SRP-D has an its extraordinarily low profile, vertically built-in LE-Drive and an extra eight-degree tilt of the decrease gearbox.
Propulsion system specialist Schottel, Spay, Germany, has launched a brand new rudder propeller optimized for DP (dynamic positioning) use.
Meeting the rising necessities for W2W (walk-to-work) vessels to function effectively and reliably, the brand new SRP-D is an extra improved rudder propeller variant for extremely demanding DP operations by service operation vessels.
“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,” says Manfred Heer, vice president-technology at Schottel. “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.”
In creating the SRP-D, in depth CFD simulations and calculations had been taken under consideration.
The new SRP-D variants are characterised, above all, by decreased propeller acceleration/deceleration occasions. In mixture with a high-speed azimuth steering system with bolstered gear elements, the SRP-D allows sooner thrust allocation than standard rudder propellers. With shorter response occasions, it’s potential to react sooner and in a extra focused method to exterior forces from wind, climate and currents, thus reaching the next positional accuracy of the vessel. At the identical time, gasoline consumption is decreased.
In addition, the SRP-D has a particularly low profile, vertically built-in LE-Drive and an extra 8-degree tilt of the decrease gearbox.
Despite its built-in design, the LE-Drive permits a free alternative of motor for vessels with an electrical, ideally battery-supported, power provide. Due to its compact design, the LE-Drive opens up extra freedom in vessel design.
The SRP-D is optionally additionally out there with the drive prepare in Z-configuration.
Thanks to an extra decrease gearbox downward tilt of eight levels, the interplay between propulsion unit and hull in addition to the propeller circulation interplay are decreased. This leads to elevated thrust effectivity in DP operation and minimizes “forbidden zones.”
Schottel propulsion programs hav been put in in over 600 offshore vessels with latest offshore wind sector references together with the just lately delivered service operation vessels, such because the Louis Dreyfus Amateurs Wind of Hope and the Bibby WaveMaster Horizon, and the set up vessels Voltaire and Les Alizés that are at the moment being constructed for Jan De Nul.
