Load Banks In The Oil & Gas Sector
Crestchic has many years experience in testing and commissioning in the oil and gas industries and has been involved in large projects around the world and has recently successfully completed a 50MVA test for an onshore oil pumping station in the Far East.
- Commissioning turbines destined for offshore use using load banks is essential, as a failure can be difficult and expensive to rectify once the platform is at sea.
- Loss of production revenue can be millions of dollars.
- The testing involves incremental steps up to full load, to check turbine parameters for both fuel consumption and different types of fuel. In addition, monitoring vibration, temperature and airflow will ensure peak efficiency once the facility is on station and working to capacity.
- At the same time, it is possible to simulate the effect of a large block load being introduced or withdrawn, e.g. a pump or compressor, measuring the recovery interval (‘transient response’) until the engine speed returns to normal.
- This mitigates against the risk that the engine does not recover and the alternator fails.
- Decommissioning – not sufficient load for existing generation equipment, which cannot be replaced out. Load banks can be used to ensure efficiency of equipment.
Data Center World Build Conference: My five top takeaways
In May 2023, Crestchic participated in the first-ever Data Center World Build Conference in Austin, TX. Steven Bacon, Business Development Manager at Crestchic, shares his five top takeaways from the event. Efficiency is key: During the two-day conference, there was...
WHY USE A LOAD BANK?
Load banks are primarily used for testing electrical power output on diesel generators, gas turbines and UPS systems whilst carrying out commissioning and maintenance work.
The load banks are used for simulating real electrical loads enabling essential setup and commissioning which ensures that all electrical and control parameters are met prior to power generation/back up equipment being energized on line.
