Facts about Ship’s Reassembling Machinery After Upkeep

Maintainingthe machinery and systems on board ships mostly require dissembling and assembling of components for repairs, cleaning, and lubricating jobs. Those with good hands-on experience of repairing ship’s machines have an idea that dissembling machinery is much easier as likened to getting it reassembled. Among the plenty essential things that has to be borne in mind is to ensure that the right component of the machinery is being fitted at the right position during reassembling.

Provided below are ten things that maritime professionals must know while reassembling any machinery that are on board ships

  1. Read and study the Manual correctly before beginning the Process: Be sure that you are thorough with the manual of the machinery before you actually commence the process of maintenance. You should know which part goes where and the sequence of inserting components during reassembling.Place the manual always by your side. Additionally,when in doubt ask your colleagues rather than assuming, oftentimes you might have to perform out the whole process again.
  • Use a Base for Components: While overhauling any machinery, it isadvisable to use brown paper/ cardboard/ wooden plank to store all the removed components over it. While assembling it back, it will be quite easy to figure out if you have left or missed any component during reassembling. Ensure you do not lose any component during the overhauling process.
  • Take Note of the Markings: Most machinery components normally come with markings for alignment especially during assembly. Be sure to insert the components and align them following the markings.
  • Ensure everything is well cleaned, Don’t Miss Out: Take note of everything that you have to do before overhauling the machinery to be  sure that you do not miss anything. Equally ensure that all the internal components are cleaned off carbon deposit, soot oil or grease before putting them back.
  • Check yourrecords: Check your previous records before renewing units and parts, particularly bearings and bolts for under or oversize aspects. This is vital to ensure that you have the right size of spare parts during the overhauling process.
  • Inspect  for Defects: Be sure that all the assembling components/ spare parts of the machinery are dully tested or do not have any defects. This is vital to forestall any breakdown in the near future.
  • Keep Check on The Torque: Be sure that the assembled parts are tightened as per the needed torque offered in the manual. Over or under-torque can leadto breaking or loosening of the components after restarting the machinery.
  • Don’t forget Any Parts Inside: Before coupling up the machinery, check all the internal components/ space/ crank case/ gear case of the machinery for any leftover tools, rags etc. and take them out if discovered.
  • Open Valves, Inspect Oil/Water Levels: Once the machinery has been fully assembled, Be sure to open all the isolated valves and inspect oil/water levels before igniting it. One must equally know the right steps to restart the machinery.
  1. Inspect for Any Abnormality: The machinery should be allowed to operate for short period before getting it fully operational. During this short period, following things are to be inspected: vibrations, vital parameters, sounds and any other abnormality. If any issue is found, the machine should be stopped immediately afterwards and its cause should checked out by opening the machinery again.
