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:
Crack detection by dye penetration/NDT-method on main machine_1
Machining of liner guiding on main engine_3
Gear wheel damage on chain drive_2
Consequential damage after connecting rod bearing damage on auxiliary diesel_1
Pattern of damage on cam for valve timing as a result after connecting rod bearing damage on auxiliary diesel_3
Mechanical machining (machining of liner guiding) on auxiliary diesel_5
Damage pattern upper liner guiding_2 (crack detail)
Gear wheel damage on chain drive_1
Gear wheel damage on chain drive_3
Pattern of damage on cam for valve timing as a result after connecting rod bearing damage on auxiliary diesel_2
Pattern of damage on liner landing surface on auxiliary diesel_4
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:
Prior to many machining repairs on stern tubes, a laser measurement takes place (here of the bearing alley)
Mechanical machining of a shaft on a bulkhead penetration
Preparation for machining of a fastening bolt on a flunk of a pitch propeller_1
Propeller shaft outside_3 (damage run-in marks2)
Propeller shaft outside_5 (re-machining shaft2)
Propeller shaft outside_7 (polishing of shaft)
Propeller shaft outside_9 (machining completed)
Landing surface for pitch propeller_2 (drill out of bolt for cutting of a new thread)
Landing surface for variable pitch propeller_4 (thread cutting)
Landing surface for pitch propeller_6 (insert center sleeve1)
Landing surface for pitch propeller_8 (machining completed)
Sterntube bearing 1_2 – machining of bearing alley2
Sterntube bearing 2_1 – machining of bearing alley1
Condition of a stern tube with flange surface
New sealing surface after mechanical machining of a shaft on a bulkhead penetration
Propeller shaft outside_2 (damage run-in marks1)
Propeller shaft outside_4 (re-machining shaft1)
Propeller shaft outside_6 (machining of introduction area)
Propeller shaft outside_8 (check roughness)
Landing surface for pitch propeller_1 (damage of thread)
Landing surface for pitch propeller_3 (drilling of hole before inserting new screw socket)
Landing surface for pitch propeller_5 (thread cutting2)
Landing surface for pitch propeller_7 (insert center sleeve2)
Sterntube bearing 1_1 – machining of bearing alley1
Sterntube bearing 1_3 – machining of bearing alley3 (completed)
Sterntube bearing 2_2 – Machining of bearing alley2 (completed, new bearing installed)
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 of a hydraulic ram
Hinge bores
Dimensions of the mounting_1
Dimensions of the mounting_2
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:
Device setup
Machining of bearing/guiding surface
Assembly
Drill fitting bolt_1
Drill & spindle fitting bolt_3
Machining of gearbox bearing
Inductive heating of bearing shell
Bearing shell renewed
Drill & spindle fitting bolt_2 (machining with magnetic drilling machine)
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 machining of the rudder trunk (bore out)_1
Overhaul of a rudder stock due to heavy wear marks (removal with our co-operation partners)
Damage pattern on rudder stock_2
Mechanical machining completed on several areas of the rudder stock
Rudder machine foundation bolt renewal_2
Rudder engine foundation bolt renewal_4 (reamer)
Mechanical machining of the rudder trunk (bore out)_2
Damage pattern on rudder stock_1
Mechanical machining of the surfaces on the rudder stock_1
Mechanical machining of the surfaces on the rudder stock_2
Rudder machine foundation bolt renewal_1
Rudder machine foundation bolt renewal_3 (fitting bores)
Rudder engine foundation bolt_5 (final measurement)
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:
Bearing repair bollard pull winch_1
Bearing repair bollard pull winch_3
Bearing repair bollard pull winch_2 (width of the bearing bush)
Bearing repair bollard pull winch_4 (new bearing bush)
