Abstract:
A method of remotely determining an existence of a varying cross-load applied to a derrick of a mobile repair unit for a well, said method comprising the steps of:monitoring a first parameter that varies with a first force exerted at a first point, said first force varying as a function of said cross-load;monitoring a second parameter that varies with a second force exerted at a second point spaced apart from said first point, said second force varying as a function of said cross-load;storing a first digital value representing said first parameter;storing a second digital value representing said second parameter;communicating said first digital value and said second digital value to a remote location by way of a modem; andcomparing, at said remote location, said first digital value with said second digital value to determine a difference therebetween, said difference being an indication that said cross-load exists.
