The mast is furnished with a remote operated Varco "Star Racker System" (Optional), but this system can easily be replaced by a conventional manual racking board if required.
Originally the Varco star racker system has the following set back capacity:
- 63 stands 3 1/2" drillpipe,
- 63 Stands 5" drillpipe
- and approx. 20 stands drill collars (6" to 8").
Totally 146 each stands of combined 3 ½ ", 5" drillpipe and drill collars gives a racking capacity of 4,088 m(13,400 ft).
National Oilwell, that is now manuaturing the star racker, have indicated that the racking capacity can be increased considerable by upgrading the racking table to new version with "side pockets" .

Local Electric Room (LER) are also available for sale (Optional).
