Propulsion over haulings

CPP overhaul and repairs

In Controllable or Variable Pitch Propellers (CPP), the propeller blades are attached to the boss and their pitch can be altered via a hydraulic system. The blades are removable so if they incur damage, can be repaired without removal of the whole propellor.
For the advantages that a CPP system gives, the CPP propellor is also more complex. Instead of the Monoblock design of a Fixed propellor, the CPP has multiple moving parts in the propellor and shaft, and a hydraulic system with which to control the pitching.

ATZ can support you with inspections and repairs afloat, in the dock, or even with a dive team. Either way, ATZ can support all your class-approved CPP propellor requirements.

Fixed Pitch Propulsion over haulings

A fixed pitch propellor (FPP) is typically a single component cast from Bronze. The blades are not removable so if they incur damage, repair is the preferred option. The alternative of propellor replacement is both costly and not short on lead time.
I.R.E can support you with inspections and repairs afloat, in the dock, or even with a dive team. Either way, I.R.E can support all your class-approved FPP propellor requirements.

VSP propulsion over haul

The Voith Schneider Propeller (VSP) combines propulsion and steering in one unit. This unique vessel propulsion solution was developed 90 years ago by Austrian engineer Ernst Schneider. Today, Voith Schneider Propellers are in use all over the world wherever precise, safe, and efficient maneuvering is of the essence.

With the new electric Voith Schneider Propeller (eVSP), we are making an important step towards the electrification of the drive train in marine applications to facilitate more eco-friendly shipping.
