Wärtsilä has received the first WTT-40 lateral thruster order and will be delivered in 2016. The first WTT-40 lateral thruster is part of Wärtsilä's new range of lateral thrusters with 4000 kW power and a 3400 mm diameter adjustable pitch propeller. Both power levels and adjustable pitch propellers are within the range of products currently available in Wärtsilä. While Wärtsilä has designed and manufactured a lateral thruster with a power level of 5,500 kW according to a customized version, the WTT-40 transverse thruster and other thrusters of the WTT series are designed to meet the user's high-power lateral thrusters for the bow and stern. Claim.

In response to market demand, Wärtsilä began development of the WTT-40 lateral thruster in 2015. The WTT-40 lateral thrusters are designed to meet the needs of all types of ships, particularly cruise ships, large marine support vessels (OSV) and offshore construction vessels (OCV). The high power levels of the WTT-40 lateral thrusters are particularly important not only for the operation and berthing of large vessels in ports, but also for the dynamic positioning of marine vessels operating under rough sea conditions.

It is reported that because the WTT-40 lateral thruster has a maximum power of 4000 kW, shipyard and cruise ship designers can usually use three WTT-40 lateral thrusters instead of the four smaller lateral thrusters. Lateral thrusters will result in a more efficient design for ships that require less space. The WTT-40 lateral thruster can also be installed closer to the bow to increase efficiency. For the WTT series of WTT-40 lateral thrusters and other sizes of thrusters, adjustable pitch propellers and fixed pitch propellers are available to meet a wide range of ship design requirements.

Extensive experience in Wärtsilä propeller design and computational fluid dynamics analysis for tunnel optimization ensure an optimized solution that delivers propulsion performance, efficiency and minimizes noise and vibration.

Since the Wärtsilä WTT-40 lateral thruster can meet the requirements of the US Environmental Protection Agency VGP2013 rules, all oil-water interfaces must use environmentally acceptable lubricants, such as propeller shaft seals for lateral thrusters, when navigating US coastal waters.

The WTT-40 lateral thrusters are also equipped with integrated hydraulics to save space in the cabin and time to install and commission at the shipyard. Thanks to good lubrication, oil conditioning and ease of maintenance, integrated hydraulics provide reliability and operability for shipowners.
