Product catalog summary
Introduction
Damen Shipyards Gorinchem, a member of the Damen Shipyards Group, specializes in the production of customized propeller nozzles designed to enhance thrust performance. This document outlines various nozzle types, their specifications, and benefits.

Specifications and Types of Nozzles
  • Marin/Wageningen 19A Profile: Known for its use in thrusters, it is available in various L/D lengths and is less focused on reverse thrust.
  • VG 40 Nozzle: Offers the same forward thrust as the 19A but performs better at high speeds due to its shorter profile.
  • Wing Nozzle: Developed in-house, it features a small system diameter and hydrodynamic wing profile, enhancing maneuverability and efficiency at high speeds. Suitable for shellfish cutters, yachts, and research vessels.
  • Optispec Nozzle: Designed for vessels unsuitable for conventional rudder systems, it is a steerable nozzle with a fixed rudder blade, ideal for self-propelled cutter suction dredgers and pushers.
  • Optima Nozzle: Combines the forward thrust of the 19A with the reverse capabilities of the 37, offering versatility across various vessel types. Available in different sizes for specific applications.

Innovative Production Method
The single weld spinning method enhances environmental sustainability by reducing welding and grinding activities. This method allows for efficient production of nozzles with diameters ranging from 1,000 mm to 8 m, using materials like stainless steel and duplex.

Benefits
  • Optimal forward and reverse thrust performance.
  • Reduction in sound levels and vibrations for improved onboard comfort.
  • Increased load allowance due to improved stopping distance, allowing for more cargo capacity.

Customization and Analysis
Damen Marine Components offers analysis of operational requirements to determine the suitability of nozzle installation and provides tailored design recommendations to maximize benefits.

Propeller Nozzles-1

CUS TOMISED NOZ ZLE S Damen Marine Components produces all nozzle types as requested by its customers. The internationally renowned Marin/Wageningen 19A profile can be delivered in various L/D lengths. This nozzle type is often used for thrusters and where reverse thrust is less important. WING NOZ ZLE The Wing nozzle was developed in-house by Damen. Its profile is very short, with a small system diameter and a special hydrodynamic wing profile. The wing nozzle creates optimal manoevrability and increased performance and efficiency at high speed. As a result of the smaller system diameter, vessels using the Wing nozzle can apply a larger propeller diameter. The Wing nozzle is suited for use on vessels such as shellfish cutters, yachts and research vessels. VG4 0 NOZ ZLE The VG 40 has a shorter profile length than the 19A, but delivers the same forward thrust performance. At high cruising speeds the VG 40 outperforms the 19A.

The roots of the Optima nozzle began many years ago at the Netherlands Maritime Research Institute (MARIN). At that time, nozzle type 19A had become the industry standard, offering excellent performance in forward propulsion. Another nozzle, the 37, had been developed to address the requirements of reverse thrust. The challenge that faced the industry was the development of a nozzle that could offer optimal results in both directions. Damen Marine Components stepped up to the mark and delivered the solution: the Optima nozzle. V E R S AT I L I T Y Thanks to its robust profile and excellent performance...
