marine lube oil

friction at sea!

Could say more but, don't ask don't tell, you know.

Depends upon the application. The term is more often used by lubricant engineers and salespeople, and refers to the proper procedures and types of lubricants for specific applications.

Aboard a ship, the lubricants have been chosen by the shipping company in consultation with the machinery suppliers. But occasionally, some new product will show up on the market with superior qualities for a particular application. It then becomes important to ensure that the old lubricant is carefully and properly removed and that the new one is applied in exactly the prescribed manner. Sometimes a crew trained by the lubrication company or the machinery supplier will be hired in to do the job, assisted by the sailing engineers. And sometimes, when the machinery itself needs replacement, the sailing engineers will attend to the task.

In both cases, strict attention has to be paid to the method used. This attention and the correct lubrication fall under the heading of "Rationalization". Never could understand why that particular term was chosen, because it can confuse its own meaning.

I imagine the same care and attention applies to all marine applications, and all lubricant/machinery interface applications undertaken by professionals. You'd have to ask a lubricant engineer to get that information. One of my classmates has become a lubricant engineer. I'll pass this along to him to find out what he has to say.

It has always been my understanding that marine lubricants can repel water better than 'standard' lubes.they work better under heated conditions and they hold longer when over worked.

Every vessel i have been on has water in the bilge. Eventually the water gets into gears.......sometimes from the deck, sometimes from the shaft caulking seal.......sometimes from just old fashion leaks.

I have never paid much attention below deck as my concern was the gear on the deck. however, this is what I have perceived over the last 30 odd years on mid sized vessels 10-30M and 250-750 hp.

However, it will take a real Engineer to answer this fully, just like Mark said.

Mark, "stated" beautifully!

'Tis nothin than a more than a marketing thing matey.

Spill forth the exotic semi-fluid grease/oil/synthetic/Dino - arctic/mining/rock drill® (or the NASA'esque marine) products - for they can actually be used for other applications...

Advancements have been made in the development of lubricants over the last decade. Availability however is a function of available market - or is that market availability?

Thanks, Pegleg Pete!

I notice, however, that those of us who are in the great unwashed public don't get a chance to learn much about advances in lubes and synthetic oils, etc. Who needs to pick up the Public Information pace a little here?
