Reduced Diesel Fuel Consumption
The primary application of CleanDesign’s hybrid energy management system (hEMS) is to reduce diesel fuel consumption by drilling rigs in the oil and gas industry. The system saves over 100,000gal of diesel per year per drilling rig. Fuel savings are even higher at sites that have field gas available and generator dual fuel kits.
In addition to fuel savings, downtime caused by unscheduled mechanical issues with the generators or a generator faulting mid-operation is avoided. The battery energy storage provides additional power when needed. In the example below, hEMS allowed the rig crew to continue drilling instead of circulating and taking downtime.
The figure below shows an additional example where the rig crew was alerted of a genset fault. hEMS supported the rig demand while rig personnel resolved the issue.
Support Best Operating Practices
A standard feature of the hybrid energy management system is professional data monitoring, especially risk factors that can blackout a drilling rig.
Customers receive 24/7 access to genset data from their drilling rigs. System alerts are generated if gensets operate outside of recommended parameters, helping the rig crew to schedule maintenance and react quickly to resolve issues before a problem occurs.
Specific data is provided to help the rig crew and 3rd party technicians to more rapidly diagnose issues, organize the right people to come to site, and confirm that issues are resolved.
hEMS runs gensets at optimal levels for both reduced fuel consumption and reduced emmissions.
- Particulate matter (PM) reduced by over 40%
- Carbon monoxide (CO) reduced by over 30%.
- 100,000gal of diesel fuel savings avoids the release of more than 1,355 tonnes of CO2 per year per rig.
Reduced Genset Runtime Hours
With hEMS, gensets run for fewer hours. For example, 24 days of combined runtime (over 3 gensets) has been saved in only one month. Less genset runtime hours extend (i) maintenance intervals and (ii) the timeline before gensets need to be overhauled or replaced.
