Wärtsilä engines in service, including close to 100 low speed main engines and more than 210 four-stroke engines. About 75 Wärtsilä engines are contracted to be delivered during 2010-2012, including more than 20 low speed main engines and 55 four-stroke engines.
This latest order, however, marks the first order for Wärtsilä main engines for CSG's container vessel fleet, which is ranked amongst the world's leaders in terms of operating capacity.
This order calls for Wärtsilä to supply its seven-cylinder RT-flex68TD common rail two-stroke engines for the eight 4700 teu container vessels. The selection of this particular engine type came after CSG scaled down the original speed specified in the design, in line with the downturn in the shipping market, to a maximum of 18 knots.
Wärtsilä's support services for this order will include RT-flex engine training at the Wärtsilä Services facilities in Shanghai using an RT-flex electronic simulator. Additionally, a single RT-flex rail unit will be specially manufactured to enhance the hands-on basic operational training courses. These courses will primarily target the Chinese crew who will operate common rail 2-stroke engines in the future.
CSG continues to develop its partnership with Wärtsilä, adopting many different products and services into its various business areas. For example, CSG's Tanker division, the largest sea-borne tanker fleet in China, has recently taken possession of six product tankers fitted with Wärtsilä RT-flex50 and RT-flex58TB main engines, Wärtsilä Auxpac 20 auxiliary engines, as well as Wärtsilä fixed pitch propellers and thrusters. In total, 80 Wärtsilä Auxpac 20 auxiliary engines have been ordered, including 33 engines already in service.
Currently, four VLCC projects and eight VLOC projects with Wärtsilä RTA84TB main engines and Wärtsilä Auxpac 20 auxiliary engines are under construction. Similarly, four Ropax projects with Wärtsilä 32 four-stroke engines and Wärtsilä 20 Auxpac auxiliary engines are also ongoing. During the past three years, Wärtsilä Services in China has supported CSCL's operation of almost 130 sets of Wärtsilä 32 auxiliary engines via a service agreement. Under this agreement, equipment and parts are continually rolled-over on an exchange basis from one vessel to another. This greatly reduces the overhaul time onboard since preparations can be made in the workshops to be ready for the next CSG ship. It has been a particularly successful model.
