All types of ton-mile service should be calculated and recorded in order to obtain a true picture of the total service received from the rotary drilling line. There are several types of ton miles as follows; 1. Round trip ton-miles 2. Drilling or "connection" ton-miles 3. Coring ton-miles 4. Ton-miles setting casing 5. Short-trip ton-miles
Before TBM, teams worked in silos, but this collaboration allowed them to achieve significant annual run rate savings. Furthermore, using the TBM Taxonomy helped connect each IT service to Transport's three key strategic outcomes: connecting a customer's whole life, successful places for communities, and enabling economic activity.
