Since every damage case is unique, our engineers and machining experts assess the damaged components and are able to offer the best combination of repair method:
• Crankshaft post heat treatment in order to lower the hardness of the overheated areas
• Material removal by cutting, which is the safest method to prevent further heating damages of the crankshaft material
• Grinding of radius areas and oil inlet holes
• Superfinish (polishing) of the final surface

Fretting between main bearing shells and girders on large 2-Stroke engines can roughen up the girder surface and complicate the bearing exchange.
We are available to customize the machining basket to any journal size so as to machine or polish the affected girder areas located under the fitted crankshaft.

YOUR BENEFITS
You can save long auxiliary engine downtimes or minimize off-hire times of your main engines. By machining the crankshaft in place without dismantling it from the engine, the repair time and costs are drastically reduced.
With our many years of experience in crankshaft repairs we can guarantee a desirable result.

OUR SERVICES
All types of crankshafts:
• Main Bearing Journal repairs
• Crank Pin repairs
• Pin and journal diameter between 170-1200mm
• Possibility to machine the 2-Stroke main bearing girders (saddles) without lifting the crankshaft
• Material can be removed by cutting (bits) rotating grinders or superfinish oscillating head
• The machining depth can be reduced by heat treatment (annealing) of the overheated surface

 
With our wide range of line ore machines and experience from various repairs, our innovative machining experts are able to propose a suitable repair method.
In-line bores and cylindrical survaces can be machined by a cutting bit rotating on a well supported shaft.
• Machining of in-line bores of 80mm to 600mm diameter
• Maximizing the length of machining channel is 6000mm
• Machining of flanges and sealing surfaces up to diameters of 700mm (expandable) 120mm axial machining length possible

Our laser alignment equipment can be used to align the boring bar in long bearing channels and can also be used to verify the final result.

We have highly qualified and skillful Retrofit Pulse Lubrication System(RPLS) installation teams with retrofit experience on numerous vessels.
With only one contact, you can cover your entire retrofit workscope including dismantling of existing systems, piping remake, fitting of new components, electrical work, and recommissioning of new RPLS systems including training of operators.
We miximize the satisfaction of our clients.

RPLS can be installed during normal service hours of the engine and/or at port with no off-hire time
- 15hours engine stand-still for Crank Angle Sensor(CAS) installation
- 7 days sailing with 4men onboard for installation
- 24hours engine stand-still for pre-commissioning, switch over and commissioning
- Short commissioning voyage from port to port for validation and eventual fine-tuning or the system

Alternatively RPLS can also be installed during dry-docking of the vessel.

YOUR BENEFITS
RPLS reduces Cylinder Oil Consumption(CLO) by 30 to 50 percent leading to a remarkable reduction of total operation costs.  The system also quarantees accurate metering and precise injection of CLO into the piston ring package and the environmental benefits of reduction in solid particle emissions due to reduced lube oil consumption.

Pre-inspection report of the incoming liner is done to decide wether honing is recommended or not.

After completion of honing, the surface of cylinder liner is carefully inspected and microscopic judgement is taken in order to verify the liner micro structure.

Liner surface roughness parameters Ra, Rpk, Rvk are recorded and compared to the drawing specification.

Careful high pressure cleaning after machining is essential to remove free particles and honing grains from the liner surface and bores.

YOUR BENEFITS
• Regular honing of 4S liners will result in reduced system oil consumption
• 2-Stroke liners honing is recommended in the case of uneven or sudden wear.
• Restoring of the Wavecut shape is recommended by some makes.
