Plan & prepare
Confirm isolations, access, lifting points, scaffolding and the controlled removal sequence.
Naude Industries / Mechanical / Tailshaft & Rudder Services
Marine propulsion supportTailshaft & rudder services.
Practical support for propeller, tailshaft, stern-tube and rudder work-from dry-dock preparation and controlled dismounting to survey support, repair coordination and reinstatement.

Mechanical work beneath the vessel
Controlled removal. Measured inspection.
Tailshaft and rudder work depends on safe access, controlled handling and a planned sequence that protects both the vessel and the components being removed.
Naude Industries can coordinate the practical mechanical, rigging, access, welding and workshop activities included in the agreed scope. Survey, NDT, dimensional checks and specialist services are defined with the client or attending authority before work begins.
Propeller removal & refitting
Coupling disconnection
Tailshaft withdrawal
Shaft calibration support
Stern-tube bearing checks
Seal arrangement cleaning
Rudder dismounting
Pintle access & inspection
Typical work sequence
From dry-dock access to reinstatement.
The final method and inspection points are matched to the vessel, shaft arrangement, rudder design and survey requirements.
Disconnect
Remove coupling bolts, dismount the coupling and prepare the propeller and shaft arrangement.
Withdraw & handle
Withdraw the tailshaft using controlled lifting and handling, then transfer components for inspection.
Inspect & measure
Support shaft calibration, taper and key inspection, NDT and stern-tube bearing measurements as specified.
Repair & prepare
Complete or coordinate agreed machining, cleaning, component repairs and sealing-arrangement work.
Rudder work
Open inspection access, address locking arrangements and pintle work, and dismount the rudder when required.
Reinstall
Return components to the vessel, refit the shaft, coupling, propeller and rudder items included in scope.
Check & hand over
Complete agreed clearances, alignment checks, records and practical handover evidence.
Featured project
Vessel tailshaft removal & overhaul.
A real dry-dock work sequence showing purpose-arranged access, coordinated trades and controlled shaft withdrawal beneath the vessel.
Scale, access and mechanical control.
The removal stage shows access arranged beneath the hull, the working team positioned around the shaft line, and the tailshaft supported during controlled withdrawal before workshop inspection and fitting activities.
Propeller and shaft workshop work
Taper contact checked and matched.
Fresh project evidence showing the propellers and corresponding shaft tapers inspected and trial-fitted in the workshop.
Inspection beyond the dry dock.
Following removal, the propellers and corresponding shaft components were transferred to the workshop. The tapers and propeller hub bores were cleaned and prepared, with engineer’s blue used to assess the mating contact pattern during progressive trial fitting.

Tailshaft & rudder capability
One coordinated marine work front.
These projects commonly require several connected disciplines. Naude Industries can coordinate the relevant work within one defined scope and interface with the client, dry dock, surveyor and specialist service providers where required.

Classification attendance, specialist NDT, machining, balancing, replacement bearings, seals and third-party certification are confirmed separately where required.
Common questions
Planning tailshaft and rudder work.
Can Naude Industries remove and reinstall a vessel tailshaft?
Yes, subject to the vessel arrangement, dry-dock access, lifting requirements and agreed scope. Work can include coupling and propeller activities, shaft withdrawal, transfer for inspection and controlled reinstatement.
Do you complete tailshaft measurements and NDT?
Dimensional checks, shaft calibration and access for NDT can be included or coordinated. The required inspection method, acceptance criteria and attending authority must be confirmed for the project.
Can rudder removal be included?
Yes. The scope may include inspection access, pintle locking arrangements, rigging, rudder dismounting, lowering and reinstatement according to the vessel design and agreed method.
What information is needed for a quotation?
Provide the vessel name and location, docking dates, shaft and propeller arrangement, rudder details, available drawings, survey requirements, photographs and the exact removal, inspection and reinstatement responsibilities.
