We could also use Line Guarantee AND Trip Guarantee.

If you get awarded a Monthly Line that is 87 pay hours, then you should get 87 hours of pay, as a minimum...Line Guarantee.

Also...
If you get a 60 day line, with 3 Trips (typical for 60 day lines) of 50/50/50 pay hours, then you should get 50 hours of pay FOR EACH TRIP. If you are taken off one of your Trips, for, say, OE, and given a new Trip of 30 pay hours, then you should still get 50 hours of pay for that Trip.

Sometimes, you individual Trip Rig Guarantee will pay the most, other times your Line Guarantee will pay the most, and still others your Daily Rig guarantee will pay the most.
