Engines
There are hardly any landing and contact surfaces, and end faces that we cannot machine on engines! These can be, e.g., liner guidings, crank- and/or main bearing journals as well as bearing alley on main or auxiliary engines, bearing shields and bearing bushings on attached generators or other components. Basically, we can be on site quickly with the right tools and machining equipment to fix your problem.
Below you will find a few typical repair examples:

Gear damage_1
Gear damage_2
Gear damage_3
Machining after piston breakage on auxiliary diesel_1
Machining after piston breakage on auxiliary diesel_2
Machining after piston breakage on auxiliary diesel_3
Machining after piston breakage on auxiliary diesel_4
Machining after piston breakage on auxiliary diesel_5
Propulsion
The machining of bearing-, contact surfaces and end faces of the entire drive train, from the engine (whether with or without gearbox) to the stern tube (including its sealing) and the drive shaft is just as much a part of our daily work as the processing of contact surfaces and end faces on variable pitch propellers and the spindling of holes for retaining bolts, including thread renewal.
Examples of repairs are as follows:
Stern tube laser measurement of bearing line
Processing sterntube seal_1
Processing sterntube seal_2 (machining the surface)
Processing stern tube seal_2 (new bearing inserted)
Propeller shaft outer_1 (propeller fastening to shaft)
Propeller shaft outer_2 (run-in track depths)
Propeller shaft outer_2 (run-in track depths2)
Propeller shaft outer_4 (remachining propeller shaft)
Propeller shaft outer_5 (remachining propeller shaft2)
Propeller shaft outer_6 (machining the introduction phase)
Propeller shaft outer_7 (polishing)
Propeller shaft outer_8 (check roughness depth)
Propeller shaft outer_9 (machining completed)
Contact surface for controllable pitch propeller_1 (thread damage)
Contact surface for controllable pitch propeller_2 (drill out bolt)
Contact surface for controllable pitch propeller_3 (spindling out hole)
Contact surface for controllable pitch propeller_4 (cutting thread)
Contact surface for controllable pitch propeller_5 (cutting thread2)
Contact surface for controllable pitch propeller_6 (insert centering bushing)
Contact surface for controllable pitch propeller_7 (insert centering bushing2)
Contact surface for controllable pitch propeller_8 (work completed)
Stern tube bearing_1 (spindling the bearing track)
Stern tube bearing_2 (spindling the bearing track2)
Stern tube bearing_3 (spindling the bearing track3)
Stern tube bearing2_1 (spindling the bearing track)
Stern tube bearing2_2 (new bearing mounted)
Cranes
During operation, shipboard cranes are subject to high loads on the bearings of the rope sheaves and the slewing ring. Whether the bushings of the rope sheave shafts or the bearing surface of the slewing ring: We can work on all end faces, sealing-, contact- and bearing surfaces on your cranes as well as on your grabs of the loading/unloading gear.
Below please find examples of repair areas:
Trunnion mount
Distance between the flanges
Length of the flanges
Joint hinge holes
Gearboxes
The teeth need to mesh perfectly again? We make sure of that for you. Whether on bearing guidings of the gears, bearing bushings, complete bearings in the gearbox or the corresponding shafts, on the housing or the foundation mountings outside: we machine and polish on your premises, in the case of major damage we support individual components and get the system running again.
Here you can find exemplary repairs:
Gearbox standard repair_1 (spindling out bearing surface)
Gearbox standard repair_2 (spindling out bearing surface2)
Gearbox standard repair_3 (spindling out bearing surface3)
Gearbox standard repair_4 (inductive heating of bearing shell)
Gearbox standard repair_5 (bearing shell replaced)
Gearbox standard repair_6 (assembly)
Drilling & spindling dowel pins_1
Drilling & spindling dowel pins_2 (machining with magnetic drilling machine)
Drilling & spindling dowel pins_3
Steering
Whether on rudder trunk, rudder engines, rudder shafts or other components of your steering system – we will get your ship back on course with mechanical machining on site. If you experience such a severe damage that there is not enough material left to turn to the new correct installation dimension, we’ll solve this problem with build-up welding or a bushing.
The following are examples of typical repair applications:
Mechanical processing of rudder cokers_1
Mechanical processing of rudder cokers_2
Replacing the rudder shaft foundation bolts_1
Replacing the rudder shaft foundation bolts_2
Replacing the rudder shaft foundation bolts_3
Replacing the rudder shaft foundation bolts_4 (fitting holes)
Replacing the rudder shaft foundation bolts_5 (reamer)
Replacing the rudder shaft foundation bolts_6
Machining rudder stock_1 (removal)
Machining the rudder stock_2 (damage pattern)
Machining the rudder stock_3 (damage pattern2)
Machining the rudder stock_4 (damage pattern3)
Machining the rudder stock_5 (refurbishing the surfaces1)
Machining the rudder stock_6 (refurbishing the surfaces2)
Machining the rudder stock_7 (refurbishing completed)
Winches
Whether bollard pull winches, combined windlass/mooring winches, mooring winches and coupling winches – we can also machine, measure and align the bearings, shafts, bushings and foundations. If required, we can also manufacture the bushings and supply the bearings.
In the example of this bollard pull winch, the bearings were bored out on both sides and new bearing bushing were inserted:
Bollard pull winch_1
Bollard pull winch_2
Bollard pull winch_3
Bollard pull winch_4
