System Overview & Architecture
Integri Marine delivers complete lifecycle engineering for this system — from conceptual feasibility studies and bespoke hardware integration to afloat or drydock installation and sea-trial commissioning.
Integri Marine & Offshore Services is the Authorized Representative for Schneekluth Hydrodynamik Germany, bringing the industry's most successful hydrodynamic energy-saving device — the Schneekluth Wake Equalizing Duct (W.E.D.) — to shipowners and vessel operators.
As the world's most widely deployed hydrodynamic power-saving device, the Schneekluth WED is a proven hydrodynamic nozzle mounted on the stern hull directly in front of the propeller. It optimizes inflow velocity distribution, reduces flow separation at the afterbody, and generates a forward thrust component.
The system delivers substantial fuel savings (or equivalent speed gain) and significant reduction in propeller-induced vibrations. Featuring zero moving parts and zero maintenance costs, the Schneekluth WED offers rapid payback for any hydrodynamic retrofit solution.

The Schneekluth Wake Equalizing Duct (WED) is a hydrodynamic nozzle system mounted on a vessel's stern hull directly in front of the propeller. It optimizes inflow velocity distribution to the propeller, reduces flow separation at the afterbody, and generates a forward thrust component. Developed by Prof. Schneekluth and the Duisburg Research Laboratory in Germany, it is the world's most widely deployed hydrodynamic power-saving duct.
Vessels equipped with the Schneekluth WED achieve proven fuel savings at equivalent vessel speeds, or a proportional increase in speed at the same engine power output. Numerous merchant vessels globally have been equipped with the WED, demonstrating consistent fuel economy and emissions reduction.
The Schneekluth WED reduces propeller-excited hull vibrations by up to 50%. By straightening the inflow velocity distribution and reducing peak tip loading in the upper propeller quadrants, the duct minimizes hydrodynamic pressure pulses transmitted to the hull. This decreases structural fatigue, protects sensitive onboard electronics, and significantly improves crew working and living comfort.
Integri Marine & Offshore Services is the official Authorized Representative for Schneekluth Hydrodynamik Germany. We provide end-to-end support for shipowners: initial hydrodynamic assessment, detailed hull mapping, coordination with Schneekluth Germany for custom duct sizing and design, procurement, engineering integration, and drydock installation supervision.
No. Fitting a Schneekluth WED subsequently to an existing ship requires no constructional changes to the vessel's hull lines and no modifications to the existing propeller design. The duct is custom-shaped to fit the vessel's existing stern geometry during standard drydocking.
