German propulsion professional Schottel has actually introduced a DP-optimized tail prop for the overseas wind market.
The firm stated that the tail prop has actually been created to fulfill the expanding needs for W2W vessels to run effectively and also accurately.
“The SRP-D (“Dynamic”) is a further improved variant for highly demanding DP operations in service operation vessels. When developing the SRP-D, extensive CFD simulations and calculations were taken into account,” Schottel stated.
Manfred Heer, VP Technology at SCHOTTEL: “With the SRP-D, we have significantly increased the DP performance of our rudder propellers, resulting in a product that meets the requirements of today’s offshore wind industry even better. Based on the proven principle of the SCHOTTEL RudderPropeller, a cost-efficient yet powerful solution has been developed that greatly improves the positional accuracy of the vessel for the special DP requirements of these applications. For customers, this means a significant increase in safety and possible operating times on offshore structures, especially in difficult weather conditions.”
According to Schottel, the brand-new SRP-D variations are defined by decreased prop acceleration/deceleration times.
“In combination with a high-speed azimuth steering system with reinforced gear components, the SRP-D enables faster thrust allocation than conventional rudder propellers. Thanks to the shorter response times, it is possible to react faster and in a more targeted manner to external forces from wind, weather and currents, thus achieving a higher positional accuracy of the vessel. At the same time, fuel consumption is reduced,” Schottel stated.
“In addition, the SRP-D is marked by its extremely low profile, vertically integrated LE-Drive as well as an additional eight-degree tilt of the lower gearbox,” the firm included.
Also, per Schottel, in spite of its incorporated layout, the LE-Drive enables a complimentary selection of electric motor for vessels with electrical, preferably battery-supported power supply. Due to its small layout, the LE-Drive opens a lot more liberty in vessel layout. The SRP-D is additionally additionally readily available with drive train in Z-configuration.
Furthermore, many thanks to the extra reduced transmission that has a 8 levels down tilt, the communication in between propulsion device and also hull along with the prop circulation communication, are decreased. This leads to raised drive effectiveness in DP procedure and also lessens “prohibited areas.”
