Chris-Marine® introduces Liner Condition Camera to help customers avoid costly replacement of their cylinder liners
At least 10% of newbuildings need to have their cylinder liners replaced already before the first dry-docking, a costly consequence of failing to keep the liners in top condition. However, this problem can easily be prevented with the right equipment.
-
The Chris-Marine® Liner Condition Camera
-
Wave cut grooves inside the liner
-
Tool for inserting, centering and extracting the camera.
Chris-Marine has therefore developed a Liner Condition Camera (LCC) for in situ photography of the cylinder liner walls and the exhaust valve in 2-stroke engines. The images captured by the camera (from BDC to TDC) are used to inspect and evaluate cylinder condition parameters like presence of cylinder honing marks and wave-cut groove extension, black lacquering and bore polish, size of cylinder wear edge and cleanliness of ring land. The pictures can also be used to inspect exhaust valve, fuel injector valves, lube oil injection area and start air valve.
LCC documents cylinder liner condition - in 15 minutes only - without removal of cylinder cover or exhaust valve housing. The camera detects and documents abnormal surface conditions and helps the engine crew determine if measures need to be taken. By monitoring the condition of the liner regularly, severe damage to the engine can be prevented and unnecessary investments avoided.
With the low-sulfur legislation coming into effect in 2020, cylinder condition monitoring and reconditioning is more relevant than ever. Chris-Marine offers a range of products to help ship owners with their monitoring and reconditioning challenges.
