Power management efficiency – exemple<br />
One drill<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>g rig (<st<strong>ro</strong>ng>offshore</st<strong>ro</strong>ng> or onshore) uses<br />
Diesel motor- generator sets of CAT 3512 type,<br />
1500 kVA(1050 kW), 3 x 600 V, 50 Hz.<br />
Register rule:<br />
1 drill<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>g rig = 1 Diesel motor- generator set spare part + 4 Diesel motorgenerator<br />
sets<br />
Maxim power = 2 pumps x 2 motors x 850 kW + 1 turn table x 600 kW =<br />
4000 kw<br />
Number of necessary sets for work<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>g = 4000 kW/1050 kW = 4 x CAT 3512<br />
sets<br />
About parameter <st<strong>ro</strong>ng>and</st<strong>ro</strong>ng> depth drill<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>g is possible a necessary power less<br />
3000 kW.<br />
Classical solution<br />
1 set rested <st<strong>ro</strong>ng>in</st<strong>ro</strong>ng> operation, no-load : consumption = 500l/h oil gas<br />
Power management solution<br />
- equilibration of work time of motors on the rig<br />
- economies of 500 l oil gas /h/set<br />
- decreas<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>g with 30% the ma<st<strong>ro</strong>ng>in</st<strong>ro</strong>ng>tenance cost<br />
- at 5 sets, 1 set rest spare.
