Optima Nozzle
CFD-redesigned Optima propeller nozzle with up to 3.4% more thrust and strong reverse thrust, in L/D 0.4 and 0.5 versions, for tugs, pushers, dredgers, icebreakers and workboats.
Description
The Optima Nozzle from Damen Marine Components has been used on pushers, tugs, icebreakers, dredgers, coasters, fishing vessels and workboats since 1998. In 2023 it was redesigned using CFD, generating up to 3.4% more forward and reverse thrust than its predecessor.
Key features
- Strong forward and reverse thrust; lower fuel consumption
- Reduced sound levels and vibrations
- Replacement fits existing constructions without vessel modification
- Single-weld spinning production: inside diameters from 1,000 mm to 5.3 m outside, in stainless steel, duplex, steel and special steels
Configurations
- L/D 0.4: less engine output for ice-class vessels, lower resistance at high speed; for coasters, fishing vessels and others up to 14 knots
- L/D 0.5: for hoppers, pushers, tugboats, AHTS and inland waterway vessels
