The PSA Wayra ASD tug will quickly enter service for PSA Marine Peru, an entirely owned subsidiary of PSA Marine (Pte) Ltd, as the primary tug with a hybrid drive system on South America’s west coast.
Hong Kong-based Cheoy Lee Shipyards has constructed the PSA Wayra on the RAmparts 2400W design from Robert Allan Ltd. The tug is propelled by SCHOTTEL RudderPropellers that includes patented SYDRIVE-M know-how. This mechanical hybrid resolution with out the expensive complexity of widespread hybrid know-how reduces each the vessel’s upkeep prices and its gasoline consumption. It has a very environment friendly and sustainable impression on the operation profile of harbor tugs that often alternate between towing and transit operations.
The predominant propulsion of the ASD tug consists of two diesel-driven kind SRP 460 SCHOTTEL RudderPropellers (2,240 kW every) that includes fixed-pitch propellers with a diameter of two.6 metres. With this thruster configuration, the 24.4-metre-long and 11.25-metre-wide tug has greater than 70 tonnes of bollard pull.
Besides this, the rudder propellers function the licensed SCHOTTEL LeaCon sealing system which supplies protected and dependable safety in opposition to contamination of seawater by working supplies.
SYDRIVE-M connects a port and starboard mounted azimuth thruster in a single vessel, permitting the thrusters to be pushed collectively by solely one of many predominant engines. This then reduces predominant engine working hours, thus decreasing upkeep prices in addition to much less gasoline consumption and decrease emissions.
The system wants no extra electronical elements which affords many benefits as demonstrated by three predominant working modes: Light Operation or Free Sailing Mode, Full Thrust Operation Mode and FiFi Mode.
