The Metalock Engineering Group have carried out successful diesel engine reconditioning and repair for over 70 years on all types of engines.
Endless running times to meet the ever-increasing demands for power means that engine availability is a critical requirement, however, there are times when things don’t always go to plan and even the best-maintained engines can break down and it is always at the most inconvenient time.
Diesel Engine -Block - Upper and Lower Liner Landings
Diesel Engine – Main Bearing Pocket Transplant - Metal stitching
Typical examples of what we can do in this area are:
Cracked or broken diesel engine bedplates and entablatures are routinely repaired by Metalock, often after a catastrophic failure and returned to full-service condition Class Approved in a very short time saving the need for costly replacement.
Onsite diesel engine repair can be carried out by Metalock at sea, alongside or in a drydock or a power generation plant. Anywhere, anytime.
We work directly for companies involved with power generation from land fill gas, Industrial power generation for paper mills, factories, petrochemical plants.
We work on offshore installations (production platforms or drilling rigs) as well as all types of marine vessels. Merchant and Naval - wherever the engine is located we can get there if required.
Many diesel engine manufacturers have circulated Service Bulletins to their customers warning them of this condition and advise methods to avoid or minimise failures.
When medium speed four stroke engines have accumulated in the region of 60,000 running hours there is a condition that can develop that is sometimes described as the “cam effect” or “ridge wear”.
This develops over a period of time and can be identified as a protruding band that goes around the circumference of the crankpin diameter that can lead to the failure of the crankpin bearing sometimes causing disastrous results.
The effect can cause an extensive build-up of heat which in turn can harden the crankpin diameter causing problems in lubrication and possible crankpin bearing failure.
If no action is taken to rectify this effect a failure may occur.
With over 50 years experience in the marine & offshore industry,
you can rely on Metalock with your Diesel Engine repair or overhaul.
A conrod breaks through the crankcase means a damaged big end bearing diameter, a broken conrod, balance weight damage together with broken studs. Damage on the lower part of the liner – or worse.
Entablature damage, hole in the water jacket as well as a hole in the crankcase - all this explains the term catastrophic failure! Does it mean a new crankshaft or a new engine block? NOT ALWAYS and that’s where the Metalock Engineering Group can help.
Don’t worry we are just a phone call away.
We are on call 24 hours daily 7 days a week. With technicians strategically located throughout our global service centres, and available at short notice to travel anywhere in the world, we are organised to provide a rapid response service to deal with emergency breakdowns 365 days of the year.
All personnel are familiar with onshore and offshore working environments and demands placed upon them to achieve program and get the job done in a safe and efficient manner.
