(HELSINKI, Finland) — Wartsila introduces the latest addition to its thruster product portfolio, the Wartsila WST-14 steerable thruster, which represents state-of-the-art azimuthing propeller technology. It is aimed primarily at inland waterway cargo vessel applications. The new thruster will provide increased reliability and efficiency, while also lowering costs.
Among the many innovations incorporated into the WST-14 are its space-saving compact design, an integrated slipping clutch that provides a cost-competitive solution for maneuvering when combined with a fixed-pitch (FP) propeller, and the ability to maintain and service the propeller shaft and steering seals without requiring a complete overhaul of the thruster. It has a straightforward, reliable design and is ice-class rated.
By combining the six-cylinder in-line Wärtsilä 20 engine with the WST-14 thruster, a solution package that is ideal for the specific demands of river and inland waterway operation can be offered. It also suits other marine applications, such as tugs, where maneuvering in harbors and/or ice conditions is required. Compared to conventional fixed-pitch (FP) and controllable-pitch (CP) propeller drive line solutions, the WST-14 thruster enables a greater load capacity for the vessel. This offers increased revenues for the owner/operator since more cargo can be transported.
“This project began two years ago and we are delighted to announce that the WST-14 is now available to the market. This introduction fills a particular need in the inland waterway vessel sector, and it is already attracting interest from owners and yards in Asia, Europe and America. Wartsila is now able to offer a complete and highly efficient propulsion package for this specific market,” said Arto Lehtinen, vice president, propulsion, Wartsila Marine Solutions.
The WST-14 will be featured at the Neva exhibition to be held in St. Petersburg, Russia from Sept. 22-25.
