Cylinder condition specialist Chris-Marine is to launch an app that it says will ensure that cylinder honing is performed efficiently and to engine companies’ specifications.
The company, which offers a range of cylinder honing, cleaning and monitoring equipment, is due to launch the app in March. It will be operated from a Windows-based tablet and will be available to support Chris-Marine’s entire portfolio of honing products.
The app collects measured geometrical dimensions and surface roughness values and guides the user through the honing process. The data collected is then summarised in a measurement report. A set of pre-defined ‘recipes’ for engine makers’ cylinder requirements and measurement report formats are included in the app. Best practice, report formats and honing recipes can be updated remotely by Chris-Marine.
Chris-Marine chief technology officer Daniel Grunditz said that the company already has several prototypes in operation with leading workshops. He explained that the idea behind the app had come from another condition monitoring device the company had developed, the liner diameter measurement (LDM) tool.
“We started looking at our workshop tool portfolio and realised that although we were very big in honing we didn’t supply a tool that makes it possible to monitor the process. It’s very likely that our customers are not following a standard procedure, they are all on their own.”
Honing is a complicated procedure that involves three types of honing stones with up to five grades of surface roughness alongside multiple other parameters including speed, stone pressure and number of strokes for each stage. Engine companies have very detailed honing specifications that workshops are required to meet by their shipowner customers.
Mr Grunditz reported that sales of the LDM tool had surged over the past three years, driven by technological improvements and challenging cylinder conditions brought about by the rise of cold corrosion. The device, which can tell operators when engine liners need to be honed or replaced, is typically used by shipowners when working with new engines or by maintenance teams preparing for drydocking.
