inglés al español Técnico/Ingeniería Ciencia/ Ing. del petróleo Casing hand thanked me for showing him the right way of doing the job.

Hello, I have a doubt with this word but I'm not sure about it.
I translated as:

El empleado de maniobrar la TR me agradeció por mostrarle la forma correcta de hacer las cosas...

and this is the original text:

Casing hand thanked me for showing him the right way of doing things and for also keeping an eye on him, said he would dope the pipe in the Laydown trough.

The text is about a casing running. I will appreciate your help, thanks.
