welcome to the forum " pare ko" This is a very useful forum I assure you that.

I think I have to recalibrate my brain from metric to English unit because I have to pause for a while to convert every number but I will get along I just need little time. i find all information here as very helpful kudos to everybody

we use unitor equipment onboard and the central distribution pipes are all stainless still so I'm not worried and besides the ships is already 10 years old . but i have to admit reading so much information sometimes scares me even though i am in this job for 20 years

Though the major welding job will be done by the shipyard the ship's crew would do some of the minor jobs (well its not a minor job as I see it) like overhauling our 7500 hp main engine, that's our major c...
