I would be shocked if a list like you are describing existed in the public space.

In my experience, companies keep their own vendor lists and decide who is preferred based on their own ranking system.

I wouldn't see that data being freely available but I'm sure somebody has and sells it. Its very common in manufacturing to share preferred vendor lists, blacklists, and even subcomponent pricing between suppliers/customers, so it makes sense that somebody has built a business around collecting, repackaging, and selling it. Its just another form of data-mining.

I would guess that anyone catching wind of something like that would start shipping out defamation lawsuits.

This is one of the reasons why HR departments have not provided detailed personal file information for decades.

I don't know if I'd believe it if I found it. Some of the 'worst' suppliers at my current company were among the best at my previous company so one man's treasure is another man's trash.

Often you can find info on a company's website listing who they have provided services to in the past and you may be able to find a friend of a friend who has worked with them

truckandbus: that is what I have learned. Cater to A sometimes at the expense of B and A thinks I am good while B thinks I am terrible. And, they are both correct.

I don't know about best and worst vendors, but I do see sometimes "qualified" vendors lists in the aerospace industry.
These are vendors that have specific capabilities that the OEM has found to be acceptable for their products.
They have undergone some sort of quality control (depending on the process standard) and passed tests.
It isn't secret information. And getting on the OEM qualified vendors lists is a point of pride.
I don't know if there is something equivalent in O&G, but maybe it helps you with search terms / terminology.

A large part of it is ordering the part right.
Customer orders a car from vendor A and gets a Corolla. Efficient little cars but the customer is mighty upset that the grand piano won't fit.
Customer orders a car from vendor B; they are used to servicing contractors and deliver a pickup. Happy customer, clearly vendor B is better.

Sure the example is nuts. Next time you order a hotshot for a small package...
Medical centers use hot shots to deliver donor parts in small ice chests. They traverse narrow areas and need to get through in X time absolutely. Fast is measured in minutes.
Most of our hot shots use flatbeds. Fast is measured in hours.
Then you have big rigs.
What's small? How fast is fast?

Big suppliers have their own vendor list. They are shared with contractors before order so it is agreed upon.
Sometimes supplier's and contractor (client more generally) vendor lists conflict, so it needs some discussion rounds (procurement and commercially wise). The outcome may impact delivery and price. In general, the supplier aligns to client but keep at least two suppliers so there is competition. Otherwise it is single sourcing, and there may need to be some 'frame' agreement in place.
For long lead items, etc. usually qualified manufacturers are 'known'. For valves, control systems, small items, it varies a lot.
Also all big companies have qualification procedures, so a vendor A is kept in vendor list only if they satisfy the (re)-qualification process, audit, etc. Some suppliers have very demanding criteria. I also have to say, there is a lot of politics involved.
If I would try to obtain a list of serious vendors, I would try to obtain (unformally!) a vendor list of a oil and gas big major - just as a point of reference. But copying the vendor list for the sake of building one from scratch does not make sense to me. What works for company A does not necessarily mean success for company B. So much lessons learned, red flags, recorded incident, non conformities and those sort of things participate to the supply chain process.

Life is not about waiting for the storm to pass. It's about learning dance in the rain.

In my experience it's always best to do your own validation. With suppliers you're always trying to find the right match for your company in scale, location, lead time, price, and quality. This isn't going to be the same for everyone.
Sometimes we would even do supplier audits of their processed to make sure they were doing things according to our specifications. It takes time, but the more control and understanding you can have of suppliers, the more confidence and stronger relationship you can have with them long term.
Look at suppliers/vendors as partnerships, not just transactions.

In the UK we have FPAL which rates suppliers. I believe it is a paid service you need to subscribe to in order to access the data on suppliers. As other suggest this is just a guideline and I believe our own inhouse checks are also compelted.
