Large Diesel Engine Repairs

Diesel Engine Repairs for the Marine and Power Generation industries

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.

Onsite Diesel Engine Repair

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.

Diesel Engine Block - Upper and Lower Liner Landings

Typical Repair Examples

Typical examples of what we can do in this area are:

• Cold Metalock cast iron repairs on cracked or broken engines and associated components (metal-stitching)
• Main bearing pocket transplants
• Machine the main bearing and big end journals while the crankshaft is still in the engine using orbital machining equipment
• Refurbishment of upper/lower cylinder liner landing face and bore areas
• Metal spray and re-machine badly worn, upper liner landing surfaces
• Engine in line boring main bearing pockets
• Engine alignment
• Fusion welding of diesel engine cylinder heads
• Reconditioning of pistons, valves, and seats
• Crankshaft straightening in situ
• Crankshaft heat treatment in situ to reduce hardness values

Offshore Industry

We have been carrying out successful diesel engine repairs since the early 1940s and we have been involved in offshore repairs since the early 1970s. We have completed repairs for most of the offshore operators around the world and we have a long and proven track record in this specialised field of expertise.

With technicians strategically located throughout the Metalock Engineering Group always 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.
